This study describes a world of new carbon “fullerene” allotropes that may be synthesized by molten carbonate electrolysis using greenhouse CO2 as the reactant. Beyond conventional diamond, graphite and buckyballs, vast array unique nanocarbon structures exist. Until recently, was thought to unreactive. Here, we show can transformed into distinct nano-bamboo, nano-pearl, nano-dragon, solid holl...

This paper aims to explore the effect of O2 on the nano-indentation of diamond cubic silicon using molecular dynamics simulation. Obtained with the aid of the Tersoff potential for Si–Si interactions and the Morse potential for all other interactions, the results show that on indentation, the O2 molecule in the appropriate position and orientation dissociates into oxygen atoms, penetrates into ...

Powder metallurgy has been used for the manufacture of fully dense, which have not reacted composites consisting of a matrix of copper containing 50 -60 vol% particles with negative thermal ZrW2O8 expansion. On cycling between 25 and 300°C, the compounds showed coefficients thermal expansion which varies rapidly with temperature and significantly larger than expected by theory. Improvements in ...

Boron doped diamond (BDD) is an outstanding electrode material with unique electrocatalytic properties and excellent stability, relevant to electrochemical advanced oxidation processes electroanalytical techniques. From environmental sustainability viewpoint, BDD electrodes are comprised only of earth abundant elements (carbon, boron, oxygen). However, a major drawback the high manufacturing co...
