Radiochemistry is the chemistry of radioactive materials, where radioactive isotopes of elements are used to study the properties and chemical reactions of non-radioactive isotopes (often within radiochemistry the absence of radioactivity leads to a substance being described as being inactive as the isotopes are stable). Much of radiochemistry deals with the use of radioactivity to study ordinary chemical reactions. This is very different from radiation chemistry where the radiation levels are kept too low to influence the chemistry.

Water desalination process and apparatus
ActiveUS20060060532A1Electrolysis componentsGeneral water supply conservationSolubilityWater desalination
A process and system for purifying water is disclosed. For example, in one embodiment, the process may be used to remove a divalent salt, such as calcium sulfate, from a water source in order to prevent the divalent salt from precipitating during the process. The water source, for instance, may be fed to an ion separating device, such as an electrodialysis device. In the electrodialysis device, an ion exchange takes place between the divalent salt and another salt, such as a monovalent salt to produce two concentrated salt streams that contain salts having greater solubility in water than the divalent salt. In one embodiment, the two salt streams that are produced may then be combined to precipitate the divalent salt in a controlled manner. During the process, various other components contained within the water feed stream may also be removed from the stream and converted into useful products. In one particular embodiment, the process is configured to receive a byproduct stream from a reverse osmosis process.

Reactor surface passivation through chemical deactivation
ActiveUS7118779B2Reduce the possibilityReduce buildMaterial nanotechnologyElectric discharge tubesCompound (substance)Product gas
Protective layers are formed on a surface of an atomic layer deposition (ALD) or chemical vapor deposition (CVD) reactor. Parts defining a reaction space for an ALD or CVD reactor can be treated, in situ or ex situ, with chemicals that deactivate reactive sites on the reaction space surface(s). A pre-treatment step can maximize the available reactive sites prior to the treatment step. With reactive sites deactivated by adsorbed treatment reactant, during subsequent processing the reactant gases have reduced reactivity or deposition upon these treated surfaces. Accordingly, purge steps can be greatly shortened and a greater number of runs can be conducted between cleaning steps to remove built-up deposition on the reactor walls.
