Keto-fluorothiopyranosyl nucleosides: a convenient synthesis of 2-and 4-keto-3-fluoro-5-thioxylopyranosyl thymine analogs
(2011)A novel series of fluorinated keto-beta-D-5-thioxylopyranonucleosides bearing thymine as the heterocyclic base have been designed and synthesized. Deprotection of 3-deoxy-3-fluoro-5-S-acetyl-5-thio-D-xylofuranose (1) and ... -
Mn-feroxyhyte: The role of synthesis conditions on As(III) and As(V) removal capacity
(2014)This study evaluates the critical parameters of synthesizing nanocrystalline tetravalent Mn-feroxyhyte, a single-phase arsenic adsorbent equally efficient against As(III) and As(V). The production of such Fe/Mn oxy-hydroxides ... -
A model-based parametric analysis of a direct ethanol polymer electrolyte membrane fuel cell performance
(2009)In the present work, a model-based parametric analysis of the performance of a direct ethanol polymer electrolyte membrane fuel cell (DE-PEMFC) is conducted with the purpose to investigate the effect of several parameters ... -
Occurrence of Cr(VI) in drinking water of Greece and relation to the geological background
(2015)This study provides a survey on potential Cr(VI) exposure attributed to drinking water in Greece. For this reason, a wide sampling and chemical analysis of tap waters from around 600 sites, supplied by groundwater resources, ... -
Performance of a SOFC fed by ethanol reforming products
(2002)Performance of a Pt based anode solid oxide fuel cell (SOFC) fed with a gas mixture containing H-2, CO and CH4 (molar ratio 1: 1: 1) produced by external ethanol decomposition was studied, Experiments were performed at ... -
Physicochemical stability of parenteral nutrition supplied as all-in-one for neonates
(2008)Background: Common clinical practice for the provision of parenteral nutrition of neonates is to administer the nutrients in separate solutions. The aim of this study was to introduce and examine an alternative way of ... -
Pt-based anode catalysts for direct ethanol fuel cells
(2004)In the present work, several carbon supported PtSn and PtSnRu catalysts were prepared with different atomic ratios and tested in direct ethanol fuel cells (DEFC) operated at lower temperature (T=90 degreesC). XRD and TEM ... -
PtM/C (M = Sn, Ru, Pd, W) based anode direct ethanol-PEMFCs: Structural characteristics and cell performance
(2007)In the present work, the role of the structural characteristics of Pt-based catalysts on the single direct ethanol proton exchange membrane fuel cell (PEMFC) performance is examined. Several PtM/C (M = Sn, Ru, Pd, W) ... -
Resveratrol enhances exercise training responses in rats selectively bred for high running performance
(2013)High Capacity Runner (HCR) rats have been developed by divergent artificial selection for treadmill endurance running capacity to explore an aerobic biology-disease connection. The beneficial effects of resveratrol ... -
A temperature-programmed-reduction study on La1-xSrxCrO3 and surface-ruthenium-modified Lal-xSrxCrO3
(2007)A series of La1-xSrxCrO3 (0 <= x <= 0.3) composite oxides were prepared by a modified citric method. These perovskite oxides were further modified with Ru through impregnation. X-ray diffraction, X-ray photoelectron ... -
Tetravalent Manganese Feroxyhyte: A Novel Nanoadsorbent Equally Selective for As(III) and As(V) Removal from Drinking Water
(2013)The development of a single-phase Fe/Mn oxy-hydroxide (delta-Fe0.76Mn0.24OOH), highly efficient at adsorbing both As(III) and As(V), is reported. Its synthesis involves the coprecipitation of FeSO4 and KMnO4 in a kilogram-scale ... -
Thermogravimetric analysis of soot emitted by a modern diesel engine run on catalyst-doped fuel
(2003)Understanding the mechanisms that affect catalytic activity in porous ceramic diesel particulate filters (DPF) at the temperature range 200 to 400degreesC is important for the successful modeling of the initiation and ... -
Three-way catalytic converter modeling as a modern engineering design tool
(2004)The competition to deliver ultra low emitting vehicles at a reasonable cost is driving the automotive industry to invest significant manpower and test lab resources in the design optimization of increasingly complex exhaust ...
