Thermoresponsive Soft and Self‐Anchoring Cuff Electrode for Chronic Peripheral Interfaces

Advanced Functional Materials, EarlyView.
A novel thermoresponsive, soft and self‐anchoring (TSSA) cuff electrode utilizing shape memory polymers achieves autonomous, sutureless peripheral nerve fixation. Driven by thermally induced pre‐strain and tissue adhesion, the device self‐closes and softens at body temperature, successfully minimizing mechanical mismatch. This adaptive platform ensures

Crystal Growth Engineering for Dendrite‐Free Zinc Metal Plating

Advanced Materials, EarlyView.
This research employed the rare‐earth ion dysprosium (Dy) to modulate aqueous zinc (Zn) metal plating. Integrated multiscale experiments and computational modeling unveiled the preferential adsorption of Dy on specific crystal facets, which activated screw dislocation‐driven Zn growth.

Electrochemical Impedance Spectroscopy Investigation of Alloy Inconel 718 in Molten Salts at High Temperature

International Journal of Electrochemical Science, 2011
The corrosion behavior in molten salts of Inconel 718 (IN 718) superalloy was investigated by Electrochemical Impedance Spectroscopy (EIS). The corrosion test temperatures used were salt melting points of Na2SO4, 80V2O5-20Na2SO4, NaVO3 and natural ash ...

POM‐Based Water Splitting Catalyst Under Acid Conditions Driven by Its Assembly on Carbon Nanotubes

Advanced Materials, EarlyView.
A newly‐engineered POM‐based electrocatalyst incorporating non‐innocent counter cations exhibits fast kinetics for either the OER or HER under strongly acidic conditions (1 m H2SO4), depending on whether it is assembled on carbon nanotubes (1@CNT) or physically mixed with them (1/CNT). In water‐splitting tests using a two‐electrode setup, these systems

Electrochemical Behavior and Corrosion Of Iron Crystals in Ammonium Nitrate Solutions

Corrosion, 1964
Single crystals of iron produced by strainanneal method and whiskers obtained by reduction of ferrous chloride with hydrogen were investigated as regards the stationary corrosion potential, cathodic and anodic polarization, general corrosion, and stress corrosion cracking in 5 N ammonium nitrate solution. The results reveal intergranular
