Microplastics, which comprise one of the omnipresent threats to human health, are diverse in shape and composition. Their negative impacts on ecosystem health provide ample incentive design execute strategies trap degrade diversely structured microplastics, especially from water. This work demonstrates fabrication single-component TiO2 superstructured microrobots photo-trap photo-fragment microplastics. In a single reaction, rod-like with multiple trapping sites, fabricated exploit asymmetry microrobotic system advantageous for propulsion. The synergistically photo-catalytically fragment microplastics water coordinated fashion. Hence, model "unity diversity" is demonstrated here phototrapping photofragmentation During light irradiation subsequent photocatalysis, surface morphology transformed into porous flower-like networks that degradation. reconfigurable technology represents significant step forward efforts

Millirobot Based on a Phase-Transformable Magnetorheological Liquid Metal

ACS Applied Materials & Interfaces, Год журнала: 2023, Номер 15(31), С. 37658 - 37667

Опубликована: Июль 28, 2023

Droplet robots have attracted much attention in recent years due to their large-scale deformability and flexible mobility confined spaces. However, droplet are always difficult maintain rigid shapes, making them manipulate objects with large inertia. Moreover, low conductivity makes unable complete tasks such as circuit repair. Herein, a millirobot made from magnetorheological liquid metal is proposed address the problems. Specifically, (MLM) robot by engulfing iron particles into gallium–indium alloy, mass fraction of MLM determined microscopic observation rheological test. The possesses both solid properties, enabling plasticity, deformability, good conductivity, motion flexibility, object manipulation. can achieve almost all functions existing robots, including splitting, merging, navigating narrow channels, pushing objects. In addition, it also accomplish some other that for pulling objects, repairing damaged circuits selectively reversibly, suspended through plasticity. demos show traverse spaces repair damage reversibly. It believed enrich diverse functionalities future.
