At present, Ag nanoparticles have been widely used as Raman substrates, but their easy oxidation and aggregation have limited practical applications. In order to address the above problems, firstly, tetraethyl orthosilicate as a precursor was applied to synthesis silver coated with silica dioxide nanoparticles (Ag@SiO2). As a result, the surface of Ag nanoparticles is uniformly coated with a thin...
To enhance the robustness and lifespan of triboelectric nanogenerator (TENG) and facilitate its industrial applications, herein, a self‐switching mode TENG that combines the advantages of contact mode and noncontact mode TENG is presented. Noncontact mode TENG prevents material wear but generates insufficient power, whereas contact enhances power generation by increasing the charge density on the...
