conclusions the high prevalence of fungaemia and mortality could be attributed to many patients on chronic immunosuppressive therapy. nonetheless, cpfa albeit expensive, does add to our armamentarium of extracorporeal treatment for severe sepsis. regional citrate anticoagulation with cpfa may overcome problems with filter clotting. objectives the main objective was to review our centers' e...

Recycling rare earth elements (REEs) used in advanced materials such as Nd magnets is important for the efficient use of REE resources when the supply of several REEs is limited. In this work, the feasibility of using salmon milt for REE recovery and separation was examined, along with the identification of the binding site of REEs in salmon milt. Results showed that (i) salmon milt has a suffi...

A novel sewage-sludge derived composite material was developed for the adsorptive removal of organic pollutants from water. In this study a batch adsorption study was carried out to examine the kinetics of antibiotics adsorption by this composite material. A pseudo-second order kinetics model fits the data extremely well, suggesting that chemical adsorption, rather than physical adsorption, is ...

Dehydration of ethanol via adsorption on 3Å molecular sieves has recently been increasing in application in industry as an alternative to the conventional separation techniques for breaking the ethanol-water azeotrope. Over the past 20 years, Pressure-Vacuum Swing Adsorption (PSA) processes have gained increasing commercial acceptance as an energy-efficient separation technique. A general purpo...

Recently we have described a normal plasma activity that modulates contact activation by inhibiting adsorption of factor XI to activating surfaces. Here we report the first identified case in which a patient has abnormal clotting tests due to an excess of a similar activity. The patient's plasma had a prolonged partial thromboplastin time and low apparent factor XI assay. His plasma prolonged t...

Abstract: Electrical sensitivity of a boron nitride nanotube (BNNT) was examined toward (C3H4) molecule by using density functional theory (DFT) calculations at the B3LYP/6-31G (d) level, and it was found that the adsorption energy (Ead) of methylacetylene (C3H4) the pristine nanotubes is a bout -1.78kcal/mol. But when nanotube have been doped with Si and Al atomes, the adsorption energy of me...

The delamination of montmorillonite in water leads to sliming in ore slurry, which is detrimental to mineral flotation and solid/water separation. In this work, the delamination of Na-montmorillonite (Na-MMT) has been restrained by sodium dodecyl sulfate (SDS) or octadecyl trimethyl ammonium chloride (1831) through the adsorption on the edge of the mineral. The experimental results have shown t...

Syringopicroside is the major constituent in Folium syringae leaves with known pharmacological activities. In this study, a simple method for preparative separation of syringopicroside from F. syringae leaves with macroporous resins was developed. Adsorption characteristics of syringopicroside on six types of macroporous resins, including ADS-8, ADS-17, D141, NKA-9, HPD450, and HPD600, have bee...

Selection of mobile phases markedly affect separation efficiency of eluted probes in gas chromatography (GC), the mobile phases have a pronounced effect on the retention times and efficiency of natural gas separation. In solid chromatography, carrier gases which are adsorbed to any extent occupy more active adsorption sites, reducing the net heat of adsorption of the eluted zone. The efficiency...

Metal-organic frameworks comprise an important class of solid-state materials and have potential for many emerging applications such as energy storage, separation, catalysis and bio-medical. Here we report the adsorption behaviour of a series of fluorocarbon derivatives on a set of microporous and hierarchical mesoporous frameworks. The microporous frameworks show a saturation uptake capacity f...
