Microenvironment‐Responsive Biomimetic Hydrogels Delivering Cistanche Deserticola‐Derived Nanovesicles for Intervertebral Disc Degeneration

Advanced Science, EarlyView.
An injectable, microenvironment‐responsive hydrogel (HAPOCS@CDNVs) is developed for sustained delivery of Cistanche deserticola‐derived nanovesicles (CDNVs). By scavenging ROS, restoring mitochondrial function, and attenuating SASP, this platform effectively suppresses nucleus pulposus cell senescence and facilitates extracellular matrix reconstruction,

Interpretation of \u3b1-Pinene Mass Spectra in APCI-Like Ambient Mass Spectrometry Using GC-Coupled Atmospheric Pressure Corona Discharge Ionization

Ambient mass spectrometry (AMS) enables real-time analysis without sample preparation, yet atmospheric pressure corona discharge ionization (APCI)-like ion sources can oxidize analytes in-source, obscuring spectral interpretation.

Interface‐Mediated Self‐Rectifying CsCuCl3 Memristors With Tunable Thresholds for Reconfigurable Neuromorphic Computing

Advanced Science, EarlyView.
Interface‐mediated CsCuCl3 memristors achieve self‐rectification and tunable thresholds, enabling selector‐free 8 × 8 arrays with > 105 ON/OFF and > 104 rectification. Supporting dual‐mode neuromorphic computing, negative thresholds preserve low‐light recognition accuracy (91%), while positive thresholds enable sparsity‐aware edge computing.

Solute‐Induced Modulation of Hydrogen Bonding, Ion Hydration, and Protonation in Hydrogels for Enhanced Microwave Absorption

Advanced Science, EarlyView.
Systematic solute screening reveals how noncovalent interactions regulate dielectric loss in P(AA‐co‐AM) hydrogels. By tuning proton conduction, ion hydration, and hydrogen‐bond interactions, the dielectric response can be precisely controlled, enabling tailored hydrogels with broadband microwave absorption and providing a general strategy for ...

Al1−xHfxN$\text{Al$_{1-x}$Hf$_{x}$N}$ Thin Films with Enhanced Piezoelectric Responses for GHz Surface Acoustic Wave Devices

Advanced Electronic Materials, EarlyView.
Reactively sputtered wurtzite Al1‐xHfxN thin films, exhibiting strong c‐axis texture and enhanced piezoelectric response, are demonstrated as a cost‐effective alternative to Al1‐xScxN. X‐ray absorption spectroscopy reveals that cross‐gap N 2p–Hf 5d hybridization increases the Born effective charge and enables a multifold increase in piezoelectric ...

Controlling Self‐Doping in Conjugated Polyelectrolyte Copolymers to Vary the Threshold Voltage in OECTs

Advanced Electronic Materials, EarlyView.
Two series of self‐doped conjugated polyelectrolytes are synthesized from a non‐self‐dopable building block 3MEEET and a self‐dopable building‐block 3HOT−[TMA+] or 3HOT−[SO3H] enabling precise control over the degree of self‐doping, which in turn directly governs the threshold voltage (VT) in OECTs over a wide range of 700 mV.
