Chemical Characterisation of Steam‐Distilled Essential Oils From Lemongrass (Cymbopogon citratus Stapf) and Ginger Rhizomes (Zingiber officinale Roscoe) Using FTIR and GC‐MS: Comparison of Phytochemical Composition

Phytochemicals in Food and Medicine, Volume 1, Issue 4, December 2026.
Illustration of essential oil extraction coupled with characterisation. ABSTRACT Essential oils from lemongrass and ginger rhizomes contain bioactive compounds with potential for nutraceutical and pharmaceutical applications. In this study, essential oils were extracted from ginger rhizomes and lemongrass by the steam distillation method, using a ...

Core–Shell Molecularly Imprinted Polymer@SiO2@Fe3O4 for Low‐Cost and Selective Electrochemical Sensing of Paraquat

ChemElectroChem, Volume 13, Issue 21, 3 November 2026.
A low‐cost electrochemical sensor for paraquat (PQ) was developed by modifying a screen‐printed carbon electrode with a PQ‐selective core–shell molecularly imprinted polymer (MIP) synthesized via precipitation polymerization. Coupled with adsorptive stripping voltammetry (AdSV), the MIP‐modified sensor enables highly sensitive and selective detection ...

Joule self‐heating enabled oxygen transport and coupled methane reactions in a La0.6Sr0.4Co0.2Fe0.8O3‐δ hollow fiber membrane reactor

AIChE Journal, Volume 72, Issue 11, November 2026.
Abstract Mixed‐conducting ceramic hollow fiber membranes are a versatile platform for oxygen separation, value‐added chemical production, and oxy‐combustion. Because oxygen permeation is thermally activated, these systems typically rely on bulky, energy‐intensive furnaces that suffer from low efficiency and large thermal inertia.
