Li, Zengxing; Ng, Kim Hoong; Xu, Shen; Zhang, Yingzhen; Lei, Yonggang; Huang, Jianying; Lai, Yuekun published the artcile< Facile preparation of tremella-like TiO2/Cd:ZnIn2S4 photoanode with enhanced photo-electro-chemical (PEC) performance for energy and environmental applications>, Recommanded Product: Indium(III) chloride tetrahydrate, the main research area is titanium oxide cadmium zinc indium sulfate nanocomposite photoanode; Photoanode; Photoelectrochemical; TiO(2) nanotubes; ZnIn(2)S(4).

The realization of solar-driven photoelectrochem. (PEC) process lies in the success development of materials with excellent photoelec. properties. Past reports identified TiO2, upon modified with both Cd and ZnIn2S4 (ZIS), exhibits promising PEC performance; however, at the cost of tedious preparation In view of this, our work proposes a facile one-step hydrothermal strategy to deposit both modifiers onto the pre-obtained TiO2 nanotubes (NTs), realizing rose-like TiO2/ZnIn2S4 (TiO2/ZIS) or tremella-like TiO2/Cd:ZnIn2S4 (TiO2/Cd:ZIS) with improved PEC performances. Interestingly, the thickness of ZIS petals, which deposited on top of TiO2 NTs, is pos.-correlated to its Cd-composition, signifying the substitutional doping of Cd into the unit cell of ZIS. This renders robust ionic interactions between the constituents, prompting the enhanced optical properties of TiO2 in conjecture to its reduced impedance. As a result, the recombination rate of photo-elec.-derived carriers was drastically suppressed, with an improved photocurrent d. of 606.2μA cm-2 recorded by TiO2/Cd:ZIS photoanode under solar irradiation Such performance is 80 times and 5.16 times higher than those of bare TiO2 NTs and TiO2/ZIS counterparts. The photoconversion efficiencies in terms of incident photon-to-current conversion efficiency (IPCE) and applied bias photon current efficiency (ABPE) for TiO2/Cd:ZIS were significantly improved too, recorded at 1.12% and 0.38%, resp., under standard evaluation condition. As summary, our work proposes a facile one-step hydrothermal approach that simultaneously-deposit both Cd and ZIS onto TiO2 photoanode for an enhanced PEC performance. This opens up a wider horizon for PEC technol., further unlocking its potential in both energy and environmental applications.

Kovalcik, Thomas R.; Guillory, J. Keith published the artcile< The stability of cyclophosphamide in lyophilized cakes. Part I. Mannitol, lactose, and sodium bicarbonate as excipients>, COA of Formula: C7H17Cl2N2O3P, the main research area is cyclophosphamide stability lyophilization; mannitol cyclophosphamide stability lyophilization; lactose cyclophosphamide stability lyophilization; bicarbonate cyclophosphamide stability lyophilization.

Lyophilized products containing cyclophosphamide (I) and one of the following excipients: mannitol, lactose, NaHCO3, or sorbitol, were prepared All of the products were well-formed cakes with the exception of the one containing I and sorbitol, which was a collapsed mass. I in lyophilized cakes containing mannitol, lactose, or NaHCO3 undergo rapid (t90 ≈ 15 days) degradation in the solid state. A simple method was developed which permits introduction of measured quantities of water vapor into the lyophilized cake. In the cakes containing mannitol or NaHCO3 as adjuvants, DSC and x-ray diffraction showed that I was converted from the amorphous to the monohydrate form when exposed to moisture, and exhibited improved stability. In the case of the cake containing lactose, the lactose, but not the I, was converted to a monohydrate, and the stability of I was not improved.

El Nady, Jehan; Ali, Magdy; Kamel, Ola A.; Ebrahim, Shaker; Soliman, Moataz published the artcile< Room temperature synthesis of aqueous ZnCuInS/ZnS quantum dots>, Electric Literature of 22519-64-8, the main research area is zinc sulfide quantum dot room temperature.

In this work a new method was developed for synthesis of aqueous cadmium-free, CuInS (CIS) quantum dots (QDs) at room temperature CIS QDs as cores were alloyed with 25% of Zn2+ ions at room temperature and followed by the growth of ZnS shell to form CIS and ZCIS QDs. X-ray diffraction (XRD) anal. confirmed that the ZCIS QDs have a wurtzite structure. Moreover, the energy-dispersive X-ray (EDX) anal. demonstrated that ZCIS QDs are composed of Cu, In, Zn and S elements. It was found that Zn ions introduced into CIS QDs lattice structure did not change in the crystal structure. ZCIS/ZnS QDs showed high photoluminescence (PL) peak and its position and intensity depend on the Cu:In ratio. High resolution transmission electron microscope (HRTEM) images showed that ZCIS and ZCIS/ZnS QDs have a spherical shape with average diameter sizes of 4.0 nm and 7.0 nm, resp. The selected area electron diffraction (SAED) suggested that the prepared ZCIS QDs are crystalline with an interplanar distance of 0.320 nm.

Yi, Xiaofeng; Wang, Di; Li, Fan; Zhang, Jian; Zhang, Lei published the artcile< Molecular bixbyite-like In12-oxo clusters with tunable functionalization sites for lithography patterning applications>, Recommanded Product: Indium(III) chloride tetrahydrate, the main research area is indium oxo cluster mol bixbyite lithog patterning application.

Indium oxides have been widely applied in many technol. areas, but their utilization in lithog. has not been developed. Herein, we illustrated a family of unprecedented In12-oxo clusters with a general formula [In12(Μ4-O)4(Μ2-OH)2(OCH2CH2NHCH2CH2O)2(OR)4X4]X2 (where X = Cl or Br; R = CH3, C6H4NO2 or C6H4F), which not only present the largest size record in the family of indium-oxo clusters (InOCs), but also feature the first mol. model of bixbyite-type In2O3. Moreover, through the labile coordination sites of the robust diethanolamine-stabilized In12-oxo core, these InOCs can be accurately functionalized with different halides and alc. or phenol derivatives, producing tunable solubility Based on the high solution stability as confirmed by ESI-MS anal., homogeneous films can be fabricated using these In12-oxo clusters by the spin-coating method, which can be further used for electron beam lithog. (EBL) patterning studies. Accordingly, the above structural regulations have significantly influenced their corresponding film quality and patterning performance, with bromide or p-nitrophenol functionalized In12-oxo clusters displaying better performance of sub-50 nm lines. Thus, the here developed bixbyite-type In12-oxo cluster starts the research on indium-based patterning materials and provides a new platform for future lithog. radiation mechanism studies.

Yang, Yang; Ohnoutek, Lukas; Ajmal, Saira; Zheng, Xiuzhen; Feng, Yiqing; Li, Kejian; Wang, Tao; Deng, Yue; Liu, Yangyang; Xu, Dong; Valev, Ventsislav K.; Zhang, Liwu published the artcile< ""Hot edges"" in an inverse opal structure enable efficient CO2 electrochemical reduction and sensitive in situ Raman characterization>, COA of Formula: Cl3H8InO4, the main research area is carbon dioxide electrochem reduction sensitivity inverse opal structure.

Conversion of CO2 into fuels and chems. via electroreduction has attracted significant interest. Via mesostructure design to tune the elec. field distribution in the electrode, it is demonstrated that the Cu-In alloy with an inverse opal (CI-1-IO) structure provides efficient electrochem. CO2 reduction and allows for sensitive detection of the CO2 reduction intermediates via surface-enhanced Raman scattering. The significant enhancement of Raman signals of the intermediates on the CI-1-IO surface can be attributed to elec. field enhancement on the “”hot edges”” of the inverse opal structure. Addnl., a highest CO2 reduction faradaic efficiency (FE) of 92% (sum of formate and CO) is achieved at -0.6 V vs. RHE on the CI-1-IO electrode. The diffuse reflectance IR Fourier transform spectroscopy (DRIFTS) results show that the Cu-In alloy with an inverse opal structure has faster adsorption kinetics and higher adsorption capacity for CO2. The “”hot edges”” of the bowl-like structure concentrate elec. fields, due to the high curvature, and also concentrate K+ on the active sites, which can lower the energy barrier of the CO2 reduction reaction. This research provides new insight into the design of materials for efficient CO2 conversion and the detection of intermediates during the CO2 reduction process.

Xu, Yan; Wang, Zhenbo; Ding, Caifeng; Luo, Xiliang published the artcile< Ratiometric antifouling electrochemiluminescence biosensor based on bi-functional peptides and low toxic quantum dots>, Recommanded Product: Indium(III) chloride tetrahydrate, the main research area is quantum dot peptide antifouling electrochemiluminescence biosensor.

It is a great challenge to detect the target selectively and accurately in complex biol. samples. A ratiometric signal amplification strategy based on antifouling peptide is proposed to detect thrombin (TB) in this work. The electrode is modified with conducting polymer poly(3,4-ethylenedioxythiophene) (PEDOT) and Au@Luminol. Then the bi-functional peptide anchors to the modified electrode and captures the low toxic electrochemiluminescence (ECL) probe. The bi-functional peptide includes a new antifouling sequence (DRDRDRDR) and a TB recognizable sequence (SGRPVLG), while the former can greatly reduce the non-specific adsorption in complex samples and the latter can be cleaved by TB. The new self-enhanced luminescence probe labeled as PAMAM-QDs is composed of low toxic and water-soluble CuInZnS/ZnS quantum dots (CIZS/ZnS QDs) and polyamidoamine (PAMAM) via amide bonds. Concentration of TB can be obtained via the ratio of the signals of ECLQDs/ECLAu@Luminol accurately and sensitively. The ECL biosensor with the detection line 1.82 fM can work from 10 fM to 1 nM. Thanks to the antifouling property of the designed peptide and the amplification of the new ECL probe, the biosensor can be used for quantifying TB in practical complex samples with high selectivity and sensitivity.

Harmsen, S.; Meijerman, I.; Beijnen, J. H.; Schellens, J. H. M. published the artcile< Nuclear receptor mediated induction of cytochrome P450 3A4 by anticancer drugs: a key role for the pregnane X receptor>, Name: 2-(Bis(2-chloroethyl)amino)-1,3,2-oxazaphosphinane 2-oxide hydrate, the main research area is pregnane X receptor cytochrome P450 3A4 colon adenocarcinoma anticancer.

Induction of cytochrome P 450 (CYP) 3A4, an enzyme that is involved in the biotransformation of more than 50% of all drugs, by xenobiotics is an important cause of pharmacokinetic drug-drug interactions in oncol. In addition to rifampicin and hyperforin, the anticancer drug paclitaxel has also been shown to be an inducer of CYP3A4 via activation of the pregnane X receptor (PXR). We therefore screened 18 widely used anticancer drugs for their ability to activate PXR-mediated CYP3A4 induction. A CYP3A4 reporter gene assay was employed to identify PXR agonists among the eighteen anticancer drugs. Subsequently CYP3A4 mRNA and protein expression following treatment with these PXR agonists was assessed. Finally, the effect of pre-treatment with these agents on the 1′-hydroxylation of midazolam (a specific CYP3A4 probe) was determined Paclitaxel, erlotinib, tamoxifen, ifosfamide, flutamide and docetaxel are able to activate PXR, while only strong PXR activation leads to significant induction of CYP3A4 activity. The identified PXR agonists may have the propensity to cause clin. relevant drug-drug interactions as a result of CYP3A4 induction.

Tang, Sheng; Li, Yu-Huan; Cheng, Xin-Yue; Li, Ying-Hong; Wang, Hui-Qiang; Kong, Lan-Ying; Zhang, Xin; Jiang, Jian-Dong; Song, Dan-Qing published the artcile< SAR evolution and discovery of benzenesulfonyl matrinanes as a novel class of potential coxsakievirus inhibitors>, Formula: C7H7ClO4S2, the main research area is benzenesulfonyl matrinane coxsakievirus inhibitor structure activity relationship; coxsackieviruse; druggability; matrinane; matrinic acid; structure–activity relationship.

Materials & methods: Fifty-one novel 12N-substituted matrinic acid derivatives were synthesized and evaluated for their anti-coxsackievirus B3 activities. Results: Structure-activity relationship studies revealed that the 11-side chain could be determinant for the selectivity index by adjusting overall lipophilicity, and 11-butane was the best one for both potency and druggability. The optimized 35d showed the broad-spectrum anti-coxsackieviruse effects, an excellent pharmacokinetics and a good safety profile. More importantly, it displayed a potential effect for the pleconaril-resistant coxsackievirus B3 as well. Its mode of action is targeting on the viral transcription and translation stage, a different mechanism from that of pleconaril. Conclusion: Thus, we considered that 35d is a promising anti-enteroviral candidate for the treatment of various diseases infected with coxsackieviruses.

Liu, Lin; Liu, Jiaqing; Yang, Weijie; Wan, Jun; Fu, Feng; Wang, Danjun published the artcile< Constructing a Z-scheme ZnIn2S4-S/CNTs/RP nanocomposite with modulated energy band alignment for enhanced photocatalytic hydrogen evolution>, Application of Cl3H8InO4, the main research area is zinc indium sulfide carbon red phosphorus photocatalytic hydrogen evolution; Energy band alignment; Nanocomposite; Photocatalytic hydrogen evolution; Red phosphorus; Sulfur vacancies.

Energy band structures greatly determine the charge separation and transfer properties in heterojunction photocatalysts and consequently their photocatalytic activities. Herein, a well-designed Z-scheme ZnIn2S4-S/CNTs/RP (ZIS-S/CNTs/RP) nanocomposite was fabricated according to an energy band alignment steering strategy to realize superior photocatalytic H2 evolution performance. The ZIS-S/CNTs/RP nanocomposite shows an efficient photocatalytic H2 evolution rate of 1639.9μmol g-1h-1, which is noticeably higher than that of pristine red phosphorus (RP) and CNTs/RP and ZIS-S/RP composites, as well as those of the compared heterojunctions using bulk RP or ZnIn2S4. Owing to the modification of nanosized RP and the introduction of sulfur vacancies in ZnIn2S2, a tailored energy band alignment of the heterojunction with a higher reduction potential and larger Fermi level p.d. was achieved, which resulted in significantly increased photogenerated electron-hole separation efficiency and a more efficient Z-scheme charge transfer mechanism, thus promoting the photocatalytic activity of ZIS-S/CNTs/RP. This work aims to provide a novel effective strategy for the construction of high-performance heterojunction photocatalysts by energy band engineering.
