Author is Mohammadikish, Maryam; Yarahmadi, Sana.

Preparation, characterization, and catalytic properties of bimetallic coordination polymer constructed from 2-aminoterephthalic acid as linker, zinc cations as node, and cis-dioxo molybdenum units as catalytic active sites are reported via two pathways. Molybdenum centers were placed in N,O positions created by condensation reaction of 2-aminoterephthalic acid with salicylaldehyde while zinc cations coordinated via carboxylic acid groups of linker to achieve infinite chains of metalo-ligand. The obtained coordination polymer was fully characterized and its catalytic properties in the epoxidation of olefins with tert-Bu hydroperoxide (TBHP) described. In comparison with previously reported heterogenized molybdenum catalysts, this new coordination polymer exhibited good conversion as well as high selectivity in the epoxidation of olefins. The catalyst is stable under ambient conditions and could be reused as active catalyst for at least five times.

The chemical properties of alicyclic heterocycles are similar to those of the corresponding chain compounds. Compound: Pyridine-4-thiol, is researched, Molecular C5H5NS, CAS is 4556-23-4, about Electron-enriched thione enables strong Pb-S interaction for stabilizing high quality CsPbI3 perovskite films with low-temperature processing, the main research direction is caesium lead iodide perovskite thin film crystallization fabrication.COA of Formula: C5H5NS.

Cesium lead iodide (CsPbI3) perovskite is a promising photovoltaic material with a suitable bandgap and high thermal stability. However, it involves complicated phase transitions, and black-phase CsPbI3 is mostly formed and stabilized at high temperatures (200-360°C), making its practical application challenging. Here, for the first time, we have demonstrated a feasible route for growing high quality black-phase CsPbI3 thin films under mild conditions by using a neutral mol. additive of 4(1H)-pyridinethione (4-PT). The resulting CsPbI3 thin films are morphol. uniform and phase stable under ambient conditions, consisting of micron-sized grains with oriented crystal stacking. With a range of characterization experiments on intermol. interactions, the electron-enriched thione group in 4-PT is distinguished to be critical to enabling a strong Pb-S interaction, which not only influences the crystallization paths, but also stabilizes the black-phase CsPbI3via crystal surface functionalization. The 4-PT based CsPbI3 achieves 13.88% power conversion efficiency in a p-i-n structured device architecture, and encapsulated devices can retain over 85% of their initial efficiencies after 20 days of storage in an ambient environment, which are the best results among fully low-temperature processed CsPbI3 photovoltaics.

Integrating machine learning with surface-enhanced Raman scattering (SERS) accelerates the development of practical sensing devices. Such integration, in combination with direct detection or indirect analyte capturing strategies, is key to achieving high predictive accuracies even in complex matrixes. However, in-depth understanding of spectral variations arising from specific chem. interactions is essential to prevent model overfit. Herein, we design a machine-learning-driven “”SERS taster”” to simultaneously harness useful vibrational information from multiple receptors for enhanced multiplex profiling of five wine flavor mols. at parts-per-million levels. Our receptors employ numerous noncovalent interactions to capture chem. functionalities within flavor mols. By strategically combining all receptor-flavor SERS spectra, we construct comprehensive “”SERS superprofiles”” for predictive analytics using chemometrics. We elucidate crucial mol.-level interactions in flavor identification and further demonstrate the differentiation of primary, secondary, and tertiary alc. functionalities. Our SERS taster also achieves perfect accuracies in multiplex flavor quantification in an artificial wine matrix.

The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: Bis(acetylacetonato)dioxomolybdenum(VI)( cas:17524-05-9 ) is researched.Computed Properties of C10H14MoO6.Polo, Annalisa; Nomellini, Chiara; Grigioni, Ivan; Dozzi, Maria Vittoria; Selli, Elena published the article 《Effective Visible Light Exploitation by Copper Molybdo-tungstate Photoanodes》 about this compound( cas:17524-05-9 ) in ACS Applied Energy Materials. Keywords: copper molybdenum tungstate photoanode light exploitation. Let’s learn more about this compound (cas:17524-05-9).

The need for stable oxide-based semiconductors with a narrow band gap, able to maximize the exploitation of the visible light portion of the solar spectrum, is a challenging issue for photoelectrocatalytic (PEC) applications. In the present work, CuW1-xMoxO4 (Eg = 2.0 eV for x = 0.5), which exhibits a significantly reduced optical band gap Eg compared with isostructural CuWO4 (Eg = 2.3 eV), was investigated as a photoactive material for the preparation of photoanodes. CuW0.5Mo0.5O4 electrodes with different thicknesses (80-530 nm), prepared by a simple solution-based process in the form of multilayer films, effectively exhibit visible light photoactivity up to 650 nm (i.e., extended compared with CuWO4 photoanodes prepared by the same way). Furthermore, the systematic investigation on the effects on photoactivity of the CuW0.5Mo0.5O4 layer thickness evidenced that long-wavelength photons can better be exploited by thicker electrodes. PEC measurements in the presence of NaNO2, acting as a suitable hole scavenger ensuring enhanced photocurrent generation compared with that of water oxidation while minimizing dark currents, allowed us to elucidate the role that molybdenum incorporation plays on the charge separation efficiency in the bulk and on the charge injection efficiency at the photoanode surface. The adopted Mo for W substitution increases the visible light photoactivity of copper tungstate toward improved exploitation and storage of visible light into chem. energy via photoelectrocatalysis.
