Plasmonic Ag@Zn core@shell nanoparticles are formed in a unique way inside a pristine environment employing the helium droplet synthesis approach. After subsequent oxidation the Ag@ZnO nanoparticles are investigated by several analysis techniques including scanning transmission electron microscopy, ultraviolet photoelectron spectroscopy, and two-photon photoelectron spectroscopy

The highly porous Si/SiOx anode with cross-linked mesopores is synthesized through insufficient magnesiothermic reduction from highly porous silica spheres. The retained SiOx component protects the Si crystallite and porous structure from deforming, bringing about impressive electrochemical performance.

Tunable growth of all-inorganic perovskite nanorings with dual compositional phases of CsPbBr3 and CsPb2Br5 was reported, which was driven by the axial stress resulted from the lattice mismatch during the transformation of CsPbBr3 to CsPb2Br5.

Highly-efficient green emissive CDs (m-CDs) with the absolute quantum yield of 71.7% in water are prepared through a facile solvothermal method. Owing to the unique optical behavior, the m-CDs were used as a fluorescent probe for water quality identification, glucose detection, and two environment-friendly starch-based solidstate fluorescence materials (powder and film).

A surface-ligand protected reduction strategy was designed for the synthesis of one-dimensional (1D) MoO3−x nanobelts with tunable plasmonic absorption in a wide wavelength range from 200 to 2,500 nm. Owing to the broad plasmonic absorption and unique 1D nanostructure, the MoO3−x nanobelts were easily deposited as photothermal film in the interfacial solar evaporator, exhibiting excellent performance in solar steam generation.

The interface between oxide/oxide layers shows an inhomogeneous charge transport behavior, which reveals a high conductivity owing to interface-doped. A buffer layer not only reduces the interface trap density, but also effectively enhances the gate electric field modulation at the hetero-interface. Our device demonstrates a pronounced ultrahigh on/off ratio of ≥ 108, which is 8-order of magnitude higher than that of a device without buffer layer.

Flower-like NiCo2S4 with an excellent electrochemical performance is utilized as the anode for sodium-ion batteries under the ether electrolyte system at a voltage range of 0.3–3 V, and its sodium storage mechanism is studied by ex situ X-ray diffraction (XRD), Raman, X-ray photoelectron spectroscopy (XPS) and transmission electron microscopy (TEM). Moreover, quantitative kinetic analysis for NiCo2S4 also unravels the high contribution of pseudocapacitance mechanism in this system.
