Current-voltage characteristics of the In-ZnGa2Se4-In structure have been studied in the temperature range of 90–335 K. Based on the data calculated for the concentration of three trap types in ZnGa2Se4, the values N t = 1.4 × 1013, 8.2 × 1012, and 2.6 × 1012 cm−3 are obtained. The contact region transparency D * = 10…
Results of investigation of X-ray diffraction, infrared and optical spectra of powders of the ruthenium dioxide, lead-silicate glass as well as their mixture before and after sintering are reported. Sintering conditions typical for thick film resistors were used. Intensity of main lines of RuO2 in X-ray diffraction pa…
The synthesis of twelve asymmetric donor–acceptor distyrylbenzene derivatives with either one nitrile group or one, two or three nitro groups as electron acceptors, and one, two or three methoxy groups as electron donors is reported. Peak potentials obtained from cyclic voltammetry were combined with experimental UV/V…
A thermal energy balance model is developed for the monitoring of batch cooling crystallization processes and applied to the analysis of the crystallization of urea from an 80% methanol and 20% water solution using a 2-litre batch reaction calorimeter operating over a range of cooling rate from 0.1 °C min−1 to 0.5 °C…
Hot spots on a microelectronic package can severely hurt the performance and long-term reliability of the chip. Thermoelectric coolers (TECs) have been shown to potentially provide efficient site-specific on-demand cooling of hot spots in microprocessors. TECs could lengthen the amount of time a processor is capable o…
The two kinds of composites, including nano-nitrile butadiene rubber (NBR)/epoxy resin (EP) and nano-acrylate/EP composites were prepared with the three-roll mill. The effect of nano-particles on the mechanical property of epoxy resin composites were investigated by tensile strength testing. SEM images were taken to c…
In the present work the milling of three different aluminium titanium of the so-called gamma TiAl (or titanium aluminides) is presented. These alloys are solidified in gamma phase, being this a uncommon case in the industrial materials. This kind of titanium alloy presents improved mechanical properties even at high t…
2,5-Dihydroxybenzoic acid (DHBA) was found to show novel emission behavior depending on polarity of solvents. Fluorescence of DHBA has peaks at longer wavelengths as for a phenyl derivative and consists of three different components. They are zwitterion-type component produced by phototautomerism and anionic component…
We present results of photoluminescence (PL) studies of single SiO2 nanoparticles (SiO2 NPs) and single Si nanocrystals (Si NCs). Single particle spectroscopy reveals almost identical PL spectra for both kinds of nanosized systems. The emission curves exhibit a zero-phonon line and one or two phonon bands, which can b…
There are clear experimental evidences of the formation of either spherical or platelet γ-precipitates inside cubic γ’-precipitates in nickel-based superalloys, which strengthen the mechanical property of the alloy. In this work, molecular statics (MS) and dynamics (MD) simulations of the interaction between a super e…
TiN films were prepared on Ti(C,N)-based cermet substrate by laser chemical vapor deposition using titanium isopropoxide dipivaloylmethane [Ti(OiPr)2(dpm)2] and ammonia (NH3) as precursors. The effects of deposition temperature (Tdep) and laser power (PL) on the crystal phase, microstructure and adhesion were investig…
In this paper, reduced temperature combustion has been investigated at high load condition of a DI diesel engine. A three dimensional CFD model for flow field, spray, air-fuel mixture formation, combustion and emissions formation processes have been used to carry out the computations. The combined effect of EGR temper…
In the IPR-R1 TRIGA control room, analogue system based on relay-based logic was used, and mechanical strip chart recorders are used to measure, monitor and record the operational parameters. The same variables of the original control system are measured, although the reactor power was upgraded to 250 kW. For this new…
One-dimensional (1D) Te nanostructures are a recent focus in various 1D materials due to their interesting properties of photoconductivity, thermoelectric, catalytic activity and strong piezoelectric effect. In this work, we report a new synthesis method for water-dispersible 1D Te@ZnTe core–shell nanoparticles by usi…
Polymer-clay composites, which consist of clay particles dispersed in a polymeric matrix, have been used in different applications. Clay fillers are widely used in polymers as ways to produce cost-effective, strong, and energy efficient materials. The compounding and inclusion of particulate fillers in the polymers to…
Self-assembly between silver carboxylates with 2-aminopyridine derivatives give two silver(I) complexes, [[Ag(5MP)2(CNB)] · NH3 (I) and [Ag(3MP)2(HMB)] (II), where 5MP, CNB, 3MP, and HMB represent 2-amin-5-methylpyridine, 5-chloro-2-nitrobenzoate, 2-amino-3-methylpyridine, and 2-hydroxy-3-methoxybenzoate, respectively…
The combination of a ditopic ligand containing a functional "third site" as a bridge and organometallic half-sandwich iridium unit Cp*Ir as the corner leads to the formation of the tetranuclear metallamacrocycle 1, which is reacted with silver compound, resulting in the formation of mixed-metal infinitely tubular coor…
Abstract For understanding the macroscopic mechanical property of polycrystalline metal from a microscopic point of view, analysis of interaction between grain boundary (GB) and dislocations are very important. Especially, the driving force of each dislocation must be evaluated precisely, to apply the dislocation dyna…
