Ever-increasing energy requirement and exhaustion of fossil fuels demands improving efficiency of energy usage as well as seeking sustainable and renewable resources. Energy storage capacitors are devices that could take this responsibility, and have been the focus of increasing attention due to their advantages such…
Bislang erfolgte die Berechnung von Verzahnungskorrekturen in Planetengetrieben für einen bestimmten Betriebszustand.\nDa jedoch die Lasten in der Praxis schwanken, ist es erforderlich, die Verzahnungskorrekturen für das vorliegende\nLastkollektiv zu bestimmen. Auch die Lagerkräfte stellen sich für eine korrigierte Ve…
This research strived to examine the potential for carbon fibre to improve the strength characteristics of ceramic water filters (CWFs) to improve their length of use in the field while maintaining, or improving, existing flow and bacteria attenuation capabilities. Model-scale CWF discs were made exploring several con…
We present experimental and theoretical studies of sp3 materials, alkaline-earth-metal (AEM) disilicides, disilane (Si2H6) and carbon at high pressure. First, we study the AEM disilicides and in particular the case of a layered phase of BaSi2 which has an hexagonal structure with sp3 bonding of the silicon atoms. This…
Proceedings of the National Academy of Sciences (PNAS), a peer reviewed journal of the National Academy of Sciences (NAS) - an authoritative source of high-impact, original research that broadly spans the biological, physical, and social sciences.
Modern charge-density analysis, edited by C. Gatti and P. Macchi, Berlin, Springer, 2012, xxiii + 783 pp., ISBN 978-90-481-3835-7 In 1968 Coppens and Hamilton wrote (1): ‘The recent interest in dev...
The fluorescence spectra of the porous silicon modified by water solutions of biologically active materials and materials of biological origin are recorded as well as the fluorescence spectra of the porous silicon modified by lecithin monolayers grown on the surface of water solutions of the biologically active materi…
Odonata apresenta alta diversidade de espécies nas regiões tropicais, no entanto, ainda há grandes lacunas de conhecimento em muitos biomas, incluindo a floresta Amazônica. A maioria dos estudos realizados com Odonata na região Neotropical tem como foco os adultos, dessa forma, a taxonomia e biologia das formas imatur…
It is known that reduced sulfur compounds (such as thiocyanate and thiosulfate) can accelerate active corrosion of austenitic stainless steel in acid solutions, but before we started this project the mechanism of acceleration was largely unclear. This work combined electrochemical measurements and analysis using scann…
The article describes the methods of mathematical modeling, use of which is desirable to select the optimal process parameters for making castings, particularly in the design phase of mold technology.
Circular bars of the Zn-22Al-2Cu alloy were prepared by utilizing the semi continuous vertical casting technique. Solid as cast showed high values in the mechanical strength (497 MPa) and hardness (71 RB). The micro structure of the bars consisted of equiaxed dendrites with eutectoidal composition surrounded by eutect…
UV cured epoxy systems represent complementary technology to the established heat cured epoxy systems for coating, adhesion and encapsulation of electronic devices. The UV cured epoxy systems offer significant benefits in terms of fast cure and thus very short production cycle time; low stress and better colour due to…
Oriental Journal of Chemistry is a peer reviewed quarterly research journal of pure and applied chemistry. It publishes standard research papers in almost all thrust areas of current chemistry of academic and commercial importance. It provides a platform for rapid publication of quality research papers, reviews and ch…
This paper reports the particle size characterisation of mechanically alloyed La0,5Sr0,5Fe0,5Mn0,25Ti0,25O3 prepared with the assistance of a high-power ultrasonic treatment. After a solid-state reaction on quasi-crystalline powders at 1000°C for 3 hour, the presence of a single phase was confirmed by X-ray Diffractio…
Lost foam casting as a relatively new manufacturing process is extensively employed to produce sound complicated castings. In this study, an experimental investigation on lost foam casting of an Al-Si-Cu aluminium cast alloy was conducted. The research was aimed in evaluating the effect of different pouring temperatur…
The effect of the density dependence of symmetry energy on fragmentation is studied using isospin-dependent quantum molecular dynamics model(IQMD) Model. We have used the reduced isospin-dependent cross-section with soft equation of state to explain the experimental findings for the system 79 Au 197 + 79 Au 197 for th…
The complexation of urea (U) with mercury(II) and nickle(II) ions at room temperatures and 60 oC has been studied by many methods namely elemental analysis, magnetic susceptibility, conductivity measurements, infrared and thermal analysis (TG/DTG), scanning electron microscopy (SEM), Energy-dispersive X-ray spectrosco…
A performance in a wet granulation of mixed oxide (MOX) powders prepared by the microwave heating de-nitration method was examined to fabricate MOX fuel pellets for fast breeder reactor at an extremely simplified process. An agitating granulator equipped with three blades and a chopper was used and its performance was…
/-methylphenyl)-2-mercaptothiazole (MPMT) was synthesized from a compound of thiocarbamate family using condensation reaction. The spectroscopic properties of this structure were studied using 1H-NMR, 13C-NMR, FT-IR, Mass Spectroscopy, and elemental analysis methods. Subsequently, its thermodynamic parameters were exa…
Here, we present a coarse-grained model targeted for implicit solvent simulations of unfolded or intrinsically disordered proteins. The hierarchical model with its nonspherical building blocks allows one to reproduce the local dynamics of the backbone with simple harmonic bonds and steric collisions between a small nu…
