Obesity is a physiological condition of chronic positive energy balance. While the regulation of energy metabolism varies widely among individuals, identifying those who are metabolically prone to ...

Calorimetry measures the amount of heat released or absorbed during a chemical reaction. It is a beneficial and powerful tool that accurately evaluates chemical processes, helps researchers assess ...

Users can use simple equipment to measure enthalpy, a term often associated with physicists but significantly relevant to daily life. Heat transfer plays a pivotal role in all these processes, and ...

The purpose of the whole-room indirect calorimetry suite is to provide measurements of human energy expenditure and substrate utilization, both long-term (24-hour) and short-term (1–6-hour), for ...

Researchers from Ruhr University Bochum, Germany, have developed a new method that allows them to visualize the contribution of the interaction between water and proteins for the first time with ...

Like someone who finally sits after a long, tiring day of standing, gas-phase molecules breathe a sigh of relief, so to speak, as they “take a seat” (adsorb) on solid surfaces. The sigh comes in the ...

What is a calorie? While most people think of calories in relation to food, calories are simply a unit of heat energy. In fact, measuring calories is essential to energy science because every chemical ...

Energy can be released in chemical reactions as light, sound or electrical energy. But it is most often released as heat energy. Measuring heat transfers is called calorimetry. The diagram shows a ...

During EV usage, the energy contained in a battery is released through exothermic chemical reactions, which release large volumes of heat energy. Batteries are designed in such a way that this heat ...
