Ultra-High Performance Liquid Chromatography-Mass Spectrometry for the Investigation of Organic and Bioorganic Compounds. Prof. A. Padarauskas, Assoc. Prof. V. Olšauskaitė.

The chromatographic determination of anionic, cationic and neutral analytes on bare silica stationary phase in hydrophilic interaction chromatography mode has been developed. The effect of various parameters on the peak shapes of small polar compounds in hydrophilic interaction chromatography on the two stationary phases (bare silica and amide-bonded silica) was described. The overloading behaviour of charged acidic (acetylsalicylic acid and nicotinic acid) and basic (creatinine and 1-ethyl-2,3-dimethylimidazolium) solutes was investigated on two stationary phases (bare silica and amide-bonded silica) in the hydrophilic interaction chromatography separation mode at three mobile phase pH values (3.0, 5.0 and 7.0).

A newly developed amperometric glucose biosensor based on graphite rod (GR) working electrode modified with biocomposite consisting of poly (pyrrole-2-carboxylic acid) (PCPy) particles and enzyme glucose oxidase (GOx) was investigated. The PCPy particles were synthesized by chemical oxidative polymerization technique using H2O2 as initiator of polymerization reaction and modified covalently with the GOx (PCPy-GOx) after activation of carboxyl groups located on the particles surface with a mixture of N-(3-dimethylaminopropyl)-N-ethylcarbodiimide hydrochloride (EDC) and N-hydroxysuccinimide (NHS). Then the PCPy-GOx biocomposite was dispersed in a buffer solution containing a certain amount of bovine serum albumin (BSA). The resulting biocomposite suspension was adsorbed the on GR electrode surface with subsequent solvent airing and chemical cross-linking of the proteins with glutaraldehyde vapour (GR/PCPy-GOx). It was determined that the current response of the GR/PCPy-GOx electrodes to glucose measured at +300mV vs Cl reference electrode was influenced by the duration of the PCPy particles synthesis, pH of the GOx solution used for the PCPy particles modification and the amount of immobilized PCPy-GOx biocomposite. Chemical synthesis of the conducting polymer polypyrrole induced by [Fe(CN)(6)](3-) is reported. Reaction kinetics was characterized spectrophotometrically.

Gas Chromatography. Prof. V. Vičkačkaitė.

Headspace gas chromatographic analysis is suggested for the determination of acetic and propionic acids in aqueous media. Derivatization of the acids was accomplished by tributyl borate. The derivatization and headspace extraction were coupled into a single step. Analytical characteristics of the suggested technique at the optimized derivatization/headspace extraction conditions were determined. The technique was applied for the analysis of bakery products, ketchup, tomato paste and kefir. A home-made silica-based silver ion solid-phase extraction (Ag+-SPE) system for the fractionation and subsequent gas chromatographic analysis of trans fatty acids in human adipose tissue is developed and examined.

Investigation of Instrumental Methods of Analysis of Environmental, Industrial, Biological and Cultural Heritage Objects. Prof. S. Tautkus.

GDC powders with Gd content of 10, 15 and 20 mol% were synthesized by aqueous sol-gel and sol-gel combustion methods using glycerol as complexing agent and fuel. The phase purity and structural features of obtained powders were evaluated using X-ray diffraction analysis and Raman spectroscopy. These studies confirmed that crystallization of GDC occurs into cubic fluorite-type crystal structure. Morphological features as well as optical properties of GDC powders were determined to be strongly dependent on the synthesis method. To confirm chemical composition of prepared samples, spectrophotometric approach for the determination of Ce and Gd in GDC samples was suggested. Relative standard deviation values for Ce and Gd were in the range of 1.5-4.1 and 2.0-5.6%, respectively. The obtained results demonstrated that the suggested analytical procedure can be successfully used for the analysis of GDC specimens with high accuracy.

Rare Earth and Transition Metal Doped Phosphors. Assoc. Prof. A. Katelnikovas.

The structural evolution between the monoclinic (layered-perovskite) and cubic (pyrochlore) structures is studied for the complete series of La2-xErxTi2O7 synthetized by solid-state reaction. A partial solid solution with layered perovskite structure is achieved until x=0.10. The luminescence properties of these oxides show a low quantum efficiency and the concentration quenching is observed for x=0.10. However, La1.9Er0.1Ti2O7 oxide exhibits interesting UpConversion (UC) properties at multiple excitation wavelengths (784, 808 and 980 nm). Laser power studies have demonstrated a two-photon upconversion process for 808 and 980 nm excitations. Moreover, the measurement of the lifetimes on the F-4(9/2) -> I-4(15/2) and S-4(3/2) -> I-4(15/2) transitions makes it possible to identify an Energy Transfer (ET) mechanism. Photochemically synthesized CeO2 nanoparticles were applied as photoactive compounds in order to generate formation of metallic silver nanoparticles. Irradiation of deaerated CeO2 suspensions in the presence of Ag+ resulted in the rise of a strong surface plasmon resonance band with a maximum at 393-422 nm in the absorption spectra of the solutions, indicating formation of small metallic silver particles. Faster formation of Ag nanoparticles with the lower amount of silver precursor being required was observed when ethanol was introduced to the reaction solution before the irradiation. This implies that oxidative reactions can be strongly suppressed in deaerated ethanol containing solutions with respect to the pure aqueous media.

Synthesis, Characterization and Analysis of Functional Materials. Dr. A. Žarkov.

Novel synthetic approach for preparation of single phase porous SnO2 thin films with controllable grain size and porosity has been developed. The entire process requires neither organic solvents nor addition of any complexing agent. The thin films were deposited using the spin coating technique from an aqueous solution prepared by dissolving tin(II) oxalate in hydrogen peroxide. X-ray diffraction analysis showed that the deposited films are single-phase and their crystallite size increases as the annealing temperature is increased from 300 to 800 degrees C. It was also found that the films exhibit a preferred (110) orientation of the crystallites. Magnetic properties of new multiferroic BiFe0.5Sc0.5O3 perovskite which exists in two different orthorhombic polymorphs, the antipolar Pnma and the polar Ima2, were studied using a SQUID-magnetometer technique in magnetic fields up to 50 kOe in the temperature range of 5-300 K. Both polymorphs show a weak ferromagnetic component below the Neel temperature, T-N similar to 220 K.

Tungsten trioxide (WO3) and molybdenum-doped tungsten trioxide (WO3:Mo) films were deposited on stainless steel surface by a chemical aqueous solution approach using dip-coating technique. The deposited 5, 10 and 15-layer films were homogeneous and continuous. The surface morphology and crystallinity of the produced films were dependent on the metal cation species and concentration of PVA in the solution. FE-SEM analysis revealed the formation of textured WO3 film surfaces having spike-like nanostructures. The values of the static water contact angle measured on the film surface showed that deposited WO3 films can exhibit both hydrophilic and hydrophobic nature, while WO3:Mo films showed hydrophilic behavior. Tribological properties of the deposited films were evaluated in deionized water. All three coatings retained a lubricating layer much better than original steel, demonstrating major reduction in friction and wear. Particularly effective were PVA-free WO3 films, whose friction coefficient stayed under 0.2 for over 2000 cycles. Excellent tribological, hydrophobic and hydrophilic properties along with simple deposition methods suggest very promising potential of WO3 and WO3:Mo coatings in industrial applications.

Synthesis of Calcium Phosphates by Sol-Gel Method. Ž. Stankevičiūtė.

Beta-Tricalcium phosphate (beta-Ca-3(PO4)(2), beta-TCP) powders were synthesized using wet polymeric precipitation method for the first time to our best knowledge. The results of X-ray diffraction analysis showed the formation of almost single a Ca-deficient hydroxyapatite (CDHA) phase of a poor crystallinity already at room temperature. With continuously increasing the calcination temperature up to 800 degrees C the crystalline beta-TCP was obtained as the main phase. It was demonstrated that infrared spectroscopy is very effective method to characterize the formation of beta-Ca-3(PO4)(2). The SEM results showed that beta-Ca-3(PO4)(2) solids were homogeneous having a small particle size distribution. The (beta-TCP powders consisted of spherical particles varying in size from 100 to 300 nm.

Upconverting Nanoparticle Synthesis. Study of Optical Properties and Biocompatibility of Na(Gd/Y)F4 Nanoparticles. Prof. S. Šakirzanovas.

We explore a possibility to apply ultrafast 3D laser nanolithography followed by heating to acquire ceramic 3D structures down to micro-/nano-dimension. Laser fabrication is employed for the production of initial 3D structures with varying (ranging within hundreds of nm) feature sizes out of hybrid organic-inorganic material SZ2080. Then, a post-fabrication heating at different temperatures up to 1500 degrees C in an air atmosphere facilitates metal-organic framework decomposition, which results in the glass-ceramic hybrid material. Additionally, annealing procedure densifies the obtained objects providing an extra route for size control. As we show, this can be applied to bulk and free-form objects. We uncover that the geometric downscaling can reach up to 40%, while the aspect ratio of single features, as well as filling ratio of the whole object, remains the same regardless of volume/surface-area ratio. The structures proved to be qualitatively resistant to dry etching, hinting at significantly increased resiliency. Finally, Raman spectrum and X-ray diffraction (XRD) analysis were performed in order to uncover undergoing chemical processes during heat-treatment in order to determine the composition of material obtained. Revealed physical and chemical properties prove the proposed approach paving a route towards 3D opto-structuring of ceramics at the nanoscale for diverse photonic, micro fluidic and biomedical applications.

Synthesis and Investigation of Different Metal Molybdates, Vanadates, Tungstates and Phosphates. Assoc. Prof. A. Žalga.

Nano- and micro-sized La2Mo2O9 ceramics have been successfully synthesized by an aqueous sol-gel synthesis method using a tartaric acid as a ligand. Thermal analysis of both as-prepared La-Mo-O tartrate gel precursor and La2Mo2O9 double oxide heat-treated at different temperatures was performed. The high-temperature phase transition from alpha to beta-phases was additionally investigated by broadband high-temperature impedance spectroscopy techniques. The alpha a dagger" beta phase transition was characterized by monitoring the conductivity and a transfer of heat with respect to temperature. The crystalline phase stability of monoclinic La2Mo2O9 compound was confirmed by x-ray diffraction measurements, while the dense nanoscale surface composed of the particles, ranging from 50 to 100 mu m, was confirmed by scanning electron microscopy.

Red pigments and binding media used in ancient manuscripts for rubrication and illumination were investigated. The commercial compounds were analysed with the aim to create a short data library which could be used for the characterization of different model compositions of red pigments and dyes. Finally, these analytical data will be used for the identification of specimens obtained from ancient manuscripts. The red pigments and binding media were characterized using Fourier-transform infrared spectroscopy (FTIR), scanning electron microscopy coupled with energy-dispersive X-ray spectroscopy (SEM/EDX), X-ray diffraction (XRD) analysis and thermal (TG/DSC) analysis techniques.

Basic Investigation of Sodium and Lithium Ion Electrochemical Energy Storage Systems Using Structural Analysis, Electrochemical and Molecular Modeling Techniques. Assoc. Prof. Dr. L. Vilčiauskas.

Li1+xTi2O4 spinel structures are used as model systems to study the complex environment of electrode/electrolyte interfaces in lithium-ion batteries. The lithiation pathways and the potential dependence of delithiation on the corresponding Li1+xTi2O4 surfaces were explored using the density functional theory. Low-index surfaces are found to be highly reactive, with Li forming a fully lithiated phase (Li2Ti2O4) before more Li can penetrate farther into the bulk. The calculated activation energies for the formation of Li2Ti2O4 at the surface are found to be much lower than those for Li diffusion through LiTi2O4, suggesting that a two-phase lithiation process takes place during cycling. Additionally, the delithiation reaction mechanism in Li2Ti2O4 is studied by evaluating the free energies for Li+ transfer to an ethylene carbonate electrolyte by employing a Born-Haber thermodynamic cycle. The effects of an applied (external) potential are effectively incorporated into the thermodynamic cycle and provides the means to calibrate the bias potential to the experimentally known scale. Finally, the effects of an applied electrode potential are studied on the Li2Ti2O4 delithiation energetic pathways in various environments, emphasizing the different contributions to the charge-transfer energetics in these electrode materials.

The nanocomposite coatings made using graphene oxide (GO) and six different organic dyes were used to produce the laser-induced graphene (LIG) coatings by means of near infrared picosecond laser irradiation. The coatings were investigated by means of contact angle measurement with three liquids (1-bromonaphtalene, glycerol and water), Raman spectroscopy, scanning electron microscopy, Fourier transform infrared (FTIR) spectroscopy and thermogravimetric analysis. It was found that the more hydrophilic is the precursor surface the more hydrophobic LIG surface is produced after the laser treatment. Contact angle values obtained on LIG produced from pure GO reached 143 degrees. FTIR spectra have shown that the interaction between GO and dye molecules is realized through the nitrogen atoms. Raman spectra have shown that the best quality LIG coating is obtained using a GO-neutral red nanocomposite precursor. A correlation among contact angle, Raman spectra and topological indices of dye molecules were found, and will serve for the further investigation of the mechanism of LIG production and development of low-defect coatings.

Synthesis and Application of Nanomaterials. Prof. A. Beganskienė.

Surfactants are one of the materials recommended for the cleaning of movable cultural properties. These substances are widespread in other fields - medicine, cosmetics, household appliance industry, etc. Quaternary ammonium compounds are particularly prevalent due to their cleansing and disinfectant properties. Initial studies have shown that surfactants, including quaternary ammonium compounds, have a positive effect on preserved/restored cultural properties. Using relatively low concentrations of aqueous solutions of these substances, it is possible to obtain sufficiently good results to wash out from the restoration of the document or textiles dirt, acidification of the object and colour changes that cause aging and decomposition processes - hydrolysis and oxidation. The chromium-doped (0-20 mol% of Cr3+) garnet structure materials Y3Ga5O12 (YGG) and Gd3Sc2Ga3O12 (GSGG) were synthesized via aqueous sol-gel combustion (SGC) method.

We have successfully prepared and structurally characterized five novel tin(IV) heteroleptic N,O-beta-heteroarylalkenolates containing -CF3 groups. The synthetic route used reactions of Sn(OtBu)(4) with 3,3,3-trifluoro(pyridin-2-yl)propen-2-ol (PyTFPH), 3,3,3-trifluoro(dimethyl-1,3-oxazol-2-yl)propen-2-ol (DMOTFPH), and 3,3,3-trifluoro(1,3-benzthiazol-2-yl)propen-2-ol (BTTFPH) in dry aprotic solvents leading to elimination of tert-butanol and formation of Sn(OtBu)(2)(PyTFP)(2) (1), Sn(OtBu)(2)(DMOTFP)(2) (2), and Sn(OtBu)(2)(BTTFP)(2) (3). The chelating ligands employed a bidentate N boolean AND O donor set. The reactivity of OtBu groups in the obtained Sn(OtBu)(2)(N boolean AND O)(2) complexes was further investigated in reactions with fluorinated alcohols, 2,2,2-trifluoroethanol (TFEH) and 1,1,1,3,3,3-hexafluoro-2-propanol (HFPH). Two complexes Sn(TFE)(2)(DMOTFP)(2) (4) and Sn(HFP)(2)(PyTFP)(2) (5) were obtained and structurally characterized. Thermal behavior of complexes 1-5 was studied by thermogravimetry and differential scanning calorimetry (TG/DSC). The most volatile compounds Sn(OtBu)(2)(PyTFP)(2) (1) and Sn(OtBu)(2)(DMOTFP)(2) (2) were chosen and tested in a PI-MOCVD process for the SnO2 growth on sapphire-C substrates. Film growth rates at different temperatures (500-900 degrees C), crystalline quality, surface roughness, transparency in UV/Vis-mid-IR spectral ranges have been investigated. The results showed that these two compounds are suitable precursors for MOCVD deposition of high quality SnO2 films. Fabricated films displayed good response to CO and NO2 in chemo-resistive gas sensing measurements. The results of fabrication of nanostructured La1-x Sr (x) MnO3 films grown by pulsed injection metalorganic chemical vapour deposition technique onto special disordered glass-ceramics substrate are obtained.

Synthesis and Characterization of Luminescent Materials. Assoc. Prof. R. Skaudžius.

Mg-3/Al-1 and Mg3Al1-xTbx layered double hydroxides (LDHs) intercalated with terephthalate anion were synthesized using sol-gel method. The obtained materials were characterized by X-ray diffraction (XRD) analysis, infrared (FTIR) spectroscopy, fluorescence spectroscopy (FLS) and scanning electron microscopy (SEM). The Tb3+ substitution effects in the Mg3Al1-xTbx LDHs were investigated by changing the Tb3+ concentration in the cation layers. The study indicates that the organic guest-terephthalate in the interlayer spacing of the LDH host influences the luminescence of the hybrid inorganic-organic materials. Terbium Tb3+ and europium Eu3+ metal-organic frameworks (MOFs) based on 2,3,5,6-tetrafluoro-1,4-benzenedicarboxylic acid (TFBDC) were synthesized by precipitation and diffusion controlled precipitation methods.

Development of Sol-Gel Synthesis Method for the Preparation of Mixed-Metal Oxides. Prof. A. Kareiva.

Cobalt chromite based pigments CoCr(2-x)Ln(x)O(4) (Ln=Tm3+ and Yb3+) with different substitutional level of lanthanide (x=0-0.5) have been synthesized using aqueous sol gel synthetic approach. The XRD analysis revealed that single phase spinel was obtained only with low content of lanthanide ions (x=0.01-0.04). The sol gel derived powders with higher concentration of lanthanide (x=0.05-0.2) contained minor amount of orthochromite phase. At the highest substitutional level (x >= 0.2) the perovskite phase became the main crystalline phase. The colour of obtained pigments and corresponding ceramic glazes were analogous. Depending on the dominant phase, the colour varied from bluish-green (prevailing spinel phase) to dark brownish green (the main perovskite phase). This study proved that the replacement of chromium ions by thulium and ytterbium was successful at low content of lanthanides influencing the shade of pigment and corresponding glazes. Sm3+-Doped and Eu3+/Sm3+-co-doped yttrium aluminium garnets (YAG) have been synthesized by an environmentally friendly sol-gel method.

Utilization of "dark'' triplet states is a key task for design of novel emissive organic compounds. Thermally activated delayed fluorescence (TADF) and room temperature phosphorescence (RTP) are two promising pathways to employ triplet excitons and reach high internal quantum efficiencies. In this paper we present a series of carbazole-pyrimidine cored compounds, showing RTP and TADF. A specific energy level scheme was shown to promote intersystem crossing and RTP in carbazole-pyrimidine derivatives with phosphorescence quantum yield values of up to 0.07 in rigid Zeonex films. The modification of the acceptor core with 2-methylthio and dimethylamine fragments allowed us to reduce the singlet-triplet energy gap, enhance the rISC (reverse intersystem crossing) rate and obtain high intensity TADF with a fluorescence quantum yield of up to 0.32. Time resolved fluorescence analysis revealed the presence of conformational disorder of the donor-acceptor core governing TADF properties in solid films. Despite apparent similarity, two isotopomers of acetonitrile (ACN-h(3) and ACN-d(3)) show unexpected differences in their structural and dynamic properties. These differences cannot be fully understood within the usual isotope effect and therefore called as unresolved casus. Sensing the solvent properties, the H-bond dynamics of picolinic acid N-oxide (PANO) in ACN was studied using H-1 and O-17 NMR. Several overlapping factors, like the presence of micro-traces of water, liquid-liquid equilibrium, effect of ionic ingredient, etc., which may cause the observed anomalies in the dependences of PANO chemical shift and signal width on temperature, were analyzed.

The influence of different chemical composition and physical properties of olive oils on their tribological performance and corrosion protection has been investigated. The chemical composition was determined by means of IR, H-1 and C-13 NMR spectroscopy. The investigated olive oils show small quantitative and qualitative differences between each other (the amount of free fatty acids and the composition of fatty acids in triglycerides). The spectroscopic data let us unambiguously determine in general that the main fatty acids in oils are saturated palmitic and/or stearic acids, unsaturated oleic and linoleic acids except linolenic acid.

S-adenosyl-L-methionine-dependent 2'-O-methylation of the 3'-terminal nucleotide plays important roles in biogenesis of eukaryotic small non-coding RNAs, such as siRNAs, miRNAs and Piwi-interacting RNAs (piRNAs). Here we demonstrate that, in contrast to Mg2+/Mn2+-dependent plant and bacterial homologues, the Drosophila DmHen1 and human HsHEN1 piRNA methyltransferases require cobalt cations for their enzymatic activity in vitro. We also show for the first time the capacity of the animal Hen1 to catalyse the transfer of a variety of extended chemical groups from synthetic analogues of the AdoMet cofactor onto a wide range (22-80 nt) of single-stranded RNAs permitting their 3'-terminal functionalization and labelling. Moreover, we provide evidence that deletion of a small C-terminal region of the DmHen1 protein further increases its modification efficiency and abolishes a modest 3'-terminal nucleotide bias observed for the full-length protein. Finally, we show that fluorophore-tagged ssRNA molecules are successfully detected in fluorescence resonance energy transfer assays both individually and in a total RNA mixture.

Al2O3/ZnO nanolaminates were evaluated for possible application in the design of optical immunosensors. Total internal reflection ellipsometry (TIRE) was utilized to study the optical response during the formation of a bovine serum albumin (BSA) based monolayer on the surface of Al2O3/ZnO nanolaminates, which were pre-modified with a N-(3-aminopropyl)triethoxysilane (APTES) layer. The influence of the thicknesses of Al2O3 and ZnO layers on the performance of Al2O3/ZnO nanolaminate based structures has been assessed. The metabolism of yeast cells (Saccharomyces cerevisiae) was utilized for the synthesis of the conducting polymer - polypyrrole (Ppy).Yeast cells were modified in situ by synthesized Ppy. The Ppy was formed in the cell wall by redox-cycling of [Fe(CN)(6)](3-/4-), performed by the yeast cells. Fluorescence microscopy, enzymatic digestions, atomic force microscopy and isotope ratio mass spectroscopy were applied to determine both the polymerization reaction itself and the polymer location in yeast cells. Ppy formation resulted in enhanced resistance to lytic enzymes, significant increase of elasticity and alteration of other mechanical cell wall properties evaluated by atomic force microscopy (AFM). The suggested method of polymer synthesis allows the introduction of polypyrrole structures within the cell wall, which is build up from polymers consisting of carbohydrates. This cell wall modification strategy could increase the usefulness of yeast as an alternative energy source in biofuel cells, and in cell based biosensors.

Among W alloys, Fe-W has seen much attention recently, due to the need of moving toward the design of environmentally friendly materials. Coatings with 4, 16 and 24 at.% of W were electrodeposited from an environmental friendly Fe(III)-based glycolate-citrate bath. The samples were annealed in vacuum at different temperatures up to 800 degrees C. Different crystalline phases are formed upon annealing: alpha-Fe, Fe2W, Fe3W3C, Fe6W6C, and FeWO4. Their grain size and distribution within the coating was studied by means of Electron Backscattered Diffraction (EBSD) technique. The effect of annealing on the mechanical properties of the coatings was analyzed performing nanoindentation measurements. The results show a considerable increase of the hardness followed by a rapid decrease at higher temperatures. The highest hardness value, i.e. 16.5 GPa, is measured for the sample with 24 at.% of W after annealing at 600 degrees C owing to the precipitation of alpha-Fe crystallites. This study indicates the possibility to substantially increase the hardness of electrodeposited Fe-W coatings by optimization of the annealing treatment.

Hybrid bilayer lipid membrane (hBLM) was assembled on a mechanically polished metallurgical titanium plate. Hydrophobic molecular anchors needed for phospholipid overlayers were obtained by silanization of the Ti surface with octadecyltrichlorosilane (OTS). The formation of hBLM was accomplished by fusion of the multilamellar vesicles containing of 1, 2-dioleoyl-sn-glycero-3-phosphocholine (DOPC) and cholesterol (Chol) at molar % ratio 60/40. The fusion process was monitored in real-time by the dynamic fast Fourier transformation (FFT) electrochemical impedance spectroscopy. We found that the repetitive regeneration of hBLM can be performed up to 4 times with no major loss of the electrochemical properties. Also, we showed that the electric barrier function of hBLMs is disrupted by phospholipase A(2) (PLA2) - an enzyme, which hydrolyzes the fatty acid bonds at sn2 position in membrane phospholipids. Such effect may be used to design biosensors sensitive to both concentration and activity of the membrane damaging proteins, and possibly other agents.

Layer Formation and Investigation by Electrochemical and Quartz Microscopic Methods. Assoc. Prof. Dr. D. Plaušinatis.

Study focused on measurement of lanthanides in surface water (SW) and ground water (GW) samples from the Chernobyl Exclusion Zone. Results showed that the total lanthanide concentration in SW ranges from 500 to 1100 ng L-1 and is about 10 times lower than the GW concentration. The normalized patterns of lanthanide concentrations increase from lighter elements to heavier lanthanides. Concurrently, concentration anomalies of Ce, Eu, and Er are visible. The Er anomaly is the most noticeable and exceeds the theoretical calculation by about 13 times. The Ce and Eu anomalies are likely related to the variety of oxidation states of these elements. Meanwhile, the cause of the Er anomaly is not completely clear, but is likely related to the Chernobyl Nuclear Power Plant accident, since increased concentrations correlate with the distribution of contamination in the zone. Cs-137 activity measurements partially confirm this hypothesis. Simultaneously, there is a relationship between the positive Er anomaly and increase in U-235 concentrations. However, there is no reliable information in the literature that indicates that Er was used in the Chernobyl Nuclear Power Plant before the reactor accident.

Ionogenic Brush Polymers for Nanotechnology. Prof. R. Makuška.

Diblock brush copolymers synthesized by chain extension had higher dispersity compared to that of the homopolymers, and the copolymers with the longest PEO chains contained a fraction of the “died” chains. Synthesis of diblock brush copolymers by “one pot” RAFT polymerization was preferential over polymerization with isolation of the first block. Novel highly branched cationic polymers containing different amount of disulfide linkages were less cytotoxic compared with PHPI, and they were able to disintegrate and release DNA following the treatment with reducing agent DTT.

Use of Satellite Information for the Assessment of Hydroclimatic Resources. Prof. E. Rimkus.

The main research task is to develop new algorithms and methods to determine snow water equivalent, freshwater ice parameters and soil moisture from Sentinel-1 SAR. The ground based freshwater ice, snow cover and soil moisture observations have declined in number over last decades. Satellite remote sensing with large spatial coverage and frequent revisit time might be the most robust replacement of in situ measurements of snow and freshwater ice cover parameters. Up to date satellite information provides new assessment capabilities of environment condition.

Study of the Natural and Social Effects of Climate Change in the Baltic Sea Region. Prof. A. Bukantis.

The purpose of the present project was to investigate the potential impact of climate change on nutrient (total nitrogen and total phosphorus) loads from four large-scale river catchments in Lithuania. The impact on nitrogen and phosphorus was chosen because they are the main nutrients responsible for the eutrophication of surface waters including the Baltic Sea. The results indicate a decreasing trend in the stream flow and nutrient loads in most of the studied Lithuanian rivers under the projected climate change.

Investigations of the Effects of Environmental Change on Inland Water Systems. Prof. G. Valiuškevičius.

In 2018, the long-term impact of climate change on the hydrological regime of Lithuanian inland water objects was analyzed. The detailed analysis of the floods in the lower reaches and the delta of the Nemunas River was performed. The study examined the conditions which predetermine the formation of dangerous floods and the probability of their recurrence in the 20th century. Fluctuations of the water table in the Čepkeliai bog have been studied as an additional indicator of the long-term climate change impact.

The main results obtained during 2018 have extended the knowledge about the lithological anomalies, as well impact of natural and anthropogenic factors on the distribution of sands of different grain size along the southeastern Baltic Sea three spits on the sandy beaches. The integrated approach of dune investigations offered an estimate of the rates of sand accumulation and key phases of aeolian dynamics during both stormy and calm periods, as well as helped extend the record of dune evolution to mid-Holocene.

International Research Projects

COST activity: A European Network for a Harmonised Monitoring of Snow for the Benefit of Climate Change Scenarios, Hydrology and Numerical Weather Prediction. E. Rimkus. 2014–2018.

European research teams have developed different snow measurement practices, instrumentation, algorithms and data assimilation techniques customised to their purposes. However, they lack harmonised approaches, validation and methodologies. The Action co-ordinate efforts to address these issues, through establishing harmonized monitoring practices, enhancing the use of observations by promoting new observing strategies, bringing together different communities, facilitating data transfer, upgrading and enlarging knowledge through networking, exchange and training, and linking them to activities in international agencies and global networks.

COST activity: Natural Flood Retention on Private Land. G. Stankūnavičius. 2017–2020.

Climate change increases the frequency and intensity of future flood events, leading to higher costs of flood damages and increasing the public demand for protective measures. Traditional flood protection measures, mainly based on grey infrastructure (i.e. dikes, dams, etc.), are not sufficient to cope with dynamic flood risk alone. Nature-based solutions such as Natural Water Retention Measures (NWRM) are promising options to mitigate flood risks as a complement to grey infrastructure. These types of measures not only serve to reduce risk, they also provide additional ecosystem services including increased biodiversity and recreation opportunities. However, a common characteristic of green infrastructure measures is that they often claim more land than traditional methods.
