Hollow Co<sub>2</sub>P nanoflowers composed of nanorods have been prepared <italic>via</italic> a one-step method; they exhibit an ultralong cycle life in supercapacitor applications.
Abstract Aerogels have demonstrated tremendous potentials for various applications, including thermal insulation, environmental protection, and separation. However, aerogels as porous frameworks to host functional liquids (such phase change fluids, PCFs) is a more promising application, attributing their large specific surface area, high porosity, strong capillary force. Herein, the original aramid nanofiber (OANF, i.e., Kevlar) aerogel film densified ANF (DANF) are fabricated thereafter...
Tribocatalysis, as a new approach in environmental purification, has drawn increasing attention the past few years. In this work, we successfully convert mechanical energy to chemical by Bi12TiO20, which was synthesized hydrothermal method. Under magnetic stirring, electrons transfer from surface of Bi12TiO20 polytetrafluoroethylene-sealed bar due their friction. Moreover, holes that remain on provide oxidation properties process for organic matter degradation. According series tests, it is...
By carefully controlling the reacting conditions, including atmosphere, temperature, and time, we directly acquire nanowires of γ-Fe2O3 from α-Fe2O3 in a reduced atmosphere. X-ray diffraction, photoelectron spectroscopy, Raman spectrum, transmission electronic microscope analyses demonstrate that are single-crystalline γ-Fe2O3. The have diameter ranging 50 to 90 nm their typical lengths range 10∼20 μm. optical property is observed by photoluminescence spectrum. magnetic behavior it...
By carefully controlling the reacting time, temperature, and humidity, we have prepared Co3O4 nanowires by heating a pure cobalt foil in atmosphere. Scanning electronic microscopy demonstrates that diameter ranging from 20 to 100 nm their typical lengths are range of 10−20 μm. X-ray diffraction, photoelectron spectroscopy, Raman spectrum, transmission analyses demonstrate Co3O4. The optical property is determined photoluminescence spectrum. magnetic behavior it investigated measurement...

Carbon nanomaterials, as novel functional and structural materials with unique properties, hold significant potential in information technology nanodevices. However, the self-catalytic growth mechanism of graphite shells derived from carbon sources, facilitated by diverse catalysts, necessitates further exhaustive investigation. To tackle this challenge, we conducted a study utilizing environmental transmission electron microscopy (ETEM) at atomic resolution to investigate pyrolysis metal...
The advent of two-dimensional (2D) ferroelectrics offers a new paradigm for device miniaturization and multifunctionality. Recently, 2D α-In2Se3 related III–VI compound manifest room-temperature ferroelectricity exhibit reversible spontaneous polarization even at the monolayer limit.
