Homogeneously dispersed organic–inorganic hybrid nanocomposites can be obtained by increasing the interfacial interactions between both components via formation of hydrogen bonds or covalent bonds, mixing various polymers adequate choice inorganic precursors. The mechanical response these advanced functional materials is an issue paramount importance when industrial applications are targeted. Large progress in understanding properties O–I hybrids has been gained testing under different...
We report experimentally the dynamic properties of entry and transport unfolded native proteins through a solid-state nanopore as function applied voltage, we discuss experimental data obtained compared to theory. show an exponential increase in event frequency current blockades decrease times electric driving force. The normalized blockage ratio remains constant or decreases for folded proteins, respectively, transmembrane potential. protein is stretched under dwell time compact pore almost...
Coherent x-ray diffractive imaging is a powerful method for studies on nonperiodic structures the nanoscale. Access to femtosecond dynamics in major physical, chemical, and biological processes requires single-shot diffraction data. Up now, this has been limited intense coherent pulses from free electron laser. Here we show that laser-driven ultrashort sources offer comparatively inexpensive alternative. We present measurements of patterns isolated nano-objects with single 20 fs pulse...
We use solid-state nanopores to study the dynamics of single electrically charged colloids through as a function applied voltage. show that presence colloid inside pore changes resistance, in agreement with theory. The normalized ionic current blockade increases voltage and remains constant when electrical force even more. observe short long events blockades. Their durations are associated, respectively, low high variation. ratio force. frequency exponentially saturates at dwelling time...
The main objective of this work is the preparation decorative zirconium oxynitride, ZrOxNy, thin films by dc reactive magnetron sputtering. Film properties were analyzed as a function gas flow and correlated with observed structural changes. Measurements showed systematic decrease in deposition rate increase revealed three distinct modes: (i) metallic mode, (ii) transition mode (subdivided into zones), (iii) an oxide mode. measurements target potential also consistent these changes,...
Using scanning near-field optical microscopy, we investigate the ability of nanoslits in metallic films to launch surface plasmon polaritons (SPPs) under highly oblique incidence at λ=975 nm. The SPP generation efficiency is inferred by fitting recorded data with a simple analytical model. We find remarkably large 20% for front side slit, which agreement recent theoretical predictions relying on fully vectoral electromagnetic formalism. An even larger predicted experimentally (44%) and...
Fe-bearing clay minerals contain structural iron that can be redox-active and participate in electron transfer reactions with aqueous species. Although these redox properties have been studied extensively the past decade, questions remain about respective roles of kinetic thermodynamic constraints establishing steady-state conditions. In this study, reduction kinetics Cr(VI) to Cr(III) by Fe(II) contained structure reduced ferruginous samples (reference Nontronite NAu-1) was monitored...
We have developed on the DIFFABS-SOLEIL beamline a biaxial tensile machine working in synchrotron environment for situ diffraction characterization of thin polycrystalline films mechanical response.
