“…The absence of significant variations of the PCL crystallinity as the starch concentration grows has also been reported in previous works on this same blend system (Avella et al, 2000). However, the reduction in the concentration of 3 D ordered PCL domains has also been reported after starch addition (Cai et al, 2014;Rosa, Guedes, Pedroso, & Calil, 2004;Rosa, Lopes, & Calil, 2005;Wu, 2003). On the other hand, Wang et al (2005) found for the 70/30 blend composition a very small increase from 2 to 3% in the PCL crystallinity after Differential Scanning Calorimetry runs when different cooling rates are chosen; the crystallization rate being higher for their blend than for pure PCL, starch is viewed as an effective nucleation agent for PCL.…”

“…It was shown previously that gelatinized starch increases water absorption. [26] When barley was combined with WPC80 or CP, the solubility of the raw products increased, but decreased significantly (p < 0.05) after extrusion. This decrease in solubility can be attributed to denaturation of the proteins which has been shown to cause loss of solubility.…”

Adding whey protein concentrate (WPC80) and cashew pulp (CP) to extruded snacks can reduce overall carbohydrate content. In this study, barley, cassava, corn meal and quinoa were blended with WPC80 (12.5 wt%) or with CP (12.5 wt%), then extruded and baked. The products' rapidly available glucose values or potential glycemic index were: quinoa (70%), barley (61%), corn (54%), and cassava (48%). Adding WPC80 with or without CP improved the glycemic potential values for barley and quinoa, but not for cassava, which increased from 61 to 77%. Adding WPC80 or CP had no effect on corn products.

We investigate the fabrication of continuous carbon fiber/poly("-caprolactone) composites for biomedical applications. Two fabrication methods: in-situ polymerization and film stacking are compared at two different thicknesses. Analysis of void content produced via the two fabrication methods showed that the in-situ polymerization specimens had considerably lower void content than the film stacked samples. Significantly higher mechanical properties were obtained for the in-situ polymerized samples, and an almost three-fold increase in properties was seen as compared to the film stacked samples. Scanning electron microscopy images of surfaces supported the findings above. Dynamic mechanical analysis revealed higher dynamic modulus for the in-situ polymerized samples which was consistent with the above results.
