Dissolution-precipitation growth of uniform and clean two dimensional transition metal dichalcogenides

Two dimensional transition metal dichalcogenides (TMDCs) have attracted much interest and shown promise in many applications. However, it is challenging to obtain uniform TMDCs with clean surfaces, because of the difficulties in controlling the way the reactants are supplied to the reaction in the current chemical vapor deposition growth process. Here, we report a new growth approach called ‘dissolution-precipitation’ (DP) growth, where the metal sources are sealed inside glass substrates to control their feeding to the reaction. Noteworthy, the diffusion of metal source inside glass to its surface provides a uniform metal source on the glass surface, and restricts the TMDC growth to only a surface reaction while eliminating unwanted gas-phase reaction. This feature gives rise to highly uniform monolayer TMDCs with a clean surface on centimeter-scale substrates. The DP growth works well for a large variety of TMDCs and their alloys, providing a solid foundation for the controlled growth of clean TMDCs by the fine control of the metal source.     

A note on glass and silica in oil paintings from the 15th to the 17th century

This articles reports new discoveries relating to ground glass and silica in European easel paintings from the 15th to the 17th centuries that were created by various German, Italian and Netherlandish artists. The earliest known additions of these extenders date to the early 1430s. Glass powder of varying fineness, prepared from vessel or window cullet, is often found in red lake glazes as well as in other colours or preparatory layers of paintings. SEM/EDX analyses of the glass particles reveal a variety of chemical compositions (soda ash, wood ash, wood ash-lime, wood ash-lead, mixed alkali), which are discussed with respect to the provenance of the paintings. Historical sources on painting techniques mention glass additions most frequently to accelerate drying of oil paints, but also occasionally to facilitate grinding of pigments. Another possible function of powdered glass and silica, especially in oil-bound red lake glazes, is that of a transparent filler, as will be here discussed based on paint trials.     

对外汉语文化教学与体育文化融合的研究* ——对外汉语教材中体育元素呈现方式的探析

首先以对外汉语文化因素教学和体育文化的特点为背景,从体育词语的方面来探索体育与对外汉语教学的关联度.其次进一步从体育词语角度对比专业体育汉语《体育汉语主题词表》与《汉语水平词汇与汉字等级大纲》在体育元素呈现方式的区别.最后,立足于两者关联度,就对外汉语教学和教材两方面与体育元素的有效结合提出现实性与可操作性的建议.

校本教材建设的思考

随着我国课程改革的深入发展,校本教材日益被视为重要的教学资源,与统编教材共同构成了我国现代教育的教材体系。校本教材与统编教材是要对抗还是要融合,编写目标是适应现实还是促进发展,编写内容是重科学性还是求趣味性,其结果是加量还是增效,需要我们进行探索和反思,以期为课程改革的推进提供新的视角和路径。
