Photoemission electron microscopy (PEEM) employing phase-correlated femtosecond pulse pairs enables to investigate ultrafast dynamics of photo-excited nanostructured metals, where anomalous local fi eld enhancements are induced accompanied with surface plasmon resonances. Surface plasmon modes with specific coherence…
Stress-strain properties computations of furniture structural units have been performed. Group structure analysis of wood particle board durability was carried out by the means of the finite element method and experimental work. Efficient parameters of boards to be used in furniture structural units have been derived.…
The control of emulsion stability is of crucial importance in the process of crude/oil water separation, which is a key step in industrial oil production. Separation is enhanced if coalescence between droplets takes place, the extent of which will depend on the flow parameters as well as on the presence of emulsifying…
The authors present a method of homogenization used to solve nonlinear equilibrium problems of laminated plates exposed to transversal loads. The homogenization technique is a general and mathematically rigorous solution to elasticity problems. It describes the processes of deformation of composite structural elements…
The luminance and lifetime of OLEDs decrease dramatically with increased device operating temperature due to selfheating; this problem is particularly severe in OLEDs operated at high-brightness conditions. For stand-alone OLEDs, selfheating leads to measured rises in average temperatures of up to 60°C, with local tem…
In work tested method of extrusion for rods and tubes of compositions based on expanded graphite and various plastics, determined the strength characteristics of composites in compression, the features of the destruction process of polymer composite samples.
Abstract: The present work demonstrated to prediction of the damping property (tan delta) and delamination (interlaminar fracture toughness) in two types of stacking sequences first quasi-isotropic [0/90/45/-45? 6 q and second unbalanced stacking sequence [45/45/90/0? 6 q by dynamic mechanical analysis (Q880DMA) for…
We introduce a new photo electrode architecture, fabricated through facile synthesis of self-organized hollow TiO2nanocones under porous anodic alumina (PAA) featuring TiO2 nanotubes (NTs) within. PAA was grown directly on a fluorine-doped tin oxide substrate, which provided good contact for PAA-based dye-sensitized s…
We demonstrate performance and characteristics of a metamaterial absorber designed for operation in the THz regime. This absorber exhibits upto 90% absorbance and shows potential for use in sensor and detector devices.
The results on the formation of the contact thermal resistance in the area of section of metal surfaces with oxide films. At a special installation for the study of contact heat transfer experiments were conducted with contacting surfaces covered with oxide films of different thickness. We investigated the contact pai…
To broaden and lower the temperature window of the selective non catalytic reduction (SNCR) of nitric oxide (NO), the use of activated ammonia as the reduction agent was examined. A xenon excimer lamp emitting a wavelength of 172 nm (i.e., vacuum ultraviolet; VUV) was employed as the excitation source for molecular am…
Reproductive behaviour and aspects of group dynamics in the genus Acomys were studied in the respect to the individuals? physical condition, life history traits and social environment. Three of the presented studies reveal the important effect of social environment on the behaviour of group members to the new-coming m…
In order to satisfy future stringent regulations on vehicle emissions, a technique had to be created to achieve this. Exhaust Gas Recirculation (EGR) is a technique which has shown great potential and decent results in achieving this regulation. This technique is particularly known for its ability to reduce nitrogen o…
In this study, both sedimentation and thickening experiments were conducted for residuals produced from an advanced water treatment plant for more accurate and practical design of residual treatment train. In order to design a backwashed residual sedimentation basin (SRSB) in the filter backwash water recycle system,…
En este trabajo caracterizamos la primera permeasa identificada en hongos encargada de la excrecion de nitrato al medio extracelular, asi como el impacto que tiene esta proteina en la via de asimilacion de nitrato en Hansenula polymorpha. Asi mismo, identificamos que la quinasa Npr1 participa en la regulacion del tran…
Dynamic reciprocity, the spatio-temporal bidirectional process between evolving partners in a functional system is not only found in nature, but also applies to supramolecularly assembling architectures. In this thesis, the focus was on the understanding of nature-inspired supramolecular self-assembly processes and me…
Este trabalho descreve a modelagem de geradores síncronos utilizando o método de reconstrução do campo. Os conceitos do método são apresentados e a metodologia de modelagem é desenvolvida em conformidade com o tipo da máquina síncrona: rotor saliente ou rotor não-saliente. Os modelos obtidos são então utilizados como…
V diplomskem delu so obravnavana visokotrdnostna jekla za gradnjo hidroopreme. Pri varjenju teh jekel se najpogosteje pojavljajo kriticne mikrostrukture z izrazito krhkostjo v toplotno vplivanem podrocju. Zaradi navedenega moramo posebno pozornost posvetiti metalografski analizi nastalih realnih mikrostruktur zvarnega…
The evolution of material design has mirrored advancements in the understanding of materials, nature, and the requirements of target applications. Originally, materials were only intended to play a passive role, but with a deepened understanding of material properties and design has come an improved ability to harness…
As the SiO2-based classical transistor reaches its scaling limit, a broad range of alternate dielectric materials are being explored for classical CMOS as well as other emerging technologies. These include high-k materials for gate dielectrics; low-k materials for interlayers; extreme high-k, ferroelectric materials f…
