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

Although the efficiency record of perovskite solar cells is already above 25%, long-term stability is a key challenge for their commercialization. A strategy to stabilize perovskite films and solar cells against photodegradation by using an organic cation, S-methylthiouronium (SMT) was proposed. Replacing 20% of methylammonium (MA) by S-methylthiouronium in mixed leadhalide perovskites enables a fivefold increase in the stability of perovskite solar cells against degradation in ambient air under full solar irradiation. This partial exchange of cations also contributes to the improvement in film formation quality. The investigation results, including high-performance liquid chromatography measurements, suggest that the material stability improvement is related to the structural rather than chemical stabilization of the perovskite lattice.

The colorimetric sensors for reducing sugars based on a redox reaction between AuCl₄- ions and fructose, glucose, lactose, or mannose was developed and characterized. Different reducing sugars exhibited distinct reaction rates for gold nanoparticles formation, with the rate decreasing in the order fructose > glucose > lactose > mannose. The colorimetric sensor was evaluated for use in real samples of beverages, milk, and saliva.
An electrochemical immunosensor signal amplification strategies using metal nanoparticles (MNPs) and quantum dots (Qdots) as tags were overviewed, focusing on recent developments in the ultrasensitive detection of biomarkers. MNPs and Qdots can be used separately or in combination with other nanostructures, while performing the function of nanocarriers, electroactive labels, or catalysts.
Electrochemical glucose biosensor based on electrochemically on a graphite rod electrode deposited dendritic gold nanostructures was successfully developed. This glucose biosensor showed a quick response, a high saturation current, appropriate linear range, good repeatability, low limit of detection and good stability. Additionally, the Prussian blue, poly(pyrrole-2-carboxylic acid), and glucose oxidase biocomposite modified graphite rod electrode as a potential biocathode for single enzyme biofuel cell fuelled by glucose was developed and characterized.

Deep Eutectic Solvents: Synthesis, Investigation and Application. Prof. Dr Vida Vi膷ka膷kait臈, Assist. Dr Vilius Po拧kus.

Fifteen low volatility deep eutectis solvents were prepared using microwave heating. The behaviour of the solvents at elevated temperatures was examined and it was determined that at 80oC temperature all the eutectic solvents tested except choline chloride-imidazole were stable with no peaks in their headspace chromatograms.
For hexanal determination in fat-rich food by coupling microwave assisted extraction and static headspace gas chromatography, choline chloride-glucose-water showed the best extraction efficiency. Microwave assisted extraction and headspace gas chromatographic conditions for hexanal determination were optimized.
For 尾-caryophyllene determination in different fat-rich matrices solid-phase microextractions has been applied. Choline chloride-urea was determined to be the best deep eutectic solvent for samples dispersion and preparation of calibration solutions.
Under optimized conditions analytical characteristics of the suggested techniques have been determined. The developed techniques were applied to determine hexanal in fat-rich food and to determine 尾-caryophyllene in cannabis oil and in cannabis seeds.

RESEARCH PROJECTS CARRIED OUT IN 2021

Development and Investigation of Functional Heteroaromatic Materials. Prof. S. Tumkevi膷ius, Assoc. Prof. Dr J. Dodonova-Vaitk奴nien臈, PhD student I. Fiodorova. 2014鈥�2021.

Novel carbazole-pyrimidine and carbazole-pyrazine conjugates as TADF emitters for OLED application were designed and synthesized by using transition metal catalyzed cross-coupling reactions. Influence of electronic and steric peculiarities of substituents in a diazine moieties and their substitution patern on electronic, photophysical characteristics was investigated. The findings are important for further optimization of TADF compounds with diverse molecular structures.

Synthesis of Functionalized Propargylic Substrates and their Application in Construction of Heterocyclic Structures. Dr I. Karpavi膷ien臈, Dr. R. Buk拧naitien臈, I. Misi奴nait臈.

Our research focuses on the electrophile-initiated cyclization reactions of propargylic substrates combined with imidazole moiety. The investigation includes the evaluation of influence on the reaction outcome of substituents on the starting material and reaction conditions as well as the scope and limits of chosen substrates in use for the formation of new condensed imidazole systems. As a result, unprecedented oxidative N-N dimerization of imidazole derivatives has been discovered.

Synthesis of 4,6-Disubstituted Benzene-1,3-Dioles as Potential Hsp90 (Heat Shock Protein) Inhibitors. Assoc. Prof. A. Bruk拧tus, P. Kaziukonyt臈.

Heat shock protein 90 (Hsp90) belongs to the family of chaperones. Recent data showed that the amount of this chaperone significantly increases in cancerous cells, therefore it was concluded that Hsp90 is necessary for the growth of malignant cells. Treatment for these types of diseases is expected to be found by inhibiting the protein. In earlier works we demonstrated, that compounds carrying 2-alkylbenzene-1,5-diol moiety is crucial for the inhibition of Hsp90. Based on these results, our ongoing research is concentrated on the synthesis of new 4-(1-aryl-1H-imidazol-5-yl)-6-alkylbenzene-1,3-dioles as possible inhibitors of Hsp90 chaperone.

Nucleic Acids Tagging Technologies. Prof. V. Masevi膷ius, Dr G. Petraityt臈, M. Malik臈nas.

Synthesis and enhanced functionalities of AdoMet analogues for nucleic acids labeling biological methylation is a methyl group transfer from S-adenosyl-L-methionine (AdoMet) onto N-, C-, O- or S-nucleophiles in DNA, RNA, proteins or small biomolecules. The reaction is catalyzed by enzymes called AdoMet-dependent methyltransferases (MTases).
To expand the practical utility of this important enzymatic reaction, cofactors containing sulfonium-bound side-chains with various functional or signal groups instead of methyl group were synthesized. These AdoMet analogues serve as cofactors for a variety of wild-type and mutant DNA, RNA or protein MTases enabling covalent attachment of these chains to their target sites in DNA, RNA or proteins (the approach named methyltransferase-directed Transfer of Activated Groups, mTAG).
Compounds containing sulfonium-bound propargyl moiety has proved to be efficient alkylating agents for labeling of DNA and RNA alike. While DNA MTases even engineered ones like E119H M.HhaI efficiently uses AdoMet analogues with only medium size side-chains, some RNA MTazes, e.g. Hen1 can use as cofactors even large signal groups (Biotin, Cy3) possessing AdoMet analogues.

Synthesis of Polycyclic Scaffolds Fused with Heteroaromatic Metal Coordinating Units. Prof. A. 沤ilinskas, Dr S. Vi拧niakova.

Vegetables as biocatalysts were screened for the stereoselective biotransformation of racemic bicyclo[3.3.1]nonane-2,6-diol diacetate. The best results were obtained using the roots of carrot (Daucus carota) and parsnip (Pastinaca saliva) and the rootstocks of ginger (Zingiber officinale). During the biotransformation of racemic bicyclo[3.3.1]nonane-2,6-diol diacetate the enzymatic hydrolysis took place. Under different reaction conditions, i.e. the reaction temperature and time, and using different plant material as biocatalyst, (1R,2R,5R,6R)-(+)-bicyclo[3.3.1]nonane-2,6-diol monoacetate or (1S,2S,5S,6S)-(-)-bicyclo[3.3.1]nonane-2,6-diol monoacetate were obtained as reaction products. (-)- Enantiomer with the optical purity of 29.3% was obtained at 25 degrees C using parsnip as biocatalyst for 2 days and (+)- enantiomer with the optical purity of 44.1% was obtained at 30 degrees C using carrot for 3 days.

Novel phenoxazine-pyrimidine conjugates of type D-s-A-s-D, where D and A are electron donor and acceptor, respectively, s - spacer, were designed and their optical properties investigated. An optimum molecular geometry was revealed with a balanced ratio between the singlet鈭抰riplet energy splittings and corresponding coupling strengths, showing the submicrosecond solid-state TADF lifetime and high emission yield. The optimized TADF compounds were employed in OLED devices as emitters with tunable emission color from sky-blue to green. Outstanding peak EQE values from 26% to nearly 30% were obtained with minimized EQE roll-off.
A series of purines, substituted at C2 and C6 positions with electron acceptor and donor groups of different strengths were developed, and their photophysical and complex forming properties with metal ions studied. A new concept of a ratiometric chemical fluorescence sensor for metal ions involving the photoinduced electron transfer (PET) between branches of different ligands as a mechanism of fluorescence modulation has been proposed.

We developed a new red-emitting, viscosity-sensitive, BODIPY fluorophore BP-PH-2M-NO₂ that is suitable for reliable intracellular viscosity imaging of lipid droplets in MCF-7 breast cancer cells. The design of BP-PH-2M-NO₂ was aided by DFT calculations that allowed a successful prediction of the viscosity sensitivity of fluorophores before synthesis. New red viscosity probe possesses monoexponential fluorescence decay that makes it attractive for lifetime-based viscosity imaging.

Synthesis and Study of Brush Polymers for Surface Modification. Prof. Dr R. Maku拧ka.

Cationic gradient brush copolymers carrying PEO side chains and catechol moieties were synthesized by RAFT copolymerisation of PEO macromonomer and DMAEMA with succeeding quaternisation, and the copolymers were characterised by SEC, NMR, FTIR and Raman spectroscopy. Catechol-containing diblock brush copolymers were synthesized, and wear resistance of such copolymer layers in water was evaluated and compared with that of statistical copolymers with similar composition. The presence of catechol groups in the structure of the neutral diblock copolymers gave the highest underwater wear resistance of the adsorbed layers.

Landscape Anthropogenization and Justification of the Need for Ecosystem Services. Prof. D. Veteikis. 2019鈥�2024.

The aim of the project is to assess the extent, direction and impact of landscape change on the quality and need for ecosystem services. There are several parallel studies carried on within the scope of the project. One is to evaluate the influence of landscape instability caused by anthropogenic disturbances on the quality of ecosystem services on a national level. The classification of the landscapes under anthropogenic impact in local level is being created in order to get the knowledge on landscape variety in the country. The trajectories of landscape structure change having started from the middle of the 19th century are being under evaluation using the historical maps.

Changes in Soil Properties and Their Impact on Landscape Structure and Rational Use. Assoc. Prof. J. Volungevi膷ius. 2019鈥�2024.

The aim of the research is to determine the tendencies of changes in Lithuanian soil properties under the conditions of their different use. The identification of trends is relevant to assess the sustainability of the use of soil resources and to predict changes in their quality. This is relevant when substantiating agro-ecosystem spatial planning measures and recommendations for use intensity. It is important to study not only the soils of agricultural areas, but also the soils in protected areas in order to compare how the properties of the soil change with its use. During the study, changes in soil profile morphology, chemical, physical properties and moisture regime were analysed. Intensive use of soil in agriculture has been found to cause loss of soil organic carbon, deterioration of its structure and disruption of the hydrothermal regime. Researchers also cooperated with the Nature Research Centre while investigating nearshore sandbars.

The Lower Paleozoic Carbonate Systems of the Baltic Sedimentary Basin. Assoc. Prof. D. Kaminskas. 2019鈥�2024.

The main goal of the project is to study the peculiarities of carbonate sedimentation and diagenesis of the Baltic Silurian Basin. The carbonate analysis was applied for 399 samples. The carbonate content (calcite and dolomite) was determined for bulk samples. It was suggested that the increase in carbonate content, and also increase in variability of carbonate content, as well as decrease in LOI and magnetic susceptibility is associated with the Klonk excursion. The variation of carbonate content vs terrigenous material was established in Milaiciai 103 well. The lithological along with the carbonate analysis of probable relative depth changes revealed a long term shallowing trend, which was related to the final phases of the development of the Silurian Baltic Basin.

Mesoproterozoic Igneous and Ore Complexes in the Crystalline Base of Lithuania and Surrounding Regions. Assoc Prof. Gra啪ina Skridlait臈. 2019鈥�2024.

The main goal was to identify and link mesoproterozoic igneous, metamorphic and ore geological events in the crystalline bedrock of eastern and southern Lithuania. The origin and age of granitoids crossing the rocks of the Var臈na iron ore deposit were studied. The age of two granitoids from D9 and 987 wells was determined by secondary ion mass spectrometry (SIMS) at NORDSIM Laboratory in Stockholm. Both circular granite (D9) and walled granite (987) formed about 1.50 billion years ago. Dated zircons have been depleted by hydrothermal solutions and radioactive decay, making the dating of such zircons quite complex. An article has been prepared with a proposal to solve this problem.

Palaeogeography of the Quaternary Period. Prof. P. 艩ink奴nas. 2019鈥�2021.

The main research task is to determine the development of palaeogeographical environment during the Late Pleistocene - Early Holocene based on the study of deposit sequences. The research group studied sedimentary records in the south eastern Baltic Sea region to reconstruct the climatic fluctuations and the abiotic responses to them during the Lateglacial and Early Holocene. The results obtained contribute to a deeper understanding of how the local sediment sequences reveal the global climatic trends.

Silurian is one of the shortest and most dynamic periods in the history of the Earth. Although, this period was one of the shortest, it witnessed several large scale paleobiological, paleoclimatic and global carbon cycle perturbations. It can be argued that during the Silurian period the first modern marine ecosystems appeared with vertebrates as top predators. During this time interval vegetation started to actively spread on land. With the spread of terrestrial vegetation intensified weathering of rocks and the sequestration of the carbon dioxide in the earth's crust, this led to the global atmospheric compositional changes that have had an impact on the global climate. Three glacial episodes are recognised during the early Silurian. The direct evidence of glaciations in the Late Silurian were not recognized in the geological record. Though, sudden and cyclical sea level falls and the fluctuations in the stable carbon and oxygen isotopes point to their possible existence.

Evolutionary history of life on Earth is marked by a series of volatile environmentally mediated major transitions in individuality, modes of information transfer, and most importantly rates of macroevolution which determine innovation potential of the biota. Phanerozoic eon is the most recent half a billion years, which is characterized by the origination, and expansion of all modern complex multicellular plant and animal taxa. This largest scale evolution of the biota was characterized by multiple episodes of mass extinctions and evolutionary radiations that followed them. There is growing body of evidence that shows mass extinction episodes as the major transitions in the modes of macroevolution and diversity dynamics. Nevertheless the spatial impact of macroevolution on the systemic changes in origination and extinction rates and their mutual coherence is almost completely unknown at the global scale.

Polish-Lithuanian collaboration group (DAINA) project Ichnological and Sedimentological Evidence of Late Glacial and Holocene Environmental Changes in the Eastern Part of the European Sand Belt. Prof. Andrej Spiridonov - principal investigator, members: Prof. Petras 艩ink奴nas, Dr Eugenija Rudnickait臈 and Liudas Daumantas. 2018鈥�2020.

The planned research is based on the field work. Special attention will be paid to humic horizons, including palaeosols, where the most abundant trace fossils and bioturbation structures are expected. Such studies will be accompanied by parallel sedimentological and stratigraphical analyses, with an application of optically stimulated luminescence and radiocarbon datings, georadar and statistical methods. This will allow presentation of the dynamics of the aeolian sediments in space and time and to integrate them with results from the ichnological research.

Use of Satellite Information for the Assessment of Hydroclimatic Resources. Prof. E. Rimkus. 2019鈥�2024.

The main research task is to develop new algorithms and methods to determine snow water equivalent, melting snow water 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. This project aims to explain the uncertainties emanating from atmospheric correction (AC) product selection and how they influence chlorophyll 伪 concentration retrieval in lakes of Lithuania.

Study of the Natural and Social Effects of Climate Change in the Baltic Sea Region. Prof. A. Bukantis. 2019鈥�2024.

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.
Also accuracy of air temperature and precipitation monthly and seasonal forecasts generated for the territory of Lithuania using the NOAA's Climate Forecast System was investigated.

Sea Coast Litho-Morpholgy Dynamic and Modeling. Assoc. Prof. D. Pupienis. 2019鈥�2020.

Coastal geodynamic processes lead to beach sediment erosion or accumulation. The coast鈥檚 dynamic tendencies determine the changes in the volume of beach sediments; grain size; mineralogical; and geochemical composition of sediments. In addition to lithological and mineralogical analysis of sediments, geochemical analysis can provide valuable information about the local and regional patterns of sediment transport, distribution, provenance, and coasts鈥� conditions. The research aims to assess trace metals鈥� temporal and spatial distribution determined in the sandy beach sediments along the south-eastern Baltic Sea coast (Lithuania) during 2011鈥�2018.

Use of SENTINEL-1 SAR Poliarimetry to Determine Snow and Ice Cover Characteristics. Prof. E. Rimkus. 2019鈥�2021.

The aim of the project is to develop new algorithms for freshwater ice detection and snow water equivalent determination using ESA Sentinel-1 SAR high temporal and spatial resolution polarimetry. Simulation of the microwave scattering in the snowpack using SMRT snowpack model and the deep learning algorithms to relate the SAR backscattering signal to snow cover characteristics have been used. Project team developed lake and river ice detection algorithms based on the threshold values of SAR single polarization products and classify ice type using H Alpha Wishart and Cloude-Potter dual polarization decomposition methods.

The tasks of activity are: to develop a common understanding of Compound Events; to create awareness in climate and climate impact communities about the inherent modelling challenges associated with Compound Events; to provide complementary training for Early Career Investigators (ECIs) in dynamical modelling, multivariate statistics, and extremes, all inherently relevant for studying Compound Events; to improve stakeholders' understanding of Compound Events and limitations to modelling these, enabling them to plan more targeted; to improve stakeholders鈥� awareness of the importance to document physical and/or monetary impacts of Compound Events to foster scientific progress.

COST activity (CA19109). European Network for Mediterranean Cyclones in Weather and Climate. Dr G. Stank奴navi膷ius. 2020鈥�2024.

Cyclones are the main weather modulators in the Mediterranean region and constitute a major environmental risk, often producing windstorms and heavy rainfall. Moreover, cyclones play a key role in the regional climate variability by controlling the oceanic circulation and regional water cycle, and by mobilizing and transporting large amounts of dust from North Africa.
Efficient networking between stakeholders, operational weather forecasters and researchers is timely and essential to address both challenges of research coordination and operational implementation of scientific results into weather and climate services. This Action coordinates the activities of researchers in meteorology and climatology and scientists from weather/climate services with the main aims to provide a deeper understanding of Mediterranean cyclones and to improve significantly the European capacity to predict their environmental and climate impacts. In this context, the network will identify, and involve in the network, relevant stakeholders with different backgrounds (e.g. civil protection, re-insurance companies) and co-develop cyclone prediction products tailored to their needs.
