Poisoning of bubble propelled catalytic micromotors : the chemical environment matters
Self-propelled catalytic microjets have attracted considerable attention in recent years and these devices have exhibited the ability to move in complex media. The mechanism of propulsion is via the Pt catalysed decomposition ...
Macroscopic self-propelled objects
Self-propelled systems are currently in the spotlight of the research community. We review the progress of the construction of both millimeter- and centimeter-sized self-propelled macroscopic objects. We will also discuss ...
Self-propelled nanojets via template electrodeposition
In this paper, we present a rapid, high-yield, low-end and low-cost fabrication of nanojet motors using a template directed electrochemical deposition method. Using an electrochemical deposition method, the bubble-ejecting ...
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 ...
Concentric bimetallic microjets by electrodeposition
Self-propelled micro and nanosystems are at the forefront of nanotechnology research. Here we describe a method for fabrication of concentric bimetallic microjets via an electrochemical deposition route. These microjet ...
Graphenes prepared by Staudenmaier, Hofmann and Hummers methods with consequent thermal exfoliation exhibit very different electrochemical properties
Large-scale fabrication of graphene is highly important for industrial and academic applications of this material. The most common large-scale preparation method is the oxidation of graphite to graphite oxide using ...
Inherently electroactive graphene oxide nanoplatelets as labels for single nucleotide polymorphism detection
Graphene materials are being widely used in electrochemistry due to their versatility and excellent properties as platforms for biosensing. However, no records show the use of inherent redox properties of graphene 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.
Reynolds numbers exhibit dramatic influence on directionality of movement of self-propelled systems
Self-propelled artificial objects are at the current forefront of research. We demonstrate here that the motion directionality of millimetre sized self-propelled objects is highly dependent on the Reynolds numbers (Re) of ...
