The report of room-temperature superconductivity in hydride materials at extremely high pressures has attracted not only worldwide interest but also controversy (C&EN, Oct. 19, 2020, page 7). Those ...
Some chemical reactions change temperature, change color, produce a gas, or make a solid from two liquids. Try this reaction and see what it does! Pour 1 tablespoon of hydrogen peroxide into a cup.
Ammonia (NH3) is a colorless chemical compound comprised of nitrogen and hydrogen that is widely used in agriculture and in ...
Differential scanning calorimetry (DSC) is used to measure heat flow into or out of a sample as it is exposed to a controlled thermal profile. DSC offers both quantitative and qualitative data about ...
When microwave ovens started appearing in chemistry labs in the late 1980s, it wasn’t just to heat up leftovers for lunch or to make popcorn or a frozen burrito for a late-night snack. Imaginative ...
Introduction Have you ever wondered how all the food that you eat gets digested? It is not only the acid in your stomach that breaks down your food—many little molecules in your body, called enzymes, ...
Photosynthetic electron transport reactions of succulent plants from hot deserts are able to tolerate extremely high temperatures and to acclimate to seasonal increases in temperature. In this study, ...
