reflux for 24 h. After addition of 10 ml of hexane, the catalyst was removed by filtration. The filtrate was con- centrated in vacuum and the residue was analyzed by non-overlapping 1H NMR signals, characteristic for the hydroperoxide 1 [16] (singlet at 4.95 ppm),alcohol 7 [17] (singlet at 4.60 ppm),aldehyde 8 [18] (singlet at 9.95

Liquid/gas chromatography–mass spectrometry based targeted and non-targeted techniques were used to analyse fructan oligosaccharides, lipids, fatty acid methyl esters, polar and semi-polar compounds.

Doping, the intentional introduction of impurity atoms into a host lattice, is an essential process for developing semiconductor materials and devices. Over the past three decades, researchers have.

Microbial inhibition, as part of a robust cooling water treatment program. During that time, the total residual chlorine (TRC) level in the outfall must be less than 0.2 ppm. At this feed rate and.

The results of the present study indicate that nanoscaled metal fluorides, which dissolve low fluoride concentrations in aqueous solutions, promote remineralization of enamel caries lesions to a.

polyacrylonitrile are used as scale inhibitors. Ground water is retluxed from I to 24 h with and without polymers. When only water is boiled the effect of salt precipitation is found to increase with increase in time of reflux. But when the polymers are added individually, the precipitation of salt decreases with increase in amount of polymer (200 ppm to 800 ppm) as well as with increase in refl ux time for

8-nonynoic acid 40. To a solution of 8-nonynal (3.13 g, 22.7 mmol) in DMF (30 ml) was added Oxone (15.3 g, 24.9 mmol). The resulting suspension was stirred for 15 min, then poured into water. 32%.

As discussed above, the open cell voltage of one fuel cell is ~ 0.35 V, which is not high enough to split water in an acid PEMEC solution. Therefore, multi-fuel cells are assembled together in series.
