Natural deep eutectic solvent for cellulose isolation from almond shell powder: A sustainable approach for by-product valorizationMendeley Data

Industrial Crops and Products
Cellulose was isolated from almond shell through different pretreatments: a conventional 7.5 % NaOH method and a natural deep eutectic solvent method using choline chloride:urea (2:1), both treatments carried out at 80 °C for 4 h.

An All‐Soft Wearable Electrochemiluminescence Chip for Sweat Metabolite Detection

Advanced Science, EarlyView.
A wearable electrochemiluminescence chip for sweat metabolite monitoring is pioneered, integrating “all‐soft” components: a flexible closed bipolar electrode (c‐BPE) array based on laser‐induced graphene (LIG), a laser‐cut microfluidic layer for sweat collection, and deep eutectic solvents (DES)‐based conductive ionogels for ECL emission.

EGaIn‐Activated Bioinspired Silk Micro/Nanofibril Eutectogels Breaking the Strength–Conductivity Trade‐Off for High‐Performance Wearable Bioelectronics

Advanced Science, EarlyView.
Inspired by the extracellular matrix, eutectogels are prepared by in situ deconstruction of silk fibroin into micro/nanofibrils and EGaIn‐induced polymerization. The multiscale fibril network with dynamic crosslinking achieves high strength (1.25 MPa), toughness (23.09 MJ m−3), and conductivity (1.51 S m−1), outperforming previous natural polymer ...
