We expect that this work will not only expand our fundamental understanding of this important class of materials but also provide the foundation for tailoring M/HEA properties through engineering lattice distortion and local chemical order.This is a preview of subscription content, access via your ...
The inspiration often comes from origin, mythical characters, place, physical or chemical properties, and more recently to commemorate the names of eminent scientists. Of course, the suggestion has to be ratified by the International Union of Pure and Applied Chemistry (IUPAC)....

Atmospheric Chemistry and Physics Simulating aerosol microphysics with the ECHAM/MADE GCM – Part I: Model description and comparison with observations The aerosol dynamics module MADE has been coupled to the general circulation model ECHAM4 to simulate the chemical composition, number concentration, and...
摘要: The equilibrium thermodynamic properties of gaseous mixtures at high temperatures are treated by an extension of the cluster theory of Ursell, omitting the assumption of additivity of pair energies. An effective partition function is introduced, which is a convenient function...
