With the continual increase in cooling demand for microprocessors, there has been an increased focus within the microelectronics industry on developing thermal solutions. Thermal interface materials (TIMs) play a key role in thermally connecting various components of the thermal solution. Review of the progress made i…
Abstract In this review, the progress made in the last ten years concerning the synthesis of porous carbon materials is summarized. Porous carbon materials with various pore sizes and pore structures have been synthesized using several different routes. Microporous activated carbons have been synthesized through the a…
A one-step simple synthesis of silver colloid nanoparticles with controllable sizes is presented. In this synthesis, reduction of [Ag(NH(3))(2)](+) complex cation by four saccharides was performed. Four saccharides were used: two monosaccharides (glucose and galactose) and two disaccharides (maltose and lactose). The…

L'elimination des ions phosphate de solutions aqueuses par sorption sur une hydrotalcite de synthese et sur son produit de calcination a ete etudiee. Le solide [Mg-Al-CO 3 ], prepare par coprecipitation a pH constant, a ete caracterise par diffraction des rayons X, analyse thermogravimetrique et composition chimique.…
The single-crystal non-stoichiometric magnetic shape memory alloy Ni(1-x-y)Mn(x)Ga(y) with x = 0.2817, y = 0.2136 is studied using magnetic resonance spectroscopy: ferromagnetic resonance (FMR) and conduction electron spin resonance (CESR). The temperature dependence of the integral intensity, the resonance field and…

A ${\mathrm{Nd}}^{3+}$-doped ${\mathrm{Bi}}_{4}{\mathrm{Ge}}_{3}{\mathrm{O}}_{12}$ (BGO) single crystal was grown by the modified Czochralski method. Using the $4f$-energy matrix diagonalization procedure various interaction parameters viz. Slater-Condon (${F}^{2}$, ${F}^{4}$, and ${F}^{6}$), spin-orbit $(\ensuremath{…
Abstract Synthesis, crystal structure as well as IR‐ and Raman‐spectroscopic properties of the new ternary azidoaurates(III) A [Au(N 3 ) 4 ] ( A = K, Rb, Cs) are reported. The translucent orange‐red compounds were prepared by reaction of the respective binary azides with HAuCl 4 in aqueous solutions at room temperatur…
The photoluminescence (PL) behavior of γ-Al2O3 nanopowder is studied. Two emission peaks at 343 and 378nm and a broadband ranging between 400 and 600nm are observed. The peaks are attributed to F+ center, while the broadband is attributed to impurities. It is found that irradiating the sample with intense ultraviolet…
La fluorapatite presente une bonne aptitude au frittage dans le domaine de temperature 900-1100°C. Des taux de densification de 97% ont pu etre atteints. Aux temperatures elevees, la densification est entravee surtout par le grossissement des grains. La fluorapatite est tres sensible aux traces de vapeurs d'eau se tro…
The average glass transition temperatures, Tg, of thin homopolymer films exhibit a thickness dependence, Tg(h), associated with a confinement effect and with polymer-segment-interface interactions. The Tg's of completely miscible thin film blends of tetramethyl bisphenol-A polycarbonate (TMPC) and deuterated polystyre…
The time resolved luminescence and concentration quenching behavior were examined for Sr6BP5O20:Eu2+ phosphors. The emission spectrum of the Sr6BP5O20:Eu2+ phosphor could be deconvoluted into two well defined Gaussian peaks. This implies that the Eu2+ emission emanates from two different crystallographic sites for Sr2…
We present the electrical spin injection from room-temperature ferromagnetic (Ga, Mn)N in nitride-based spin-polarized light-emitting diodes. The electroluminescence spectra from the spin LED indicate the existence of the spin polarization via optical polarization of emitted light up to room temperature. This demonstr…
Abstract Well‐shaped single crystals of the phosphide oxides CeZnPO and PrZnPO were obtained from the rare earth metals, zinc oxide, and red phosphorous in an equimolar NaCl/KCl flux in sealed quartz ampoules. The high‐temperature (β) NdZnPO type modifications were obtained at 1170 K while the low‐temperature (α) ZrCu…
