Manganese removal from water by magnesium enriched kaolinite-bentonite ceramics
(Taylor&Francis, 2012)
Manganese is frequently present at elevated concentrations in both surface and groundwater. In addition, manganese is a health hazard, highly soluble over a wide pH range and difficult to remove from the contaminated waters. ...
Aromaticity and conformational deformability of some environmental pollutants - methylated anthracenes
(Parlar Scientific Publications, 2014)
There is little information on methylated anthracenes which are constituents of diesel fuel. In this paper, a theoretical investigation of some molecular properties of methyl-anthracenes (MAs), 1-MA and 2-MA, and all ...
The effect of the structure of mixed tetraoxanes on their chromatographic behavior on different adsorbents
(Research Inst Medicinal Plants, Budakalasz, 2004)
The retention behavior of 29 biologically active compounds, mixed 1,2,4,5-tetraoxanes, has been investigated by thin-layer chromatography on unmodified silica, CN-silica, and RP-18-silica. The binary mobile phases ethyl ...
Hydrogenation of soybean oil over Ag-Ni/diatomite catalysts. Effect of silver content on the cis/trans isomerization selectivity
(Materials Science Forum, 2006)
Silver promoted nickel catalysts supported on diatomite were prepared by precipitation method. Characterization of the catalysts prepared with different silver contents (0.1-4.0 wt%) included AAS, XRD, Hg porosimetry, BET ...
Enhancement of the electrochemical reduction of oxygen at platinum by nickel underpotential deposition
(Springer Nature, 2006)
Polycrystalline Pt electrode was modified by underpotential deposition (upd) of nickel. The modification was performed by potential cycling in phosphate buffer pH7. 0 containing NiSO 4 , in which hydrogen and nickel upd ...
The effects of centrally applied ghrelin on appetite and metabolic parameters during aging
(Inst Materials Physics, 2014)
The main purpose of this study was to evaluate specifically, ingestive behavior and bloodborne indicators of metabolic status, after daily intracerebroventricular (ICV) ghrelin injections, in rats of different ages. Four ...
Yb3+ doped dyphillosilicates prepared by thermally induced phase transformation of zeolites
(Maik Nauka/Interperiodica/Springer, New York, 2007)
Yb3+-doped Ba and Sr diphyllosilicates (hexacelsians) have been synthesized using the Na form of LTA zeolite by ion-exchange procedure and thermal treatment. The crystal structures of both doped samples are refined and ...
Synthesis and performance of polymer based magnetic composite sensing element
(Inst Materials Physics, 2015)
The commercial multi-mode optical fiber was coated with magnetic composite material prepared using Nd-Fe-B permanent magnet powder dispersed in poly (ethylene-co-vinyl acetate)-EVA. Characterization of microstructure, ...
Allozyme polymorphism of Mdh and alpha-Gpdh in Ixodes ricinus populations: comparison of borreliae-infected and uninfected ticks
(Springer, Dordrecht, 2006)
Ixodes ricinus Linnaeus (Acari: Ixodidae) ticks are vectors of numerous infectious diseases in humans and animals. The allozyme variability of MDH and alpha-Gpdh was detected by native polyacrylamide gel electrophoresis ...
