Fish Scales: A Multifunctional Biomaterial from Nature

ENERGY &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 ...

Dual‐Mode Electrophoretic Displays Enabled by Quantum Dot‐Decorated PR48:2 Pigment Particles and TiO2 for All‐Weather Visibility, Excellent Bistability, and Enhanced Readability

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study presents a novel quantum dot electrophoretic display (QDEPD), which combines electro‐controlled reflection and optically‐triggered emission to achieve efficient multi‐modal switching within a single pixel. By incorporating multi‐component nanostructures, the system enhances functional integration and multi‐modal response capabilities.

Bridging Stability and Reactivity: Novel Dinucleating Ligand With Rigid Backbone Stabilizes a Cu2O2 Side‐On Peroxido Structure

European Journal of Inorganic Chemistry, EarlyView.
The herein‐developed tyrosinase model complex enables the transfer of tyrosinase‐like catalytic oxygenation activity into artificial systems. Therefore, it enables the use of molecular oxygen for oxygenation and oxidation of phenolic substrates at room temperature.

Layer Geometry Modulation in Cu(II) Coordination Networks Based on Disubstituted Bis(imidazolyl)benzene Ligands

European Journal of Inorganic Chemistry, EarlyView.
Cu(II)‐based two‐dimensional coordination networks constructed from bis(imidazolyl)benzene ligands show how subtle changes in counteranion identity modulate layer geometry, stacking, and stability. Single‐crystal structures combined with bulk syntheses reveal distinct packing efficiencies and framework responses to humidity, vacuum, and temperature for

Lipid‐based Nano‐delivery systems as a promising strategy for the treatment of epilepsy: Current status and challenges

Epilepsia Open, EarlyView.
Abstract Objective Epilepsy is a prevalent chronic neurological disorder characterized by abnormal neuronal electrical activity. The primary treatment modality for individuals with epilepsy (PWE) is antiseizure medication (ASM). The multiple potential factors contributing to treatment resistance in epilepsy may be attributed to the inability of ASMs to
