One-dimensional (1D) ensembles of 2-15 nm diameter gold nanoparticles were prepared using physical vapor deposition (PVD) on highly oriented pyrolytic graphite (HOPG) basal plane surfaces. These 1D Au nanoparticle ensembles (NPEs) were prepared by depositing gold (0.2-0.6 nm/s) at an equivalent thickness of 3-4 nm onto HOPG surfaces at 670-690 K. Under(More)
The H2CO3-HCO3system in vertebrates did not evolve directly from the original forms of life. Organic evolution probably dates back some 109 years.1 Although there may have been small amounts of CO2 present in the atmosphere and CO2 was definitely present in the earth mantle, it is generally accepted that metabolic pathways were anaerobic in nature.
