泥页岩水敏性对盐岩层塑性变形的影响

由于处在盐岩层夹层中的泥页岩水敏性的影响,经24小时吸附水化和渗透水化后的泥页岩膨胀压力高达36.44MPa。抑制泥页岩水敏性是控制盐岩层塑性变形的有效途径。

eFeed-Hungers.com: Mitigating global hunger crisis using next generation technologies

Hunger is a global crisis and impacting the world for a very long time. Significant efforts have been made in the past by various organizations employing various means to address this persisting problem. Despite this, it still remains far from being resolved. Recently, the United Nations has published a report on global hunger, which claims that the global food production is fairly enough to feed the entire world with a population of about 7.3 billion. However, a major quantity of the food grown is not channeled appropriately and effectively to reach the needy and thus gets wasted unfortunately. Using the advanced computer technologies, we devise and develop a web-based computational framework (eFeed-Hungers.com) that serves as a bridge between the food waste and the hunger to mitigate the hunger issue; the food waste is the excess, unused, edible food, which otherwise is destined to the dumpster unfortunately. The eFeed-Hungers.com encourages and assists the food waste donation announcements with the least minimal efforts with the best possible outreach. Through the eFeed-Hungers.com, the food donations are globally searchable by the needy, with enough additional information imparted for quick decisions making to fetch the appropriate donated food. The eFeed-Hungers.com is envisioned to be a fully functional organization eventually with global outreach.     

Nitrosation and Nitration of Tetraacetyldibenzylhexaazaisowurtzitane

Tetraacetyldibenzylhitane (TADBIW) was subjected to debenzylation by nitrosating with inorganic materials available commercially to synthesize tetraacetyldinitrosohexaazaisowurtzitane (TADNSIW). TADNSIW was purified, and its structure was determined by FTIR, 1H NMR, MS and element analysis. The debenzylation reaction of TADBIW gave quantitative benzaldehyde as a by-product. This indicates that the reaction produces an imine cation as an intermediate. Hexanitrohexaazaisowurtzitane (HNIW) was prepared from unpurified TADNSIW with the yield over 96.0 % and the purity more than 98.0 %. And the mechanism of the reaction from TADNSIW to HNIW is proposed to be oxidation of nitroso and nitration of acetyl on the molecule of TADNSIW, This reaction system involved is simple, and the reaction can complete within a short time and under mild conditions. The product can be easily to separate and the waste disposed readily.     

报废“双迫”药改制射钉弹用球扁药新工艺研究

为了解决"双迫"型废火药的处理和再利用问题,提出了一种制备射钉弹用球扁型发射药的新工艺.工艺过程包括将经过粉碎的原料药粒分散到含有分散剂的水溶液中,加入适量的乙酸乙酯溶剂使药粒表层溶胀,在搅拌剪切力和界面张力的作用下,药粒的表面发生球形化转变,再经过洗涤、分级和烘干等处理,得到表面光滑的球扁药.研究得到的适宜工艺条件为溶剂比1.0～2.0 ml·g-1,用水量为药粒的6.0倍,分散剂用量为水量的1.0%～2.0%,搅拌速率500～600 r·min-1(线速度4.0～5.0 m·s-1),溶胀温度和时间分别为65～68 ℃和30 min.成品球扁药的堆积密度由0.70 g·cm-3提高到0.95 g·cm-3以上,流出时间由7.5 s下降到4.0 s以下.在射钉枪上进行测试,其主要弹道性能达到PATMI标准的规定指标.
