The influence of charge-carrier concentration on the magnetic properties of the semimagnetic semiconductor [(PbTe)l-x(SnTe)x]l-y[MnTe]y (x=0.72, y=O.03) is reported. Magnetization, magnetic susceptibility, and specific heat have been measured. For carrier concentrations below p = 3 x 10 cm 3 the alloy is paramagnetic. For p ~ 3 x 1020 cm 3 an abrupt transition to a fer­ romagnetic phase is obse...

We report an experimental investigation of the nonlinear optical properties of nanoporous silicon optical waveguides measured at 1550 nm. The nonlinear properties including two-photon absorption, self-phase modulation, free-carrier absorption and free-carrier plasma dispersion are characterized and compared with similar measurements conducted on a conventional silicon-on-insulator ridge wavegui...

Differential light-biased dynamic measurements of charge carrier recombination properties in semiconductors have long been known to yield only differential rather than actual recombination properties. Therefore, the determination of injection-dependent recombination properties from such measurements was previously found to require integration over the entire injection range. Recent investigatio...

Propionic acid is a carboxylic acid produced by fermentation and widely used in chemical, pharmaceutical and food industries. It is used primarily for animal feed preservation, including hay, silage, and grains, and in human foods (mainly in baked goods and cheeses). The growing demand of this acid draws attention towards a more economical energy efficient technology. The conventional methods f...

acridine derivatives, especially 1,8-dioxo-9-aryl-decahydroacridine represent significant scaffolds in medicinal chemistry. given the biological properties of such products which are used in drug development, they need to have appropriate carrier. proteins are generally used as helpful tools in drug delivery. consequently, molecular docking between these compounds and bovine serum albumin (bsa)...

Dry powder inhalers (DPIs) are distinguished from one another by their unique device geometries, reflecting their distinct drug detachment mechanisms, which can be broadly classified into either aerodynamic or mechanical-based detachment forces. Accordingly, powder particles experience different aerodynamic and mechanical forces depending on the inhaler. However, the influence of carrier partic...

Berberine was loaded in yeast cells of Saccharomyces cerevisiaeas a novel pharmaceutical carrier to improve the treatment ofmany diseases. The yeast-encapsulated active materialsshowedhigh stability and bioavailability due to the enhanced solubility and sustained releasing. In this study, different characteristics of prepared berberine loaded yeast cells (loading capacity, release kinetic order...

The atomic-layer (AL) doping technique in epitaxy has attracted attention as a low-resistive ultrathin semiconductor film as well as a two-dimensional (2-D) carrier transport system. In this paper, we report carrier properties for B AL-doped Si films with suppressed thermal diffusion. B AL-doped Si films were formed on Si(100) by B AL formation followed by Si cap layer deposition in low-energy ...
