One-dimensional (1D) vanadium-based nanostructures have advantageous properties and are showing emerging critical applications in the fields of catalysis, smart devices, and electrochemical energy storage. We herein timely gave an overview of the 1D vanadium pentoxide (VO)-based nanomaterials for these promising applications, especially regarding the merits of different synthetic methods, structures and properties combined with recent research frontiers in advanced energy storage, including batteries, supercapacitors and like. The high capacity, high rate and flexibility of 1D VO-based nanomaterials endow them with great potential in high-energy-density, high-power energy devices and specific/harsh environments.

Gradient porous carbon has become a potential electrode material for energy storage devices, including the aqueous zinc-ion hybrid capacitor (ZIHC). Compared with the sufficient studies on the fabrication of ZIHCs with high electrochemical performance, there is still lack of in-depth understanding of the underlying mechanisms of gradient porous structure for energy storage, especially the synergistic effect of ultramicropores (<1 nm) and micropores (1-2 nm). Here, we report a design principle for the gradient porous carbon structure used for ZIHC based on the data-mining machine learning (ML) method.

The extensive application of graphene nanosheets (GNSs) has raised concerns over risks to sensitive species in the aquatic environment. The humic acid (HA) corona is traditionally considered to reduce GNSs toxicity. Here, we evaluate the effect of sorbed HA (GNSs-HA) on the toxicity of GNSs to Gram positive Bacillus tropicus.

Monitoring subcellular organelle dynamics in real time and precisely assessing membrane heterogeneity in living cells are very important for studying fundamental biological mechanisms and gaining a comprehensive understanding of cellular processes. However, there remains a shortage of effective tools for these purposes. Herein, we propose a strategy to develop the exchangeable water-sensing probeAPBD for time-lapse imaging of dynamics in cellular membrane-bound organelle morphology with structured illumination microscopy at the nanoscale.
