Determining the Surface Structure of Silicated Alumina Catalysts via Isotopic Enrichment and Dynamic Nuclear Polarization Surface-Enhanced NMR Spectroscopy

David Lyndon Emsley, Brennan James Walder, Jasmine Viger-Gravel

Isotopic enrichment of Si-29 and DNP-enhanced NMR spectroscopy are combined to determine the detailed surface structure of a silicated alumina catalyst. The significant sensitivity enhancement provided by DNP is vital to the acquisition of multinuclear and ...

Ketenimines from Isocyanides and Allyl Carbonates: Palladium-Catalyzed Synthesis of β,γ-Unsaturated Amides and Tetrazoles

Qian Wang, Jieping Zhu, Mathias Mamboury, Guanyinsheng Qiu

The reaction of allyl ethyl carbonates with isocyanides in the presence of a catalytic amount of Pd(OAc)2 provided ketenimines through b-hydride elimination of the allyl imidoylpalladium intermediates. The insertion of the isocyanide into the p-allyl Pd co ...

Quantification of Bulk Densification in Fused Silica Induced by Femtosecond Laser Exposure in the Sub-50 fs Regime

Yves Bellouard

Using micro-cantilever deflection, we study laser-induced densification in bulk fused silica in the sub-50 fs, non-ablative regime. We estimate induced densification from deflection measurements, with a maximum value of 0.014%. ...

Investigation of the micro-mechanical properties of femtosecond laser-induced phases in amorphous silica

Yves Bellouard, Christos Edouardos Athanasiou

Femtosecond pulses used in the regime where self-organized patterns are found have two noticeable effects in amorphous silica's (a-SiO2) optical and chemical properties: The decrease of the material's refractive index as well as an enhanced etching selecti ...

Silaffins in Silica Biomineralization and Biomimetic Silica Precipitation

Carolin Christine Lechner

Biomineralization processes leading to complex solid structures of inorganic material in biological systems are constantly gaining attention in biotechnology and biomedical research. An outstanding example for biomineral morphogenesis is the formation of h ...

Polymer Adsorption on Iron Oxide Nanoparticles for One-Step Amino-Functionalized Silica Encapsulation

Heinrich Hofmann, Lionel André Maurizi

This paper presents an original method to obtain, in one step, core/shell nanoparticles grafted covalently with polymer and functionalized with amino groups. By combining polyvinyl alcohol (PVA) and silica precursors, we were able to obtain silica-coated a ...

Controlling Mesopore Size and Processability of Transparent Enzyme-Loaded Silica Films for Biosensing Applications

Bernard Wenger, Heinrich Hofmann, Raphaël Pugin, Oswaldo Javier Pérez Anguiano, Emmanuel Scolan

Silica-based nanoporous thin films including large mesopores are relevant as enzyme supports for applications in biosensing. The diffusion and immobilization of large biomolecules such as enzymes in such porous films require the presence of large mesopores ...
