The development of novel non-noble electrocatalysts with controlled structure and surface composition is critical for efficient electrochem. hydrogen evolution reaction (HER). Herein, the rational design of porous molybdenum carbide (β-Mo2C) spheres with different surface engineered structures (Co doping, Mo vacancies generation, and coexistence of Co doping and Mo vacancies) is performed to enhance the HER performance over the β-Mo2C-based catalyst surface. D. functional theory calculations and exptl. results reveal that the synergistic effect of Co doping with Mo vacancies increases the electron d. around the Fermi-level and modulates the d band center of β-Mo2C so that the strength of the Mo-H bond is reasonably optimized, thus leading to an enhanced HER kinetics. As expected, the optimized Co50-Mo2C-12 with porous structure displays a low overpotential (η10 = 125 mV), low-onset overpotential (ηonset = 27 mV), and high exchange c.d. (j0 = 0.178 mA cm-2). Furthermore, this strategy is also successfully extended to develop other effective metal (e.g., Fe and Ni) doped β-Mo2C electrocatalyst, indicating that it is a universal strategy for the rational design of highly efficient metal carbide-based HER catalysts and beyond.

In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Probing Sulfur Chemical and Electronic Structure with Experimental Observation and Quantitative Theoretical Prediction of Kα and Valence-to-Core Kβ X-ray Emission Spectroscopy, published in 2020-07-02, which mentions a compound: 4556-23-4, Name is Pyridine-4-thiol, Molecular C5H5NS, HPLC of Formula: 4556-23-4.

An extensive exptl. and theor. study of the Kα and Kβ high-resolution X-ray emission spectroscopy (XES) of sulfur-bearing systems is presented. This study encompasses a wide range of organic and inorganic compounds, including numerous exptl. spectra from both prior published work and new measurements. Employing a linear-response time-dependent d. functional theory (LR-TDDFT) approach, strong quant. agreement is found in the calculation of energy shifts of the core-to-core Kα as well as the full range of spectral features in the valence-to-core Kβ spectrum. The ability to accurately calculate the sulfur Kα energy shift supports the use of sulfur Kα XES as a bulk-sensitive tool for assessing sulfur speciation. The fine structure of the sulfur Kβ spectrum, in conjunction with the theor. results, is shown to be sensitive to the local electronic structure including effects of symmetry, ligand type and number, and, in the case of organosulfur compounds, to the nature of the bonded organic moiety. This agreement between theory and experiment, augmented by the potential for high-access XES measurements with the latest generation of laboratory-based spectrometers, demonstrates the possibility of broad anal. use of XES for sulfur and nearby third-row elements. The effective solution of the forward problem, i.e., successful prediction of detailed spectra from known mol. structure, also suggests future use of supervised machine learning approaches to exptl. inference, as has seen recent interest for interpretation of X-ray absorption near-edge structure (XANES).

Author is Meng, Xian-Shuang; Bai, Hua; Zhang, Qing; Lv, Qing; Chen, Yun-Xia; Ma, Hui-Juan; Li, Jing-Rui; Ma, Qiang.

A sensitive and reliable anal. method based on HPLC/MS/MS has been developed for the simultaneous determination of 15 nitroimidazoles in cosmetics. A diversity of cosmetic samples, including powder, lotion, shampoo, and cream were collected. The samples were ultrasonically extracted with aqueous methanol, and the extracts were then subjected to cleanup by SPE using an Oasis HLB cartridge followed by filtration with a 0.20 μm membrane filter. Afterwards, chromatog. separation was performed on an XSelect CSH C18 column (2.1 × 150 mm, 3.5 μm) maintained at 30°C within 15 min by a gradient of acetonitrile-0.1% aqueous formic acid solution at a flow rate of 0.25 mL/min. The mass spectrometric detection was carried out using electrospray pos. ionization under the multiple reaction monitoring mode. A good linearity was observed over the concentration range from 0.5 to 500 ng/mL. The intraday and interday precisions, which were investigated by determining all target compounds in cosmetics seven times/day and on 7 consecutive days, were below 5.00%. The mean recoveries at three spiked levels ranged from 80.42 to 100.83% with the RSDs from 0.45 to 9.02%. The LOQs were determined to be between 0.01 and 0.1 mg/kg. The method was sufficiently rapid, reliable, and sensitive for the determination of 15 nitroimidazoles in cosmetics.

A compound: 128717-77-1, is researched, SMILESS is O=C(C1=CNC2=C1C=CC=C2OC)O, Molecular C10H9NO3Journal, Article, Research Support, Non-U.S. Gov’t, Journal of Medicinal Chemistry called Development and Profiling of Inverse Agonist Tools for the Neuroprotective Transcription Factor Nurr1, Author is Zaienne, Daniel; Willems, Sabine; Schierle, Simone; Heering, Jan; Merk, Daniel, the main research direction is inverse agonist neuroprotective transcription factor Nurr1.Electric Literature of C10H9NO3.

The ligand-sensing transcription factor nuclear receptor related 1 (Nurr1) evolves as an appealing target to treat neurodegenerative diseases. Despite its therapeutic potential observed in various rodent models, potent modulators for Nurr1 are lacking as pharmacol. tools. Here, we report the structure-activity relationship and systematic optimization of indole-based inverse Nurr1 agonists. Optimized analogs decreased the receptor’s intrinsic transcriptional activity by up to more than 90% and revealed preference for inhibiting Nurr1 monomer activity. In orthogonal cell-free settings, we detected displacement of NCoRs and disruption of the Nurr1 homodimer as mol. modes of action. The inverse Nurr1 agonists reduced the expression of Nurr1-regulated genes in T98G cells, and treatment with an inverse Nurr1 agonist mimicked the effect of Nurr1 silencing on interleukin-6 release from LPS-stimulated human astrocytes. The indole-based inverse Nurr1 agonists valuably extend the toolbox of Nurr1 modulators to further probe the role of Nurr1 in neuroinflammation, cancer, and beyond.

Product Details of 4556-23-4. Aromatic compounds can be divided into two categories: single heterocycles and fused heterocycles. Compound: Pyridine-4-thiol, is researched, Molecular C5H5NS, CAS is 4556-23-4, about Efficient Raman Enhancement in Molybdenum Disulfide by Tuning the Interlayer Spacing. Author is Li, Xuanhua; Guo, Shaohui; Su, Jie; Ren, Xingang; Fang, Zheyu.

Two-dimensional nanomaterials, such as graphene and molybdenum disulfide (MoS2), have recently attracted widespread attention as surface-enhanced Raman scattering (SERS) substrates. However, their SERS enhancement is of a smaller magnitude than that of noble metal nanomaterials, and therefore, the detection sensitivity still needs to be substantially improved for practical applications. Here, we present the first detailed studies on the effect of the (MoS2) interlayer distances on the SERS intensity enhancement. We find that MoS2 with smaller interlayer distances achieves an SERS enhancement factor as high as 5.31 x 105, which is one of the highest enhancement factors to date among the two-dimensional nanomaterial SERS sensors. This remarkable SERS sensitivity is attributed to the highly efficient charge transfer from MoS2 to probe mols. The charge-transfer ability directly determines the variable quantity dz2 orbitals of Mo elements in the MoS2-mol. system and then tunes the Raman intensity of probe mols. Our work contributes to reveal the influence of MoS2 interlayer spacing on SERS detection and to open a new way for designing a highly sensitive nonmetal SERS technol.
