We report that the oxygen evolution reaction activity of nickel foam can be enhanced remarkably via only simple immersion in a ferric nitrate solution at room temperature. We demonstrate that the oxidation of the nickel foam surface by nitrate ions can increase the near-surface concentrations of OH and Ni2+ ions, which results in the in situ deposition of a highly active amorphous Ni-Fe hydroxide layer.

Novel Na-rich sodium iron hexacyanoferrate nanospheres with a hierarchical hollow architecture have been fabricated by a facile template method. Due to the unique hollow sphere morphology, sodium iron hexacyanoferrate nanospheres can achieve superior electrochemical performance as the cathode material for sodium-ion batteries.

Unlike the extinction coefficient per nanocrystal (εNC), the extinction coefficient per CdE unit (εunit) is found to be insensitive to the shape and ligand coverage of the nanocrystals and can be determined accurately.

We report the in vivo detection of nucleic acid targets using a promising type of surface-enhanced Raman scattering (SERS) nanosensor implanted in the skin of a large animal model (pig). The in vivo nanosensor used in this study involves an"inverse molecular sentinel"(iMS) detection scheme using plasmonics-active nanostars as an efficient in vivo sensing platform.

Reverse filament growth has proved to be key for obtaining a first-in-class Cu-based switching device with an endurance of up to 106 cycles with a 102 read window, low power (sub-10-µA) switching operation, outstanding disturb immunity, and optimal stability of the filament over time.

Self-standing anode materials of ultrasmall γ-Fe2O3 nanodots (~3. 4 nm) homogeneously encapsulated in interlinked porous N-doped carbon nanofibers were prepared by an electrospinning technique, and exhibited unprecedentedly high cyclic stability in both half and full Na-ion batteries.

A simple, scalable, and commercially applicable process for the fabrication of high-performance photocatalysts is developed. Nanocomposites composed of SnO2 colloids and edge-oxidized graphene-oxide sheets reduce CO2 to CH4 more efficiently than SnO2 or commercialized TiO2.
