A stick-type compact solid–water interacting triboelectric nanogenerator, called a SWING stick, is fabricated by utilizing anodized aluminum oxide (AAO) nanostructures on a curved aluminum tube. When applied in a compact design, the fundamental mechanism of solid-water contact electrification could be easily explored with highly controllable system.

A few-layered MoS2–C composite with high capacity and good cycling performance is successfully applied as a protective matrix for Si nanopowder. The MoS2–C composite material accommodates the large volume expansion of the Si nanopowder, but also prevents the formation and propagation of a SEI layer on the Si surface during repeated electrovoltaic cycling. MoS2–C composite microspheres embedded with 30 wt.% Si nanopowder with enhanced Li+ storage properties are evaluated as a novel anode material with superior electrochemical properties for lithium-ion batteries.

Dendritic mesoporous silica encapsulated magnetic nanospheres with radially oriented, large open as well as controllable pore size (5.7–10.3 nm) and shell thickness (40–100 nm) were fabricated through an effective oil-water biphase stratification coating strategy. The silica shell was suitably converted into dendritic mesoporous aluminosilicate core-shell nanospheres with unchanged porosity and notable strong acidic sites, exhibiting promising application in phosphate removal from wastewater.

A general strategy was established for the growth of rare-earth- vanadate shells on Au nanorod cores to form Au/GdVO4:Eu core/ shell heterostructures with an efficient integration of the plasmonic properties of the Au nanorods and the fluorescence properties of the rare-earth ions.

We plot the fitted light-emission intensities of the A, A–, and I peaks of CVD-grown monolayer WS2 as a function of the uniaxial tensile strain. Following its appearance, the I peak tends to increase in intensity as the strain increases, in contrast to the A and A– peaks. This is attributed to the strain-induced direct-to-indirect bandgap transition and agrees well with the calculated critical strain of ~2.6% that can lead to the transformation.
