Peptide Assembly of Al/CuO Nanothermite for Enhanced Reactivity of Nanoaluminum Particles

Biological self-assembly procedures, which are generally carried out in an aqueous solution, have been found to be the most promising method for directing the fabrication of diverse nanothermites, including Al/CuO nanothermite. However, the aqueous environment in which Al nanoparticles self-assemble has an impact on their stability. We show that using a peptide to self-assemble Al or CuO nanoparticles considerably improves their durability in phosphate buffer aqueous solution, with Al and CuO nanoparticles remaining intact in aqueous solution for over 2 weeks with minimal changes in the structure. When peptide-assembled Al/CuO nanothermite was compared with a physically mixed sample in phosphate buffer for 30 min, the energy release of the former was higher by 26%. Furthermore, the energy release of peptide-assembled Al/CuO nanocomposite in phosphate buffer showed a 6% reduction by Day 7, while that of the peptide-assembled Al/CuO nanocomposite in ultrapure water was reduced by 75%. Taken together, our study provides an easy method for keeping the thermal activity of Al/CuO nanothermite assembled in aqueous solution.

制氢装置水分器三通开裂原因分析

分析了某炼油厂制氢装置水分器三通的腐蚀开裂原因,认为在高温工况时,失效构件的高温蒸汽腐蚀诱发的应力腐蚀占主导地位,它破坏了不锈钢表面氧化膜的保护性并产生腐蚀微裂纹,冲刷和气蚀及二氧化碳腐蚀起加剧作用;在低温工况时,氢致开裂占主导地位,进一步使裂纹扩展直至开裂;各种腐蚀形式交互影响,加剧了水分器三通的腐蚀开裂失效。通过工艺流程动改,取消了三通部件,彻底消除了该部位存在的腐蚀开裂隐患。
