Dielectric properties of silver nanoparticles coated with silica shells of different thicknesses

Heinrich Hofmann, Jose Enrico Quijano Quinsaat

Core/shell nanoparticles having metallic silver nanoparticle cores of similar to 38 nm in diameter and silica shells of different thicknesses ranging from similar to 3.6-20 nm were prepared. For the silica coating, a slightly modified Stober method was use ...

Impact of He and Cr on defect accumulation in ion-irradiated ultrahigh-purity Fe(Cr) alloys

Robin Schäublin, Amuthan Ramar, Anna Prokhodtseva

The effect of He on the primary damage induced by irradiation in ultrahigh-purity (UHP) Fe and Fe(Cr) alloys was investigated by transmission electron microscopy (TEM). Materials were irradiated at room temperature in situ by TEM in a microscope coupled to ...

Multiscale phase mapping of LiFePO4-based electrodes by transmission electron microscopy and electron forward scattering diffraction

Cyril Cayron

LiFePO4 and FePO4 phase distributions of entire cross-sectioned electrodes with various Li content are investigated from nanoscale to mesoscale, by transmission electron microscopy and by the new electron forward scattering diffraction technique. The distr ...

Electron energy loss spectroscopy investigation through a nano ablated uranium dioxide sample

A lamella of uranium dioxide (similar to 10 x similar to 10 x similar to 0.02-0.20 mu m) was produced by focused ion beam for transmission electron and electron energy loss spectroscopy (EELS) examinations. This sample allows quantitative analysis of the E ...

Effect of fuels on combustion synthesis of TiO2 - Towards efficient photocatalysts for methylene blue oxidation and Cr (VI) reduction under natural sunlight

Nicolas Xanthopoulos

A facile synthesis of carbon and nitrogen co-doped nano-TiO2 with pure anatase phase and high surface area was achieved by using combustion synthesis without the need of surfactants in a single step approach. Organic fuels such as hexamine, triethyl amine ...

Nanoindentation cracking in gallium arsenide: Part I. In situ SEM nanoindentation

Johann Michler, Jacques Giovanola, Jean-Marc Breguet, Cédric Pouvreau

The nanoindentation fracture behavior of gallium arsenide (GaAs) is examined from two perspectives in two parent papers. The first paper (part I) focuses on in situ nanoindentation within a scanning electron microscope (SEM) and on fractographic observatio ...

Hepatitis B subvirus particles display both a fluid bilayer membrane and a strong resistance to freeze drying: a study by solid-state NMR, light scattering, and cryo-electron microscopy/tomography

Paul Guichard

Hepatitis B surface antigen (HBsAg) subvirus particles produced from yeast share immunological determinants with mature viruses, which enable the use of HBsAg as a potent antigen for human vaccination. Because the intimate structure of such pseudoviral par ...

The physics and micro-mechanics of nano-voids and nano-particles in polymer combinations

In this article the role of voids or particulate inclusions of different sizes on mechanical properties and particularly on toughness in several polymers is discussed. With decreasing void sizes and intervoid distances, the influence of the interphase mate ...

Microstructure and mechanical properties of a W-2wt.%Y2O3 composite produced by sintering and hot forging

Philippe Spätig, Nadine Baluc, Robin Schäublin

A W-2Y(2)O(3) composite has been developed by powder metallurgy methods in collaboration with the Plansee Company (Austria). The microstructure of the composite was analyzed using transmission electron microscopy and electron backscatter diffraction in sca ...

Biomineralization in living hypercalcified demosponges: Toward a shared mechanism?

Melany Melissa Gilis

Massive skeletons of living hypercalcified sponges, representative organisms of basal Metazoa, are uncommon models to improve our knowledge on biomineralization mechanisms and their possible evolution through time. Eight living species belonging to various ...
