We derive the differential probability of the photoelectric effect realized at the very low temperature of double graphene in the very strong magnetic field. The relation of this effect to the elementary particle physics, nuclear physics and Einstein gravity is mentioned. Our approach is the analogue of the Landau discovery of the diamagnetism, where Landau supposed the parabolic dispersion rel...

The upflow microbial fuel cell (MFC) system with membrane-free air-cathode was developed, and landfill leachate as fuel. The anode was made of stainless steel mesh filled with activated carbon, and carbon felt as the cathode. Electricity production performance of MFC with cylindrical stainless steel mesh anode filled with 0 (unfilled), 1mm, and 3mm cylindrical activated carbon particles was inv...

We used a molecular dynamics simulation with the modified Brenner reactive empirical bond order potential to investigate the erosion of a graphite surface due to the incidence of hydrogen, deuterium, and tritium atoms. Incident particles cause pressure on the graphite surface, and the chemical bond between graphene layers then generates heat to erode the graphite surface. We evaluated the speed...

materials with high electrical and thermal conductivity, respectively with microstructural stability and high temperature strength, are very attractive for the electricelectronic industry and special machine building industry (actively-cooled parts, rocket nozzles, magnet wire and cables, welding electrode tips). copper is one of the most promising metals for these applications because it has t...

Several recent experiments have provided compelling evidence for stable hybrid carbon nanotubediamond structures. In experiments by Kuznetsov et al. [1,2] the formation of nanometric closed curved graphitic structures with tubular or conical forms attached to a surface of a diamond particle were observed in high-resolution transmission electron microscopy (TEM) images of diamond particles after...

The influence of aluminum, within the range of 0.08 - 6.16 wt.%, on the microstructure and hardness of as-cast ductile cast iron has been studied. A number of irons of different composition have been made by green sand casting and gravity die casting of appropriate design to provide the experimental materials. It has been found that Al addition and higher cooling rates in permanent mould castin...
