Fenestrated Microneedle Biosensor for Continuous In Vivo Lactate Monitoring in Interstitial Fluid

ABSTRACT Lactate is a key biomarker of tissue metabolism and oxygenation, yet clinical assessment still relies on intermittent blood tests that overlook rapid metabolic dynamics and disrupt clinical workflows. Continuous transdermal monitoring of lactate in interstitial fluid (IS...

Selective Electrochemical Lithium-Ion Extraction from Low-Grade Lithium Sources with Optimized Pulsed Operation

Abstract Lithium recovery from brines, particularly low-grade resources, remains a major challenge. Here, we develop an electrochemical lithium-ion extraction system based on carbon-coated LiFePO4 as the working electrode and systematically elucidate how the carbon coating govern...

A hydration-dependent minimum in finger pad friction on rough surfaces

Abstract Finger pad friction is central to object manipulation and tactile perception, and surface roughness is a key parameter for its control. In a systematic investigation of finger pad friction on aluminum surfaces with varying roughness, measurements from 61 participants rev...

Hydration Asymmetry and Solvent-Mediated Charge Balancing in Microporous Carbons: An NMR Study of Aqueous and Organic Electrosorption

Abstract Aqueous electrolytes are attracting increasing interest in supercapacitor applications due to their high sustainability and ionic conductivity relative to conventional organic systems. However, the distinct solvation properties of water and their impact on (electro)sorpt...

Variation in glabrous skin physiology across anatomical locations on the human hand

Abstract Skin physiology varies greatly between anatomical locations, with impact on tactile sensitivity. Research on the variations in morphology and physiology between different anatomical locations of glabrous skin is limited so far. This study investigates the morphology and...
