A comparative analysis of electrocaloric and barocaloric efficiency in ferroelectrics Rb x(NH 4) 1-xHSO4 and TGS is performed. A good agreement was found between intensive electrocaloric effects measured experiшentally and calculated using electric equation of state. Barocaloric effects were evaluated by analysis of t…
Quantum dots (QDs) have proven the potential for imaging contrast agents by the bright luminescence, the resistance against photobleaching, and the multiplexing capability. For the application of a targeted image contrast agent, hyaluronic acid-quantum dot conjugates (HA-QDs) were synthesized via a simple and novel el…
We have studied the effects of doping both non-magnetic and magnetic ions on the phase transitions and multiferroic ordering in two multiferroic oxides; Ni3V2O8 and FeVO4. Magnetic, dielectric, specific heat, polarization and AC susceptibility measurements were used to track changes in phase transition temperatures. W…
We present an efficient model for the simulation of phase-transformations and plasticity in polycrystalline materials. At the micro-scale, we implement a temperature-dependent scalar-valued phasetransformation model that is coupled to plasticity. The model allows to take into account an arbitrary number of independent…
This work presents the fabrication and characterization of 3 dimensional electrodes from pyrolysed carbon with spacing and diameter approaching the resolution limit of standard UV photolithography. Our carbon pillar arrays have a diameter of 1.4 µm, spacing of 5 µm and aspect ratio of about 8. We show their characteri…
Modern filter carbon fiber sorbents (CFS) marks the ASM-3, and ion-exchange fiber VION nonwovens have the highest efficiency in water purification from organic pollutants, heavy metal and hardness ions including Ca +2 and Mg +2.

No processo de enovelamento as proteínas seguem o principio de “mínima frustração”, garantindo ao estado nativo o seu mínimo global de energia e a sua estabilidade termodinâmica. Apesar de, a proteína estar no seu estado nativo, esta condição não impede o surgimento de algumas interações energeticamente desfavoráveis,…
L'imagerie moleculaire optique joue maintenant un role essentiel dans le diagnostic pre-clinique et le developpement de nouveaux medicaments. En effet, c'est un outil precieux dans la detection et le suivi de cellules vivantes que ce soit en utilisant de simples agents de marquage ou des sondes plus sophistiquees, dit…
Polystyrene (PS) has a wide range of technological applications due to the excellent bulk properties, but does not possess the unique surface properties for applications that require wettability, printability or cell adhesion. The following work focuses on surface modification of polystyrene by different techniques to…
The influence of magnetic-wave field on the thermal conductivity and microhardness of dispersion-filled polymer composites materials is examined

Katı madde taşınımının önceden hesaplanabilmesi, taşkın kontrolünde, barajlarda, sulama şebekelerinde vs. bu yapıların en iyi şekilde tasarlanmasında ve kullanımında etkili parametrelerden biridir.Bu çalışma kapsamında katı madde taşınımı problemi bir boyutlu olarak sonlu hacimler yöntemi kinematik dalga yaklaşımı ile…
Zuckersäureester zeichnen sich durch eine außerordentliche Reaktivität an ihren Carbonylfunktionen aus und vor allem die Aminolyse dieser aktivierten Ester ist von Interesse, da sie um Größenordnungen schneller abläuft als die von einfachen Estern. Die Amide entstehen hierbei schon bei Raumtemperatur auf der Minuten-…
TiFe intermetallic compound powder was coated by polymers polytetrafluoroethylene (PTFE) and polymethyl methacrylate (PMMA) using the mechanical treatment in high-energy planetary ball mill. The resulting metal-polymer composites have been studied by electron microscopy, differential scanningcalorimetry, thermogravime…
Compression of pipe parts in matrixes with funnel angles in 300, 450 and 600 is analyzed. The forms of loss of stability and corresponding to them parameters of initial thick-walled pipe parts and the tools are revealed. It is received quantitative evaluation of a thickening of the wall of the swaged pipes for a numbe…
The development of clean, sustainable chemical processes is a key priority towards meeting the growing demand for synthetic functional chemicals, while balancing rapidly depleting natural resources. The selective oxidation (selox) of crotyl alcohol to crotonaldehyde and the selective hydrogenation of benzyl cyanide to…
Les états spatialement localisés sont des solutions physiques possédant une structure spatiale particulière en une région bien définie d'un domaine structuré différemment. Nous nous intéressons aux états spatialement localisés susceptibles de se former lorsqu'une convection d'origine thermique est couplée à une convec…
The intensification of fast exothermic reactions can be achieved by using microstructured reactors (MSR) which provide improved mass & heat transfer rates leading to higher overall reaction kinetics. But for highly exothermic reactions the heat evacuation becomes not efficient enough and unwanted hot spots are formed.…
\n\t\t\t\t\tThe effects of strain rate on compressive and tensile strength of fly ash based geopolymer concrete were investigated experimentally. Four mixes of geopolymer concrete using different alkaline solutions and under vary curing conditions were prepared. One mix of ordinary Portland cement (OPC) concrete was p…
