3D printing technology has demonstrated great potential in fabricating flexible and customizable high‐performance batteries, which are highly desired in the forthcoming intelligent and ubiquitous energy era. However, a significant performance gap, especially in cycling stability, still exists between the 3D‐printed and conventional electrodes, seriously limiting the practical applications of 3D‐printed...
The rate‐determining step of the oxygen evolution reaction based on a semiconductor photoanode is the formation of the OO bond. Herein, polyethylene glycol (PEG)‐modified BiVO4 photoanodes are reported, in which protons can be transferred quickly due to the high proton conductivity of PEG, resulting in the acceleration of the OO bond formation rate. These are fully demonstrated by different kinetic...
Photoelectrochemical Water Splitting
In article number 2201410, Yi Zhu, Yongge Wei, and co‐workers show that due to the high proton conductivity of polyethylene glycol (PEG), protons can be transferred quickly out of H2O on the surface of PEG modified BiVO4 photoanodes to accelerate the formation of O2 gas during the splitting of water.
2D van der Waals (vdW) semiconductors hold great potentials for more‐than‐Moore field‐effect transistors (FETs), and the efficient utilization of their theoretical performance requires compatible high‐k dielectrics to guarantee the high gate coupling efficiency. The deposition of traditional high‐k dielectric oxide films on 2D materials usually generates interface concerns, thereby causing the carrier...
This study reports a double‐targeting “nanofirework” for tumor‐ignited imaging to guide effective tumor‐depth photothermal therapy (PTT). Typically, ≈30 nm upconversion nanoparticles (UCNP) are enveloped with a hybrid corona composed of ≈4 nm CuS tethered hyaluronic acid (CuS‐HA). The HA corona provides active tumor‐targeted functionality together with excellent stability and improved biocompatibility...
