We’ve all seen, and occasionally wrestled with, bill acceptors like the one [Another Maker] recently liberated from an arcade machine. But have you ever had one apart to see how it works?

Developing high-performance gas sensors for the detection of lung cancer markers at low concentrations is a crucial step ...

Researchers often study biomolecules such as proteins or amino acids by chemically attaching a "fluorophore," a sensitive ...

Al-Baqarah 37: “Then Adam was inspired with words (of prayer) by his Lord, so He accepted his repentance. Surely He is the ...

Polyimide (PI) has emerged as a promising organic photocatalyst owing to its distinct advantages of high visible-light ...

The screws should be above the acceptor tray. Loosen it just enough to tilt the tray forward. Lift up the tray or slot and set aside. Disconnect the colored ribbon connector, usually gray ...

Organic solar cells typically rely on an active layer called a bulk heterojunction—comprised of electron donor and acceptor materials—to capture and convert sunlight. Upon contact, sunlight ...

A research team led by Prof. CUI Linsong from the University of Science and Technology of China (USTC), in collaboration with ...

Oxidation describes a type of chemical reaction in which electrons are transferred from one molecule to another, changing the composition and energy content of both the donor and acceptor molecules.

Cytochrome oxidase transfers electrons from the electron transport chain to oxygen (the final electron acceptor) and reduces it to water. In the oxidase test, artificial electron donors and acceptors ...
