/GUIDE 122: GASES - OXIDIZING (INCLUDING REFRIGERATED LIQUIDS)/ Fire: Use extinguishing agent suitable for type of surrounding fire. Small fires: Dry chemical or CO2. Large fires: Water spray, fog or regular foam. Move containers from fire area if you can do it without risk. Damaged ...
CO2 reduction through artificial photosynthesis represents a prominent strategy toward the conversion of solar energy into fuels or useful chemical feedstocks. In such configuration, designing highly efficient chromophores comprising earth-abundant elements is essential for both light harvesting and electron tra...
Among gases important for CCS (CO2, N2, CH4, H2) CO2 has the highest heat of adsorption onto zeolites and other minerals with polar surfaces, and membranes made of these materials are therefore selective for CO2 at low temperatures. If adjacent adsorption sites are separated by an energy barri...
The chemical formula of a compound is a symbolic representation of its chemical composition. Chemical formulae provide insight into the elements that constitute the molecules of a compound and also the ratio in which the atoms of these elements combine to form such molecules. For example, the ...
