Bio‐Compatible Flexible Memristive Devices Enabled by BNNT/MWCNT–ZnO Quantum Dot Hybrid Percolation Networks

Small, EarlyView.
BNNT rods incorporated into MWCNT–ZnO quantum dot networks regulate charge transport and suppress leakage in flexible, transparent resistive memory devices. The resulting hybrid architecture preserves nonvolatile switching under static bending and after low‐temperature exposure and subcutaneous implantation.

Oppositely Charged Homopolypeptides Form Ordered Helix Assemblies With Hierarchical Structure

Small, EarlyView.
Hexagaonal and square assembly of polyarginine alfa‐helices formed in highly ordered polyarginine/polyaspartic acid complexes. The helices exhibit additional periodic staggering along their helical axis. ABSTRACT Oppositely charged polyelectrolytes are known to form polyelectrolyte complexes.

Unraveling the Proton‐Induced Degradation Mechanism in Quantum‐Dots Light‐Emitting Diode for Space Applications

Small, EarlyView.
Low‐energy proton irradiation induces ligand detachment at the QD/ZnO interface in quantum‐dot light‐emitting diodes (QLEDs). The exposed ZnS surface interacts with ZnO defects, generating a high density of interfacial trap states that promote electron trapping, suppress charge injection, and accelerate non‐radiative recombination, ultimately leading ...
