Preliminary mechanistic insights into the detection of ethanol vapour using MnO NRs-CNPs-poly-4-(vinylpyridine) based solid-state sensor operating at room temperature.

Semiconductor metal oxide gas sensors are widely used to detect ethanol vapours, commonly used in industrial productions, road safety detection, and solvent production; however, they operate at extremely high temperatures. In this work, we present manganese dioxide nanorods (MnO NRs) prepared via hydrothermal synthetic route, carbon soot (CNPs) prepared via pyrolysis of lighthouse candle, and poly-4-vinylpyridine (P4VP) composite for the detection of ethanol vapour at room temperature. MnO, CNPs, P4VP, and MnO NRs-CNPs-P4VP composite were characterised using scanning electron microscopy, transmission electron microscopy, powder X-ray diffraction, Fourier transform infrared spectroscopy, and Raman spectroscopy.

Sodium alginate/carboxymethylcellulose gel formulations containing plant extract for wound healing.

Using appropriate wound dressings is crucial when treating burn wounds to promote accelerated healing. Sodium alginate (SA)-based gels containing Carboxymethyl cellulose (CMC) and Pluronic F127 were prepared. The formulations.

-Loaded Sodium Alginate Single- and Double-Layer Membrane Composites for Wound Healing.

: Effective wound dressing is the key solution to combating the increased death rate and prolonged hospital stay common to patients with wounds. : Sodium alginate-based single- and double-layer membranes incorporated with root extract were designed using the solvent-casting method from a combination of polyvinyl alcohol (PVA), Pluronic F127 (PF127), and gum acacia. : The successful preparation of the membranes and loading of the extract were confirmed using Fourier transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD).

Crystal structure of Staudtienic acid, a diterpenoid from Warb. (Myristicaceae).

This title compound, CHO, was isolated from the benzene fraction of the stem bark of Warb. (Myristicaceae) using column chromatography techniques over silica gel. The compound was fully characterized by single-crystal X-ray diffraction, one and two-dimensional NMR spectroscopy, IR and MS spectrometry.
