1. Characterization of oat bran β-glucan with special reference to efficacy study to elucidate its health claims for diabetic patients
Abstract The present study was designed to characterize oat bran for their biological attributes. The results showed that bran of Avon variety contained high TDF, SDF, β-glucan and extractability of β-glucan than bran of oat variety Sargodha-81. The extrusion process exhibited the highest extractability of β-glucan (45.37%) followed by cooking (37.28%) an

7. Mechanical Behavior of Multiwalled Carbon Nanotube Reinforced 7075 Aluminum Alloy Composites Prepared by Mechanical Milling and Hot Extrusion
In this paper, multiwalled carbon nanotubes (MWCNTs) were synthesized by spray pyrolysis to be used later as material reinforcement in the production of MWCNTs/Al7075 aluminum composites. Both, MWCNTs and MWCNTs/Al7075 composites were microstructurally and mechanically characterized. Scanning electron microscopy (SEM) analysis shows MWCNTs formed by multiple
