Nonequilibrium Laser Regulation of the Electronic Structure of the Ni‐Based Electrode for Boosting Nucleophilic Electrooxidation of Alcohols

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This work reports an efficient, simple, low‐cost, and scalable method for overall electrode preparation. Nonequilibrium laser synthesis rapidly yields NiO nanocrystals on which a nickel oxyhydroxide (NiOOH) overlayer is grown in situ. By varying the number of laser pulses, the Ni3+/Ni2+ ratio is precisely tuned, thereby modulating the electronic ...

Fish Scales: A Multifunctional Biomaterial from Nature

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Fish scales demonstrate nature's solution to impact protection through overlapping multilayered architecture. This biological design combines mineralized surfaces with collagen networks to achieve both flexibility and fracture resistance. The structural principles inspire advanced protective materials and biomedical implants, where damage tolerance ...

Redistributing Cobalt and Tungsten From WC–Co Soft Scrap Toward Sustainable Cathode and Coating Materials for Lithium‐Ion Batteries

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A sustainable upcycling strategy transforms tungsten carbide–cobalt (WC–Co) soft scrap into high‐performance cathode materials. Recycled Co with trace nickel (Ni) is resynthesized into stabilized LiCoO2 with superior high‐voltage durability, while the recovered tungsten is further utilized as tungsten trioxide to enhance Ni‐rich cathode interfaces ...

Nanofiber PVA‐Based Membranes Incorporating Functionalized Spanish Broom Derivatives for Sustainable Water Purification

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study investigates Spanish broom (Spartium junceum) as a renewable source for electrospun composite membranes in sustainable water purification. MCC and biochar were functionalized with eco‐friendly precursors and nanomaterials (i.e., HNT, β‐CDs) to develop hybrid PVA nanofiber composites.
