by addition of calculated amounts of 200 g/L glucose. Serum glucose concentrations attained by this procedure were controlled by measurement with the Beckman Glucose Analyzer. The sensitivity to glucose (calculated for the range 5–10 mmol/L) in phosphate buffer (pH 7.4) was 10.2 Ϯ 3.3 nA ⅐ L ⅐ mmol Ϫ1 (mean of slopes calculated from each experiment Ϯ SE; Fig. 1A).The sensitivity to glucose afte...

In this article, we present a simple, rapid prototyped polystyrene-based microfluidic device with three-dimensional (3D) interconnected microporous walls for long term perfusion cell culture. Patterned 3D interconnected microporous structures were created by a chemical treatment together with a protective mask and the native hydrophobic nature of the microporous structures were selectively made...

_____________ _ Five Capiox II 33 (Terumo Corporation) and nine M-2000 (Shiley Incorporated) microporous polypropylene membrane lungs were evaluated for dynamic operating characteristics during apneic oxygenation. Particular emphasis was placed on carbon dioxide and oxygen transfer (VC02 and V02 respectively). The lungs were incorporated into extracorporeal venavenous bypass circuits used with ...

Hydroxyapatite (HA) can be coated on various materials surface and has the function of osteogenicity. Microporous silk scaffold has excellent biocompatibility. In this study, alternate soaking technology was used to coat HA on microporous silk scaffolds. However, the cell proliferation was found to decrease with the increasing thickness (cycles of soaking) of HA-coating. This study aims to dete...

Redox flow batteries (RFBs) are promising choices for stationary electric energy storage. Nevertheless, commercialization is impeded by high-cost electrolyte and membrane materials. Here, we report a low-cost all-iron RFB that features inexpensive FeSO4 electrolytes, microporous along with glass fiber separator. The addition of 0.1 м 1-ethyl-3-methylimidazolium chloride (EMIC) overcomes the low...

A facile approach to fabricate novel highly microporous carbons has been developed by direct carbonization of lowly cross-linked polystyrene. The as-prepared highly microporous carbons demonstrate unusually high micropore rate (97%), high surface area (1108 m(2) g(-1)) and uniform pore size distribution, and thus exhibit excellent size-selective adsorption and electrochemical properties.

A new strut containing an imidazolium tetracarboxylic acid core has been successfully incorporated into a microporous material using paddlewheel-coordinated copper(II) ions as nodes. Sorption studies conducted on this permanently microporous material imply that it can separate carbon dioxide from methane with high selectivity.

On the basis of existing dust collector structure, this study designed a fan-shaped new structure microporous membrane filter plate (NSMMFP). The pressure distribution law NSMMFP can be obtained by measuring wall surface peak under different injection pressures. powder attachment experiment was carried out to explore influence moisture content on stripping rate (DSR), and high-speed camera used...

Du Pont has commercialized a new filter media based on flash spinning technology for Tyvek spunbonded olefin. It has'an 'asymmetric pore structure, a greater number of submicron pores, and a smaller average pore size (1). As a consequence, it has superior filtration properties and longer life, and in many instances it can compete with microporous membranes, PTFE laminates, and various melt-blow...
