Yang, Qianqian published the artcileSolvent-Free Synthesis of N-Doped Porous Carbons from Chitosan for an Efficient CO2 Capture, Synthetic Route of 1455-77-2, the main research area is nitrogen doping carbon chitosan carbon dioxide adsorption.

A facile solvent-free strategy for constructing N-doped porous carbons (NPCs) by direct carbonization of chitosan with fully mixed N-sources is developed in this study. Carbonization temperatures and different N sources were thoroughly investigated to optimize the preparation conditions for better synthesis. Porosities and heteroatom doping (N doping) were comprehensively studied to figure out the effects on the CO2-uptake capacities of the NPCs. The obtained NPCs were fully characterized using different anal. techniques to explore their physicochem. properties and application potential. NPCs are found to perform greatly in porosities; In particular, NPCs prepared by grinding chitosan with 2,4,6-triaminopyrimidine followed by carbonization at 700°C exhibit CO2 adsorption capacities of 4.74 mmol g-1 (0°C and 1 bar). The abovementioned great CO2-uptake capacities as well as economical precursors and low energy demand indicate these chitosan-based NPCs to be promising industrial CO2-capture adsorbents.

Liu, Mingsheng published the artcileAn efficient anti-flaming phosphorus-containing guanazole derivative for cotton fabric, Category: isoquinoline, the main research area is guanazole flaming phosphorus cotton fabric.

A high-efficiency, halogen-free flame retardant: ammonium salt of guanazole-penta-(methylphosphonic acid) (AGPMPA) was synthesized in water solution under a mild reaction condition. The chem. structure of AGPMPA was characterized by FT-IR, 1H NMR, 13C NMR and 31P NMR spectra. Vertical burning tests showed that cotton fabrics treated with 20%, 25% and 30% AGPMPA cannot be ignited, and the shortest carbon length reaches 2.9 cm for 30% treated cotton. The limiting oxygen indexes of the treated cottons go up to 43.7-47.9% with the increases of AGPMPA concentrations and are still beyond 26.8% even after 50 laundering cycles, indicating that AGPMPA is a superior, durable flame retardant. Simultaneously, cone calorimeter data indicate that the heat release rate and the total heat release of treated cotton was remarkably decreased compared with those of control cotton. The TG-IR results indicate that the amounts of volatile products are prominently reduced, and the degradation temperature of treated cotton is lower than that of control cotton. The residual amounts of 46.1% in N2 gas and 31.6% in air for treated cotton fabric were attained, resp. No noteworthy change for the surface of treated cotton fiber was observed by SEM. The mech. properties of cotton fabrics before and after treatment have barely changed. These results proved that eco-friendly AGPMPA is an effective anti-flaming agent and has excellent durability.

Wang, Hao published the artcileHigh performance epoxy resin composites modified with multifunctional thiophene/phosphaphenanthrene-based flame retardant: Excellent flame retardance, strong mechanical property and high transparency, Synthetic Route of 1455-77-2, the main research area is thiophene phosphaphenanthrene flame retardant epoxy resin composite mech property.

It is always a challenge to prepare multifunctional epoxy resins (EP) composites with excellent flame retardance, mech. property and high transparency. In this work, a reactive flame-retardant (BDO) was synthesized from DOPO, 3,5-diamino-triazolz and thiophene-2-formaldehyde, and taken to prepare EP/BDO composites. Surprisingly, benefitting from the synergy of efficient flame retardant unit (DOPO structure), catalytic curing unit (triazole structure) and optical functional structure (thiophene-2-formaldehyde), the EP composites with excellent comprehensive performance was obtained. In detailed, after adding only 5 wt% BDO, the EP composites passed the UL-94 V-0 level, and the limiting oxygen index was increased to 33% from 22.5% of neat EP. At the same time, EP/BDO-5 showed obvious heat suppression and smoke suppression effects. Besides, EP/BDO-5 presented excellent mech. strength, that the tensile strength and bending strength were increased by 25% and 30% compared with neat EP. Moreover, EP/BDO composites maintained the same good light transmittance as neat EP, and also presented enhanced Tg and dielec. property. In addition, the dual phase flame-retardant mechanism was revealed through systematically analyzing residues after combustion and the gaseous phase products of flame retardant. The above results indicated EP/BDO composites with excellent comprehensive performance possessed a great potential application in high-performance composites fields.

Li, Changxia published the artcileCovalent Organic Framework (COF) Derived Ni-N-C Catalysts for Electrochemical CO2 Reduction: Unraveling Fundamental Kinetic and Structural Parameters of the Active Sites, HPLC of Formula: 1455-77-2, the main research area is covalent organic framework carbon dioxide electrochem reduction catalyst; Active Site Density; CO2 Reduction; Covalent Organic Framework; Single-Site Ni-N-C; Turnover Frequency.

Electrochem. CO2 reduction is a potential approach to convert CO2 into valuable chems. using electricity as feedstock. Abundant and affordable catalyst materials are needed to upscale this process in a sustainable manner. Nickel-nitrogen-doped carbon (Ni-N-C) is an efficient catalyst for CO2 reduction to CO, and the single-site Ni-Nx motif is believed to be the active site. However, critical metrics for its catalytic activity, such as active site d. and intrinsic turnover frequency, so far lack systematic discussion. In this work, we prepared a set of covalent organic framework (COF)-derived Ni-N-C catalysts, for which the Ni-Nx content could be adjusted by the pyrolysis temperature The combination of high-angle annular dark-field scanning transmission electron microscopy and extended X-ray absorption fine structure evidenced the presence of Ni single-sites, and quant. X-ray photoemission addressed the relation between active site d. and turnover frequency.

A series of novel energetic salts of 2,4,6-trinitropyridin-3-ol have been prepared and confirmed structurally. These compounds can be prepared by means of a facile synthetic procedure and show outstanding properties (detonation velocity, detonation pressure, sensitivity toward mech. stimuli, and temperature of decomposition). They were isolated and characterized by means of elemental anal., multinuclear (1H, 13C) NMR spectroscopy. The structures in the crystalline state were determined by single-crystal X-ray diffraction at 296 K. From the calculated standard molar enthalpy of formation (CBS-4 M) and the densities, the Chapman-Jouguet detonation properties were predicted by using the EXPLO5 V6.02 thermochem. computer code. Their sensitivities towards impact and friction were also determined
