Using surface analysis, simultaneous effects of temperature (260-380ºC) and ethanol concentration (0-1%) on dimethyl ether (DME) selectivity, yields of hydrocarbon and DME, and methanol conversion were investigated in methanol dehydration reaction over γ-Al2O3 catalyst. Methanol conversion and yield of hydrocarbon/DME were found to be significantly affected by temperature and the temperature-et...

Nanoparticle (NP) sintering is a major cause of the deactivation supported catalysts. Raspberry-colloid-templated (RCT) catalysts are an emerging class materials that show unprecedented level sinter-resistance and exhibit high catalytic activity. Here comprehensive study origin NP stability accessibility in RCT using theoretical modeling, 3D electron microscopy, epitaxial overgrowth reported. T...

Recombinant mouse interleukin 10 (IL-10) was exceedingly potent at suppressing the ability of mouse peritoneal macrophages (mOb) to release tumor necrosis factor a (TNF-o~). The ICs0 of IL-10 for the suppression of TNF-ol release induced by 0.5 #g/ml lipopolysaccharide was 0.04 _+ 0.03 U/ml, with as little as 1 U/ml suppressing TNF-ot production by a factor of 21.4 + 2.5. At 10 U/ml, II.-10 mar...

the effects of confinement in carbon nanotubes on fischer-tropsch (ft) activity, selectivity and lifetime of carbon nanotubes (cnts) supported iron catalysts are reported. a method was developed to control the position of the catalytic sites on either inner or outer surface of carbon nanotubes. tem analyses revealed that more than 80% of iron oxide particles can be controlled to be positioned a...

To deeply understand the factors that affect the conversion of lignocellulosic biomass to fermentable sugars, experimental results should be bridged with process simulations. The objective of this paper is to review published research on modeling of the pretreatment process using leading technologies such as dilute acid, alkaline, and steam explosion pretreatment, as well as the enzymatic hydro...

Recombinant mouse interleukin 10 (IL-10) was exceedingly potent at suppressing the ability of mouse peritoneal macrophages (m phi) to release tumor necrosis factor alpha (TNF-alpha). The IC50 of IL-10 for the suppression of TNF-alpha release induced by 0.5 microgram/ml lipopolysaccharide was 0.04 +/- 0.03 U/ml, with as little as 1 U/ml suppressing TNF-alpha production by a factor of 21.4 +/- 2....
