This review describes state-of-the-art scientific and technological developments of electrospun nanofibers their use in self-cleaning membranes, responsive smart materials, other related applications. Superhydrophobic self-cleaning, also called the lotus effect, utilizes right combinations surface chemistry topology to form a very high contact angle on drive water droplets away from it. The high-contact-angle easily roll off surface, carrying with them dirt, particles, contaminants by way...

Abstract Reversible intercalation of potassium‐ion (K + ) into graphite makes it a promising anode material for rechargeable batteries (PIBs). However, the current anodes in PIBs often suffer from poor cyclic stability with low coulombic efficiency. A stable solid electrolyte interphase (SEI) is necessary stabilizing large interlayer expansion during K insertion. Herein, localized high‐concentration (LHCE) designed by adding highly fluorinated ether concentrated potassium...

Common homogeneous electrochemical (HEC) sensors usually suffer from the drawbacks of high background signal, low signal-to-noise ratio, and even false positive results due to preaddition electroactive substances. Thus, it is necessary develop novel HEC based on in situ generation substances overcome these shortcomings, which, however, underexplored. In this work, two-dimensional (2D) nanozymes, i.e., cobalt-doped 2D Ti3C2 MXene nanosheets (CMNSs), with excellent peroxidase-like properties...
