A P/N-containing flame retardant (PPT) constructed by phosphaphenanthrene, phosphonate, and triazole groups was successfully synthesized and used as a reactive co-curing agent for epoxy resin (EP). The curing behavior, thermal property, combustion behavior, and flame retardant mechanism of EP thermosets were comprehensively investigated. According to the analysis of DSC and TGA, PPT accelerated the crosslinking reaction and enhanced the charring ability for EP thermosets at high temperature. The results of combustion test indicated that PPT endowed epoxy thermoset with outstanding flame retardancy. When the phosphorus content was 0.71 wt%, EP/DDS/PPT-2 achieved a LOI value of 33.2% and passed V-0 rating in UL-94 test, and its peak heat release rate and total heat release were decreased by 63.7 and 30.5%, respectively, relative to EP/DDS. Moreover, the FIGRA of EP/DDS/PPT-2 was reduced from 9.7 to 3.5 kW m(-2) s(-1), manifesting the significantly improved fire safety of EP thermoset. The flame retardant mechanism was summarized as two parts: (a) the barrier effect of continuous phosphorus-rich char layers in condensed phase, (b) the quenching effect of phosphorous radicals and diluting effect of nonflammable gases in gaseous phase.

Due to the disadvantages of lower tensile strength and fracture toughness, the widely application of Ethylene-propylene-diene-monomer rubber (EPDM) has been limited. In this study, a thermally reversible healing EPDM based elastomer with H-bonding and Zn-based-bonding dynamic cross-link network was prepared. The influence of mole ratio of ATA/MAH on tensile strength and fracture energy of mEPDM(0)-xATA was investigated. The results showed that increasing the content of ATA brings about a gradual improvement in tensile strength of the mEPDM(0)-xATA. Especially when the mole ratio of ATA/MAH is 1, the fracture energy of mEPDM(0)-ATA is dramatically enhanced to 33.9 MJ/m(3), which is best among the ratios studied in our research. After curing, the effect of ZnCl(2)content on tensile strength and fracture energy of mEPDM-ATA-nZn was also studied. Meanwhile, the uniaxial cyclic loading-unloading tensile test was used to study the viscous damping properties of mEPDM-ATA-0.4Zn, which showed reversible repair properties after heat treatment. The results of dynamic rheological measurement showed that the damping properties were improved.

Type 1 diabetes (T1D) results in decreased oocyte quality and compromised early embryonic development. Procyanidin B2 (PB2) is a natural compound extracted from grape seeds and has strong antioxidant activity in vivo. This study evaluated the effect of PB2 on oocyte maturation in diabetic mice. Diabetic mice were induced by streptozotocin (STZ) injection. PB2 was supplemented in the in vitro maturation medium, and the ratio of germinal vesicle breakdown (GVBD) and polar body extrusion (PBE), reactive oxygen species (ROS) levels, mitochondrial function, developmental ability, as well as crotonylation at H4K5 were determined in oocytes. PB2 can promote the extrusion of PBE (88.34% vs. 75.02%,P < 0.05); reduce the generation of ROS (1.12 vs. 1.96,P < 0.05); and improve the level of mitochondrial membrane potential (0.87 vs. 0.79 Delta phi m,P < 0.05), ATP level (1.31 vs. 0.71 pmol,P < 0.05), and mitochondria temperature (618.25 vs. 697.39 pixels,P < 0.05). The addition of PB2 also improved the level of oocyte crotonylation at H4K5 (crH4K5) (47.26 vs. 59.68 pixels,P < 0.05) and increased the blastocyst rate (61.51% vs. 36.07%,P < 0.05) after parthenogenetic activation. Our results are the first to reveal a role for PB2 in promoting the viability of oocytes by regulating the mitochondrial function. Moreover, we uncover that PB2 can improve the level of crH4K5, which provides a new strategy to combat the decline in oocyte quality of diabetic. Recommanded Product: 61-82-5.

In order to design a new energetic material with desirable performance, it is necessary to know its detonation performance. This study, exhibits a linear relationship between detonation velocity of energetic cocrystals and their molecular structure through quantitative structure property relationship (QSPR) method. The methodology of this research affords a new model which can relate the detonation velocity of energetic cocrystals to their several molecular structural descriptors. Moreover, this method supposes that the detonation velocity of energetic cocrystals is a function of n(N), Mw, n(C)/n(H), and n(O)/n(H). The new correlation is acquired on the basis of calculated data of detonation velocities of 40 cocrystals through reliable methods as training set. The R-2 or determination coefficient of the obtained correlation is 0.952. The new correlatoion provides an appropriate estimation for further 12 energetic cocrystals as test set. Meanwhile, the root mean square and average absolute deviation of a newly introduced correlation were found to be 0.398 and 0.308 km center dot s(-1), respectively. As a matter of fact, it is conceivable to design novel energetic cocrystals by the utility of the proposed correlation.

In this work, (Z)-N-benzoyl-N ‘-(1H-1,2,4-triazol-3-yl)carbamimidothioic acid and its Mn(II), Co(II), Cu(II) and Cd(II) complexes were introduced for the first time. This carbonyl thiourea ligand was prepared by the reaction of 1H-1,2,4-triazol-3-amine with benzoyl isothiocyanate. The structural elucidation of these compounds was performed using elemental analysis and spectral and magnetic measurements. Octahedral structures of all complexes, except Cd(II) complex with a tetrahedral geometry, were confirmed by applying DFT structural optimization. The thermal decomposition behaviour of metal complexes of carbonyl thiourea ligand is discussed. The calculation of kinetic parameters for prepared complexes (E-a, A, Delta H*, Delta S* and Delta G*) of all thermal degradation stages has been evaluated using two comparable approaches. Antimicrobial and ABTS-antioxidant studies indicated potent activity of Cd(II) complex compared with the other investigated compounds. The cytotoxic activity of the prepared compounds was investigated in vitro. The results indicated potent activity of Mn(II) complex against both HePG2 (liver carcinoma) and MCF-7 (breast carcinoma) cancer cells.

Oxidative stress biomarkers are powerful endpoints in toxicological research. Cellular reductive/oxidative balance affects numerous signaling pathways involving H2O2. Detoxification and control of H2O2 levels results mainly from catalase activity. The aim of this work was to develop a precise, simple, cost-effective microassay to measure catalase activity in small tissue samples and cell extracts. We developed a protocol that quantifies H2O2 decomposition by intrinsic catalase in biological samples. Catalase activity was calculated based on rate of decomposition of H2O2, following absorbance at 240 nm. We developed a multi-well spectroscopic approach, reducing sample quantity requirements and allowing simultaneous assessment of large number of samples. The protocol is sensitive across a wide range of catalase activity (11.5-7575 U). The assay presents a 95% confidence interval with an intra-assay coefficient of variation of 3.7%, an inter-assay coefficient of variation of 6.2% and good correlation with a commercial kit. The assay was established and validated for different biological samples, including sheep hepatic tissue and human tumor and non-tumor cell lines. This high-throughput method is robust, sensitive, time-saving and cost-effective, generating highly reproducible results with precision and good correlation with a commercial kit reinforcing the method’s validity for research and toxicological applications.

This study investigated the nutrient content and reuse potential of wastewater generated during hydrothermal liquefaction of microalgal biomass. The hydrothermal liquefaction reaction was tested at 270, 300, 330, and 345 degrees C to determine the effect of temperature on the formation of non-biodegradable dissolved organic nitrogen (nbDON). Total nitrogen, ammonium, color, and toxicity were selected as key characteristics for the reuse of hydrothermal liquefaction wastewater. Results indicated that a higher concentration of nbDON(5) (nbDON defined with a 5 day growth assay) and more diverse heterocyclic N-containing organic compounds were associated with greater toxicity as measured by a growth rate assay. For the tested temperature ranges, the total nitrogen content of the hydrothermal liquefaction wastewater slightly decreased from 5020 +/- 690 mg L-1 to 4160 +/- 120 mg L-1, but the % nbDON(5) fraction increased from 57 +/- 3 %DON to 96 +/- 5 %DON. The temperature of hydrothermal liquefaction reactions can be optimized to maximize carbon conversion and nitrogen recovery. (C) 2019 Elsevier Ltd. All rights reserved.
