Flexible and stretchable triboelectric nanogenerators (TENGs) have been rapidly advanced owing to the demand for portable wearable electronic devices that can work under universal or motional circumstances. While versatile materials be applied in a TENG as dielectric materials, flexible cost-effective electrodes are crucially important output performance of TENGs. Herein, we developed poly(vinyl alcohol) (PVA) hydrogel doped with novel two-dimensional material, graphitic carbon nitride...
Abstract The commercial utilization of Zn metal anodes with high plating capacity is significantly hindered by the uncontrolled growth dendrites and associated side reactions. Herein, a robust artificial ion‐sieving MXene flake (MXF)‐coating layer, abundant polar terminated groups, constructed to regulate interfacial 2+ deposition behavior. In particular, fragmented MXF coupled in situ generated quantum dots not only has strong affinity homogenize electric fields but also generates numerous...
Triboelectric nanogenerators (TENGs) have attracted many researchers' attention with their remarkable potential despite the fact that practical implementation requires further improvement in electric performance. In this work, a novel graphene phase two-dimension material, graphitic carbon nitride (g-C3N4), was employed for development of TENG material enhanced features. An electrospun nanofibrous PA66 membrane doped g-C3N4 fabricated as multifunctional harvesting different kinds mechanical...
Abstract With burgeoning considerations over energy issues and carbon emissions, harvesting devices such as triboelectric nanogenerators (TENGs) are developed to provide renewable sustainable power. Enhancing electric output other properties of TENGs during operation is the focus research. Herein, two species (Nb 2 S C Ta C) a new family 2D materials, Transition Metal Carbo‐Chalcogenides (TMCCs), first employed develop with doping into Polydimethylsiloxane (PDMS). Compared control samples,...
The energy harvesting crisis has caused great necessity for new technologies, among which triboelectric nanogenerators (TENGs) garnered global attention. Based on our previous research a novel 2D material graphitic carbon nitride (g-C3N4), this work explores the influence of g-C3N4 hybrid dopants with Polydimethylsiloxane (PDMS) performance enhancement TENGs. More specifically, systematic experiments different ratios were conducted, including Ag nanowires g-C3N4, nanotubes and MXene g-C3N4....
Abstract Aqueous zinc‐ion batteries (AZIBs) have attracted more and attention owing to their high safety, low cost, environmental friendliness. Mn‐based materials are considered as one of the most promising cathode for AZIBs because output voltage, eco‐friendliness, abundance. However, electrochemical activity manganese dissolution Mn 3 O 4 lead specific capacity inferior cycling stability, hindering its practical applications. Herein, a facile low‐cost strategy is designed that combines...
The invention of triboelectric nanogenerators (TENGs) provides an effective approach to the sustainable power energy. Liquid-solid interface-based TENGs have been researched in virtue less friction for harvesting energy from raindrops, rivers, and oceans form water flows. However, based on droplet tubes rarely investigated. In this study, we proposed a new tube-based TENG (DT-TENG) with free-standing reformative grating electrodes. Both straight curved DT-TENGs designed fabricated including...
