This work reports the synthesis and materials characterization of novel heterogeneous nanostructures consisting of zinc oxide (ZnO) nanowires and silicon (Si) nanocrystals. Hydrothermal and non-thermal plasma synthesis techniques were utilized to create ZnO nanowires and Si nanocrystals, respectively. The heterostructures of ZnO nanowires and Si nanocrystals were formed and characterized using scanning...
This paper reports a novel fabrication technique to create pollutant-degrading, self-propelled, micro soft-robots whose surface is decorated with the high surface-area, photocatalytic ZnO nanowire array. Micromotors/microrobots with photodegradation capabilities have been reported [1], but their form is limited to spherical particles with some functional coatings (e.g. Pt for bubble-generation reactions)...
The photocurrent at graphene/metal junctions under femtosecond laser excitation is found to have its polarity fully determined by asymmetry in the electron-hole mobility; this suggests the existence of unexpected lateral photo-Dember effect in graphene.
In this paper, a mathematical model of dynamic task schedule based on an anytime algorithm is proposed. The factors that affect the task deadline of opponents are studied. We construct the mathematical model according to minimize of surplus threat and maximize of attack value. By using the task deadline and time utility the model can give the decisions timely and coordinately for known and unknown...
