Alumina nanotubes (ANTs) with unique fusiform morphologies were synthesized via a simple electrochemical route; the fluctuation of the electronic current density during the anodization process is considered to be the main reason for the formation of such new alumina nanostructures. 相似文献

CO poisoning during methanol electrooxidation was investigated on PtAu alloys with different surface compositions. Results show that the CO formation can be reduced gradually with increasing surface Au fractions in PtAu alloys and CO poisoning can be almost eliminated by adjusting to a proper surface Au fraction. 相似文献

Binary nanoassembly was realized by mixing gold@polyaniline nanoparticles with diblock copolymers in the DMF/H(2)O system and the products present a controlled transformation from symmetrical shells into spatially distributed petal-like polymer shells on gold cores. 相似文献

Nanostructured materials are a new class of enzyme mimics, the inhibitors of which have not been studied. Herein, we demonstrate the screening of inhibitors for Au@Pt nanorod (NR) oxidase mimics. In addition, based on the enzyme inhibition reaction, determination of "poisoning" inhibitors is demonstrated. 相似文献

The morphology, thermal degradation, and flame retardancy of epoxy (EP) composites containing microcrystalline cellulose whisker
(MCW) and microencapsulated ammonium polyphosphate (MFAPP) were investigated using optical microscopy, limiting oxygen index
(LOI), UL-94, thermogravimetry (TG), microscale combustion calorimeter, and TG-FTIR. EP/MFAPP/MCW composites can pass V-0
in UL-94 test at 6 wt% loading, and its peak heat release rate decreases when compared with EP and EP/MFAPP. The reason is
that the presence of MCW strengthens the charring capacity of EP composites in a fire. The results of TG and TG-FTIR show
that at low temperature, MFAPP stimulates the dehydration of MCW and EP, and produces gas which is helpful for the formation
of an intumescent char. Moreover, the residue at high temperature does not release any flammable gas and is a good insulation
layer on the surface of the sample, which protects the underlying material in a fire. 相似文献
