Multiplexed ultrasound and photoacoustic imaging is achieved through the use of color-coded perfluorocarbon nanodroplets. Specifically, distinct subpopulations of laser-activated perfluorocarbon nanodroplets produce optical wavelength-selective ultrasound and photoacoustic signals. The dynamic ultrasound and photoacoustic contrast produced by these agents allows the simultaneous acquisition and discrimination of quantitative spatial information from distinct biological targets, which were tested and demonstrated in vivo.

The insertion of lithium enlarges the V每O bond in V2O5, which further weakens the V每O skeleton. Also, it shortens the V每V bond, which makes the V每O polyhedra more quenched.

Hexagonal boron nitride nanosheet (h-BNNS) acts as a metal-free electrocatalyst for high-performance artifical N2 fixation to NH3, which attains a high NH3 formation rate of 22.4米g﹞h−1﹞mg−1cat. and a high Faradic efficiency of 4.7% at -0.75 V vs. RHE in 0.1 M HCl. Density functional theory calculations reveal that the unsaturated boron at the edge site of h-BNNS can activate inert N2 molecule and dramatically reduce the energy barrier for NH3 formation.

Transition metal dichalcogenides (TMDs) represent a large family of layered two-dimensional materials. This work reveals that NbS2 and TaTe2 are the most effective oxygen reduction reaction (ORR) catalysts with over-potential of 0.54 V among the studied TMDs and the ORR activity of NbSe2 can be tuned effectively by the strain.

A new ratiometric nanoprobe (UCNP-TB) possessing synchronous detectability of redox couple glutathione/hydrogen peroxide (GSH/H2O2) was developed based on a multi-spectral upconverting nanophosphor as the luminescence resonance energy transfer (LRET) donor and two dye molecules as the acceptors. We can utilize it to elucidate the redox status within the drug-resistant tumor and the drug-induced hepatotoxic liver via the ratiometric upconversion luminescence (UCL) imaging.

Ultra-high precision structural mapping in the transmission electron microscope is used to study the nanometre strain distribution in an indium phosphide nanowire containing a screw dislocation. The Eshelby twist rate is shown to be an inaccurate method to determine the dislocation displacement, however radial strain analysis confirms the correct dislocation structure.

In situ TEM observation shows that the migration channels of Au atoms on MoS2 and the coalescence of adjacent nanoparticles may lead to the formation of Au dendrites, in which the epitaxial alignment between Au and MoS2 lattices is verified by the periodic Moir谷 patterns and selected-area electron diffraction patterns.
