In this method, the particles are treated with ammonia gas to get the nitrogen into the crystal structure. Alternatively, iron oxide can be mixed with ammonium nitrate in a planetary ball mill ...
Strain gauges that change colour when stressed, bright backlight-free displays and highly sensitive biological sensors are all potential applications of tunable photonic crystal materials ...
Reduction is the gain of electrons by a substance. It is also the loss of oxygen from a substance. For example, copper(II) oxide can be reduced to form copper when it reacts with hydrogen: ...
In the blast furnace, it is so hot that carbon monoxide can be used, in place of carbon, to reduce the iron(III) oxide: iron(III) oxide + carbon monoxide → iron + carbon dioxide The blast ...
Hexagonal close packing is one of two crystal structures that derive from stacking close-packed-planes of hard sphere atoms. In the HCP structure only two stacking ...
More than 4,000 naturally occurring minerals—inorganic solids that have a characteristic chemical composition and specific crystal structure ... tin, iron, marble, and granite.
It melts at 1410 C. The electronic configuration of the silicon atom is: (Ne)(3s) 2 (3p) 2, and the atomic radius is 0.132 nm. Silicon has the diamond cubic crystal structure with a lattice parameter ...
Particle edges are corrugated due to a misalignment in its crystal structure between the iron-rich octahedral layers and the silica-rich tetrahedral layers. "It produces a series of parallel ...
Chemical biology: development of novel molecular probes for DNA sequencing analysis and disease gene discovery Medicinal chemistry: development of new imaging and therapeutic agents towards cancer and ...
The government made the possession of nitrous oxide, or laughing gas, a criminal offence in England and Wales, as part of plans to tackle anti-social behaviour. Its use soared during the pandemic ...
