Therefore, for the practical use of Pd-based nanomaterials at the cathode of direct liquid fuel cells, it is necessary to maximize the activity of them by engineering their structure, morphology and/or composition. Bimetallic nanoparticles with a core-shell structure are a type of conventional ...
Although quantitative evaluations are not possible because there is no direct method to quantify the apolar and polar inter- actions in this complex multicomponent system with likely interfacial segregation of some components, the qual- itative picture is fairly clear. According to equation (2),...
controlling fabrication parameters, the addition of favorable dopants during the fabrication of the bulk implant, and the application of fruitful surface modification technologies, have been proposed to overcome these drawbacks14,15,16,17,18. The surface finishing of NiTi implant with CaP family, in ...
In general, electrocatalytic systems have a more compact and flexible structure compared to photocatalytic systems. They also have higher catalytic efficiency due to the continuous transfer of electrons to the working electrode driven by an external bias. Nevertheless, the direct redox reaction on the...
The oCVD process for depositing thin films of PEDOT was demonstrated for various light trapping photovoltaic architectures. For texturing at a single interface, it was shown that PEDOT is able to fully fill in features of varying shapes and feature sizes as low as 50 nm. For thinner layers, ...
Gravity-induced convection has significant effect on mass transport during metal electrodeposition. The effects of gravity-induced convection on deposit structure and kinetic behavior of metal electrodeposition were studied. It was found that copper powders and copper foils were easily electrodeposited by ...

Both calcium phosphate and Fe-rich clay occur in direct contact with the cell wall, and are inter-grown both within and outside the cell. Quartz occurs outside the cell (black area in (e)) where the cell wall is more poorly preserved. labile wall layers, coatings of exopolymeric ...
Selective targeting plus optimal biocompatibility is still a big challenge in nanomedicine. Although many nanomaterials including graphene oxide (GO) and molybdenum disulfide (MoS2) have been tested for this purpose, these materials possess both favorabl
