α-MoO3 belt crystals consisting of nanosheets stacked along their [010]-axes have been synthesized (without intentional use of a substrate) and further exfoliated to form 2D nanosheets. Raman mode softening of Ag (~818 cm−1) was observed from the thinner layers and theoretically validated for the first time. Aqueous exfoliation induces a blue shift in the α-MoO3 nanosheet absorption edge.

Fibrillation of the amyloid peptide Aβ 1-40 induced by Cu(II) is prevented by the non-toxic glycodendrimer G4S. A multidisciplinary dynamic light scattering (DLS), circular dichroism (CD), fluorescence, electron paramagnetic resonance (EPR), and molecular modeling study elucidating the interactions into binary and ternary systems constituted by Aβ 1-40, Cu(II), and glycodendrimer G4S.

A simple one-step electrospinning technique is developed to modulate the electrical properties, especially the threshold voltage, of In2O3 nanofiber field-effect transistors by doping with different Mg concentrations. By integrating with a high-κ dielectric layer, the device performance of the nanfiber transistors can be further improved, indicating the technological potency of this simple doping scheme for high-performance, low-operating-power, and large-scale nanoelectronics.

Hollow carbon nanofibers (HCFs) that combine the features of adjustable pore sizes, closed ends, and thin carbon shells are prepared for the first time as hosts for Li-S battery cathodes. The unique structures lead to high rate capacities (e.g., 860 mA·h·g−1 at 4.0 C (1 C = 1.675 A·g−1)) and stable cyclability over 500 cycles for S@HCF.

A multimodal contrast agent achieves diffusion reflection and fluorescence lifetime imaging microscopy multimodal imaging of macrophages in vitro. The new contrast agent based on gold nanorods@silica@carbon dots core-shell. This system will potentially enhance detection sensitivity compared to the current far-field imaging technique, and will also establish a new method to quantitatively and noninvasively detect targeted nanoparticles in vivo, affording a promising theranostics tool.

Self-standing lotus root-like porous carbon nanofibers (PCNFs) are developed and utilized as supporting materials for anchoring electroactive CoP nanoparticles. These unique PCNFs have longitudinal channels and mesopores on the outer and inner carbon walls, which enhances the contact between the electrolyte and catalyst. This endows the CoP/PCNF composites with excellent hydrogen evolution reaction (HER) performance at an all-pH range.

Graphene oxide-decorated Fe2(MoO4)3 microflower composite was fabricated via a facile one-step water-bath method, in which the Fe2(MoO4)3 was constructed by numerous nanosheets. The composite demonstrates a high specific capacity, excellent rate capability, and stable cycling performance when used as the anode for lithium and sodium storage.
