We report on the observation of the square grid superlattice pattern in dielectric barrier discharge system. Instantaneous images taken by an intensified charge-coupled device show that the pattern is an interleaving of four transient sublattices including three square sublattices and a cross-shaped halo sublattice. C…
Large-sized (ca. 40 nm) mesoporous Er2O3 thin films are synthesized by using a triblock copolymer poly(styrene-b-2-vinyl pyridine-b-ethylene oxide) (PS-b-P2VP-b-PEO) as a pore directing agent. Each block makes different contributions and the molar ratio of PVP/Er(3+) is crucial to guide the resultant mesoporous struct…
The magnetic properties of bis(8-hydroxyquinoline)copper ([Formula: see text]) were investigated by experiments and first-principles density functional theory (DFT) calculations. The as-prepared [Formula: see text] film shows paramagnetic behavior. After annealing in air, room temperature ferromagnetic (FM) properties…
In this paper, we demonstrate that the hybridization bandgap (HBG) can be tuned conveniently by deep subwavelength meta-molecules with in-unit interaction. Spontaneous-emission-cancellation-like (SEC-like) effect is realized in a meta-molecule by introducing the destructive interference of two detuned meta-atoms. The…
An electronic detector of surface plasmon polaritons (SPP) is reported. SPPs optically excited on a metal surface using a prism coupler are detected by using a close-coupled metal-oxide-semiconductor capacitor. Semitransparent metal and graphene gates function similarly. We report the dependence of the photoresponse o…
Recently thermo-electrical nanoantennas, also known as Seebeck nanoantennas, have been proposed as an alternative for solar energy harvesting applications. In this work we present the optical and thermal analysis of metallic nanoantennas operating at infrared wavelengths, this study is performed by numerical simulatio…
Traditional EUV masks, with absorber on top of the multi-layer (ML) mirror, generally suffer from mask 3D effects: H/V shadowing, best focus shifts through pitch and pattern shifts through focus. These effects reduce the overlapping process window, complicate optical proximity correction and generate overlay errors. W…
Apres une description du contexte d'utilisation des composants magnetiques et des condensateurs en electronique de puissance, ce document fournit les bases de leur dimensionnement. Sont concernes : les inductances, les transformateurs de puissance, d'impulsion et de courant ainsi que les condensateurs de puissance.
Reaction of AgNO3 and N,N,N',N'-tetrakis((diphenylphosphino)methyl)benzene-1,4-diamine (pbaa) with sodium N-ethyldithiocarbamate (Na(Etdtc)) in CH3CN/toluene and CH3CN/DMF solvents produced two Ag4S4-based coordination complexes [Ag4(pbaa)(µ-?1S,?2S-Etdtc)4] (1) and [Ag4(pbaa)(µ-?1S,?2S-Etdtc)2(µ-?1S,?1S-Etdtc)2] (2).…
When a film is strained in two dimensions, it can relax by developing a corrugation in the third dimension. We review here the resulting morphological instability that occurs by surface diffusion, called the Asaro–Tiller–Grinfel'd instability (ATG), especially on the paradigmatic silicon/germanium system. The instabil…
Benzocaine (BZC) is a local anaesthetic commonly used in therapeutics. Based on published thermodynamic quantities of dissolution, partitioning, and sublimation of BZC, the thermodynamic quantities of solvation for this drug in some mutually saturated solvents were calculated. Organic solvents under consideration were…
Purpose – Solospun technology is one of the most important new spinning methods, which is implemented by dividing Ring spinning triangle into several small primary triangles and one final triangle by a Solospun roller. That is, there are two parts of spinning triangle in the Solospun technology, including primary tria…
The mechanism of water oxidation in coordination spheres of tetranuclear and octanuclear ruthenium(IV) clusters, which are prospective catalysts for water oxidation in artificial photosyntesis, is studied. It is shown that these clusters are formed in situ from ruthenium complexes K 4 [Ru 2 (SO 4 ) 2 (µ-SO 4 ) 2 (µ-O)…
Let $I$ be a strong co-ideal of a commutative semiring $R$ with identity. Let $\Gamma_{I} (R)$ be a graph with the set of vertices $S_{I} (R) = \{x \in R\setminus I: x + y \in I$ for some $y \in R \setminus I\}$, where two distinct vertices $x$ and $y$ are adjacent if and only if $x + y \in I$. We look at the diameter…
In this work, we report on the difference of mechanical stress in free standing and attached Porous silicon membranes. By performing Raman analysis, we demonstrate that the tensile stress accumulated during the etching process by the porous silicon layer is partially compensated by the presence of the substrate. We hi…
The dynamic fragility concept has been performed on kenaf and jute composites containing different reinforcement contents. Based on the average relaxation times, we have determined, as a function of the type of reinforcement and fiber content, the dynamic fragility concept of composites manufactured by resin transfer…
X-ray reflection near the Brewster’s angle by multilayer mirrors can be used to detect the polarization from X-ray sources. The photon emission spectra from some isolated neutron stars and AGN/blazars etc. show that their emission is peaked at low energies near 250eV, which is just below carbon K-absorption edge. The…
Liquid crystal (LC) is an amazing class of electro-optic media; its applications span from visible to infrared, millimeter wave, and terahertz regions. In the visible and short-wavelength infrared (SWIR) regions, most LCs are highly transparent. However, to extend the electro-optic application of LCs into MWIR and LWI…
Photochemical upconversion has been put forward as a candidate technology to improve the light-harvesting capabilities of thin-film photovoltaic cells, by harvesting transmitted sub-bandgap light and re-radiating the absorbed energy at a usable wavelength. Efficiencies of 10% have been observed under solar-level irrad…
Optical properties of silicon nanocrystals dispersed in SiO2 matrix were investigated in terms of photoluminescence quantum yield at room temperature. Two multilayer samples, prepared from substoichiometric silicon oxide layers by annealing at 1150°C were used to investigate the influence of Si concentration. Signific…
