Producing concentrated solutions of monosaccharides using biphasic CO2–H2O mixtures
Sustainably producing concentrated solutions of monosaccharides from biomass is a key challenge facing the conversion of lignocellulosic biomass to biofuels or bioproducts. Most pretreatment and enzymatic hydrolysis processes are run at low-solid concentra ...
2012Grafting submicron titania particles with gold nanoparticles using droplet microfluidics
Martinus Gijs, Virendra Kumar Parashar, Josias Basil Wacker
A microfluidic method to synthesize gold–titania nanocomposites is presented. Porous TiO2 particles are first loaded with a reducing agent and then suspended in water and mixed with chloroauric acid (HAuCl4) in a droplet-by-droplet manner on a microfluidic ...
2012In situ time-resolved DXAFS study of Rh nanoparticle formation mechanism in ethylene glycol at elevated temperature
A combination of in situ time-resolved DXAFS and ICP-MS techniques reveals that the formation process of Rh nanoparticles (NPs) from rhodium trichloride trihydrate (RhCl3 center dot 3H(2)O) in ethylene glycol with polyvinylpyrrolidone (PVP) at elevated tem ...
2012Formic acid as a hydrogen source – recent developments and future trends
Gabor Laurenczy, Martin Grasemann
Formic acid has recently been suggested as a promising hydrogen storage material. The basic concept is briefly discussed and the recent advances in the development of formic acid dehydrogenation catalysts are shown. Both the state of research for heterogen ...
Royal Soc Chemistry2012Gold nano-particles supported on hematite and magnetite as highly selective catalysts for the hydrogenation of nitro-aromatics
Lioubov Kiwi, Fernando Cardenas Lizana
The catalytic action of nano-sized Au particles supported on hematite (Fe2O3) and magnetite (Fe3O4) is compared in the continuous gas phase hydrogenation of p-chloronitrobenzene and m-dinitrobenzene. The catalysts were prepared by deposition-precipitation ...
2012Single Molecule Detection of Nitric Oxide Enabled by d(AT)15 DNA Adsorbed to Near Infrared Fluorescent Single-Walled Carbon Nanotubes
We report the selective detection of single nitric oxide (NO) mols. using a specific DNA sequence of d(AT)15 oligonucleotides, adsorbed to an array of near-IR fluorescent semiconducting single-walled carbon nanotubes (AT15-SWNT). While SWNT suspended with ...
2011Striking Influence of the Catalyst Support and Its Acid–Base Properties: New Insight into the Growth Mechanism of Carbon Nanotubes
Arnaud Magrez, Gabor Laurenczy, Endre Horvath, Jin Won Seo, Rita Smajda, Donatello Acquaviva, Juan Carlos Andresen
In the accepted mechanisms of carbon nanotube (CNT) growth by catalytic chemical vapor deposition (CCVD), the catalyst support is falsely considered as a passive material whose only role is to prevent catalytic particles from coarsening. The chemical chang ...
2011Photocatalytic activity of TiO2/SWCNT and TiO2/MWCNT nanocomposites with different carbon nanotube content
László Forró, Arnaud Magrez, Klara Hernadi
With different mass ratios, titanium dioxide/carbon nanotube (0.1-10 wt% CNTcontent) nanocomposites were prepared with the aid of ultrasonication method. The structures of the various TiO2/CNT nanocomposites were characterized by electron microscopy (scann ...
2011Copper-Catalyzed Tyrosine Nitration
Hubert Girault, Liang Qiao, Yu Lu
Tyrosine nitration, often observed during neurodegenerative disorders under nitrative stress, is usually considered to be induced chemically either by nitric oxide and oxygen forming nitrogen dioxide or by the decomposition of peroxynitrite. It can also be ...
2011Localized and delocalized Ti 3d carriers in LaAlO3/SrTiO3 superlattices revealed by resonant inelastic x-ray scattering
The important source of interface conductivity in LaAlO3/SrTiO3 heterostructures, the Ti 3d carriers, is probed with resonant inelastic x-ray scattering at the Ti 2p(3/2) edge of epitaxially grown superlattices. We reveal unambiguously the generation of bo ...
