The phenomena, cavity formations and dynamics associated with rigid spheres entering into stratified, two-layer, oil-water systems were experimentally studied. The results were compared with available data for the corresponding type of cavities formed by spheres entering into single-phase, homogeneous liquids. The dis…
The kinetics of drugs photodegradation have traditionally been treated using thermal kinetic analysis methods consisting most commonly in zero and first order kinetics. These treatment strategies were shown to lack specificity and present a number of limitations when applied to photoreactions kinetics. Nevertheless, t…
The following investigation has the purpose of describing, both experimentally and numerically, the fracture behavior of a giant magnetostrictive alloy commercially known as Terfenol-D. Single-edge precracked specimens have been analyzed via three-point bending tests, measuring fracture loads in the presence and absen…
Non-aqueous lithium-oxygen batteries have been considered as one of the most promising power sources for electric vehicles and portable devices, due to the high theoretical capacity (3.86×103 mAh g-1) and energy density (1.14×104 Wh kg-1) [1]. The electrochemical reactions in the discharge and charge processes involve…
In this study, polyarylate nonwoven fabrics were manufactured by a wet-laid process by using viscose rayon and amorphous PET fiber as binding fibers. The engineering performance was evaluated after calendering to obtain a compact structure. From the polyarylate wet-laid nonwoven fabrics, it was conf...
Axial flux permanent magnet generator is well known on application of wind turbine electricity generation. The elimination of some iron core usage in the axial flux permanent magnet generator had significantly improve the generator’s efficiency compare to the conventional generator. However, the presence of cog cause…
Spintronics is the field concerned with the control of electron spin. In logic devices electron charge is manipulated, in computer data storage the magnetisation of a domain is altered; spintronics offers a hybrid between the two. This could be exploited in non-volatile random access memory cells for low power data st…
Η εργασία πραγματοποιήθηκε στο πλαίσιο του ερευνητικού προγράμματος «ΤεχνολογίαΣύντηξης» με απώτερο σκοπό την ανάπτυξη νέων δομικών υλικών για το μελλοντικό αντιδραστήρα σύντηξης. Τα υποψήφια υλικά βασίζονται σε κράματα Fe-Cr, τα οποία στο παρόν στάδιο ανάπτυξής τους δεν είναι ανθεκτικά στις συνθήκες λειτουργίας του μ…
The research investigated properties of aluminum bronze welded to structural steel St 52-3 N. Surface material CuAl-A3 was welded in one and two layers. There were dimension, metallographic examination of structures and hardness measured before and after heat treatment and after pressurization of tested specimens. It…
Im Rahmen des DLR-Projektes "Next Generation Car" wurde untersucht, inwieweit die Methoden zur Kennwertermittlung und die Simulationsmethodik der Kohäsivzonenmodellierung von Epoxidharz-basierten (EP) Klebstoffen auf Polyurethan-basierte (PU) Klebstoffe übertragen werden können. Hierfür wurde ein charakteristischer Ve…
Abstract : The objective of this project was to assess the effects of ionizing radiation on 3 classes of electromagnetic materials. The proposed approach for radiation detection was to utilize radiation-induced changes in dielectric permittivity, magnetic permeability, or electrical conductivity and monitor these chan…
본 연구에서는 고출력 자동차 헤드램프용 LD 에 적용 가능한 garnet 구조의 YAG : Ce 형광체 세라믹 플레이트를 제작하고 광학 특성을 분석하였다. 액상법을 이용하여 단분산된 구형 나노 YAG : Ce 입자를 합성하고 이를 $Al_2O_3$ 와 혼합하여 형광체 세라믹 플레이트를 제작하였다. 형광체 세라믹 플레이트의 두께를 $...
Introduction Studies designed to use large canine models and translate the results to human practice must take into account the ex vivo and in vitro differences in the bone marrow derived stem cells(MSCs) and their response to a covalently bound growth factor. Methods We analyze the activity of transforming growth fac…
Introduction Adipose-derived stem cells (ADSCs) possess the potential of multi-differentiation which could differentiate into neuronal cells and Schwann cells under certain conditions. If we inoculate the ADSCs modified by Brain derived neurophic factor(BDNF) and Neurotrophin-3(NT-3)double genes on the silk fibroin/ch…
In the paper presented investigations concerning the measuring sensibility of the adiabatic heat-pressure accumulation test are performed by using a well-known decomposition kinetic of a reference substance. The accuracy of the method has been proven by comparison with literature values for different substances. In su…
To improve the power quality based on T-transformer (T-connected) and a 3-leg VSC a 3-phase 4-wire DSTATCOM has been proposed in the paper. The Transformer(T-connected)connection is used to reduce current (neutral) while compensation of power(reactive power) and load balance is done with 3-leg source converter (voltag…
The development of organic electronics has progressed rapidly due to the demand for lower cost, large scale fabrication of devices using inexpensive materials with flexible substrates. The field has seen the discovery of many suitable organic substitutes for traditional electronic component materials, in particular, b…

Biomaterials are no longer considered innate structures and using functionalisation strategies to modulate a desired response whether it is a host or implant is currently an important focus in current research paradigms. Fundamentally, a thorough understanding the host response will enable to design propoer functional…
The serious potential consequences of the hazards posed by ammonium nitrate (AN) incompatibility (as the increase of explosive properties) provide motivation for a deeper understanding of the mechanisms of the reactions involved in these phenomena. Complementary to experimental methods, commonly employed to describe i…
