Throughout development, surface moisture significantly increased skin permeance. The effect was largest during early development and decreased towards maturity. Recovery time courses revealed that following moisture treatment of young fruit for 12 days, skin permeance continued to increase until about 14 days after terminating the moisture treatment.

For non russeted genotypes, the value of P ES was significantly related to the permeance determined on the same intact fruit P fruit . Close relationships were also found between the F fruit calculated from P ES determined on the same fruit and the measured F fruit .

Moisture exposure increased cuticular microcracking and permeance. During moisture exposure, permeance increased over the first 4 d, remained constant up to approximately 8 d, then decreased for longer exposure times.

The contribution of lenticels differed among cultivars averaging in the cheek region 19 in Wellant and 8 in Pinova apple. The permeance of the periderm of a lenticel exceeded that of a russeted fruit skin 5.8 fold in Wellant and 5.2 fold in Pinova . Skin permeance was positively and significantly related to both lenticel density and cumulative lenticel area within a region or between regions in Wellant .

Inducing ripening using ethylene increased autocatalytic ethylene production, induced a change in skin color from green to yellow, but had no effect on the skin water vapor permeance. The permeance was highest at the calyx end of the fruit but there was no significant gradient of permeance along the remaining axis or among the three faces of the fruit.

The performance of the composite membranes in terms of solvent permeance and solute rejection was investigated by studying the rejection of a broad range of different molecular weight dyes in dimethylformamide DMF solution. The membranes showed an average DMF permeance of 1.2 L m 2 h 1 bar 1 with a molecular weight cut off of around 500 g mol 1 . The membrane was stable in DMF over 30 days with no significant change in perfor...

Nunes, Klaus Viktor Peinemann Abstract Synthetic membranes with a high selectivity for demanding molecular separations and high permeance have a large potential for the reduction of energy consumption in separation processes. Herein, for the first time, the fabrication of an ultrathin layered macrocycle membrane for molecular separation in organic solvent nanofiltration using per 6 amino cyclodextrin as a monomer for membrane manufact...

A ZIF 7 nano filler that was synthesized in our lab was embedded into a designed polymer matrix at various loadings and the performance of the mixed matrix membranes was evaluated in terms of gas permeance and selectivity. Hybrid membranes with various loadings 20, 30 and 40 wt were developed and tested at room temperature by a custom made time lag equipment and a jump in selectivity was observed when compared with the pristine polymer.
