Lithiation-delithiation cycles of individual aluminum nanowires (NWs) with naturally oxidized Al(2)O(3) surface layers (thickness 4-5 nm) were conducted in situ a transmission electron microscope. Surprisingly, the lithiation was always initiated from layer, forming stable Li-Al-O glass tube thickness about 6-10 nm wrapping around NW core. After inner Al core took place, which converted single crystal to polycrystalline LiAl alloy, volume expansion 100%. The survived 100% expansion, by...
The intrinsic scaling-down ability, simple metal-insulator-metal (MIM) sandwich structure, excellent performances, and complementary metal-oxide-semiconductor (CMOS) technology-compatible fabrication processes make resistive random access memory (RRAM) one of the most promising candidates for next-generation memory. RRAM device also exhibits rich electrical, thermal, magnetic, optical effects, in close correlation with abundant switching (RS) materials, metal-oxide interface, multiple RS...
Abstract Intracellular viscosity is a crucial parameter that indicates the functioning of cells. In this work, we demonstrate utility TPE‐Cy, cell‐permeable dye with aggregation‐induced emission (AIE) property, in mapping inside live Owing to AIE characteristics, both fluorescence intensity and lifetime are increased along an increase viscosity. Fluorescence imaging cells stained TPE‐Cy reveals lipid droplets much shorter than from general cytoplasmic region. The loose packing lipids droplet...
Abstract The mimicking of both homosynaptic and heterosynaptic plasticity using a high‐performance synaptic device is important for developing human‐brain–like neuromorphic computing systems to overcome the ever‐increasing challenges caused by conventional von Neumann architecture. However, commonly used devices (e.g., memristors transistors) require an extra modulate terminal mimic plasticity, their capability simulation limited low weight adjustability. In this study, WSe 2 ‐based...

To understand the fundamental aspects of SnO2 catalytic materials and develop applicable catalysts for VOCs combustion, samples possessing stable varied surface areas are controllably constructed applied to toluene deep oxidation. By improving area, Sn4+ cation exposure is improved, thus increasing its acidity, which benefits molecule adsorption activation. Furthermore, more defects can be generated, hence inducing generation abundant active oxygen sites, favorable further oxidizing adsorbed...
Ultrathin gold (Au) films are a critical component in plasmonics, metal optics, and nano-electronics devices. However, fabricating ultrathin Au faces great challenge due to the dewetting behavior of when being deposited onto an oxide (such as SiO2/Si or Al2O3) substrate. This problem is often relieved by introducing organic adhesion layer bind film with While interdiffusion thermal instability layers negatively affect physical properties films. Besides, this kind usually untransferable...
