Thermoelectric materials are used in thermoelectric systems for cooling or heating in niche applications and are being studied as a way to regenerate electricity from waste heat.Thermoelectrics study the direct inter-conversion between heat flow and electrical power, which has a wide range of applications including power generation and refrigeration.

The peripheral discharge type of Ball-Rod Mill is a modification of the grate type, and is recommended where a free gravity discharge is desired. It is particularly applicable when production of too many fine particles is detrimental and a quick pass through the mill is desired, and for dry grinding.

A flow control valve used in the oil and gas industry can have a globe, butterfly, or ball shape, and is available in multiple material grades and sizes. The most used type of actuator is the air-operated, as it involves less ancillary equipment (as cabling, switchgear) when compared to other types of actuators.

Before the discovery of High Entropy Alloys, it was believed that combining multiple elements in near equimolar compositions would result in a mixture of brittle compounds with no significant technological application. In contrast to those beliefs HEAs commonly consist of a sole solid solution or a mixture of solid solution phases.
