Chemotactic Micro- and Nanodevices

Preparation of autonomous chemotactic micro- and nanomachines represents one of the most difficult challenges of modern materials science. To construct a device mimicking the behavior of many microorganisms, which evolved their chemotactic abilities during the millennia of evolution, places extreme demands on the imagination and abilities of researchers. However, with the chemotactic devices in hand, …

Fuel-Free Light-Powered TiO2/Pt Janus Micromotors for Enhanced Nitroaromatic Explosives Degradation

Nitroaromatic explosives such as 2,4,6-trinitrotoluene (2,4,6-TNT) and 2,4-dinitrotoluene (2,4-DNT) are two common nitroaromatic compounds in ammunition. Their leakage leads to serious environmental pollution and threatens human health. It is important to remove or decompose them rapidly and efficiently. In this work, we present that light-powered TiO2/Pt Janus micromotors have high efficiency for the “on-the-fly” photocatalytic …
