Coordination polymers (CPs) have recently emerged as a promising class of high energy materials useful for the synthesis tailored energetic materials. CPs shown potential to improve performance relative conventional organic with regard density, oxygen balance, sensitivity, and heat detonation. Thus far, variety linkers been applied, success has achieved across number structure classes including nitrogen-rich heterocycles azides. Here, current progress in field CPs, both from standpoint...
PMMA@IRMOF-3@MOF-5, a hybrid polymer–MOF composite, was produced through combination of core–shell and post-synthetic modification techniques. The architecture allows polymer chains to be tethered the outer shell selectively.
Abstract An unprecedented mode of reactivity Zn 4 O‐based metal–organic frameworks (MOFs) offers a straightforward and powerful approach to polymer‐hybridized porous solids. The concept is illustrated with the production MOF‐5‐polystyrene wherein polystyrene grafted uniformly distributed throughout MOF‐5 crystals after heating in pure styrene for 4–24 h. surface area content material can be fine‐tuned by controlling duration presence MOF‐5. Polystyrene grafting significantly alters physical...
Two energetic metal-organic frameworks (MOFs), Co-ANTA and Zn-ANTA, are synthesized from 5-amino-3-nitro-1H-1,2,4-triazole (ANTA) exhibit superior oxygen balance, density, thermal stability compared to ANTA. The balance is achieved through a combination of hydroxide ligands deprotonated linkers. Although the materials isostructural have similar sensitivity heat, their impact sensitivities significantly different. Similar ANTA, Zn-ANTA fairly insensitive impact. By contrast, ANTA increased...
Adsorption of oxidizing guest molecules into a non-energetic microporous coordination polymer produces explosives with desirable oxygen balance, high heat released upon decomposition, and suppressed vapor pressure the guest. Here, this results in primary explosives, materials very sensitive to impact, that have potential be used as replacements for lead-based initiators.
Simulations of CO2 sorption were performed in two members the highly tunable rht-metal–organic framework (MOF) platform: PCN-61 and PCN-66. These MOFs differ only triisophthalate ligand used to synthesize respective MOFs. In PCN-61, center contains a benzene ring; this ring is substituted with triphenylamine group There are chemically distinct Cu2+ ions that comprise copper paddlewheels, [Cu2(O2CR)4], all rht-MOFs. One type ion, denoted Cu1, projects into truncated tetrahedral (T–Td)...
Nitrated metal–organic frameworks transform into carbon structures with highly dispersed metal through a deflagration process involving extremely anisotropic reaction propagation.

AbstractThe presence of U and Th as impurities in zircon makes it radioactive. Provided the levels are below 500 ppm, or 70 Bq g-1 activity, limits that allow transportation material a non-radioactive substance, is acceptable commercial product. However, some sands contain radioactivity well above this limit. A new process (the pure process) described for removal from zircon. Tests to identify best flux addition, calcination temperature time, leaching conditions indicated by grinding sample...
A decomposed copper based metal–organic framework containing amorphous Cu species was found to be a highly reactive carbon supported catalyst (<bold>a-Cu@C</bold>).
Electrically conductive silicones have been used in applications including automotives, communications, and consumer electronics. These are expected to significantly grow with the evolving technologies autonomous driving, electrical vehicle, 5G ecosystem. Here we present two novel solventless electrically (one silver based, one nickel-coated graphite based) excellent conductive, shielding, adhesive performance designed for electromagnetic compatibility (EMC) as an adhesive, a form-inplace...
