(Slightly)Category:Research Tools; Materials;Applications:Ammonium Persulfate is used as a reagent in the low temperature synthesis of carbon-encapsulated spherical Fe7S8 nanocrystals as high-performance anode for lithium-ion batteries.Not a dangerous good if item is equal to or less than 1g/ml ...
Balance the chemical reaction by making sure that you have the same number of atoms of each molecule on the reactant and product sides of the equation. In a simple example in which water and carbon react to form carbon monoxide and hydrogen gas, the balanced equation looks like this: H2O ...

If DeltaH is the enthalpy change and DeltaU the change in internal energy accompanying a gaseous reaction, then
Owing to China’s massive area and vastly differing regional variations in the types and efficiency of energy, the spatiotemporal distributions of regional carbon emissions (CE) vary widely. Regional CE study is becoming more crucial for determining the
The thermochemistry and trends in kinetic parameters for the hydrogen shift reactions from each carbon (4-8-member-ring TST's) in n-butyl and n-pentyl peroxy radicals (CCCCOO center dot and CCCCCOO center dot) are analyzed using density functional and ab initio calculation methods. ...
