بررسی عوامل مؤثر در بهبود خواص عملکردی و حساسیتی MOFهای پرانرژی (HE-MOF)

Authors

Abstract:

High Energy Density Materials (HEDMs) are a new generation of high-energetic materials with high-performance and safety and consist of several different types with different properties. One category of this kind of HEDMs explosives are high energy metal organic frameworks (HE-MOFs) that have more appropriate performance and safety compared to conventional explosives (HEMs) and even other HEDMs. These compounds consist of a metal ion (transition element) and high-energy ligands that are located in the metalchr(chr('39')39chr('39'))s coordination space. Various factors are involved in improving the performance and sensitivity of high energy metal organic frameworks (HE-MOFs). Factors such as type of structure, ligand,  central metal ion, molecular structure strain, and removal of trapped solvent in the network are affecting factors that enhance the performance. The parameters such as bond dissociation energy (BDE) inter/intra molecular interactions, free space in the crystalline network and encapsulated sensitive groups, are effective in reducing sensitivity and enhancing the safety of high energy metal organic frameworks. In this paper, the effective factors in the performance and sensitivity of HE-MOFs have been investigated.

کوکریستالیزاسیون مواد پرانرژی: از مهندسی مولکولی تا بهبود خواص

A Cocrystallization is an attractive molecular engineering approach for realizing improved energetic materials (explosives, propellants, and pyrotechnics). When two or more neutral species are combined to form a new structure, cocrystalline materials are created with distinct solid-state properties. As the performance criteria of energetic materials (explosive power, thermal stability, and phys...

بررسی خواص کیفی، عملکردی و زیست‌فعالی در گندم سن‌زده

باوجود تمام پیشرفت‌های حاصله در زمینۀ کنترل آفت‌ها، سن همچنان در اکثر مناطق کشت گندم ایران یک آفت خطرناک محسوب می‌شود. این حشره با هیدرولیز پروتئین‌ها توسط پروتئیناز بزاق خود باعث ایجاد خصوصیات ضعیف رئولوژیکی و تولید نان با حجم کم و بافت نامناسب می‌گردد. ازطرفی هیدرولیز پروتئین‌ها می‌تواند در بهبود خواص عملکردی، تولید پپتیدهای زیست‌فعال و بهبود سیستم فیزیولوژیک بدن نقش مؤثری داشته‌ باشد. در این...
