In a pioneering move, one hundred and fifty years ago the Russian organic chemist Aleksandr Butlerov (1828–1886) coined the
term “chemical structure.” He called for basing our understanding of the chemical composition of substances on the concepts
of atomicity and structure. 相似文献

This paper summarises the experience we gained while going through an accreditation process in accordance with the requirements of ISO/IEC 17025 Standard. We propose in this paper an initial path finding study stage to evaluate the laboratory's predisposition for, and the benefits of, accreditation. We also present a conceptual framework as part of the path finding study stage to identify and classify different groups of activities in a laboratory into separate business domains. The objective of the study is to assess, for each business domain, the approach, the benefits, costs and implications of working with a systematic QA and then design a priori appropriate working systems tailored to the real needs of each business. Such a study should naturally lead to an appropriate definition of accreditation scope.

Crystal facet engineering of semiconductors has become an important strategy for fine-tuning the physicochemical properties and thus optimizing the reactivity and selectivity of photocatalysts. In this review, we present the basic strategies for crystal facet engineering of photocatalysts and describe the recent advances in synthesizing faceted photocatalysts, in particular TiO(2) crystals. The unique properties of faceted photocatalysts are discussed in relation to anisotropic corrosion, interaction dependence of adsorbates, photocatalytic selectivity, photo-reduction and oxidation sites, and photocatalytic reaction order. Ideas for future research on crystal facet engineering for improving the performance of photocatalysts are also proposed. 相似文献
