Optical properties of PbTe and PbSnTe doped with Cr
(Elsevier, 2009)
Single crystal samples of PbTe and PbSnTe doped with Cr were made using the Bridgman technique. Far infrared diagrams of PbTe samples doped with 0.4 at.%, 0.8 at.% and 1 at.% Cr and also of Pb0.9Sn0.1Te doped with 0.4 at.%, ...
Characterization of silicon carbide ceramics obtained from porous carbon structure achieved by plant carbonization
(Elsevier, 2020)
The aim of this research was to obtain a carbon solid residue by the carbonization process of biomass in an inert atmosphere which, through physical activation and chemical treatment (using TEOS - tetraethyl orthosilicate) ...
Preparation and characterization of Cu and Zn modified nickel manganite NTC powders and thick film thermistors
(Elsevier, 2013)
A simple ball milling/thermal treatment procedure was applied to obtain fine thermistor powders. Three different powder compositions were analyzed–Cu0.2Ni0.5Zn1.0Mn1.3O4, Cu0.25Ni0.5Zn1.0Mn1.25O4 and Cu0.4Ni0.5Mn2.1O4. XRD ...
Photopyropiezoelectric elastic bending method
(AIP Publishing, 2003)
A method of investigation of semiconductors and metal–semiconductor structures based on two techniques: The elastic bending technique and pyropiezoelectric (PPE) technique was presented. The method was demonstrated on a ...
Changes in long-term properties and natural cycles of the Danube river level and flow induced by damming
(Elsevier BV, 2021)
In this paper we assessed changes in scaling properties of the river Danube level and flow data, associated with building of Djerdap/Iron Gates hydrological power plants positioned on the border of Romania and Serbia. We ...
Integer codes correcting double asymmetric errors
(The Institution of Engineering and Technology, 2016)
In this study, the authors present a class of integer codes capable to correct single and double asymmetric errors within a codeword. The encoding/decoding procedures for these codes are extremely simple, whereas the error ...
Soft chemistry routes for synthesis of rare earth oxide nanoparticles with well defined morphological and structural characteristics
(Journal of Nanoparticle Research, 2011)
Phosphors of (Y0.75Gd0.25)2O3:Eu3+ (5 at.%) have been prepared through soft chemistry routes. Conversion of the starting nitrates mixture into oxide is performed through two approaches: (a) hydrothermal treatment (HT) at ...
Poly(DL-Lactide-co-ε-Caprolactone)/Poly(Acrylic Acid) Composite Implant for Controlled Delivery of Cationic Drugs
(Wiley, 2019)
Poly(DL-lactide-co-ε-caprolactone)/poly(acrylic acid) implantable composite reservoirs for cationic drugs are synthesized by sequentially applying photoirradiation and liquid phase inversion. The chemical composition and ...
XPS and AES study of mixed layers of RuO2 and IrO2
(Elsevier, 1990)
The surface composition of RuO2+IrO2 mixed oxide layers (1-2 μm thick) deposited on titanium by thermal degradation of the corresponding chlorides in aqueous or isopropanol solutions has been investigated. A surface ...
Photoacoustic investigations of thermal and electronic properties of single crystal Ge doped with Cr
(E D P Sciences, Les Ulis Cedex A, 2005)
A high purity single crystal Ge with a (1 1 1) orientation was doped with Cr. A thin film of Cr was evaporated and then diffused into Ge substrate. The photoacoustic PA amplitude and phase spectra were measured and numerically ...
