When silicon thin films are deposited by plasma enhanced chemical vapor deposition in a plasma regime close to the formation of powder, a new type of material, called hydrogenated polymorphous silicon (pm-Si:H) is obtained. This material has increased tran ...
[1] We present new measurements of Os-186/Os-188 and Os-187/Os-188 in 10 Os-rich platinum group element (PGE) alloys from placer deposits formed by the mechanical erosion of peridotite-bearing ophiolites in the Klamath and Siskiyou Mountains in northern Ca ...
Light Induced Chemical Vapour Deposition (LICVD) of titanium dioxide thin films is studied in this work. It is shown that this technique enables to deposit locally and selectively a chosen crystalline phase with a precise controlled thickness at low substr ...
A comparative characterization of crystal structure, morphology, sizes, and orientation in Ca phosphate precipitation from aqueous solutions, the mineral phase in bones, and mineral deposits on cardiac valves has been performed by high-resolution transmiss ...
Electron Beam Induced Deposition (EBID) allows deposition of three-dimensional micro- and nano-structures of conductive and insulating materials on a wide range of substrates. The process is based on the decomposition of molecules of a pre-selected precurs ...
The limited electrode density and thus, the limited spatial resolution of substrate-integrated microelectrodes arrays (MEAs) used in in-vitro electrophysiology are currently considered as the main constraints of this technique. By taking advantage of the c ...
In this paper we describe the fabrication of a two-dimensional photonic band gap structure by focused electron beam induced deposition. Structure geometry is computed in order to create a light-trapping effect at 632 nm wavelength. Deposits produced using ...

Two methods were used for the deposition of Pt particles on synthetic B-doped diamond (BDD) surfaces: chem. deposition and electrodeposition under potentiostatic conditions. However, electrodeposition leads much higher Pt dispersion than chem. deposition. ...
Iridosmine grains from placer deposits associated with peridotite-bearing ophiolites in the Klamath mountains have extremely radiogenic Os-186/Os-188 ratios and old Re-Os minimum ages, from 256 to 2644 million years. This indicates the existence of an anci ...
