Biological neural systems seamlessly integrate perception and action, a feat not efficiently replicated in current physically separated designs of neural-imitating electronics. This segregation hinders coordination and functionality within the neuromorphic system. Here, we present a flexible device tailored for neuromorphic computation and muscle actuation.

We report a Tuning Fork Scanning Electrochemical Cell Microscopy (TF-SECCM) technique for providing morphological and electrochemical information on single redox-active entities. This new operation configuration of SECCM utilizes an electrolyte-filled nanopipette tip mounted onto a tuning fork force sensor to obtain a precise tip-sample distance control and surface morphological mapping capabilities. Redox activities of regions of interest (ROIs) can be investigated by scanning electrode potential by moving the nanopipette to any target regions while maintaining the constant force engagement of the tip with the sample.

The development of viscous-crude oil and water separation technology is important for overcoming pollution caused by oil spills. Although some separators responding to light, electric, and temperature have been proposed, their poor structural homogeneity and inferior controllability, together with weak capillary forces, hinder the rapid salvage of viscous crude oil. Herein, a Joule-heated hydrophobic porous oil/water separator is reported, which has advantages of low energy consumption (169.

Accurate and rapid diagnosis of traumatic brain injury (TBI) is essential for high-quality medical services. Nonetheless, the current diagnostic platform still has challenges in rapidly and accurately analysing clinical samples. Here, we prepared a highly stable, repeatable and sensitive gold-plated silver core-shell nanowire (Ag@AuNWs) for surface-enhanced Raman spectroscopy (SERS) metabolic fingerprint diagnosis of TBI.

Wound care presents an imposed financial burden for healthcare organizations, prompting the need for novel and cost-efficient dressings. In this study, we address this challenge by introducing a novel approach to fabricate antibacterial alginate-based fibrous materials using a combination of wet spinning and the wet-laying method, which offer advantages including structural and functional properties such as breathability, nontoxicity, biocompatibility, and cost-effectiveness. The wet spinning method was employed to develop porous and non-porous Ca-alginate fibers with diameters of 100 ± 4.
