Current clothing trends: A wearable and flexible fiber supercapacitor with a fully encapsulated electrolyte is formed by wrapping plastic wire covered ZnO nanowires (NWs; see SEM image) around Kevlar gold-coated NWs. This shows promise as highly efficient, energy storage device. Detailed facts of importance to specialist readers are published "Supporting Information". Such documents peer-reviewed, but not copy-edited or typeset. They made available submitted the authors. Please note: The...
The first integration of multiple energy harvesters and a storage device along single fiber using ZnO nanowires (NWs) graphenes as the basic materials is reported. This generation allows simultaneous harvesting solar mechanical energy. unique architecture fiber-based electrodes use NWs, active material could be useful for future development flexible wearable electronics.
Recent years have witnessed the explosive development of highly sensitive smart sensors based on conductive polymer foam materials. However, design and multifunctional polymeric composites as applied in complex solvent oil environments remain a critical challenge. Herein, we synthesize vinyl-terminated polytrifluoropropylmethylsiloxane through anionic ring-opening polymerization to fabricate fluorosilicone rubber (FSiRF) materials with nanoscale wrinkled surfaces reactive Si-H groups via...
We demonstrate a fully stand-alone, self-powered environmental sensor driven by nanogenerators with harvesting vibration energy. Such system is made of ZnO nanowire-based nanogenerator, rectification circuit, capacitor for charge storage, signal transmission LED light and carbon nanotube-based Hg2+ ion sensor. The circuit lights up the indicator when it detects mercury ions in water solution. It first demonstration nanomaterial-based, detecting toxic pollutant.
Abstract Owing to their high sensitivity across a wide stress range, mechanical reliability, and rapid response time, flexible polymer foam piezoresistive sensors have been extensively used in various fields. The reliable application of these under harsh environments, however, is severely limited by structural devastation poor interfacial bonding between polymers conductive nanoparticles. To address the above issues, robust MXene/CNT nanocoatings on surface, where chemical assembly MXene...
Novel ITO-Si nanowire (NW) metal-insulator-semiconductor (MIS) photodetectors were fabricated by using n-type Si NWs as detection units and ITO films top gate electrodes. Measurements on the NW based device reveal a significant photoresponse, including photocurrent generation with an external quantum efficiency (EQE) of approximately 35% at peak wavelength 600 nm zero bias, EQE 70% 800 - 0.5 V bias. The shows flat low reflectance almost constant up to 60 degrees incident angle illumination,...
In this work, the morphology of ZnO nanostructures is engineered to demonstrate enhanced supercapacitor characteristics nanocones (NCs) compared nanowires (NWs). NCs are obtained by chemically etching NWs. Electrochemical and NWs extensively investigated dependent capacitive performance one dimensional nanostructures.

Abstract Selenium‐based electrodes have garnered attention for their high electrical conductivity, compatibility with carbonate electrolytes, and volumetric capacity comparable to sulfur electrodes. However, real‐time application is hindered by rapid deterioration from the “shuttle effect” of polyselenides volume fluctuations. To address these challenges, a hybrid Se@ZIF‐67/Mo‐MXene‐derived (Se@Co‐NC/Mo 2 C) nanoarchitecture developed via an economically viable in situ electrostatic...
Texture-controlled growth of ZnO films on substrates general materials at room temperature by pulsed laser deposition was demonstrated. The texture the film changed progressively from (001) to (110) (100) as fluence increased 2 J cm(-2) up 45 cm(-2). Application textured Si wafers seed layers for growing aligned nanowire arrays (grown along c-axis) with controlled orientation relative substrate surface individual forms an epitaxial relationship grain that nucleated it; therefore long axis...
