Aqueous zinc-ion batteries (AZIBs) stand out among many energy storage systems due to their many merits, and it's expected to become an alternative to the prevailing alkali metal ion batteries. Nevertheless, the cumbersome manufacturing process and the high cost of conventional separators make them unfavorable for large-scale applications. Herein, inspired by the unique nature of cellulose and ZrO, a Janus cellulose fiber (CF)/polyvinyl alcohol (PVA)/ZrO separator is prepared via the vacuum filtration method. The interwoven cellulose fibers offer robust mechanical strength, which prevents dendrites from penetrating through the separator, while ZrO nanoparticles with Maxwell-Wagner effect regulate electric field and effectively promote uniform nucleation. Density functional theory (DFT) reveal CF/PVA/ZrO separator's ability to manipulate Zn deposition orientation to Zn (002), resulting in a dendrite-free, compact, and flat anode. Consequently, the obtained Zn||Zn symmetric cell exhibits superior electrochemical performance, able to operate at 1 mA cm for more than 1500 h and 6 mA cm for 400 h. In addition, CF/PVA/ZrO separator outperforms the commercially available glass fiber (GF) separator and CF separator when assembled into full cells using either polyaniline (PANI)@carbon nanotube (CNT) or MnO@CNT as cathode material. This work serves as a reference for the subsequent research in high performance AZIBs.

Developing cost-effective and environmentally sustainable active packaging materials remains an important challenge. We have developed rice bran protein (RBP)-based fibers incorporating carboxymethyl cellulose (CMC) and ZrO nanoparticles (ZrO NPs, 0 %-7 %, m/m) using microfluidic spinning. The integration of RBP, CMC, and ZrO NPs formed a robust hydrogen bond network that enhanced the fibers' thermal stability and crystallinity, reduced surface hydrophobicity, and aligned the molecular orientation.

Since petroleum became depleted, rapid attention has been devoted to renewable energy sources such as lignocellulosic biomass to produce useful chemicals for industry (for instance vanillin). Three primary components of lignocellulose are lignin, cellulose, and hemicellulose. This paper uses microwave-assisted technology to oxidize the kenaf stalk (lignocellulosic biomass) and extract lignin to produce vanillin.

Timely and rapid detection of antibiotic residues in the environment is conducive to safeguarding human health and promoting an ecological virtuous cycle. A foldable paper-based photoelectrochemical (PEC) sensor was successfully developed for the detection of ampicillin (AMP) based on glutathione/zirconium dioxide hollow nanorods/aptamer (GSH@ZrO HS@apt) modified cellulose paper as a reactive zone with laser direct-writing lead sulfide/cadmium sulfide/graphene (PbS/CdS/LIG) as photoelectrode and cobalt hydroxide (CoOOH) as a photoresist material. Initially, AMP was introduced into the paper-based reaction zone as a biogate aptamer, which specifically recognized the target and then left the ZrO HS surface, releasing glutathione (GSH) encapsulated inside.

The utilization of lignin, an abundant and renewable bio-aromatic source, is of significant importance. In this study, lignin oxidation was examined at different temperatures with zirconium oxide (ZrO)-supported nickel (Ni), cobalt (Co) and bimetallic Ni-Co metal catalysts under different solvents and oxygen pressure. Non-catalytic oxidation reaction produced maximum bio-oil (35.
