SIR NAPIER SHAW has recently devised a method of plotting upper air temperatures in the form of a curve which he has named a tephigram (T-ø-gram). The curve is plotted on squared paper on which the ...

Imagine a battery that’s safe, powerful, and works at normal room temperature—without the common problems of today’s energy storage systems. Scientists in China have now developed just that: the world ...

Scientists in China have developed a new kind of battery that could transform how we power everything from smartphones to ...

The phase diagrams show that the mixing behavior of these composites can have an unexpected dependence on the temperature, indicating that researchers should consider additional parameters when trying ...
