Monte Carlo calculation of x-rays deposited energy in CdZnTe detector
(Trans Tech Publications Ltd, 2007)
CdZnTe detectors have been employed in diagnostic X-ray spectroscopy. This paper presents the Monte Carlo calculation of X-ray deposited energy in a CdZnTe detector for different energies of photon beam. In incident photon ...
Electrical conductivity of fullerene derivatives
(Trans Tech Publications Ltd, 2002)
In this paper electrical conductivity of fullerene derivatives was investigated. Compared with pure fullerene (molecule C-60), which is an insulator (10(-12) Sm-1), the measured C-60(OH)(24) shows several order of magnitude ...
Different aspects of electrochemical investigations of carbon soot containing endohedral fullerenes and C60 molecules in neutral and alkaline electrolytes
(Trans Tech Publications Ltd, 2002)
In this paper we report the results of our investigation of different electrochemical activities of pure carbon dust, pure metals (Cu and Zn), pure fullerence C60 (99.95% purity), different mixtures of these materials, and ...
Influence of radiation effects on the electrical characteristics of photodetectors
(Trans Tech Publications Ltd, 2002)
Radiation effects in photodetectors (photodiodes) induced by various sources and fluences were studied in this paper. The influence of irradiation was determined by forward current-voltage (I-V) measurements of electrical ...
Laser light scattering in spray system control
(Trans Tech Publications Ltd, 2002)
A technique applicable to spray systems research and control, based on the measurements of the spatial frequency of scattered light intensity, is presented. Phase Doppler anemometry - a frequently used technique in spray ...
HEMT carrier mobility analytical model
(Trans Tech Publications Ltd, 2005)
In this paper a new analytical carrier mobility model of a heterostructure unipolar transistor, High Electron Mobility Transistor (HEMT), is presented. The influence of the two dimensional electron gas confined in a HEMT ...
Finite element modeling of mechanical properties of particulate composite biomaterials
(Trans Tech Publications Ltd, 2002)
The influence of inclusion geometry and volume fraction on stiffness behavior of a particle hydroxyapatite filled polymer (poly-L-lactide and collagen) matrix composite was investigated by finite element. analysis. The ...
Extraction of parameters from I-V data for nonideal photodetectors: A comparative study
(Trans Tech Publications Ltd, 2005)
Parameters that characterize semiconductor devices are often determined with difficulty, and their values very frequently depend on the method used for measurements and analysis. The extraction of diode parameters from the ...
Effects of structure characteristics on mechanical properties of aluminum alloy matrix composites
(Trans Tech Publications Ltd, 2004)
Composite materials based on the CW67 alloy (Al base matrix) and volume fraction of 15 pet of SiC particles in two nominal sizes (0.7 μm and 33 μm) have been produced by hot pressing. The fracture behavior of the composite ...
In vitro and in vivo investigation of collagen - C-60(OH)(24) interaction
(Trans Tech Publications Ltd, 2004)
In this paper both theoretical and experimental approach to a possible interaction between collagen hydrolyzate and fullerole C-60(OH)(24) have been considered. In vitro and in vivo experiments were performed. Based on ...
