The activities of acid phosphatase and alkaline phosphatase were investigated in two varieties of ripening Carica papaya fruit; Oblong-shaped variety which is also known as ‘Agric pawpaw’ and Pear-shaped variety which is also known as ‘Local pawpaw’. Acid phosphatase activity decreased significantly (p < 0.01) throughout the ripening stages from 0.0186±0.0006 to 0.0037 ± 0.0002μmol/min/g fresh ...

Ionogel fiber mats were made by electrospinning poly(methylmethacrylate) (PMMA) and the ionic liquid (IL) bis(1-butyl-3-methyl-imidazolium) tetrachloridocuprate(II), [Bmim]2[CuCl4], from acetone. The morphology of the electrospun ionogels strongly depends on the spinning parameters. Dense and uniform fiber mats were only obtained at concentrations of 60 to 70 g L−1 of polymer and IL mass combin...
