Leather-Promoted Transformation of Glucose into 5-Hydroxymethylfurfural and Levoglucosenone

Paul Joseph Dyson, Felix Daniel Bobbink, Zhangjun Huang, Florent Menoud

The search for efficient catalysts frequently leads to new homogeneous and heterogeneous catalysts of increasing complexity, and sometimes common, natural, or hybrid natural/synthetic materials that could be used in catalysis are overlooked. For example, t ...

Chromate tolerance and removal of bacterial strains isolated from uncontaminated and chromium-polluted environments

Rizlan Bernier-Latmani, Zuzana Chromiková

Investigation of bacterial chromate tolerance has mostly focused on strains originating from polluted sites. In the present study, we isolated 33 chromate tolerant strains from diverse environments harbouring varying concentrations of chromium (Cr). All of ...

A Precious Catalyst: Rhodium-Catalyzed Formic Acid Dehydrogenation in Water

Gabor Laurenczy, Cornel Fink

The performance of rhodium complex [Cp*Rh(bis(pyrazol-1-yl)methane)Cl]Cl was evaluated for formic acid dehydrogenation in aqueous solution. Solid-state X-ray diffraction helped to confirm the catalyst structure. Multinuclear NMR spectroscopy was employed t ...

Radiation enhanced oxidation of proton-irradiated copper thin-films: Towards a new concept of ultra-high radiation dosimetry

Jean-Michel Sallese, Didier Bouvet, Georgi Gorine

The effects of extreme radiation levels on the electrical resistivity of metal thin films made of copper were studied by means of electrical measurements and post irradiation imaging. Different 3x3 mm(2) chips were produced by depositing 500 nm of meander ...

Chromate Resistance Mechanisms in Leucobacter chromiiresistens

Rizlan Bernier-Latmani, Elena Suvorova Buffat

Chromate is one of the major anthropogenic contaminants on Earth. Leucobacter chromiiresistens is a highly chromate-resistant strain, tolerating chromate concentrations in LB medium of up to 400 mM. In response to chromate stress, L. chromiiresistens forms ...

Design of Separated Element Reflector Experiments in CROCUS: PETALE

Andreas Pautz, Mathieu Hursin, Vincent Pierre Lamirand, Pavel Frajtag, Daniel Jerôme Siefman

The present article describes the preliminary design studies for PETALE (Programme d'Etude en Transmission de l'Acier Lourd et ses Elements), an oncoming experimental program in the CROCUS reactor. Within the framework of the Venus-Eole-Proteus collaborati ...

Highly Active Nanoperovskite Catalysts for Oxygen Evolution Reaction: Insights into Activity and Stability of Ba0.5Sr0.5Co0.8Fe0.2O2+delta and PrBaCo2O5+delta

Nicola Marzari

It is shown that producing PrBaCo2O5+delta and Ba0.5Sr0.5Co0.8Fe0.2O2+delta nanoparticle by a scalable synthesis method leads to high mass activities for the oxygen evolution reaction (OER) with outstanding improvements by 10x and 50x, respectively, compar ...

Lattice-mediated magnetic order melting in TbMnO3

Fabrizio Carbone, Edoardo Baldini

Recent ultrafast magnetic-sensitive measurements [Johnson et al., Phys. Rev. B 92, 184429 (2015); Bothschafter et al., Phys. Rev. B 96, 184414 (2017)] have revealed a delayed melting of the long-range cycloid spin order in TbMnO 3 following photoexcitation ...

Gold-catalyzed domino cyclization-alkynylation reactions with EBX reagents: new insights into the reaction mechanism

Jérôme Waser, Paola Caramenti, Yifan Li

Gold-catalyzed domino processes constitute a useful alternative to C-H functionalization for the synthesis of functionalized (hetero)arenes. Herein, we report computational studies on the gold-catalyzed cyclization alkynylation of keto-allenes with ethynyl ...

Imaging magnetic vortex configurations in ferromagnetic nanotubes

Anna Fontcuberta i Morral, Dirk Grundler, Gözde Tütüncüoglu

We image the remnant magnetization configurations of CoFeB and permalloy nanotubes (NTs) using x-ray magnetic circular dichroism photoemission electron microscopy. The images provide direct evidence for flux-closure configurations, including a global vorte ...
