Urine is evaluated by electrophoretic methods both to gather information about the location and degree of damage within the nephron and to detect and quantify monoclonal free light chains (Bence Jones proteins). For many years, urine protein electrophoresis consisted of concentrating the urine (usually 50-fold) followed by manual application of the concentrated sample to a gel. Recently, semiau...

Microporous polymers, that is polymers having pores of molecular size (D<2 nm), attracted a lot of interest during the last few years. They are promising materials for gas storage or separation but could also find use in heterogeneous catalysis. Recently, the separation of the green house gas CO2 evoked large interest in the scientific community. Among other microporous materials, such as activ...

The relationship between synthetic factors and the resulting structures is critical for rational synthesis of zeolites and related microporous materials. In this paper, we develop a new feature selection method for synthetic factor analysis of (6,12)-ring-containing microporous aluminophosphates (AlPOs). The proposed method is based on a maximum weight and minimum redundancy criterion. With the...

Exhibiting a very high surface area, good electrical conductivity and density of active sites, nitrogen-doped graphenic materials are considered as promising catalysts for the oxygen reduction reaction (ORR). Seldom studied in acidic media, N-doped foams were tested here cathode polymer electrolyte membrane fuel cell (PEMFC). The prepared via solvothermal-based process, by reacting either cyclo...

Potential sources of gaseous microemboli during cardiopulmonary bypass are varied. However, it is known that membrane oxygenators generate fewer gaseous microemboli than bubble oxygenators and that bubblers cannot utilize arterial heat exchange without generating significant gaseous microemboli during rewarming. A membrane oxygenator utilizing simultaneous gas and heat exchange raises the con...

Liquid membranes usually consist of an extracting agent (carrier) in an organic solvent which separates "feed" and "stripping" phases containing aqueous solutions of the solute of interest and a stripping agent, respectively. In supported liquid membranes (SLMs) the membrane solution is immobilised into a thin solid microporous support, between the feed and stripping phases where transport is f...

The catalytic behavior of Brønsted acid sites in three acidic zeolite materials (one MWW and two MFI zeolites) containing dual meso-/microporosity was studied using ethanol dehydration and monomolecular conversion of propane and isobutane as probe reactions. The meso-/microporous MWW zeolite, MCM-36 or pillared MWW, consists of a zeolitic layer structure, with independent microporosity and meso...

In this study, a novel continuous reactor has been developed to produce high quality methyl esters (biodiesel) from palm oil. A microporous TiO2/Al2O3 membrane was packed with potassium hydroxide catalyst supported on palm shell activated carbon. The central composite design (CCD) of response surface methodology (RSM) was employed to investigate the effects of reaction temperature, catalyst amo...

PURPOSE To investigate whether topically administered hemostatic agents ankaferd blood stopper and microporous polysaccharide hemospheres can decrease epidural fibrosis after laminectomy in rats. METHODS Eighteen adult male Sprague-Dawley rats were equally and randomly divided into three groups. In the treatment groups, ankaferd blood stopper and microporous polysaccharide hemospheres topical...

A direct hydrothermal assembly process was developed to synthesize mesoporous aluminophosphates that are constructed with crystalline microporous frameworks, by the addition of organosilane surfactants into the conventional synthesis composition for crystalline microporous aluminophosphates.
