Seedings of Vicia faba were grown for four weeks at two different light intensities (55 and 105 watts per square meter) in a saline (50 millimolar NaCl) and nonsaline nutrient solution. NaCl salinity depressed growth and restricted protein formation, CO(2) assimilation, and especially the incorporation of photosynthates into the lipid fraction. Conversion of photosynthates in leaves was much mo...

The tunability of the DPIC mechanism. A yellow-emitting coumarin is connected to a “conversion meter” indicating efficiency conversion. needle points at different groups that have been attached pyrrole moiety. These are sorted from left right according conversion yield, with corresponding background ranging dark illustrate photo-bleaching blue photo-conversion. More information can be found in ...

A new route to highly active hopcalite catalysts via flame spray pyrolysis of an inverse microemulsion precursor is reported. The nitrate derived nanoparticles are around 15 nm in diameter and show excellent conversion of CO under ambient conditions, outperforming commercial reference hopcalite materials produced by co-precipitation.

Thin catalyst films with electrocatalytic water oxidation properties similar to those of a recently reported Co-based catalyst can be electrodeposited from dilute Ni(2+) solutions in borate electrolyte at pH 9.2 (B(i)). The Ni-B(i) films can be prepared with precise thickness control and operate at modest overpotential providing an alternative to the Co catalyst for applications in solar energy...

The assimilation of CO(2) by etiolated Hordeum vulgare seedlings during an illumination period indicates a conversion of the organisms to autotrophy.After 1 hour illumination, increases in the photo-assimilation of CO(2) are observed and the distribution of C(14) in the soluble fraction of the plants is predominantly in intermediates of the Calvin cycle.

We have investigated the surface composition of a well-ordered Pt3Sn(111) during CO oxidation with ambient pressure X-ray photoemission spectroscopy. Oxidation tin in coincides onset catalytic conversion, and we observe significant differences state morphology oxide formed depending on gas composition, an oxygen-rich mixture leading to formation 2D wetting layers CO-rich 3D islands.

First principles calculations using density functional theory with corrections for on-site Coulomb interactions (DFT + U) are presented in which we compute the energy for the conversion of CO to CO(2), NO(2) to NO and NO to N(2) over ceria surfaces. The surface sensitivity is discussed on the basis of the vacancy formation energies.

The production of prion particles in vitro by amplification with or without exogenous seed typically results in infectivity titers less than those associated with PrP(Sc) isolated ex vivo and highlights the potential role of co-factors that can catalyze disease-specific prion protein misfolding in vivo. We used a cell-free conversion assay previously shown to replicate many aspects of transmiss...

To facilitate the study of individual metal binding sites of polymeric metalloproteins, conversion of exchange-labile Co(II) in E. coli alkaline phosphatase (EC 3.1.3.1) to exchange-inert Co(III) was examined. Oxidation of Co(II) alkaline phosphatase with hydrogen peroxide results in a single absorption maximum at 530 nm and loss both of the characteristic electron paramagnetic signal and of en...

We present a complete survey of CO (1 → 0) emission in the Local Group dwarf irregular IC 10. The survey, conducted with the BIMA interferometer, covers the stellar disk and a large fraction of the extended H I envelope with the sensitivity and resolution necessary to detect individual giant molecular clouds (GMCs) at the distance of IC 10 (950 kpc). We find 16 clouds with a total CO luminosity...
