Noble metal (Pd, Ru, Rh, Pt, Au, Ag) doped graphene hybrids for electrocatalysis
Metal decorated graphene materials are highly important for catalysis. In this work, noble metal doped-graphene hybrids were prepared by a simple and scalable method. The thermal reductions of metal doped-graphite oxide ...
Liquid–liquid interface motion of a capsule motor powered by the interlayer Marangoni effect
A novel thin capsule motor has been described in this report. It utilizes the Marangoni effect for the solid capsule to run at a water–oil interlayer, which has not been reported previously. Intrinsic and environment factors ...
Artificial micro-cinderella based on self-propelled micromagnets for the active separation of paramagnetic particles
In this work, we will show that ferromagnetic microjets can pick-up paramagnetic beads while not showing any interaction with diamagnetic silica microparticles for the active separation of microparticles in solution.
Surfactant capsules propel interfacial oil droplets: an environmental cleanup strategy
Invited for this month’s cover is the group of Prof. Martin Pumera from Nanyang Technological University, Singapore. The cover picture shows pristine underwater coral. This image symbolizes the beauty of a clean environment ...
Surfactant capsules propel interfacial oil droplets : an environmental cleanup strategy
Coming clean: Polymer capsules of millimeter dimensions have been loaded with surfactants of negative, positive, or neutral charge, and their influence on the movement of oil droplets at the water/air interface was compared. ...
Biomimetic artificial inorganic enzyme-free self-propelled microfish robot for selective detection of Pb2+ in water
The availability of drinking water is of utmost importance for the world population. Anthropogenic pollutants of water, such as heavy-metal ions, are major problems in water contamination. The toxicity assays used range ...
Blood proteins strongly reduce the mobility of artificial self-propelled micromotors
Autonomous self-propelled catalytic microjets are envisaged as an important technology in biomedical applications, including drug delivery, micro/nanosurgery, and active dynamic bioassays. The direct in vivo application ...
