Hierarchical Nanoporous Gold-Platinum with Heterogeneous

Figure 2: XRD patterns of pure NPG and HiNAP-3 films.

The indices of crystal face corresponding to Pt and Au are marked.

More interestingly, three dimensional porous channels are embedded within Pt-NPs, so that large surface-to-volume ratio and Pt-Au interfaces can be created [see Fig. 1 (d, e) in white ellipses]. Therefore, these hybrid nanostructures might be the good candidates for electrochemical catalysts. Electrochemical performances of the NPG and HiNAP films are evaluated by cyclic-voltammetry (CV) in the H2SO4 aqueous solution. Commercial Pt plate is also tested for comparison. As shown in Fig. 3(a), the well-defined hydrogen desorption/adsorption peaks from Pt are observed in the potential region from −0.2 to 0 V for HiNAP-3 and commercial Pt plate, and these characters are consistent with the previous investigations. eover, the quasi-reversible oxidation/reduction peaks are observed in the potential range from 0.3 to 1.0 V, which are associated with the Au/Pt oxidation and reduction in aqueous solution.

(a) Representative CV curves in 0.5 M H2SO4, and the current density are normalized by the geometrical scale of the working electrode. The inset presents the reduction peaks of Au-oxide for each sample. (b) CV curves of HiNAPs in 0.5 M H2SO4 + 1 M CH3OH and the current densities are normalized by the electrochemical active surface area calculated based on the CV curves in the H2SO4. The data from bare nanoporous gold and commercial Pt plate is included for comparison. Scan rate: 50 mV/s.

Is what we see based on what we believe?

by PositiveOption

Because I believe
1 Corinthians 3:19 For the wisdom of this world is foolishness with God. For it is written, He taketh the wise in their own craftiness.
That means I see that, because the cell's nanotechnology and complexity on multiple levels is unmatched by all the engineers on the earth combined, it is a paradox if it comes from a natural cause
But Science does not they say there two ways to get a efficient design?
1.Designers apply their energy and intelligence to trial and error and create a efficient design like the motor of the space shuttle
2

It is a trust in knowlede and it's source

One who loves God will see what they believe and the ones who trust science will believe what they see

Nanotechnology is not ready . how about

by bionecr

People move some of their interest to something that could be ready sooner. Nanotechnology has been given alot of press, and that may have caused us to over look the possibilities of accupuncture. Or most people are idiots and a small percentage of us do most of the creative thinking Why havent we brought the technique of accupuncture into the 21st century. Hollow micro needles delivering anti biotics to localized areas of the body, or chemotherapy delivered into the closest cappilaries. Such a waste of accupuncturists today. What if this technique were used in areas around the lungs for tuberculosis would we have cleared up infections with less risk of creating drug esistant strains

Nanotubes Increase Solar PV Conductivity 100 Million-Fold  — Sourceable
Carbon-based nanostructures are already being used as materials in solar cells with increasing frequency, yet their ability to enhance electrical performance has thus far been hampered by limited ability to assemble orderly networks using the materials.
