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 ...

The porous (Ta0.2Nb0.2Ti0.2Zr0.2Hf0.2)C high-entropy ceramic possesses interconnected microspheres, abundant interface in the microspheres, and the severe lattice distortion of the high-entropy ...

It is possible to extract work from a quantum-mechanical system whose dynamics is governed by a time-dependent cyclic Hamiltonian. An energy bath is required to operate such a quantum engine in place ...
