Here we report the fabrication of hollow-core cylindrical photonic bandgap fibers with fundamental photonic bandgaps at near-infrared wavelengths, from 0.85 to 2.28 microm. In these fibers the photonic bandgaps are created by an all-solid multilayer composite meso-structure having a photonic crystal lattice period as small as 260 nm, individual layers below 75 nm and as many as 35 periods. Thes...

This study aimed to reveal the influence of draw ratio and take-up speed on pore size distribution morphology hollow fiber ultrafiltration membrane selective layer. To this end, spinnerets with ring ducts 1.8 1.3 mm were employed, whereas external diameter obtained was kept equal. Atomic force microscopy scanning electron employed Liquid–liquid displacement porosimetry used determine limiting d...

Consumers are becoming more conscious about the need to include functional and nutritional foods in their diet. This has increased demand for food extracts rich proteins peptides with physiological effects that used within pharmaceutical industries. Among these protein extracts, soy its derivatives highlighted. Isolated (ISP) presents a content of at least 90%. Wastewaters generated during prod...

Abstract Background and Aims The artificial liver treatment based on blood purification is an important commonly used for failure. Aggressive management of hyperbilirubinemia one the key steps to reduce mortality in patients with Herein, targeting bilirubin nano-sized, we synthesized a TiO2/Ti3C2 nanocomposite from Ti3C2 MXenes via hydrothermal oxidation clearance whole blood. Method Firstly, M...

In this study, polyethersulfone based nanofiltration membranes were modified by air plasma generated through dielectric barrier discharge to increase the membrane hydrophilicity aiming to improve the separation and antifouling characteristics. The effect of plasma time on the physico-chemical and separation properties of membrane was investigated. The PES nanofiltration membranes were fabricate...

Organic-inorganic composite materials have attracted great attention because of their potential to combine the features of organic materials with those of inorganic materials. Particularly organic-metal composite such as polymer-silver are promising functional materials in areas ranging from electronic and optical devices to biosensing, antimicrobial agents and catalysis. In general, there are ...

Implant devices containing insulin-secreting ?-cells hold great promise for the treatment of diabetes. Using in vitro cell culture, long-term function and viability are enhanced when cultured with extracellular matrix (ECM) proteins. Here, our goal is to engineer a favorable environment within implant devices, where ECM proteins stably immobilized on polymer scaffolds, better support ?-cell adh...
