Thin Film Composite – Polyamide (TFC-PA) are commonly used reverse osmosis (RO) membranes in water desalination and waste water applications. Their poor chlorine tolerance and fouling characteristics constrain the life and performance leading to stringent chemical pretreatment requirements. In this context, development of fouling resistant and chlorine tolerant RO membranes would be relevant to...

Resveratrol has proven potential natural antioxidant, non-flavanoid polyphenolic compound, but it limitations such as low water solubility, which substantially restricts oral bioavailability. To enhance bioavailability and antioxidant of resveratrol by fabricating the encapsulated eudragit® E100 based polymeric nano-delivery system. Resveratrol-encapsulated nanoparticles (Resveratrol-polymeric ...

pH-sensitive micelles with hydrophilic core and hydrophilic corona were fabricated by self-assembling of triblock copolymer of poly(methylacrylic acid)-poly(ethylene glycol)-poly(methylacrylic acid) at lower solution pH. Transmission electron microscopy and laser light scattering studies showed micelles were in nano-scale with narrow size distribution. Solution pH value and the micelles concent...

d-Glucosamine (DG) was conjugated to a core-cross linked polymeric micelle (CCPM) system equipped with both a near-infrared fluorophore (NIRF) and a gamma emitter (111In). The resultant nano-scale tumor-targeting imaging tracer, 111In-DG-NIRF-CCPM, selectively accumulated in a human epithelial carcinoma A-431 xenograft model in mice. At 24 hrs post injection, the tumor uptake was 2.62 ± 0.80 % ...

The investigation on the thermal stability of macro and nano molecular network has emerged, over the years, as a powerful tool for their characterization [1, 2, and3]. The structure of the main chain, the main chain bonds and the nature of the crosslink’s and the presence of any extra-network materials all affect the thermal stability of polymer composites. Thermo Gravimetric analysis (TGA) tog...

Ultrathin metal coordination Prussian blue (PB) nanoribbons with tunable width have been successfully synthesized. The morphology and microstructure of PB nanoribbons are characterized using UV-vis, FT-IR, AFM, TEM and XRD. PB nanoribbons synthesized possess an ultrathin thickness of approximately 1 nm and narrow width. The width of PB ribbons can be tuned by varying the chain length of polymer...

Nanoparticles (NPs) as a nanotechnologies unit have huge potential for improving drilling fluids. However, the role of NPs in this field is still its infancy and consequently has attracted much more attention last years. This review going to investigate fluids modified by nanoparticles. Moreover, effects various nanoparticles include polymeric, ceramic, metal carbon-based on fluid technical eco...

Abstract Environmental space threats are becoming more critical as they affect the optical, thermal, and electrical properties of reinforced fiber polymeric-based materials in spacecraft. Three different Nano-particles Alumina (Al 2 ,O 3 ), Multiwall Carbon Nanotubes (MWCNT), Reduced Graphene Oxide (RGO) were added to epoxy matrix then by bidirectional carbon plain form fiber/epoxy hand lay-up ...

PURPOSE Nanogel, a nanoparticle prepared from a cross-linked hydrophilic polymer network, has many biomedical applications. A radiation technique has recently been introduced as one of the appropriate methods for the preparation of polymeric nanogels due to its additive-free initiation and easy control procedure. METHODS We have investigated the formation of nano-sized polymeric gels, based o...
