Half-metallic ferromagnetism in Al1-xCrxP and superlattices (AlP)n/(CrP)m by density functional calculations
(Elsevier, 2014-01)
Using the first-principles full-potential linear muffin-tin orbital (FP-LMTO) method based on density functional theory, we have investigated the electronic structure and magnetism of order dilute ferromagnetic semiconductor ...
Structural, chemical bonding, electronic and magnetic properties of KMF₃ (M = Mn, Fe, Co, Ni) compounds
(Elsevier, 2014-04)
KMF₃ (M = Mn, Fe, Co, Ni) compounds crystallize in the cubic perovskite structure with space group Pm3m (#221) at ambient conditions. Structural, chemical bonding, electronic and magnetic properties of these compounds are ...
Effect of substrate bias in copper sputtering plasma measured by Langmuir Probe
(Trans Tech Publications Inc., 2014-04)
There are several techniques to deposit the metal oxide thin film such as electron beam evaporator, pulse laser deposition and reactive magnetron sputtering deposition. In this experiment, magnetron sputtering deposition ...
Design development of acoustic waves based sensitive sensors for Escherichia coli O157:H7 detection
(Trans Tech Publications Inc., 2014-04)
Food contamination has become critical issue and is being worse due to the insensitive detection devices. One of the dangerous food contaminations is by Escherichia coli (E.coli) O157:H7, one of the harmful bacterial ...
Microstructure and in-vitro test bioactivity behavior of Co-Cr-Mo (F-75)/hydroxyapatite in phosphate buffered saline solution
(Technical University of Košice, 2014)
Cobalt based alloys were the first metallic materials successfully used in orthopedic applications. However, these alloys are bioinert, it is necessary to make them bioactive in the human body to improve their application ...
Reconfigurable four-parasitic-elements patch antenna for high-gain beam switching application
(Institute of Electrical and Electronics Engineers (IEEE), 2014-01)
A reconfigurable beamforming of a four-para-sitic-elements patch antenna (FPPA) for WiMAX application is presented. The proposed FPPA is successfully capable to steer the
radiation pattern in azimuth planes (0°,45°, 135°, ...
