Erythromycin is a commonly used broad-spectrum antibiotic, but resistance to this antibiotic makes its use less effective. Considerable efforts, beside finding alternatives, are needed enhance antimicrobial effect and stability against bacteria. Tetrahedral framework nucleic acids (tFNAs), novel delivery vehicle with three-dimensional nanostructure, have been studied as carrying platform of ant...

The possibility of applying membrane distillation to support the fermentation process was investigated. The capillary polypropylene membranes were assembled in the membrane modules. The studies were carried out using the standard solutions containing the compounds frequently occurring in the broths such as ethanol, citric, acetic and lactic acids, glycerol and 1,3-propanediol. The performance o...

A comparative study of immature and mature bone marrow-derived dendritic cells (BMDCs) was first performed through an atomic force microscope (AFM) to clarify differences of their nanostructure and adhesion force. AFM images revealed that the immature BMDCs treated by granulocyte macrophage-colony stimulating factor plus IL-4 mainly appeared round with smooth surface, whereas the mature BMDCs i...

High‐precision separation with increased water permeability is critical for efficient membrane‐based treatment processes. To achieve high selectivity toward different targeted species while allowing rapid transportation, the structure of membrane polyamide selective layer requires delicate regulation. Herein, an effective approach to systematically expand pore size layers by incorporating ammon...

In this paper, we perform two-dimensional simulations of cross-flow forward osmosis (FO) membrane modules in the presence of draw and feed channel spacers. For this purpose, the equations corresponding to the conservation of mass, momentum, and convection-diffusion for the mass fraction of solute are solved using a commercial finite volume flow solver. We consider six configurations of channel ...

Blend reverse osmosis membranes were fabricated using polyvinyl chloride (PVC) with cellulose acetate (CA) as polymer blends. Tetrahydrofuran (THF) and N-Methyl-2-pyrrolidone (NMP) were used as solvents. The membrane polymer solution was cast on a coated woven fabric support material. The prepared membranes have been characterized by SEM and mechanical properties. SEM r...

Considerable attention has been focused on solid oxide fuel cells (SOFCs) due to their potential for providing clean and reliable electric power. However, the high operating temperatures of current SOFCs limit their adoption in mobile applications. To lower the SOFC operating temperature, we fabricated a corrugated thin-film electrolyte membrane by nanosphere lithography and atomic layer deposi...

A neural network maps arbitrary nanostructure patterns to their wave band structures and finds geometries that support desired propagation behavior, a key advance in tailoring transport nanodevices.
