In this research, the adsorption capacity of diatomaceous earth in removal crystal violet dye (CV) aqueous solution was evaluated. The experimental methodology began with determination texture properties by adsorption-desorption isotherms N2 a 77 K, identification functional groups Fourier transform infrared spectrophotometry (FTIR), morphology scanning electron microscopy (SEM) and, pH isoelec...

■ ■ Ostro accommodates a range of sample volumes (50-350 μL) vs. the requirement for a fixed volume using SSLE IN T RO DU C T IO N The Ostro Pass-through 96-well plate provides a novel solution for simple pass through cleanup of plasma, serum, and whole blood samples that removes protein and phospholipids with little-to-no method development. It can be quickly implemented into routine lab workf...

Yeast strains of Saccharomyces cerevisiae behave differently to additions of finely sized particles added to clear grape juice. The type of material has a bearing on the effectiveness of increasing the rate of sugar conversion. In comparsion with a control sample, stirring and then adding grape solids back to the juice are most effective in maximizing sugar conversion, followed by addition of b...
