Friction is a more difficult stimulus to dissipate in comparison to impact. The desensitization method developed, is with minimal material manipulations. Practical considerations as mode of application, solubility, and controlling speed of gelation determine that the method of choice is a sol-gel process using a mixture of three alkylalkoxysilanes,<em>R<sub>n<\/sub><\/em>Si(O<em>R<\/em>\u2032)<sub>4\u2013<\/sub><em>n<\/em>, producing a hybrid organic-inorganic gel enabling complete triacetone triperoxide (TATP) desensitization at 20\u201325\u2009% v\/v concentrations.<\/p>\n<p>Weitz, A., Korogodsky, G., Tsoglin, A., Grinstein, D. and Gottlieb, L.
