Dissolution of cellulose with ionic liquids allows the comprehensive utilization by combining two major green chemistry principles: using environmentally preferable solvents and bio-renewable feed-stocks. In this paper, dissolution its application were reviewed. Cellulose can be dissolved, without derivation, in some hydrophilic liquids, such as 1-butyl-3-methylimidazolium chloride (BMIMCl) 1-allyl-3-methylimidazolium (AMIMCl). Microwave heating significantly accelerates process. easily...

Glutathione (GSH) is a tripeptide and natural reducing agent composed of glutamic acid, glycine, cysteine. Its level in the human body closely linked to health, such as diabetes, Alzheimer's disease, cancer. The supplementation exogenous GSH could bring health benefits detection food considerable importance. However, existing assays for high-performance liquid chromatography/mass spectrometry, electrochemiluminescence fluorescent nanoprobe were not satisfactory because disadvantages...

Abstract Soft magnetic nanocrystalline alloys are technically crucial in power electronics, whereas confront the traded‐off between high saturation flux density ( B s ) and low coercivity H c due to incorporation of non‐magnetic elements or harsh crystallization process. To tackle this challenge, deep supercooling solidification strong immiscibility system employed prepare Fe 86 Si 1.3 9 C 2 Cu 1.7 alloy with superior softness. Benefitting from synergistically enhanced glass‐forming ability...

Abstract External magnetic fields emerge as a promising method for enhancing the electrocatalytic oxygen evolution reaction (OER), yet underlying magneto‐electric (ME) mechanisms are not well understood. The slow kinetics of OER make it key challenge in water‐splitting, technique sustainable H 2 fuel production. Herein, systematic approach is presented to analyzing ME governing OER, using metallic‐plate (Ni foam, Ni sheet, and Pt sheet) powder‐based (Co 3 O 4 /BaFe 12 19 on carbon paper)...
