A catalyst is a substance that speeds up a chemical reaction. The catalyst is not used up or chemically changed during the reaction. Enzymes are catalysts that work inside the cells of living ...

Many technological applications, such as sensors and batteries, greatly rely on electrochemical reactions. Improving these technologies depends on understanding how electrochemical reactions work.

The enzyme Na⁺-NQR is a sodium pump that drives the respiration of many marine and pathogenic bacteria. Using redox reactions ...

Russia is stepping up covert attacks across Europe — rail sabotage, drones, cyberstrikes — testing NATO. Polish officials ...

A new technique, based on a chain reaction of recognition and hybridization events between two sets of DNA hairpin molecules, offers an enzyme-free alternative for the rapid detection of specific DNA ...

Experience a rainy day in Amsterdam as people move through the city streets with umbrellas, bicycles, and steady footsteps on wet brick roads. The scene captures everyday life continuing under soft ...

Food allergy symptoms in kids can show up within minutes to an hour after eating. They may affect breathing, skin, digestion, or the heart. A food allergy happens when the immune system overreacts to ...

Acetonitrile (CH3CN) is the simplest and one of the most stable nitriles. Reactions usually occur on the C N triple bond, while the C-H bond is very inert and can only be activated by a very strong ...

The same method is used as for carbon dioxide except zinc (or sometimes magnesium ribbon) is used in place of calcium carbonate. Collect 3 gas jars/test tubes of hydrogen gas in the same way.
