Modeling and investigation of mechanical properties of wooden constructions
|
doc. dr. Darius ALBREKTAS |
state-funded |
Research Topic Summary.
Wooden constructions are widely used in construction and other industries. The popularity of wood is determined by its relatively simple machining, availability, good 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. The properties of the structures are also determined by the various holes required for mounting or communications. In addition, many of these structures are massive, which involves large amounts of materials, energy consumption. In the construction, each element determines its certain property. Using a unique methodology, the mechanical properties of individual structural elements can be determined. Later, by selecting wood with appropriate properties (it is known that the mechanical properties of the same wood species can differ up to 2 times or more in the same fiber direction), composing it accordingly or with other materials, changing joining methods, material ratio or orientation in structure, it is possible to obtain desired (sometimes unique) properties. In the production of constructions from wood and wood materials, often sockets, grooves, holes, which are necessary for fastening details to each other, for communications. These elements often degrade the properties of the whole structure. By optimizing their location and orientation in the construction, the impact of these elements can be reduced.

Development of functional textile systems and investigation of their exploitation
|
doc. dr. Jurgita DOMSKIENĖ |
state-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. Applying technology of stitching, adhesive bonding or melting, to ensure durable joints of material layers, however, special functional properties tend to change during intensive exploitation of garment. Functional systems of textile and polymeric material are being developed to increase the reliability of protective, sports, medical clothing, human safety and comfort. Research tasks: - Investigate possibilities to compose reliable functional systems combining of textile materials of different nature and weave type with electrically conductive materials (fabrics, threads); - Investigate the reliability of the system during exploitation and intensive garment care, and provide recommendations for improving the reliability and durability of the system; - Define environmental aspects of joint systems and to analyse recycling options, provide guidance on the choice of system components and bonding technologies to enhance assembly and recycling capabilities.

Laser induced functional nanostructures
|
prof. dr. Tomas TAMULEVIČIUS |
state-funded |
Research Topic Summary.
Quite recently unprecedented micro and nanostructuring capabilities of the materials were unleashed using ultra-short pulse laser carrying GW order peak powers. Despite the extensive studies in the past decade, the formation of laser-induced periodical surface structures (LIPS) on materials is not fully understood and the generally accepted models explaining the process are mainly phenomenological. LIPSS is attractive for a manifold of applications imposing new functionalities fur regular materials surfaces including wettability control, biocompatibility, anti-counterfeiting applications, control of light reflectance, and energy harvesting. This work aims to extend the understanding of the intense laser pulse interaction with transparent and opaque materials and provide novel applications for LIPSS. Tasks: i) to select ultra-short pulsed laser processing parameter aiming for desired configuration self-organized periodic surface structures; (ii) fully describe the properties of the formed nanostructures; (iii) investigate the aging effects of their properties and the influence of the environment of the rate of aging; (iv) propose new applications of LIPSS within antireflective surfaces and energy harvesters. It is anticipated that the carried-out research will contribute to the deeper understanding of the photonics society regarding the LIPSS formation mechanisms in different materials and these nanostructures will find new areas of application, e.g., for water for self-sustained water purification under natural sunlight.

Synthesis of noble metal nanoparticles and application for surface enhanced Raman scattering sensors
|
doc. dr. Asta TAMULEVIČIENĖ |
state-funded |
Research Topic Summary.
In recent years, the development of nanotechnologies and understanding of the plasmonic properties of nanomaterials has opened new paths for exploitation of surface enhanced Raman scattering (SERS) sensing. SERS is known as extremely sensitive analytical tool that can be applied in variety of areas: electrochemistry, analytical chemistry, chemical physics, solid state physics, biophysics and in medicine. Recently, Au nanoparticles were tested for detection of different biomarkers (such as for Alzheimer’s disease or cancer), herbicides and toxins. The crucial point in SERS is usage of noble metal nanoparticles that can enhance the extremely low signal of Raman scattering up to 108 times. Signal enhancement depends on the chemical composition of nanoparticles, shape and geometry of nanoparticles, and other properties. Aim of the project is to select strategy for the synthesis of metal nanoparticles and their modification for efficient detection of organic compounds using surface-enhanced Raman scattering.

Formation by physical vacuum techniques of thin-film catalytic structures
|
prof. dr. Giedrius LAUKAITIS |
state-funded |
Research Topic Summary.
The mechanism of bacterial adhesion to solid surfaces is a complex process affected by multiple factors. The most important property of bacterial adhesion mechanism is influenced by physicochemical interaction of the bacterial cells. The bacterial adhesion is determined by surface topography and roughness, free surface energy, including Van der Valse and electrostatic forces or acid-alkaline interactions, the potential arising in the phase boundary, hydrophobicity and surface charge. Surface derivatives, which are much smaller than bacterial cells, have been found to inhibit binding, reducing the interaction between bacterial cells and solids. The use of nanoparticles (metal and metal oxide) as antibacterial surfaces is a viable way. Most metallic or metal oxide nanoparticles (Ag, Fe3O4, TiO2, CuO, ZnO, etc.) have bactericidal properties through the generation of reactive oxygen species, although some of them are effective due to nanostructures and surface potential. Nano-particles formed on ceramic surfaces can disrupt the integrity of the bacterial cell membrane and its potential and activate the production of oxygen free radicals acting as nanocatalysts. The project will investigate: a) the formation of thin ceramic films by physical vapour deposition methods, selecting optimal forming technologies; b) the influence of technological parameters on the catalytic and antibacterial properties of the thin films; c) physicochemical investigation of the formed thin films. The aim of the project is to investigate the physical, chemical, and other characteristics of antimicrobial thin films and, on the basis of the research, cause the practical use of such systems.
