Abstract 2D transition metal carbides and nitrides, known as MXenes, are an emerging class of materials with a wide spectrum potential applications, in particular electrochemical energy storage. The hydrophilicity MXenes combined their metallic conductivity surface redox reactions is the key for high‐rate pseudocapacitive storage MXene electrodes. However, symmetric supercapacitors have limited voltage window around 0.6 V due to possible oxidation at high anodic potentials. In this study,...
We developed stretchable and self-healable MXene hydrogel that can sense complex motions without multiple sensor arrays.
Selenide-based electrocatalysts and scaffolds on carbon cloth are successfully fabricated demonstrated for enhanced water oxidation applications. A max-imum current density of 97.5 mA cm(-2) at an overpotential a mere 300 mV small Tafel slope 77 dec(-1) achieved, suggesting the potential these materials to serve as advanced oxygen evolution reaction catalysts.
We demonstrate that poly(vinylidene fluoride) (PVDF)-based percolative composites using two-dimensional (2D) MXene nanosheets as fillers exhibit significantly enhanced dielectric permittivity. The fluoride-trifluoro-ethylene-chlorofluoroehylene) (P[VDF-TrFE-CFE]) polymer embedded with 2D Ti3C2Tx reaches a permittivity high 105 near the percolation limit of about 15.0 wt % loading, which surpasses all previously reported made carbon-based in same polymer. With up to 10 loss...
Abstract Wearable electrochemical biosensors for sweat analysis present a promising means noninvasive biomarker monitoring. However, sweat‐based sensing still poses several challenges, including easy degradation of enzymes and biomaterials with repeated testing, limited detection range sensitivity enzyme‐based caused by oxygen deficiency in sweat, poor shelf life sensors using all‐in‐one working electrodes patterned traditional techniques (e.g., electrodeposition screen printing). Herein,...
Abstract Water electrolysis is regarded as an efficient and green method to produce hydrogen gas, a clean energy carrier that holds the key solving global problems. So far, efficiency large‐scale application of water are restricted by electrocatalytic activity applied catalysts. Recently, reconstruction phenomenon electrocatalysts during catalytic reaction has been discovered, which could form reactive sites for both oxygen evolution reactions. Regulation process generate large number...
Abstract In this work, a simple lignin‐based laser lithography technique is developed and used to fabricate on‐chip microsupercapacitors (MSCs) using 3D graphene electrodes. Specifically, lignin films are transformed directly into laser‐scribed (LSG) electrodes by one‐step CO 2 irradiation. This step followed water lift‐off process remove unexposed lignin, resulting in with the designed electrode patterns. The LSG hierarchically porous, electrically conductive (conductivity up 66.2 S cm −1...
The acidic oxygen evolution reaction (OER) has long been the bottleneck of proton exchange membrane water electrolyzers given its harsh oxidative and corrosive environments. Herein, we suggest an effective strategy to greatly enhance both OER activity stability Co3O4 spinel by atomic Ru selective substitution on octahedral Co sites. resulting highly symmetrical Ru-O-Co collaborative coordination with strong electron coupling effect enables direct dioxygen radical pathway. Indeed, experiments...

Abstract Proton exchange membrane (PEM) water electrolysis holds great promise in revolutionizing clean energy production by enabling the efficient generation of hydrogen. Nevertheless, a formidable challenge persists realm designing electrocatalysts that are both highly active and acid‐resistant during oxygen evolution reaction (OER), thereby mitigating substantial kinetic barrier. In this study, facile synthesis iridium‐yttrium (IrY) alloy nanocatalysts via thermal shock method is...
Abstract Microsupercapacitors (MSCs) with high energy densities offer viable miniaturized alternatives to bulky electrolytic capacitors if the former can respond at kilo Hertz (kHz) or higher frequencies. Moreover, MSCs fabricated on a chip be integrated into thin‐film electronics in compatible manner, serving function of ripple filtering units harvesters from high‐frequency sources.

Ultrasound is a source of ambient energy that rarely exploited. In this work, tissue-mimicking MXene-hydrogel (M-gel) implantable generator has been designed to convert ultrasound power into electric energy. Unlike the present harvesting methods for harvesters, our M-gel based on an electroacoustic phenomenon known as streaming vibration potential. Moreover, output can be improved by coupling with triboelectrification. We demonstrate potential powering devices through quick charging gadgets,...
