Harnessing Phase Separation for the Development of High‐Performance Hydrogels

Advanced Science, EarlyView.
ABSTRACT Hydrogels are indispensable for the development of next‐generation bioelectronics, soft robotics, and biomedical devices, where their mechanical properties determine performance and reliability. Among strategies to enhance hydrogel mechanics, phase separation enables controlled heterogeneity resulting in gel networks that are reinforced by ...

Interface Wettability Transition‐Driven Drug Release and Dual‐Phase Functionalization in Implant Abutment

Advanced Science, EarlyView.
A temporally controlled drug release coating is developed for abutments using a superhydrophobic coating self‐assembled on mesoporous silica. This surface provides sequential functionality: initial contamination resistance through non‐wetting, followed by controlled drug release via wettability transition.

Constructing Seamless Interfaces for Ultrastable Flexible Supercapacitors

Advanced Science, EarlyView.
Seamless electrode/electrolyte and electrolyte/electrolyte interfaces with boosted interfacial toughness and adhesion are constructed by anchored interfacial polymerization and in situ polymerization, respectively. The achieved supercapacitor exhibits ultrahigh capacitance retention over 100,000 times of charge/discharge or folding deformation ...

Measurement and Analysis of Stick-Slip and High-Frequency Torsional Coupled Oscillations of Drill String

Shiyou jixie
The self-excited torsional oscillation of the drilling system can reduce the contact force between the bit and the formation or the relative velocity of the cutting force.To mitigate the impact of this mechanism,the torsional oscillation of the drill ...

Wireless, Adaptable and Fully Implantable Battery‐powered Devices for Optical Stimulation of the Spinal Cord in Small Rodents

Advanced Science, EarlyView.
Current technologies for spinal cord optogenetic stimulation rely on external power sources and face reliability constraints in freely behaving animals. Here, a fully implantable, battery‐powered optoelectronic device is introduced, enabling operation in any selected environment with wireless recharging for months‐long stimulation.

N‐Doping Activated Presodiation Enhances Sodium‐Ion Provision in Hard Carbon Anodes

Advanced Science, EarlyView.
Introducing pyrrolic‐N sites enables efficient presodiation and stronger PF6− capture, thus pre ‐ forming a robust inorganic‐rich SEI layer in hard carbon anodes. ABSTRACT Hard carbon (HC) is considered the most promising anode material for commercial sodium‐ion batteries (SIBs), yet it still faces critical challenges such as low initial Coulombic ...
