Phosphate is a raw, naturally occurring form of phosphorus, which is one of the two most essential chemical inputs for the world’s most essential industry, agriculture. Unlike the other essential input, nitrogen, which is prevalent in the atmosphere and can be artificially fixed through the Hab...
With less food in the market, the countries would need to increase food imports, which would produce more global greenhouse gas emissions. Organic farming also increases the amount of absorbing carbon, a process where carbon dioxide (CO2) is "absorbed" out of the atmosphere and captured by ...
Xray diffraction analysis showes that partial bSiC crystal structure is brought about gradually from the pyrolysis products at 1050℃ to 1500℃ under nitrogen atmosphere. With the treatment temperature rising, the crystallinity of SiC and cristobalite obviously increases....

“The car industry must continue its dedicated work to minimise diesel engine emissions. But we should be aware that it is now beginning to cost a great deal to achieve very little.” Caption: Approximately three-quarters of all of the particulates in the Earth’s atmosphere are of natural ...
Currently available instruments measure the partial pressure of oxygen and call this the percentage of oxygen in the atmosphere. The partial pressure measurement is correlated with the percentage of oxygen with a manual adjustment mostly commonly made without information about humidity, temperature, baromet...
