We report large-scale synthesis of silica nanowires (SiONWs) using an excimer laser ablation method. Silica was produced in the form amorphous at a diameter ∼15 nm and length up to hundreds micrometers. The SiONWs emit stable high brightness blue light energies 2.65 3.0 eV. intensity emission is two orders magnitude higher than that porous silicon. may have potential applications high-resolution optical heads scanning near-field microscope or nanointerconnections future integrated devices.
Li 2 S is one of the most promising cathode materials for Li‐ion batteries because its high theoretical capacity and compatibility with Li‐metal‐free anode materials. However, poor conductivity electrochemical reactivity lead to low initial severe decay.

Among these derivatives, methylene blue (MB) possesses reversibility extremely fast kinetics...
Abstract Given the high energy density, alkali metals are preferred in rechargeable batteries as anodes, however, with significant limitations such dendrite growth and volume expansion, leading to poor cycle life safety concerns. Herein a room‐temperature liquid alloy system is proposed possible solution for its self‐recovery property. Full extraction of metal ions from ternary brings it back binary eutectic, thus enables self‐healing process cracked or pulverized structure during cycling. A...
Stretchable energy-storage devices receive considerable attention due to their promising applications in future wearable technologies. However, they currently suffer from many problems, including low utility of active materials, limited multidirectional stretchability, and poor stability under stretched conditions. In addition, most proposed designs use one or more rigid components that fail meet the stretchability requirement for entire device. Here, an all-stretchable-component sodium-ion...
