Phosphorusinsitudoped (Si1-yCy) films (SiC:P) with substitutional carbon concentration of 1.7% and 2.1% were selectively grown in the source and drain regions of double-gate -oriented (110)-sidewall FinFETs to induce tensile strain in the silicon channel.Insitudoping removes the need for a high-temperature spike annea…
A review of simulation studies of phase equilibria and free energies for systems dominated by coulombic interactions is presented. Phase transitions occur for ionic systems in the strong-coupling limit realized in low-dielectric constant solvents, at low temperatures, or for high charge valences. The majority of simul…
The dynamics of methanol and ethanol molecules confined in MCM-41 with pore diameters d = 2.1, 2.8, and 3.7 nm has been investigated by quasi-elastic neutron scattering (QENS) and dielectric measurements. Two kinds of adsorbed amounts of liquids were studied: surface-adsorbed and capillary-condensed. The QENS measurem…
This letter presents a side-hole fiber-based extrinsic Fabry–PÉrot interferometric (EFPI) sensor whose cavity was filled with sulfur hexafluoride (SF$_{6}$) forin situpower transformer partial discharge detection. The Fabry–PÉrot cavity was formed by a polished thin diaphragm and a cleaved side-hole fiber that were th…
We report two types of site-selective metal deposition methods based on colloidal crystal templating. We discuss in particular the controllability of the morphology and crystallinity of Au nanodots depending of the choice of method.
The photophysical properties of four axially substituted indium phthalocyanines, namely, 2,(3)-tetra- tert-butyl-phthalocyaninato indium chloride ( 1), 2,(3)-tetra-[(3,5-di- tert-butyl)-phenyloxy]-phthalocyaninato indium bromide ( 2), 2,(3)-tetra-[(3,5-di- tert-butyl)-phenyloxy]-phthalocyaninato indium iodide ( 3), an…
We report first-principles calculations of the electronic structure, phonon dispersions, and electron-phonon coupling of LaNiPO. These calculations show that this material can be explained as a conventional electron-phonon superconductor in contrast to the FeAs based high-temperature superconductors.
Abstract Indium tin oxide (ITO) has attracted intense interest as the most important transparent conducting oxide (TCO) that sees wide use in many opto‐electronic and photo‐chemical devices. The goal of this study is to explore the possibility of depositing ITO thin films using a bioinspired aqueous deposition route a…
The Cu(II) doped MgO system is known to display features indicating behavior intermediate between static and dynamic Jahn−Teller effects at low temperature. The system is interesting as there is a low barrier between equivalent Jahn−Teller distortions in the cubic host lattice. In order to study the geometry of the Cu…
Abstract Acrylonitrile–butadiene–styrene (ABS)–clay composite and intercalated nanocomposites were prepared by melt processing, using Na‐montmorillonite (MMT), several chemically different organically modified MMT (OMMT) and Na‐laponite clays. The polymer–clay hybrids were characterized by WAXD, TEM, DSC, TGA, tensile…
In this letter, we report on the digestion of starch, when present as a composite with Au nanoparticles (NPs), by alpha-amylase. It has been observed that the rate of digestion of free starch and that in the composite were identical. Also, the well-established iodine test could be carried out to investigate the kineti…
Abstract We have investigated the electrical and light‐emitting characteristics of (001)‐oriented homoepitaxial diamond p–i–n junction diodes with the boron‐doped p‐type, non‐doped intrinsic, and phosphorus‐doped n‐type layers formed by applying an optimized homoepitaxial growth technique based on microwave plasma‐enh…
By using the spray-layer-by-layer (Spray-LbL) technique, the number of metal counterions trapped within LbL coatings is significantly increased by kinetically freezing the film short of equilibrium, potentially limiting interchain penetration and forcing chains to remain extrinsically compensated to a much greater deg…
The late Olivier Kahn formulated a research objective for molecular magnetism: ‘The normal trend for the molecular state is the pairing of electrons […] with a cancellation of the electron spins. The design of a molecule-based magnet requires that this trend be successfully opposed.’ One strategy for enforcing ferroma…
Abstract Blown extruded films of low‐density polyethylene (LDPE) have been subjected to climatic ageing in a sub‐Saharan facility at Laghouat (Algeria) with direct exposure to sun. Samples were characterized by complementary techniques after prescribed amounts of time up to 8 months. It was shown by tensile testing th…
Bond critical point (bcp) and local energy density properties for the electron density (ED) distributions, calculated with first-principle quantum mechanical methods for divalent transition metal Mn-, Co-, and Fe-containing silicates and oxides are compared with experimental model ED properties for tephroite, Mn 2SiO…
Iron-sulfur proteins play indispensable roles in a broad range of biochemical processes. The biogenesis of iron-sulfur proteins is a complex process that has become a subject of extensive research. The final step of iron-sulfur protein assembly involves transfer of an iron-sulfur cluster from a cluster-donor to a clus…

Abstract The use of diamond as a material for high power electronics requires high‐purity monocrystalline thick diamond films. Hence it is extremely important to have perfect control of the morphology during the entire growth process, so that the useable surface be maximized and residual stresses (which may cause crac…
The new bis-iminopyrrolyl five-coordinate Co(II) complexes [Co(kappa (2) N, N'-NC 4H 3C(R)N-2,6- (i)Pr 2C 6H 3) 2(PMe 3)] (R = H 3a; Me 3b) were synthesized in high yields (ca. 80-90%), using THF and diethyl ether as solvents, respectively, by (a) treatment of CoCl 2(PMe 3) 2 with the corresponding iminopyrrolyl Na sa…
