Summary: Oxide semiconductors with multi-shell hollow architecture have great potential as sensing materials in high-performance gas sensors. In this study, solid, core-shell, and double-shell zinc oxide (ZnO) microspheres were successfully synthesized using a template-free method. Compared to the other two structures, the gas sensor based on the double-shell structure exhibited the highest response to 100 ppm ethanol at 275 degrees C (-47.4), which was 4.8 times higher than that of the solid structure (-9.8) under the same conditions. Furthermore, the detection limit of the double-shell ZnO microsphere was as low as 1 ppm. The enhancement mechanism of the ethanol gas-sensing performance was systematically discussed.

Summary: We present a facile method for the synthesis of Ag-ZnO nanohybrids consisting of Ag nanoparticles decorated ZnO nanobullets through bioreduction. The nanohybrids exhibit strong antibacterial action against several bacteria, and the antibacterial mechanism is attributed to the ROS-induced oxidative stress. The results from different assays confirm enhanced lipid peroxidation, significant protein leakage, and cell wall damage in bacteria treated with Ag-ZnO nanohybrids.

Summary: This method involves the large-scale fabrication of bowl-shaped colloidal particles using an emulsion templating technique, where compliant seed particles are deformed by surface tension on oil droplets as templating surfaces. By adjusting droplet size and seed particle diameter, the final particle shape can be precisely controlled, ranging from shallow lenses to deep bowls. The resulting uniformly-shaped colloidal particles allow for depletion-mediated assembly of flexible colloidal chains and clusters.
