Tuning Separator Chemistry: Improving Zn Anode Compatibility via Functionalized Chitin Nanofibers
Nanochitin derived from waste shrimp shells is used to fabricate separators for aqueous zinc batteries. By tuning the density of amine and carboxylic surface groups, water mobility at the separator interface is controlled, promoting uniform zinc deposition, suppressing dendrite growth, and enabling exceptional cycling stability exceeding 2000 h ...

Porous Ecoflex/PTFE composite with encapsulated liquid generates electricity through ionic migration induced by dynamic pore deformation, creating non‐uniform electric fields that drive charge induction on electrodes. This mechanism enhances charge transfer and ensures stable contact electrification performance, achieving 12 V and 4 nC with consistent ...

3D Printing Innovations in Polymeric Porous and Patterned Architecture
Polymeric foams occupy a unique structural space between dense solids and open networks, where engineered void fraction governs mechanical compliance, thermal resistance, and mass transport. Additive manufacturing now enables precise spatial control over cellular architecture, unlocking designer foam structures across applications spanning crash ...

We use scanning nitrogen vacancy magnetometry to directly image the weak in‐plane magnetic moments in mixed phase BiFeO3 at the nanoscale and quantify the local magnetic moments to be 18.8±2.0 μB/nm2 in the rhombohedral‐like phase and 1.5±0.6 μB/nm2 in the well‐known non‐magnetic tetragonal‐like phase.

A fluorenyl‐containing polyimine is introduced as a simple, scalable precursor for high‐performance carbon membranes. The precursor's intrinsic kinked structure enables defect‐free membrane formation with enhanced hydrogen permeance and excellent ideal selectivities for key industrial gas pairs (H2/N2, H2/CH4, and H2/CO2), offering a practical route ...

Solution‐processed Cu(bdc) forms prototypical MOF thin films for which a multitude of not fully satisfactory structural models have been suggested. Combining rotating grazing‐incidence diffraction and X‐ray reflectivity on two complementary samples with density‐functional theory, we first discard the previously suggested models and then identify a non ...

Thioketal (TK) polymers are promising biomaterials due to their selective biodegradation by reactive oxygen species (ROS), but they respond slowly to physiologic doses of ROS. Here, the TK bond's pendant groups are modified to enhance the degradation of TK‐based implants both in vitro and in vivo.
