Chain aggregates of MoO3 nanoparticles have been obtained and their polymer-like properties revealed. Chain aggregates of MoO3 nanoparticles, like polymers, form parallel packings, coils and exhibit coil-helix transition, Brownian motion, and high flexibility. 相似文献

We discuss some basic regularity properties of the area-preserving deformations ${u:\Omega \mapsto \mathbb{R}^2}$ that have minimal elastic energy ${\int \limits_\Omega|\nabla u|^2}$ among a suitable class of admissible vectorfields defined on a smooth, bounded domain ${\Omega\subset \mathbb{R}^2}$ . Although we restrict ourselves to the quadratic stored energy function and 2-space, most of our results extend to three dimensional setting with convex stored energy function. 相似文献

A new method for integrating anomalous Ward identities and finding the effective action is proposed. Two-dimensional supergravity
and W
3-gravity are used as examples to demonstrate its potential. An operator is introduced that associates each physical quantity
with a Ward identity, i.e., a quantity that is transformed without anomalous terms and can be nullified in a consistent manner.
A covariant form of the action for matter fields interacting with a gravitational and W
3-gravitational background is proposed.

The paper studies the properties of β-uniform Dirichlet algebras and maximal β-uniform algebras. A method is given for construction of a β-uniform Dirichlet algebra and a maximal β-uniform algebra by means of a uniform Dirichlet algebra and amaximal uniform algebra respectively. As a consequence, an analog of the Bishop-Shilov theorem on antisymmetric partition is obtained. 相似文献

Electron diffraction patterns of silicon in transmission with contrast reversal from bright to dark for an unidentified Kikuchi line along its length have been obtained. The contrast reversal of an unidentified line is explained within the elementary mechanism of Kikuchi pattern formation taking into account the Kikuchi electron double diffraction. 相似文献
