He, Mengxue; Li, Xia; Holmes, Nathaniel Graham; Li, Ruying; Wang, Jiajun; Yin, Geping; Zuo, Pengjian; Sun, Xueliang published the artcile< Flame-Retardant and Polysulfide-Suppressed Ether-Based Electrolytes for High-Temperature Li-S Batteries>, Safety of (9Z,12Z)-Methyl octadeca-9,12-dienoate, the main research area is flame retardant ether electrolytes lithium sulfur battery; Li−S batteries; ether-based electrolyte; high temperature; inert diluter; nonflammable.

Lithium-sulfur (Li-S) batteries are drawing huge attention as attractive chem. power sources. However, traditional ether-based solvents (DME/DOL) suffer from safety issues at high temperatures and serious parasitic reactions occur between the Li metal anodes and soluble lithium polysulfides (LiPSs). Herein, we propose a polysulfide-suppressed and flame-retardant electrolyte operated at high temperatures by introducing an inert diluent 1,1,2,2-tetrafluoroethyl-2,2,3,3-tetrafluoropropyl (TTE) into the high-concentration electrolyte (HCE). Li dendrites are also efficiently suppressed by the formed LiF-rich protective layer. Furthermore, the shuttle effect is mitigated by the decreased solubility of LiPSs. At 60°C, Li-S batteries using this nonflammable ether-based electrolyte exhibit a high capacity of 666 mAh g-1 over 100 cycles at a current rate of 0.2C, showing the greatly improved high-temperature performance compared to batteries with traditional ether-based electrolytes. The improved electrochem. performance across a range of temperatures and the enhanced safety suggest that the electrolyte has a great practical prospect for safe Li-S batteries.

Yu, Wenbin; Zhao, Feiyang published the artcile< Prediction of critical properties of biodiesel fuels from FAMEs compositions using intelligent genetic algorithm-based back propagation neural network>, SDS of cas: 112-63-0, the main research area is biodiesel fatty acid methyl ester back propagation neural network.

In this study, an intelligent genetic algorithm (GA)-based back propagation neural network (BPNN) model was proposed to predict the properties of biodiesel fuels according to FAMEs compositions The hybrid BPNN-GA model has five inputs (Me palmitate, Me stearate, Me oleate, Me linoleate and Me linolenate) corresponding to the FAMEs compositions and outputs with estimated fuel properties, with the GA assisting on training to find out local min. deviation and updated weighting configurations. It was found that the intelligent learning-training method proposed hybrid BPNN-GA model enabled to map the non-linear relationships between the FAMEs compositions and key properties of biodiesel fuels with fairly good agreement. The predicted value of fuel properties agrees with measured ones with R-square up to 96%, along with lower value (less than 10%) over Root Mean Square Error (RMSE) and Mean Absolute Percentage Error (MAPE) than those of other empirical correlations. In addition, a sensitivity anal. was conducted to in-depth investigate the FAMEs compositions on key properties. It was concluded that saturated FAMEs have pos. impacts on CN, KV and the CFPP, while IV is typically dependent on unsaturated FAMEs. Therefore, it is attainable to formulate new types of alternative fuels based on the required properties on diesel engine applications.

Luminescent discotic liquid crystals based on tris(N-salicylideneaniline)s [TSANs] bearing trans-stilbene fluorophores have been synthesized. Their mesomorphic and photophys. properties were studied. These TSANs existing in the form of C3h and Cs geometrical isomers of the keto-enamine tautomer self-assemble to form the columnar phase and exhibit fluorescence both in solution and mesophase states. These columnar mesophases also exhibit frozen (glassy) columnar phase, which ensures preserved fluorescence intensity, defect free alignment and simultaneous restriction on the motion of ionic impurities. These features make them promising candidates for the use in organic light emitting diodes, particularly as emissive layers. This study also led to an understanding about the dependence of their mesomorphism (mesophase type, stability and thermal range) and photophys. features on the number and pattern of their peripheral substitution, in comparison to the analogous columnar liquid crystalline TSANs reported earlier.

Sun, Chaofeng; Peng, Fang; Li, Jianfei; Cui, Xudong; Qiao, Xin; Zhu, Wangliang published the artcile< Ferroptosis-specific inhibitor ferrostatin-1 relieves H2O2- induced redox imbalance in primary cardiomyocytes through the Nrf2/ARE pathway>, Application of C15H22N2O2, the main research area is ferrostatin 1 ferroptosis redox imbalance cardiomyocyte Nrf2 ARE pathway.

Ischemic heart disease (IHD) has always been the focus of attention of many researchers in cardiovascular disease, and its pathogenesis is also very complicated. Ferroptosis may be involved in the occurrence and development of IHD. First, primary cardiomyocytes were treated with H2O2 to simulate the IHD in vitro model. After pretreatment with different concentrations of ferrostatin-1, cell survival rate was detected by MTT method, cell apoptosis was detected by TUNEL staining and flow cytometry, and the expression of oxidative stress, ferroptosis, and related mols. of Nrf2/ARE pathway was detected by Western blotting (WB) and quant. real-time polymerase chain reaction (qRT-PCR). The mortality of primary cardiomyocytes in the H2O2 group was obviously increased. Ferrostatin-1 treatment can effectively inhibit cell death, improve antioxidant enzyme activity, inhibit the expression of ferroptosis-related mols., and activate Nrf2/ARE pathway expression. Ferroptosis-specific inhibitor ferrostatin-1 relieves H2O2-induced redox imbalance in primary cardiomyocytes through the Nrf2/ARE pathway, inhibits ferroptosis, and thereby slows cardiomyocyte death.

Qanash, Husam; Yahya, Reham; Bakri, Marwah M.; Bazaid, Abdulrahman S.; Qanash, Sultan; Shater, Abdullah F.; T. M., Abdelghany published the artcile< Anticancer, antioxidant, antiviral and antimicrobial activities of Kei Apple (Dovyalis caffra) fruit>, Formula: C19H34O2, the main research area is anticancer antioxidant antiviral antimicrobial Dovyalis fruit.

Secondary plant metabolites remain one of the key sources of therapeutic agents despite the development of new approaches for the discovery of medicinal drugs. In the current study, chem. anal., and biol. activities of Kei apple (Dovyalis caffra) methanolic extract were evaluated. Chem. anal. was performed using HPLC and GC-MS. Antiviral and anticancer effect were assessed using the crystal violet technique and activity against human liver cells (HepG2), resp. Antibacterial activity was tested with the disk diffusion method. The obtained results showed that chlorogenic acid (2107.96 ± 0.07 μg/g), catechin (168 ± 0.58 μg/g), and gallic acid (15.66 ± 0.02 μg/g) were the main bioactive compounds identified by HPLC techniques. While, compounds containing furan moieties, as well as levoglucosenone, isochiapin B, dotriacontane, 7-nonynoic acid and tert-hexadecanethiol, with different biol. activities were identified by GC-MS. Addnl., inhibition of 2,2-diphenyl-1-picryl-hydrazyl-hydrate (DPPH) scavenging was 79.25% at 2000 μg/mL, indicating its antioxidant activity with IC50 of 728.20 ± 1.04 μg/mL. The tested extract exhibited potential anticancer activity (58.90% toxicity) against HepG2 cells at 1000 μg/mL. Potential bacterial inhibition was observed mainly against Escherichia coli and Proteus vulgaris, followed by Staphylococcus aureus and Bacillus subtilis with a diameter of growth inhibition ranging from 13 to 24 mm. While weak activities were recorded for fungi Candida albicans (10 mm). The extract showed mild antiviral activity against human coronavirus 229E with a selective index (SI) of 10.4, but not against human H3N2 (SI of 0.67). The mol. docking study′s energy ratings were in good promise with the experiment documents of antibacterial and antiviral activities. The findings suggest that D. caffra juice extract is a potential candidate for further experiments to assess its use as potential alternative therapeutic agent.

Fragment screening collections were often predominantly populated with flat, 2D mols. A workflow for the design and synthesis of 56 3D disubstituted pyrrolidine and piperidine fragments that occupy under-represented areas of fragment space (as demonstrated by a principal moments of inertia (PMI) anal.) was described. A key, and unique, underpinning design feature of this fragment collection was that assessment of fragment shape and conformational diversity (by considering conformations up to 1.5 kcal mol-1 above the energy of the global min. energy conformer) was carried out prior to synthesis and was also used to select targets for synthesis. The 3D fragments were designed to contain suitable synthetic handles for future fragment elaboration. Finally, by comparing our 3D fragments with six com. libraries, it was clear that our collection was high three-dimensionality and shape diversity.
