Microporous materials, having pores and channels on the same size scale as small to medium molecules, have found many important applications in current technologies, including catalysis, gas separation and drug storage and delivery. Many of their properties and functions are related to their detailed local structure, such as the type and distribution of active sites within the pores, and the sp...

BACKGROUND Among the various strategies to avoid exaggerated foreign body reaction in the treatment of hernias is the limitation of the amount of polypropylene or the use of absorbable material. AIM To evaluate the healing of defects in the abdominal wall of rats, comparing microporous polypropylene, macroporous polypropylene and polypropylene/polyglecaprone at the 30º, 60º and 120º postopera...

Cell response on microporous membranes is important since the membranes are often used for the applications of tissue engineering. We previously developed the 3D stacked-up culture of hepatic progenitor cells, which are small hepatocytes (SHs), where the cells were cultured on microporous membranes for reconstructing layered tissues in vitro. Since membranes with randomly distributed micropores...

A series of novel oxide catalysts, which contain three-dimensionally ordered macroporous (3DOM) and microporous structure, were firstly designed and successfully synthesized by simple method. In the as-prepared catalysts, 3DOM SiO2 is used as support and microporous K-OMS-2 oxide nanoparticles are supported on the wall of SiO2. 3DOM K-OMS-2/SiO2 oxide catalysts were firstly used in soot particl...

Microporous hydroxy-sodalite zeolite membranes with different morphologies were synthesized via secondary growth technique with vacuum seeding on tubular α-Al2O3 supports at two different synthesis conditions (i.e. two different routes). Microstructures of the synthesized membranes were characterized by X-ray diffraction (XRD), Scanning electron microscope (SEM) and si...

Plantlets grown in conventional tissue culture systems usually encounter physiological and anatomical abnormalities including inability to photosynthesize, low chlorophyll content, open stomata, lack of a cuticle layer in the leaf, abnormal xylem parenchyma etc. Photoautotrophic and photomixotrophic systems could diminish these problems. The purpose of this study was to increase the chlorophyll...

Abstract A three-dimensional multicomponent multiphase lattice Boltzmann model (LBM) is established to the coupled two-phase and reactive transport phenomena in cathode electrode of proton exchange membrane fuel cells. The gas diffusion layer (GDL) microporous (MPL) are stochastically reconstructed with inside dynamic distribution oxygen liquid water resolved, catalyst simplified as a superthin...

Organic solvent nanofiltration (OSN) is an emerging membrane separation technology, which urgently requires robust, easily processed, OSN membranes possessing high permeance and small solutes-selectivity to facilitate enhanced industrial uptake. Herein, we describe the use of two 2,2′-biphenol (BIPOL) derivatives fabricate hyper-crosslinked, microporous polymer nanofilms through IP. Ultra-thin,...
