Abstract The hybridization of lipid membranes with inorganic silica‐based framework results in mechanically stable biomembrane mimics. This account describes three types of silica‐based biomimetic membranes. As the first example, a Langmuir monolayer of dialkylalkoxysilane was polymerized and immobilized onto a porous…

Abstract The synthetic chemistry of tetrathiafulvalene (TTF)-type electron donors has been markedly promoted by introducing two key reactions, the one-pot preparation of 1,3-dichalcogenole-2-chalcogenones from terminal alkynes and the formation of heterocyclic rings via transalkylation on a chalcogen atom. In combinat…

Polymethyl methacrylate (PMMA) microspheres with clear surface and diameter close to 1μm were synthesized by newly soap-free emulsion polymerization. The results showed that the presence of ethanol and NaCl made the increase of diameter and distribution, while the presence of toluene could avoid the problem of the inc…

Aligned carbon nanotubes were prepared by plasma-enhanced hot filament chemical vapor deposition using CH4, H2, and NH3 as reaction gases. It was investigated how different negative bias affects the growth of aligned carbon nanotubes. The results indicate that the average diameter of the aligned carbon nanotubes is re…

In modern microelectronics, where extreme miniaturization has led to feature sizes in the sub-micron and nanoscale range, Fourier diffusion has been found to be inadequate for the prediction of heat conduction. Over the past decade, the phonon Boltzmann transport equation (BTE) in the relaxation time approximation has…

A theory is presented for the application of Hill's matrix method to the calculation of the reflection and transmission spectra of multitone holographic interference filters in which the permittivity is modulated by a sum of repeating functions of arbitrary period. Such filters are important because they may have two…

A model for the combustion of methane-air mixtures in the presence of a catalyst in a packed-bed reactor has been developed. The one-dimensional model accounts for both gas-phase (homogeneous) and catalytic surface (heterogeneous) reactions. These reactions are modeled as single-step reactions of the Arrhenius type. H…

The use of polymer microspheres for producing fine-cellular foams is a new development in rotational molding. In previous studies, some reduction in mechanical properties has been found due to the immiscibility between the polymer shell and the matrix polymer. Coupling agents can act as a molecular bridge at this inte…
