Research Topic Summary.
Efficient, energy-saving optoelectronic devices, such as solar cells (SC), light emitting diodes and products containing these technologies are rapidly entering the market and are integrated into the future appliances and machines. One of the main sources of renewable energy is sunlight. Every hour Earth receives 1.78×1014kWh of solar irradiation, while total annual energy consumption by the people of Earth is 1×1014kWh. Perfecting the means of solar energy harvesting would allow us to substitute all other sources of energy used today. Total capacity of the solar power plants in Japan in 2017 was 49 GW, Germany – 42 GW, China – 131 GW [NREL 2017 Renewable Energy Data Book, March 2019]. Currently cost of the solar cell generated electricity is around 0.2$/W [Bloomberg New Energy Finance], down significantly from 2$/W from just few years ago. At the moment crystalline silicon accounts for the majority solar cells produced currently (~95%), however this is an energy intensive and relatively expensive technology requiring large capital investment.

Creation and Investigation of Lightweight Wooden Building Constructions

doc. dr. Darius ALBREKTAS |
state non-funded |
Research Topic Summary.
Wooden constructions are widely used in building and other industries. The popularity of wood is determined by its relatively simple machining, availability, low density, good other physical and mechanical properties. In order to change the properties of these structures in the desired direction, wood in them is composed in various ways with other materials - metals, glass, textiles, etc. The negative qualities of wooden constructions could be characterized by a large distribution of mechanical and physical properties of wood, and low resistance to environmental influences. In addition, many of these structures are massive, so their production requires large amounts of materials, energy consumption. The aim of the work is to design lightweight, characterized by good mechanical properties, low material inputs and weather resistant, environmentally friendly timber structural elements suitable for the production of building constructions. Tasks: 1 - to evaluate the influence of individual elements of wood (dimensions, shapes, etc.) on the mechanical properties of the entire structural element; 2 - to evaluate the influence of other materials, their quantity on the mechanical properties of a wooden structural element (composite); 3 - depending on the exploitation conditions of the elements, to select the optimal ways and materials for connecting the individual components of the construction; 4 - by composing wood with other materials, to create structural elements with appropriate (depending on the purpose) properties. After analyzing the results of the research, made the construction elements from wood and other materials with the required properties, using the minimum amount of wood for their production. To provide recommendations for designers, manufacturers of wooden building constructions.

doc. dr. Jurgita DOMSKIENĖ |
state non-funded |
Research Topic Summary.
To address the problem of overconsumption of energy and natural resources, relevant research focused on high-value-added products with exceptional functional properties and recycling potential. Modern challenges of textile science are related to interdisciplinary research, integrating traditional materials science with the application of biotechnology, principles of microelectronics engineering and so on. Research is concerned with materials of different properties that are integrated into systems to produce adaptive functional products. The goal of the research is to develop functional flexible systems based on textiles with good wearable properties and recycling possibilities.

Recycled polymer raw materials consumption for the new functional materials for particular purpose

v.m.d. dr. Daiva MILAŠIENĖ |
state non-funded |
Research Topic Summary.
Nowadays attention to the new technologies of waste control and recycling highly increases. However, in case of rapidly growing society urbanization and still insufficient intensity of the use of secondary raw materials, the amount of unprocessed waste (tires, textiles, various plastics, etc.) is increasing in the world. Attitude is also changing: it is not the waste that disfigures environment but a valuable secondary raw material. Their processing techniques and usage expansion is relevant task in both of nowadays academic and business fields. A number of processing problems may be faced during the recycling process of polymeric waste: materials polluted with inappropriate elements, unsuitable for further products manufacturing; the influence of ingredients for specific properties of previous product to the technological properties of new polymeric compound; inequality of waste chemical composition, etc. Secondary raw materials often already are the mixture of various additives so their usage for the new polymers compounds radically changes both of the properties of new product and the parameters of technological processes. During the investigations it will be quested new opportunities to apply modern technological solutions to use polymeric waste which are accumulated in Lithuania for the new functional materials. Objectives: 1. To investigate influence of technological parameters to the secondary raw materials composition and properties. 2. To investigate dependence between properties of new polymeric compounds with secondary raw materials and its composition, proportion, pollution. 3. To investigate properties changes of compositions with secondary raw materials according to secondary raw materials proportion. 4. To develop prototypes of new functional materials.

prof. habil. dr. Sigitas TAMULEVIČIUS |
state non-funded |
Research Topic Summary.
Optically active substrates such as particularly arranged affays of plasmonic nanoparticles have great potential for biosensor applications. Preparation methods include top-down and bottom up approaches including self-assembly or lithographic methods. A special case, which benefits of both approaches, is use of selforganrzedtemplates for nanostructure deposition. In this project capillary force assisted particle assembly will be produced and studied for applications including Surface Enhanced Raman Spectroscopy (SERS), elastic scattering and photoluminescence for biosensing. The project will aim at the developing of effective nanostructured templates, production of regular noble metal nanoparticle affays, design and synthesis of optical sensor, as well as construction of SERS, luminescence, absorption and elastic scattering based biosensor for diagnosis of ocular surface and systemic diseases. for further information please contact the supervisor of the topic.

Synthesis and application of electroactive materials for organic light emitting diodes

prof. dr. Saulius GRIGALEVIČIUS |
state non-funded |
Research Topic Summary.
Recent advances in organic optoelectronics, particularly in efficient organic light-emitting devices (OLED), have called for new electro-active organic materials as well as for new device technologies. Small OLED-based displays already generate hundreds of millions of dollars. Larger OLED displays will penetrate the television market in the not-too-distant future. Nowadays white displays play important role in lightening. Further advances of these devices substantially rely on development and studying of high-performance organic charge-transport and host materials, theoretical understanding of charge and energy transport in the organic systems and their well-balanced application in phosphorescent and thermally activated delayed fluorescence (TADF) devices. The aim of this project is to synthesize several groups of polymeric, dendrimeric or branched wide band gap derivatives, which would serve as thermally stable host materials or TADF emitters for organic light emitting diodes. In order to optimize efficiencies of the devices, several groups of new hole transporting materials, which are used as additional charge injecting/ transporting layers, will be also synthesized in the frame of this project.
