This increase in atmospheric methane concentrations not only influences the climate directly, but also indirectly through chemical reactions. Here we show that the climate effects of methane's atmospheric chemistry have previously been overestimated, notably by the Inter-governmental Panel on Climate ...
of methane depends on the rate of its destruction by the hydroxyl radical. The concentration of ozone depends on various short lived precursor gases (carbon monoxide, oxides of nitrogen, and non-methane hydrocarbons) and transport from the stratosphere.Chemical Climate Changes In The OceanThe interna...
Chemical reactions (化学反应) make for some great experiments (实验). You can make use of the CO2 (carbon dioxide) given off by a baking soda (小苏打) and lemon juice reaction to blow up your balloon! What you’ll need: Balloon
The nature of entropy change in the global climate system: A review of the maximum entropy production principle Since an early work by Paltridge (1975) the mean state of the global climate has been suspected to exhibit a state of maximum entropy production. This proposition was doubted by Essex...
“Earth can be a factory for chemical production,” says Iwnetim Abate, an MIT professor and author of the new study. This idea could be a major change for the chemical industry, which today relies on huge facilities running reactions at extremely high temperatures and pressures to make ammoni...

Many fabrication processes and materials design issues require a deep understanding of the underlying chemistry, physics and mathematics, and especially of thermodynamic and kinetic processes coupled to chemical reactions and reactor design that are the hallmark of a classically trained chemical engineer. ...

The overall reactions of the CLC and CLR systems are full oxidation (e.g., Eq. 3) and partial oxidation (e.g., Eqs. 1, 2, and 4), respectively. Rational design of CLR reactor system to decouple these reactions and oxygen carriers with high fuel conversion and product selectivity could...
