Abstract

In studies that mimic natural photosynthesis, a system containing three inde-pendent components, a photosensitizer, electron relay, and catalyst, has been used with a sacrificial electron donor. In this study, we created a novel system for the photocatalytic generation of NADH from aqueous protons using only Pt nanoparticles without any additional photosensitizer, electron relay, and homogeneous organometallic catalyst. We found that irradiation of the Pt nanoparticle solution with visible light converts NAD+ to NADH with a high yield of 86% in the presence of triethanolamine as a sacrificial electron donor. The rate of NADH photogeneration depended on the concentration of PtNPs and TEOA. The rate of NADH generation also increased with NAD+ concentration at low values and reached a plateau.

    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.
