Freestanding single-crystal complete nanorings of zinc oxide were formed via a spontaneous
self-coiling process during the growth of polar nanobelts. The nanoring appeared to be …

A low-cost high-performance solid-state flexible asymmetric supercapacitor (ASC) with α-MnO
2 nanowires and amorphous Fe 2 O 3 nanotubes grown on flexible carbon fabric is first …

Zinc oxide, an important semiconducting and piezoelectric material, has three key characteristics.
First, it is a semiconductor, with a direct bandgap of 3.37 eV and a large excitation …

A previously unknown rigid helical structure of zinc oxide consisting of a superlattice-structured
nanobelt was formed spontaneously in a vapor-solid growth process. Starting from a …

A series of flexible nanocomposite electrodes were fabricated by facile electro-deposition of
cobalt and nickel double hydroxide (DH) nanosheets on porous NiCo 2 O 4 nanowires …

Water-soluble K7[CoIIICoII(H2O)W11O39] (1) was tested as the first cobalt-containing
Keggin polyoxometalate catalyst for efficient O2 production via both visible-light driven and …

The shapes of noble metal nanocrystals (NCs) are usually defined by polyhedra that are
enclosed by {111} and {100} facets, such as cubes, tetrahedra, and octahedra. Platinum NCs of …

Surface-enhanced Raman scattering (SERS) is a powerful spectroscopy technique that can
provide non-destructive and ultra-sensitive characterization down to single molecular level, …

Grasslands are under severe threat from ongoing degradation, undermining their capacity to
support biodiversity, ecosystem services and human well-being. Yet, grasslands are largely …

Despite the remarkable progress in power conversion efficiency of perovskite solar cells,
going from individual small-size devices into large-area modules while preserving their …
