To be eligible for JEE Advanced 2026, candidates must rank among the top 2.5 lakh students in JEE Main 2026, satisfy the age criteria. Additionally, candidates must have appeared for their Class 12 ...

Thermodynamic spontaneity—whether a reaction can go—can be measured by changes in either of two parameters: entropy or free energy.

A bomb calorimeter, as shown below, is a device that has an insulated container in which a sealed, oxygen-filled reaction vessel is surrounded by a known volume of water. This allows a complete ...

All chemical reactions involve an energy change. We categorise reactions by the direction of this energy change. If energy is released by a reaction, the reaction is exothermic. If energy is absorbed ...

Scientists have discovered a new way to store mechanical energy using twisted rods in specially designed metamaterials, delivering massive energy density gains and big potential for robotics and ...

An international research team has developed mechanical metamaterials with a high elastic energy density. Highly twisted rods that deform helically provide these metamaterials with a high stiffness ...

Be it springs for absorbing energy, buffers for mechanical energy storage, or flexible structures in robotics or energy-efficient machines: Storage of mechanical energy is required for many ...

A homogeneous mixture is also known as a solution. It is a substance composed of two or more substances that are distributed uniformly at a molecular level or microscopic. In easier terms, homogeneous ...

To biologists, a "species" is the fundamental unit of categorization for life on Earth and a key tool for protecting living creatures. When you purchase through links on our site, we may earn an ...
