of semiconductors is one of the mostcomplex and sophisticated processesin all of manufacturing. Semiconductor fabrication requires precision down to the nanometer (that’s one-billionth of a meter), atomic ordering, and high chemical purity. And many semiconductor fabrication plants have daily quotas ...
Clean energy is essential to combating climate change and achieving a sustainable future. But what exactly does it mean? Is clean energy the same as renewable or green energy?
Of these, monoethanolamine (MEA) is perhaps the most well-known, thoroughly studied, and readily available, yet likely cannot meet the stringent energy and cost limitations required to economically achieve 90% CO2 capture at coal-fired power plants. Also in development are piperazine (PZ) and ...
717.Artemisinin has become a vital part of the treatment for malaria, and is thought to save 100, 000 lives a year in Africa alone. 青蒿素成了抗疟疾药物的关键成分,据估计每年仅在非洲就挽救了10万人的性命。 718.Tu...
Depending on the country’s law, electricity may be generated through various means, such as power plants, renewable sources, or coal. Battery Contrary to popular belief, batteries do not store electricity or electric current. Instead, they act as storage devices for chemical energy. Inside the ...

Plants make and store cyanide in their cells. What is the purpose of cyanide in plants?Cyanide:Cyanide is a chemical that is highly toxic. Compound is able to inhibit cytochrome C oxidase, which is also known as complex for in the electron transport chain....
What is hydrogen? Hydrogen is a clean alternative to methane, also known as natural gas. It's the most abundant chemical element, estimated to contribute 75% of the mass of the universe.Here on earth, vast numbers of hydrogen atoms are contained in water, plants, animals and, of course,...
What are the energy producing units of a cell? What is the role of activation energy in a chemical reaction? Which may be true for a substance that absorbs energy? What are the units of activation energy? What are the energy transfer mechanisms in plants? What type of chemical reactions ...
Much current work is focused on the production of fuels from biological materials. That isn’t a new idea: Oil, gas and coal all started out as animals and plants millions of years ago. Today’s biofuel technologies simply replace millennia of geological squeezing with faster chemical and biolo...
