Probing Mechanism and Transition State of RNA Refolding

Kinetics and the atomic detail of RNA refolding are only poorly understood. It has been proposed that conformations with transient base pairing interaction are populated during RNA refolding, but a detailed description of those states is lacking. By NMR an ...

Supertough UV-curable silane/silica gas barrier coatings on polymers

Yves Leterrier, Bandeep Singh, Gil Rochat

Ultra-thin (10–500 nm) photo-polymerized γ-methacryloxypropyltriethoxysilane (MPMS) and vinyltrimethoxysilane (VTS) layers applied to SiO2 coatings on polyethylene terephthalate films improved the oxygen barrier performance of the oxide coated films by mor ...

First-Principles Study of Non-heme Fe(II) Halogenase SyrB2 Reactivity

Nicola Marzari

We present here a computational study of reactions at a model complex of the SyrB2 enzyme active site. SyrB2, which chlorinates L-threonine in the syringomycin biosynthetic pathway, belongs to a recently discovered class of alpha-ketoglutarate (alpha KG), ...

Pd Nanoparticles in a Supported Ionic Liquid Phase: Highly Stable Catalysts for Selective Acetylene Hydrogenation under Continuous-Flow Conditions

Paul Joseph Dyson, Lioubov Kiwi, Gabor Laurenczy, Marina Ruta

Monodispersed Pd nanoparticles of 5 and 10 nm were obtained via reduction of Pd(acac)2 dissolved in ionic liquid (IL), [bmim][PF6], or [bmimOH][TF2N], supported on carbon nanofibers (CNF) anchored to sintered metal fibers (SMF). Using [bmimOH][TF2N], the m ...

Fast temperature cycling of the catalytic CO oxidation using microstructure reactors

Martin Luther

The possibility to increase the performance (productivity or selectivity) of a chemical reactor by using periodic variations of reaction parameters (e.g. reactant concentration or temperature) has been theoretically envisaged since the beginning of the 70t ...

Three-Phase Catalytic Hydrogenation of a Functionalized Alkyne: Mass Transfer and Kinetic Studies with in Situ Hydrogen Monitoring

Albert Renken, Lioubov Kiwi, Martin Grasemann

Systematic studies of mass transfer interactions with intrinsic reaction kinetics were performed for the threephase selective hydrogenation of 2-methyl-3-butyn-2-ol (MBY) to 2-methyl-3-buten-2-ol (MBE) over a modified Pd/CaC

Effect of Lewis acids on the Diels-Alder reaction in ionic liquids with different activation modes

Paul Joseph Dyson, Ana Vidis

The Diels-Alder reaction has been examd. in room temp. ionic liqs. with high molar concns. of Lewis acids under various conditions. A molar ratio of 10% catalyst gave a large increase in the selectivity and the yield of the reaction. The effect of catalyst ...

Features of a twin-arginine signal peptide required for recognition by a Tat proofreading chaperone

Julien Maillard

The twin-arginine translocation (Tat) system is a bacterial protein targeting pathway. Tat-targeted proteins display signal peptides containing a distinctive SRRxFLK ‘twin-arginine’ motif. The Escherichia coli trimethylamine N-oxide reductase (TorA) bears ...

Synthesis of monodispersed palladium nanoparticles to study structure sensitivity of solvent-free selective hydrogenation of 2-methyl-3-butyn-2-ol

Albert Renken, Lioubov Kiwi, Danièle Laub

A novel method for isolation of monodispersed Pd nanoparticles from a reverse microemulsion was developed using hydrocarbon evaporation and methanol-assisted particle purification from a surfactant. Fcc Pd nanoparticles of 6, 8, 11, and 13 nm in diameter w ...

Selectivity of montmorillonite catalyzed prebiotic reactions of D, L-nucleotides

The montmorillonite-catalyzed reactions of the 5′-phosphorimidazolides of D, L-adenosine (D, L-ImpA) (Figure 1a. N = A, R = H) and D, L-uridine (Figure 1a., N = U, R = H) yields oligomers that were as long as 7 mers and 6 mers, respectively. The reactions ...
