Abstract Atherosclerosis, a chronic disease associated with metabolism, poses significant risk to human well‐being. Currently, existing treatments for atherosclerosis lack sufficient efficiency, while the utilization of surface‐modified nanoparticles holds potential deliver highly effective therapeutic outcomes. These can target and bind specific receptors that are abnormally over‐expressed in atherosclerotic conditions. This paper reviews recent research (2018–present) advances various...

Self-propelling chemical motors have thus far required the fabrication of Janus particles with an asymmetric catalyst distribution. Here, we demonstrate that simple, isotropic colloids can spontaneously assemble to yield dimer self-propel. In a mixture titanium dioxide photo-chemical catalytic activity and passive silica colloids, light illumination causes diffusiophoretic attractions between active leads formation dimers. The dimers constitute symmetry-broken motor, whose dynamics be fully...

When asymmetric Janus micromotors are immobilized on a surface, they act as chemically powered micropumps, turning chemical energy from the fluid into bulk flow. However, such pumps have previously produced only localized recirculating flows, which cannot be used to pump in one direction. Here, we demonstrate that an array of three-dimensional, photochemically active Au/TiO2 pillars can water. Upon UV illumination, water-splitting reaction rapidly creates directional flow above surface. By...

This study aimed to examine how communication modes affect creative idea generation in groups. Three mode conditions were created: natural (N), turn-taking (T), and electronic brainstorming (E). Participants randomly recruited grouped dyads solve one alternative uses task (AUT) each condition, during which functional near-infrared spectroscopy (fNIRS)-based hyperscanning was used record interpersonal neural responses. No difference observed AUT fluency across the three conditions, but...
