High-performance water oxidation electrocatalysis enabled by a Ni-MOF nanosheet array

An Ni-MOF nanosheet array on Ni foam (Ni-MOF/NF) acts as a high-performance and durable electrocatalyst for the oxygen evolution reaction in 1.0 M KOH, needing an overpotential of 320 mV to drive 100 mA cm⁻².

Development of a L‐cysteine Sensor Based on Thallium Oxide Coupled Multi‐walled Carbon Nanotube Nanocomposites with Electrochemical Approach

Here, nanocomposites of thallium oxide doped multi-walled carbon nanotube (Tl₂ O MWCNT NCs) were prepared by utilizing a wet-chemical method (WCM) in an alkaline phase at low temperature. Different optical procedures (FTIR: Fourier Transform Infra-Red Spectroscopy, XRD: Powder X-ray diffraction, FESEM: Field-Emission Scanning Electron Microscopy, XEDS: X-ray Electron Dispersive Spectroscopy, TEM: Tunneling Electron Microscopy, and XPS: X-ray photoelectron spectroscopy) were used to fully characterize (optical, structural, crystalline, morphological, and elemental etc.) of the prepared Tl₂ O MWCNT NCs. Modification of the thin-layer with NCs onto glassy carbon electrode (GCE) is prepared and applied for the selective and sensitive enzyme-free detection of L-cysteine by an electrochemical approach. Using a reliable current-voltage approach, analytical sensing indexes such as sensitivity, LDR, LOD, LOQ, durability, and interference were assessed by fabricated sensor probe (GCE/Tl₂ O MWCNT NCs/CPM) in selective detection of L-cysteine at room temperature, whereas nafion was used as conducting polymer matrix (CPM) during the fabrication of GCE with NCs. L-cysteine calibration plot was found to be linear over an extensive range of concentration. The calibration curve was used to calculate the sensing parameters such as sensitivity (316.46 pAμM^-1 cm^-2 ), LOD down to (∼18.90±1.89 pM), and LOQ (63.0 pM) of the prepared sensor. The use of a simple WCM to validate the Tl₂ O.MWCNT NCs is a good approach for developing a NCs-based sensor for enzyme-free biomolecule identification and detection in the biomedical and health care fields in a broad scale. This proposed sensor (GCE/Tl₂ O MWCNT NCs/CPM) is used to detect selective L-cysteine in real biological samples such as human, mouse, and rabbit serum and found acceptable and satisfactory results.

Fabrication of selective and sensitive chemical sensor probe based on ternary nano-formulated CuO/MnO2/Gd2O3 spikes by hydrothermal approach

In this approach, thin spikes (NSs) of ternary nano-formulated mixed CuO/MnO₂/Gd₂O₃ were synthesized by the hydrothermal approach for efficient detection of 3-methoxyphenyl hydrazine (3-MPHyd) chemical from various environmental samples. The NSs were systematically characterized by using XPS, EDS, TEM, FTIR, UV/vis, and XRD. The fabricated NSs onto the glassy carbon electrode (GCE) was successfully applied for the selective and sensitive detection of 3-MPHyd in the phosphate buffer system (PBS), which displayed the highest sensitivity, good selectivity with ultra-trace detection limit, high stability, good reproducibility, and quick response time. The real environmental samples were tested for validation from stand point of the ternary doped nanomaterials for sensing in the practical applications using by electrochemical method.

2-[(1-Methyl-1<i>H</i>-pyrrol-2-yl)methylidene]propanedinitrile

In the title compound, C(9)H(7)N(3), the N-bound methyl group and vinyl H atom are syn. The 12 non-H atoms comprising the mol-ecule are essentially coplanar (r.m.s. deviation = 0.071 Å). Supra-molecular tapes feature in the crystal packing, orientated perpendicular to [10-1], and are formed by C-H⋯N inter-actions involving each cyano N atom. The tapes are connected into layers via π-π inter-actions occurring between translationally related pyrrole rings [ring centroid-centroid distance = 3.8754 (10) Å]; the layers stack along the b axis.
