Digital holographic confocal microscope

Demetri Psaltis, Alexandre Goy

We demonstrate experimentally a scanning confocal microscopy technique based on digital holographic recording of the scanned spot. The data collected in this way contains all the information to produce three-dimensional images. Several methods to treat the ...

Performances of Rh and Mo mirrors under JET exposure

The aim of this work was to provide a comprehensive surface characterization of rhodium and molybdenum mirrors exposed on the main chamber wall of JET during campaigns with carbon plasma-facing components. As determined using X-ray photoelectron spectrosco ...

Is EM dead?

Graham Knott

Since electron microscopy (EM) first appeared in the 1930s, it has held centre stage as the primary tool for the exploration of biological structure. Yet, with the recent developments of light microscopy techniques that overcome the limitations imposed by ...

CO2 hydrogenation on a metal hydride surface

Davide Ferri, Shunsuke Kato

The catalytic hydrogenation of CO 2 at the surface of a metal hydride and the corresponding surface segregation were investigated. The surface processes on Mg 2NiH 4 were analyzed by in situ X-ray photoelectron spectroscopy (XPS) combined with thermal deso ...

Desorption of alkali atoms from 4He nanodroplets

Marcel Drabbels, Evgeniy Loginov, Marina Langlet

The dynamics following the photoexcitation of Na and Li atoms located on the surface of helium nanodroplets has been investigated in a joint experimental and theoretical study. Photoelectron spectroscopy has revealed that excitation of the alkali atoms via ...

A vibration suppression approach to high-speed atomic force microscopy

Georg Fantner

The possibility of many new applications and novel scientific observations can be provided by efficient and reliable high-speed atomic force microscopy techniques. However, the reliability of the AFM images decreases significantly as the imaging speed is i ...

Scanning Near-Field Optical Microscopy of Living Cells in Liquid, Elaboration of New SNOM Probes and Detection Methods

Kanat Dukenbayev

The aim of the present PhD thesis is the elaboration of new, home-made Scanning Near-field Optical Microscope (SNOM or NSOM), and the demonstration of its great potential for high-resolution topography and fluorescence investigations of soft and solid samp ...

Photocatalytic evaluation of TiO2/nylon systems prepared at different impregnation times

César Pulgarin, Juan Kiwi

TiO2/nylon fabrics were investigated for methanol degradation under UV light irradiation. TiO2 Degussa P-25 was supported on nylon by immersing the nylon in sol-gel TiO2 and silicone. The TiO2 layers on the nylon were explored as a function of the time of ...

Beyond the lateral resolution limit by phase imaging

Christian Depeursinge, Muhammed Fatih Toy, Yann Jérôme Michel Pascal Cotte

We present a theory stating how to overcome the classical Rayleigh-resolution limit. It is based upon a new resolution criterion in phase of coherent imaging process and its spatial resolution is thought to be only SNR limited. Recently, the experimental o ...
