Foam, fleece and honeycomb supports for platinum nanoparticles

Sara Coles is a guest web-writer for Catalysis Science & Technology. She
currently works for Johnson Matthey in Royston, UK.

Foam, fleece and honeycomb have one unexpected thing in common: they are all physical structures that can be made into supports for industrial platinum catalysts.

Their technique allows higher platinum loadings to be applied without the disadvantages of agglomeration and adhesion, meaning that higher catalytic activities can be achieved on low surface area substrates.

This could have potential to expand the use of monolithically supported platinum catalysts beyond their automotive niche and into wider industrial use for reactions such as methanol steam reforming, oxidative dehydrogenation of propane and liquid phase hydrogenations. The advantages of monolithic catalysts over their classic pellet bed alternatives include lower pressure drops and improved mass transfer.

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

Nanotechnology is not ready . how about

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.
