Biomimetic Ion‐Orchestrated Hierarchical Armored Hydrogel Coating for Robust and Multifunctional Surface Protection

Advanced Functional Materials, EarlyView.
Inspired by the skin‐toughening mechanism of marine sponges, an ion‐orchestrated structural engineering strategy is proposed to regulate the surface microstructure of hydrogel coatings, enabling the in situ formation of a robust armor layer that enhances mechanical integrity and provides multifunctional protection by suppressing fouling attachment and ...

Characteristics of Tool Vibration in Ultrasonic Vibration Cutting

Journal of the Japan Society of Precision Engineering, 1979
Characteristics of vibration has been analyzed with a model of lumped system for a tool used in ultrasonic vibration cutting. The analysis shows that the amplitude of the tool vibration during cutting declines not always constantly but catastrophically with increase of cutting force at some conditions because of existing unstable phenomena in the ...

Cold Quad‐Modal Nanocomplex for Precise and Quantitative In Vivo Stem Cell Tracking

Advanced Functional Materials, EarlyView.
Multimodal albumin–bismuth sulfide–superparamagnetic iron oxide (ABS) nanocomplexes are developed for stem cell tracking across four different imaging modalities: MRI, MPI, MSOT, and CT. Combining its flexibility with high sensitivity, this quad‐modal imaging agent enables a robust quantification of ABS‐labeled stem cells in vivo.

Enhancing Synaptic Plasticity and Multistate Retention of Organic Neuromorphic Devices Using Anion‐Excessive Gel Electrolyte

Advanced Functional Materials, EarlyView.
Anion‐excessive gel‐based organic synaptic transistors (AEG‐OSTs) that can maintain electrical neutrality are developed to enhance synaptic plasticity and multistate retention. Key improvement is attributed to the maintenance of electrical neutrality in the electrolyte even after electrochemical doping, which reduces the Coulombic force acting on ...
