AFM and SEM-EDS examination of highly dispersed heteropolyacids supported on MCM 41 and SBA 15 mesoporous materials
(Natl Inst Optoelectronics, Bucharest-Magurele, 2009)
Heteropolyacids (HPAS) H(3)PMo(12)O(40) (HPM) and H(4)PVMo(11)O(40) (HPVM) supported on mesoporous pure-silica and Al, Fe modified molecular sieve MCM-41 and SBA-15 have been prepared and characterized by atomic force ...
Characterization of platinum deposited on carbon hollow fibers / carbon cryogel composites
(Journal of Optoelectronics and Advanced Materials, 2008)
Platinum supported on high surface area carbon material is one of the most intensively studied catalysts. However, physicochemical characteristics and surface chemistry of carbon influence properties of the support itself ...
SiO2 thin films obtained from silica sols by thermal spraying
(Journal of Optoelectronics and Advanced Materials, 2009)
The mechanism of the synthesis of silicon dioxide thin films on the surface of a stainless steel band substrate, by thermal spraying of a silica sol as a precursor was the subject of this work. The structural design of the ...
Phase equilibria investigation and characterization of the Au-In-Sb system
(Journal of Optoelectronics and Advanced Materials, 2008)
The Au-In-Sb system is of great interest recently, because its alloys belong to the group of potential lead-free solder materials to be used in electronics, while as a part of Au-ln-Sb-Te system, it presents a suitable ...
Far infrared and transport properties of single crystal PBTE samples doped with Ce
(Bucharest : National Institute of Research and Development for Optoelectronic, 2000)
Single crystal samples of lead telluride doped with cerium were made using the Bridgman technique. Single crystals could be easily cleaved parallel to the (002) plane. Room temperature far infrared reflectivity was measured ...
