Impact of Small Steel Spheres on the Surfaces of "Normal" and "Anomalous" Glasses

High-speed photography (framing rate of 10⁶ s^-1) has been used to follow the formation and growth of damage in a number of oxide glasses when impacted with 1-mm-diameter steel balls at velocities of 150 m· s^-1 or higher. Silicate, germanate, and borate glasses were studied in order to clarify the importance of "anomalous" vs "normal" elastic characteristics on their impact behavior. As expected it was found that glasses in these systems which are "anomalous" showed impact behavior which had earlier been seen in silica and borosilicate glass, whiie those glasses which are "normal" showed behavior similar to that shown by soda-lime silica glass. On the other hand, although B₂O₃ has been characterized as "normal," its impact, as well as its quasi-static behavior, appears to put it in a class by itself. In this case, no cracking is observed during loading up to 150 m·s^-1, while radial and lateral cracking are seen during unloading.

"Host-guest" chemistry in the synthesis of ordered nonsiliceous mesoporous materials

On the basis of the consideration of "host-guest" chemistry, the interactions between guest molecules are highlighted in the synthesis of nonsiliceous mesoporous materials by the "soft-template" and "hard-template" approaches. A generalized "acid-base pair" concept is utilized in selecting appropriate guest molecules to prepare highly ordered mesoporous metal oxides, phosphates, and borates with diversified structures. Mesoscopically ordered polymer and carbon frameworks with uniformly large pore sizes are derived from the self-assembly of an organic surfactant with an organic guest. Properly building the guest unit and decorating the host are important in replicating ordered nonsiliceous single-crystal nanoarrays. Outlooks on the potential possibilities for synthesizing ordered mesoporous nonsiliceous materials are presented as well.

耐火材料文献中"In-Situ"一词的辨析

"In-Situ"一词在耐火材料的专业文献中出现较频.本文从发表的文献中摘录了一些使用"In-Situ"一词的例子,对其在不同场合使用的多种含义作了辨析.指出了其缺乏严谨定义的多义性.如何正确理解并译成中文,当视具体情况推敲而定.写文章时不宜滥用或刻意使用该词.     

炼油厂"三泥"处理研究与设计

通过对炼油厂污水处理场“三泥”性质的调查研究,认为必须经调质、沉降浓缩、絮凝等处理后再离心脱水,才能达到预期的效果。处理后的“三泥”,液相返回调节池,固相送到焚烧炉焚烧,焚烧后气体以CO2的形式排至大气,将污泥降解为无机物,彻底解决了污水处理的二次污染问题。
