We have investigated the p- and n-type dopants in thin SGOI (20 nm) material obtained by Ge enrichment. The samples are doped with either BF2 or arsenic or phosphorus and then annealed with either a spike or a 15 s rapid thermal annealing in a temperature ...
Mon projet consiste à trouver une topologie optimale pour alimenter par induction des périphériques de bureau tel que souris, écran ou clavier. Dans ce projet, nous allons étudier seulement deux topologies d’onduleurs: · Une constituée d’un seul transistor ...
A detailed budget of the fluxes of bio-available phosphorus (bio-P) was established for the ultra-oligotrophic Lake Brienz (Switzerland) and its catchment. Lake Brienz is a cold, deep oligotrophic peri-alpine lake that receives an annual load of approximat ...
The synthesis and characterization of several new phosphorus-containing partially lower rim substituted derivatives of 5,11,17,23-tetra(t-butyl) calix(4)arene (1) and 5,11,17,23-tetra(t-octyl)calix(4)arene (II), namely 5,11,17,23-tetra(t-butyl)-25,27-dihyd ...
Dispersion-corrected atom-centered; potentials (DCACPs) for the element phosphorus were generated and tested for the BLYP, BP, and PBE generalized gradient approximations of the exchange-correlation functional. The accuracy and transferability of the DCACP ...
Microstructure and chemical composition of the hard Ni–P–Ti layer formed on the Ti–6Al–4V alloy after duplex surface treatment were investigated by light microscopy, X-ray diffraction, scanning electron microscopy and analytical/high resolution transmissio ...
We investigated the interactions of dissolved reactive phosphorus (DRP) and dissolved nonreactive phosphorus (DNRP) with suspended and settled aquatic particles. The sorption to minerogenic particles from an alpine catchment collected in rivers, hydropower ...
Lake Prespa and Lake Ohrid, located in south-eastern Europe, are two lakes of extraordinary ecological value. Although the upstream Lake Prespa has no surface out flow, its waters reach the 160 m lower Lake Ohrid through underground hydraulic connections. ...
We present a systematic study of metal-organic honeycomb lattices assembled from simple ditopic molecular bricks and Co atoms on Ag(111). This approach enables us to fabricate size- and shape-controlled open nanomeshes with pore dimensions up to 5.7 nm. Th ...
There are few data on the effect of long-term manipulations on soil protozoa, and almost nothing is known about soil protozoa in Alaska. I studied the response of testate amoebae to nitrogen and phosphorus addition in an Arctic fen, at Toolik Lake Long-Ter ...
