A multi-level spatial confinement strategy is proposed for the fabrication of ultra-dispersed 1T-Co-MoS 2 nanoclusters, which exhibit remarkable electrocatalytic activity and durability HER.

Control of fluid dynamics at the micrometer scale is essential to emulsion science and materials design, which is ubiquitous in everyday life and is frequently encountered in industrial applications. Most studies on multiphase flow focus on oil-water systems with substantial interfacial tension. Advances in microfluidics have enabled the study of multiphase flow with more complex dynamics. Here...

A rotating suspension of nonbuoyant particles can develop striking inhomogeneities in particle concentration, with regular bands of high and low concentration along the symmetry axis. We report Stokes-flow simulations showing that the formation of axial bands is correlated with an inhomogeneous particle distribution in the radial plane. An order parameter, based on the average angular velocity ...

This research is focused on the adsorption modification of detonation nanodiamond surfaces with antibiotics for their further use as smart materials cardiovascular surgery purposes, namely bioprostheses modifiers. Tritium-labeled amikacin and levofloxacin were used tracers process control. We found that nanodiamonds form complexes via physical adsorption, while in case amikacin, electrostatic a...

Low-temperature thermoluminescence has been used in attempt to understand the particular structure of ultra high dilutions. Samples are activated by irradiation after freezing at the temperature of liquid nitrogen (77 degrees K). Experimental results show that, in the course of rewarming, the thermoluminescent glow is susbtantially different between dilutions of different substances. It is sugg...

Electron spins of diamond nitrogen-vacancy (NV) centres are important quantum resources for nanoscale sensing and quantum information. Combining NV spins with levitated optomechanical resonators will provide a hybrid quantum system for novel applications. Here we optically levitate a nanodiamond and demonstrate electron spin control of its built-in NV centres in low vacuum. We observe that the ...
