Biomimic albumin-bound paclitaxel dimeric prodrug nanoparticles were prepared by co-precipitating HSA with a paclitaxel dimer bridged with thioether linker and photosensitizer IR780 iodide. The described technology unifies the biomimetic trait of HSA, high drug loading, triggered drug release, and synergistic photothermal and chemotherapy into one formulation.

Regulation of nanoparticle (NP) cellular uptake is achieved via the helical conformation and orientation of the anchoring polypeptides. Our results found that the helical polypeptide anchoring its C-terminus to the surface of the NPs gave rise to significantly higher cellular internalization than all other control groups.

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

Nanocrystalline carbon-coated Na3V2(PO4)2F3 by polyol process registered excellent stable cyclability about 88% of the initial capacity at 15 C (1,930.5 mA·g-1) after a prolonged cycle life span of 1,500 cycles.

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 22.4μg·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 Moiré patterns and selected-area electron diffraction patterns.
