The influence of iminium ions鈥� structures on their stability by comparing six nitrogen-containing cyclic compounds as derivatization reagents for tandem mass spectrometric analysis of amino group-containing analyte was studied. Piperidine, 2,6-dimethylpiperidine, 1-methylpiperazine, morpholine, pyrrolidine and 1-cyanomethyl-3-methylimidazolium were used for the synthesis of corresponding carboxylic acids which were further used for derivatization of tryptamine. Morpholine moiety was shown being the most promising iminium ion source among tested compounds.

Gas Chromatographic Analysis of Volatile Food Constituents. Prof. V. Vi膷ka膷kait臈, Assist. V. Po拧kus.

Direct and headspace gas chromatographic analysis was compared for the determination of lactic, oxalic, succinic, malic and citric acids. Prior to analysis carboxylic acids were derivatized using BSTFA as a silylation reagent. Three solvents 鈥� acetone, diethyl ether and dimethylformamide 鈥� were tested as a derivatization medium and dimethylformamide was considered as the best. Derivatization conditions were optimized and analytical characteristics of direct gas chromatographic determination of the analytes in the solutions were determined.

Synthesis, Design and Applications of Functional Supramolecular Systems. Prof. E. Orentas.

The cyclic supramolecular coordination constructs were synthesized via metal-directed self-assembly from cis-protected Pd(II) precursor and chiral and racemic C2 symmetric V-shaped bicyclo[3.3.1]nonane-based ligands incorporating pyridyl groups. In the complexes, these ligands act as bridges to connect together metal centers resulting in dinuclear and tetranuclear assemblies capable of further hierarchical aggregation on surfaces as well as in solution. Supramolecular structures obtained were characterized by mass spectrometry and NMR spectroscopy.

Alkynes versatile reactivity to nucleophiles and electrophiles gives broad aproach to consturction of wide range of functionalized materials and heterocyclic systems. In this year we showed that heteroarylmethanethiols and their analogues heteroarylmethyl carbamimidothioates are useful nucleophiles synthesizing various 3,5-diaryl-2-heteroarylthiophenes via Fiesselmann type reaction. These compounds exhibited photoluminescence with quantum yields up to 83%. An evidence of twisted intramolecular charge transfer and singlet emissive states have been demonstrated.

Nucleic Acids Tagging Technologies. Prof. V. Masevi膷ius.

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.

The conformational disorder in solid films of phenothiazine鈥損yrimidine TADF molecules and its relation to emission properties were investigated. Compounds were designed to have different lability of the molecular structure and different reverse intersystem crossing (rISC) rate. It has been shown that the emission energy of TADF molecules in solid films may depend not only on the conjugation length, but also on some unexpected parameters, such as the rISC rate or molecular core rigidity.

Spontaneous oxidation of Prussian white (PW), which is completely reduced form of Prussian blue (PB), has been investigated at ambient conditions and stable form of PW-PB as an intermediate oxidation state was identified and investigated. Two types of optical slides were manufactured by modifying indium tin oxide (ITO) coated glass electrode (glass/ITO) (i) with PW layer (glass/ITO/PW optical slide) and (ii) with PW-PB layer (glass/ITO/PW-PB optical slide). Modification of the developed slides with glucose oxidase showed that glass/ITO/PW/GOx slide acted as glucose biosensor.

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

A nanotribological scanning probe method was utilized to evaluate the wear resistance of the layers of statistical copolymers containing medium-length poly(ethylene oxide) side chains and randomly distributed dopamine groups. New method to study kinetics of homo- and copolymerization of vinyl monomers based on SEC was developed. The developed method is especially efficient in the case of SEC with triple detection since it allows estimation of polymerization kinetics in parallel to the development of molecular weight and dispersity of the polymers.

National Research Projects

Ecosystem Construction and Collapse in the Silurian 鈥� Survival of Biodiversity in the Extreme Climate (one of 4 project implementers). Prof. S. Radzevi膷ius. 2019鈥�2022.

Within the framework of the project it is planned to cover the Silurian period and proximate time epochs. Dynamics of marine ecosystem in relation to the global climate forcing will be analysed using advanced statistical techniques of Deep Learning, Random Forests, and forward mathematical modelling. Additionally, we will test the influence of the Milankovitch cycles (changes in the astronomical Earth鈥檚 orbit鈥檚 parameters) on observed paleoecological patterns and episodic perturbations of oceanic conditions and the carbon cycle. The abundance of geobiological events during the analysed period of time will enable us to distinguish between idiosyncratic (peculiar to the local conditions) and general patterns of ecosystems responses to the large scale physical perturbations, which in turn will help us to accurately and reliably predict possible future changes in the marine ecosystem.

International Research Projects

Grant for 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. Dr. A. Spiridonov. 2018-2020.

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.

Within the 91桃色 and IAEA Research Program F33022 work plan one of the aims for Baltic region was to prepare a new approach of deep aquifer investigation that will be focused on using a wide complex of environmental isotopes, noble gases, groundwater chemistry and hydraulic data via coupled analysis of groundwater flow numerical models. Revealed that the highest accumulation rates of helium in BAB deep aquifers are located near Baltic Sea coast and islands, lowland areas of lakes or rivers where groundwater flow is upward discharged, properly from above tightly protected from meteoric water downward leakage and transected by wide low amplitude fault system networks which are able to reduce or interrupt regional lateral flow path. Radiogenic helium flux from crystalline basement at local level sites have good conditions for accumulation below regional confining aquitard layers system for all beneath placed reservoir traps depending on hydraulic features of aquifers. Due to its atmospheric origin 81Kr pathway should be similar to the modelled particle travel trajectory in the strongly confined aquifer system but it鈥檚 not so far same order, because the difference between the 81Kr age and particle travel time is significant. Radiokrypton and 4-helium ages differs 2-3 times, because helium generation and distribution pathway in multi-layered aquifer system over time is uncertain caused by changes of ice sheet loading through Pleistocene. Plausible absence of fault fractures zones in numerical model should be reflected that zone geometry and by certain aperture or these barrier parameters for layers.

Use of Satellite Information for the Assessment of Hydroclimatic Resources. Prof. E. Rimkus. 2019鈥�2020.

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. 2019鈥�2020.

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. Valiu拧kevi膷ius. 2019鈥�2020.

In 2019, the long-term impact of climate change on the hydrological regime of Lithuanian inland water objects was analysed. 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 膶epkeliai bog have been studied as an additional indicator of the long-term climate change impact.

Sea Coast Litho-Morphology Dynamic and Modelling. Assoc. Prof. D. Pupienis. 2019鈥�2020.

The main results obtained during 2019 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 south-eastern 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.

Use of SENTINEL-1 SAR Poliarimetry to Determine Snow and Ice Cover Characteristics. Prof. E. Rimkus. 2019鈥�2020.

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 will be used. Project team will develop 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 algorithms and methods will be developed and validated using in situ measurements of snow and ice cover parameters and auxiliary data will be collected from all available sources.

COST activity: Natural Flood Retention on Private Land. Dr. G. Stank奴navi膷ius. 2017鈥�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.
