Table 1: Photovoltaic parameters of DSC devices with
malonic acid derivatives.
The monomers, 1,3-propane diol and
malonic acid, were selected based on the presence of reactive functional groups and accessibility to materials.
This can be achieved by adjusting
malonic acid concentration in the HPLC mobile phase.
Visible light photocatalytic activities of the as-prepared Au/BiV[O.sub.4] powders were evaluated by the mineralization of oxalic acid (0.208 mM) and
malonic acid (0.139 mM) in aqueous solution at ambient temperature and pressure.
This test though not as specific as the urinary methyl
malonic acid or MMA Test but is more superior to the serum B12 assay.
The anthocyanin at peak 1 (RT: 40.9) was composed of a cyanidin base conjugated with three molecules of hexose, a molecule of sinapic acid and a molecule of
malonic acid, whereas at peak 2 (RT: 44.4), the molecule was composed of a cyanidin base linked with two molecules of hexose and a molecule of sinapic acid, and at peak 3 (RT: 45.3), the molecule was composed of a cyanidin base joined with three molecules of hexose and two moieties of sinapic acid.
Detection of the carnitine ester of
malonic acid has been mentioned previously in single cases of malonic aciduria (4, 6, 7).
But Kondo's group now discovered that it instead came with an organic acid called
malonic acid attached.
Of the evaluated dicarboxylic acids, only MMA and
malonic acid showed the neutral losses of 56 and 112 Da in the MS/MS mode; the rest of the acid diesters showed a preferred neutral loss of 74 and 130 Da, similar to SA (Fig.
Experimental evidence that such a mechanism could govern a chemical system didn't emerge until 1990, when Patrick De Kepper and his co-workers at the University of Bordeaux in France produced a stationary pattern of spots in a thin gel continuously fed a fresh solution - containing
malonic acid and chlorite and iodide ions-in a special chemical reactor (SN: 8/11/90, p.88).
He and his Bordeaux co-workers have focused their attentions on carefully controlled reactions involving chlorite, iodide and
malonic acid. Stripes and dots develop within clear or sometimes yellow regions where concentrations of iodide are low; darker, blue-gray patches form where concentrations of iodide are high.
