Abstract This study aimed to characterize the physical-chemical and biological properties of pectin (PC)/chia seed mucilage (CM) membranes. PC/CM [100/0 (control), 80/20%, 60/40%, and 40/60% w/w] membranes were prepared using the casting method. The membranes (PC/CM) were thin, yellow, lightly opaque (≈10%) and capable of blocking light UVB (between 66 at 52%). SEM analysis showed the presence of aggregates in the shape of a sphere (≈13 µm) and ovoid (≈25 µm). The proportion of 80/20 showed an increase in tensile strength (29%) and elastic modulus (19%) when compared to the control. FTIR analysis exhibited intermolecular interactions between PCPC, PC-CM, and CM-CM… More > Graphic Abstract

Abstract Patients with extracorporeal membrane oxygenation still suffer from high rates of complication that linked to the flow field within the blood pump. So it is essential to optimise the geometry of the pump. The specification of shroud design is arguably the necessary design parameter in the centrifugal pump. However, the hemodynamic performances of the different shroud designs have not been studied extensively. In this study, ten different shroud designs were made and divided into two groups as the different covering locations (A: Covering the blade leading edge, B: Covering the blade trailing edge). In every group, six shroud designs with… More >
