Yang, Jie published the artcileSurface modification of core-shell structured ZIF-67@Cobalt coordination compound to improve the fire safety of biomass aerogel insulation materials, Quality Control of 1455-77-2, the main research area is zeolitic imidazolate framework cobalt coordination compound surface modification; biomass aerogel fire safety thermal insulation property.

Biomass materials are considered to be excellent candidates to replace petroleum-based materials, but inherent flammability limits their applications. In this work, biomass aerogel (BA) was prepared by freeze-drying method from sodium alginate (SA) and polyvinyl alc. (PVA). To improve fire safety of BAs, a core-shell structured ZIF-67@cobalt coordination compound was successfully synthesized, which was surface functionalized by 3,5-diamino-1,2,4-triazole and 9,10-dihydro-9-oxo-10-phospho-diphenyl-10-oxide (DOPO), named as DOPO-NH2-ZIF-67. The addition of DOPO-NH2-ZIF-67 (2 wt%) outstandingly improved fire safety of BA, in contrast to neat BA, peak heat release rate, peak smoke production rate, and total smoke production were reduced by 66.6%, 85.10%, and 72.76%, resp. Furthermore, the incorporation of ZIF-67 and its derivatives has no adverse effect on the thermal insulation performance of BA composites and significantly improved their compressive strength from 0.27 MPa to 1.76 MPa. Preparation of core-shell structured ZIFs rich in active groups furnishes a conceivable way to synthesize an effective flame retardant, and a prospective method for the fabrication of aerogel insulation materials with green and economical additive-free technol. is proposed.

Jia, Shuaiqiang published the artcileHierarchical Metal-Polymer Hybrids for Enhanced CO2 Electroreduction, HPLC of Formula: 1455-77-2, the main research area is hierarchical metal polymer hybrid carbon dioxide electroreduction; CO2 reduction reaction; electrochemistry; hierarchical structures; materials science; metal-polymer hybrids.

The design of catalysts with high activity, selectivity, and stability is key to the electroreduction of CO2. Herein, we report the synthesis of 3D hierarchical metal/polymer-carbon paper (M/polymer-CP) electrodes by in situ electrosynthesis. The 3D polymer layer on CP (polymer-CP) was first prepared by in situ electropolymerization, then a 3D metal layer was decorated on the polymer-CP to produce the M/polymer-CP electrode. Electrodes with different metals (e.g. Cu, Pd, Zn, Sn) and various polymers could be prepared by this method. The electrodes could efficiently reduce CO2 to desired products, such as C2H4, CO, and HCOOH, depending on the metal used. For example, C2H4 could be formed with a Faradaic efficiency of 59.4% and a c.d. of 30.2 mA cm-2 by using a very stable Cu/PANI-CP electrode in an H-type cell. Control experiments and theor. calculations showed that the 3D hierarchical structure of the metals and in situ formation of the electrodes are critical for the excellent performance.

Zhou, Shengren published the artcileStructure-Property Relationships of ETNC and Its Salts Compared with PETNC and Its Salts, Synthetic Route of 1455-77-2, the main research area is erythritol pentaerythritol tetranitrocarbamate salt structure property relationship.

Two energetic compounds, erythritol tetranitrocarbamate (ETNC) and pentaerythritol tetranitrocarbamate (PETNC), and their salts, were synthesized in three steps, characterized and compared. All synthesized compounds were characterized by IR, DSC and multinuclear NMR spectroscopy. Four compounds were further investigated by single crystal X-ray diffraction. All nonmetal salts show extremely low mech. sensitivity (IS�30 J; FS�360 N). The heats of formation were calculated using Gaussian 09, and the detonation performances were calculated using EXPLO 5. Although these nonmetal salts are lower than the neutral compounds ETNC (D: 7960 m s-1, P: 27.4 GPa) and PETNC (D: 7629 m s-1, P: 24.3 GPa), they possess high detonation performances that are better than TNT. Erythritol-based and corresponding pentaerythritol-based energetic materials were compared in terms of their thermostability, detonation velocity and detonation pressure. They were also compared in their resp. series. ETNC and PETNC and their salts have short preparation steps and are easy to isolate in high yields, and thus have promising potential applications as explosives.

Huang, Shiqi published the artcileSynthesis and combustion catalytic activity of ferrocene-based energetic compounds, HPLC of Formula: 1455-77-2, the main research area is combustion catalytic activity ferrocene based energetic compound crystallog.

Ammonium perchlorate (AP) is a common oxidizer in composite solid rocket propellants due to its excellent burning characteristics, good processability, and storability. Owing to their outstanding catalytic effects, ferrocene, and its derivatives have become the most widely used burning rate catalysts (BRCs). The addition of ferrocene and its derivatives to AP rendered performance optimization. In this study, azole-based ferrocenyl compounds were successfully synthesized. The compounds were characterized by single-crystal X-ray diffraction, UV-vis spectroscopy, and other techniques. The thermal degradation of AP catalyzed by these compounds was evaluated by differential scanning calorimetry and thermogravimetric anal. Results revealed that the decomposition peak temperature of AP dramatically decreases and that the released heat of AP significantly increases with the new compounds as additives. Hence, the six azole-based ferrocenyl BR catalysts are favorable for the combustion catalytic activity.

Six energetic salts based on fully nitroamino-functionalized fused-triazole were synthesized. All salts were characterized by IR, multinuclear NMR spectroscopy, thermal anal., and elemental anal. The crystal structures of the salts 2, 3, and 6 were confirmed by single-crystal X-ray diffraction. The densities of all salts lie in the range between 1.77-1.83 g cm-3, while their decomposition temperatures range within 142-200°. Most energetic salts are slightly more sensitive than RDX. The calculated detonation pressures and velocities (Gaussian 09 and EXPLO5) of salts 2-7 range within 21.7-39.3 Gpa and 7867-9401 m s-1, resp. Salt 7 exhibits a high d.
