Lithium-ion batteries are a kind of rechargeable battery that is charged or discharged through desorption or insertion of lithium ions (Li +) from or into the active material structure. In recent ...

Many mechanical tests of composite materials require the compression loading of a test fixture. These include not only compression test methods, but also many shear, flexure, curved-beam strength, ...

Test compression sounds like magic. Read on to learn how this trick is done. Large, complex ICs are viable because their design meets test as well as functional requirements. Design for test (DFT) was ...

I noted in a 2005 column (see "Current compression test methods" under “Editor's Pick,” at top right) that there are three basic methods of loading a composite material test specimen in compression: ...

IC designers now have a powerful weapon in the struggle against rising test costs: commercially available EDA solutions that provide fast and effective means to implement scan compression on-chip. By ...

The purpose of your engine is to compress fuel and air and then ignite it, creating heat energy that then makes mechanical motion. If your engine can't compress the air and fuel properly, the engine ...

People tend to spend, on average, several hours a day sitting on couches, chairs, and car seats, as well as considerable time on mattresses every night. Polyurethane foam plays a major role in ...
