BACKGROUND Construction of microbial biocatalysts for the production of biorenewables at economically viable yields and titers is frequently hampered by product toxicity. Membrane damage is often deemed as the principal mechanism of this toxicity, particularly in regards to decreased membrane integrity. Previous studies have attempted to engineer the membrane with the goal of increasing membran...

Engineering low-frequency phonon transport in nanostructures with the resonant mechanism has become an important research direction. On basis of non-equilibrium molecular dynamics simulations, thermal pristine and Si-membranes bounded {100}, {110} {111} facets is investigated. It found that creation surfaces can introduce anisotropic due to lattice symmetry breaking. Besides, ballistic membrane...

introduction: endothelial cells are subjected to mechanical forces caused by pulsatile flow and pressure leading to hemodynamic shear stress and circumferential stress on endothelial layer. the study aimed at a quantitative evaluation of endothelial cell morphology by application of cyclic loading. endothelial cells respond to applied loads with adaptation and remodeling. such mechanisms are ma...

Abstract Detection and isolation of target cells from heterogeneous mixtures are highly demanded in medicine, tissue engineering, cell biology. Likewise requested measuring techniques for significant biomarkers indicating changes cellular phenotype like size distribution deformability blood cells. A forward‐looking label‐free enrichment concept based on a membrane system made out stimulus‐respo...

the energy requirement of vacuum membrane distillation (vmd) with or without recirculation was modelled using both experimental results and theoretical data. the trends are generally consistent between the theoretical and experimental data. thermal energy contributes the most to the total energy required for the vmd process. to lower the thermal energy cost, waste heat resource and heat recover...

Membrane reactors are currently under extensive research and development. Hardly any concept however is realized yet in practice. Frequently, forgotten as membrane reactors are electro-catalyic membrane reactors where electrodes perform chemical conversations and membranes separate the locations of conversion. In this chapter we extensively describe a technology where the membrane itself is cat...

Skin engineering provides a new strategy for treating a wide variety of skin defects. In particular, electrospun nanofibrous membranes have been used as carriers for epidermis engineering. The aim of this study was to investigate the feasibility of a modified gelatin and polycaprolactone (GT/PCL) electrospun membrane for epidermis engineering. The biocompatibility of the membranes was evaluated...

the overall goal of this study was to identify the appropriate biomaterials able to facilitate the regeneration in rat's injured adult spinal cord. acute damage to axons is manifested as a breach in their membranes, ionexchange distortion across the compromised region, local depolarization and even conduction block. it would be of particular importance to interrupt the progress of events h...
