Generally, gold nanoparticles are produced in a liquid ("liquid chemical methods") by reduction of hydrogen tetrachloroaurate (HAuCl4), although more advanced and precise methods do exist. After dissolving HAuCl4, the solution is rapidly stirred while a reducing agent is added. This causes Au3+ ions to reduce to un-ionized gold atoms. As more and more of these gold atoms form, the solution becomes supersaturated, and gold gradually starts to precipitate in the form of sub-nanometer particles. The rest of the ...

Chloroform was discovered in July, 1831 by American physician Samuel Guthrie (1782-1848), and independently a few months later by French chemist Eugène Soubeiran (1797-1859) and Justus von Liebig (1803-1873) in Germany. Soubeiran, who produced chloroform through the action of chlorine bleach powder (calcium hypochlorite) upon acetone (propanone) or ethanol (an application of the generic process known as the haloform reaction). Chloroform was named and chemically characterised in 1834 by Jean-Baptiste Dumas (1800-1884). Its anaesthetic properties were noted early in 1847 by M ...

Weighable amounts of californium make it possible to determine some of its properties using macroscopic quantities. Californium-252 (2.6 year half-life) is a very strong neutron emitter and is thus extremely radioactive and harmful (one microgram spontaneously emits 170 million neutrons per minute). The decay of californium-254 (55-day half-life) may have been detected through telescopes in supernovae remnants. Californium-249 is formed from the beta decay of berkelium-249 and most other californium isotopes are made by subjecting berke ...

Cyanogen is a chemical compound (CN)2. The CN entity behaves like a halogen. As do halogens, it forms molecules consisting of two CN groups, N≡C-C≡N. Compounds containing the CN group are called cyanides, cyanates, and thiocyanates. "Cyanogen" refers to a single CN group in some molecules, such as cyanogen chloride (NCCl). Cyanogen at room temperature is a colourless gas with a pungent odour. Its melting point is -27.9°C (-18.2°F) whilst its boiling point is -20.1°C (-4.2°F). Its density is approximately twic ...
