According to the first principles,the lattice structure,elasticity and electronic properties of three kinds of chromites spinel subject to slight structural variation are studied by the pseudowaves plane(PWP) approach based on density functional theory(DFT) and generalized gradient approximation(GGA).

The o\|Ps annihilation lifetime data show the structure transition in the coplymer.

This means the problem results from the structure transition between the agriculture industry and other industries, between urban and rural area.

La_(1-x)Sr_xCo_(1-y)Fe_yO_3 is synthesized by sol-gel method for the investigation of its chemical compositions and structure transformation at different temperature.

Microscopic studies of structural transition in iron under one-dimensional strain

When a series of voltage pulse is applied between the STM tip and the highly ordered pyrolytic graphite substrate, structural transition at molecular scale has been observed directly for PNBN thin films.

The primary content of the agricultural development in the course of the structural transformation is that the decrease of the agricultural percentage in the national economy goes contrary to the rise of modern technological content in agric.

We focused on the structural transformation of silk fibroin proteins at the air-water interface.

The structural transformation of the trivacant Keggin [α-A-AsW9O34]9-polyoxoanion to the saturated Dawson [α-As2W18O62]6-polyoxoanion has been firstly observed in the formation of 1,which provides a powerful experimental proof that saturated Dawson polyoxoanions can be viewed as the fusion of two trivacant Keggin polyoxoanions by sharing six oxygen atoms.
