Liu, Zhenhua; Huang, Jinyu; Wang, Quan; Zhou, Jiaxi; Ye, Jiexiong; Li, Xuejin; Geng, Youfu; Liang, Zhiqiang; Du, Yu; Tian, Xiaoqing published the artcile< Indium oxide-black phosphorus composites for ultrasensitive nitrogen dioxide sensing at room temperature>, Related Products of 22519-64-8, the main research area is indium oxide black phosphorus composite ultrasensitive nitrogen dioxide sensing.

In2O3 nanorods were successfully incorporated by different amount of multi-layer black phosphorus (m-BP), forming the hetero-structured BP-In2O3 composites. The structure, morphol. and composition of the as-synthesized composites were characterized by X-ray diffraction (XRD), field-emission electron microscopy (FESEM), transmission electron microscopy (TEM) and XPS. Interestingly, the environmental stability of BP can be notably improved by the introduction of In2O3. Moreover, NO2 sensing properties of BP-In2O3 composites were tested at room temperature (25°C) with relative humidity of 30%. It is demonstrated that the sensor based on BP-In2O3 composites exhibits high response, lower detect limit, short response-recovery time and outstanding selectivity at room temperature Such sensing behavior can be attributed to high adsorption capacity to NO2, large surface area, excellent carrier mobility of BP-In2O3 in presence of BP, as well as high concentration of chemisorbed oxygen on the In2O3 surface derived from electrons transfer from BP to In2O3.

Ding, Yao; Wei, Dingqiong; He, Rong; Yuan, Rusheng; Xie, Tengfeng; Li, Zhaohui published the artcile< Rational design of Z-scheme PtS-ZnIn2S4/WO3-MnO2 for overall photo-catalytic water splitting under visible light>, Synthetic Route of 22519-64-8, the main research area is platinum zinc indium sulfide manganese oxide photocatalytic water splitting.

ZnIn2S4/WO3 nanocomposites, with ZnIn2S4 nanosheets loaded on WO3 nanorods, were synthesized by self-assembly of hexagonal ZnIn2S4 in the presence of preformed WO3·H2O nanoplates. PtS and MnO2, the co-catalysts for H2 and O2 evolution, resp., were selectively loaded on ZnIn2S4 and WO3 in the nanocomposites. The resultant PtS-ZnIn2S4/WO3-MnO2 nanocomposites show photocatalytic activity for overall water splitting to produce H2 and O2 under visible light. An optimum activity was achieved over 0.5%PtS-20%ZnIn2S4/WO3-3.0%MnO2, in which 5.94 μmol of H2 and 2.24 μmol O2 were evolved in 8 h. The apparent quantum yield (AQY) for H2 evolution was determined to be ca. 0.50% at 420 nm. The superior photocatalytic activity for overall water splitting over PtS-ZnIn2S4/WO3-MnO2 nanocomposites can be ascribed to an efficient coupling of photocatalytic water reduction over PtS-ZnIn2S4 and photocatalytic water oxidation over MnO2-WO3 via a Z-scheme charge transfer pathway. This study demonstrates a high potential of fabrication of the all-solid Z-scheme photocatalytic systems for overall water splitting.

Toja, E.; Gorini, C.; Zirotti, C.; Barzaghi, F.; Galliani, G. published the artcile< Amnesia-reversal activity of a series of 5-alkoxy-1-arylsulfonyl-2-pyrrolidinones>, Quality Control of 5335-40-0, the main research area is pyrrolidinone alkoxyarylsulfonyl preparation antiamnesic; alkoxyarylsulfonylpyrrolidinone preparation antiamnesic antihypoxic.

A series of 5-alkoxy-1-arylsulfonyl-2-pyrrolidinones were prepared by condensation of arylsulfonyl chlorides with 5-alkoxy-2-pyrrolidinones. Most compounds reversed electroconvulsive shock-induced amnesia in mice, showing the typical inverted U-shaped dose-response curve. The results for 58 compounds indicate that the potency is maximum when there is a 5-ethoxy group and progressively declines as the ether alkyl chain is either elongated or shortened. Substitution on the Ph ring or its replacement with heterocyclic rings or its hydrogenation decreases the activity. The most promising compounds, with anti-amnesic properties superior in many respects (greater potency, greater efficacy and broader active dose-range) to those of piracetam and antiracetam were further evaluated for reversing scopolamine-induced amnesia and for their antihypoxic activity. 5-Ethoxy-1-phenylsulfonyl-2-pyrrolidinone and 5-(1-methylethoxy)-1-[3-(trifluoromethyl)phenylsulfonyl]-2-pyrrolidinone were selected for further evaluation because of their potent anti-amnesic and/or antihypoxic activity.

Although it is well known that viologen radical cations can self-assemble into stacks or complexes on account of radical-radical pairing interactions, it has only recently been demonstrated that reduction of main-chain polyviologens integrated into hydrogel networks can trigger actuation. In these earlier examples, hydrogels comprising oligoethylene glycol-based polyviologens and poly(ethylene glycol) were functionalized with terminal azide groups to prepare ‘click’-based gels. Here, we report a new structural design for the functional polyviologen that consists of main-chain viologen subunits separated by hexamethylene groups instead of glycols and is capped at each end with styrene groups. Activation of this viologen-based macrocrosslinker was achieved using chem.- and photoreduction methods and its ability to undergo intramol. chain-folding was monitored by absorption spectroscopy. Acrylate-based organogels and hydrogels were also prepared and a comparison was carried out to assess the actuator performance in each gel in terms of the rate of contraction and changes in stiffness.

The orexin system is responsible for regulating the sleep-wake cycle. Suvorexant, a dual orexin receptor antagonist (DORA) is approved by the FDA for the treatment of insomnia disorders. Herein, we report the optimization efforts toward a DORA, where our starting point was (5-methoxy-4-methyl-2-[1,2,3]triazol-2-yl-phenyl)-{(S)-2-[5-(2-trifluoromethoxy-phenyl)-[1,2,4]oxadiazol-3-yl]-pyrrolidin-1-yl}methanone (6), a compound which emerged from our inhouse research program. Compound 6 was shown to be a potent, brain-penetrating DORA with in vivo efficacy similar to suvorexant in rats. However, shortcomings from low metabolic stability, high plasma protein binding (PPB), low brain free fraction (fu brain), and low aqueous solubility, were identified and hence, compound 6 was not an ideal candidate for further development. Our optimization efforts addressing the above-mentioned shortcomings resulted in the identification of (4-chloro-2-[1,2,3]triazol-2-yl-phenyl)-{(S)-2-methyl-2-[5-(2-trifluoromethoxy-phenyl)-4H-[1,2,4]triazol-3-yl]-pyrrolidin-1-yl}l-methanone (42), a DORA with improved in vivo efficacy compared to 6.
