A variety of nano-carriers, nano-particles, nano-fibers, nano-tubes etc. have displayed greater competence to mimic nanoscale environment for the enzyme as compared to microand macro-environments provided by traditional support carriers that have been commonly employed for enzyme immobilization. The porous structured beads (silica, alginate etc.), membranes and fibers (>100 μm) have some inhere...

Nano-TiO2 (NT) and nano-SiO2 (NS) were separately added in the cement paste to investigate the rheological property of fresh mixtures and mechanical strength in hardened state. The effects of different dosages and types of nano-particles on the properties of cement paste were studied. The results indicated that the rheological behavior of the fresh cement paste coincides with the Modified Bingh...

Metallic copper nanoparticles modified glassy carbon electrode is fabricated by reduction of CuSO4 in the presence of cetyltrimethylammonium bromide (CTAB) through potentiostatic method. As-prepared nanoparticles are characterized by scanning electron microscopy and electrochemical methods. Copper oxide modified glassy carbon electrode (nano-CuO/MGCE) is prepared using consecutive potential sca...

BACKGROUND The problems related to conventional Fenton oxidation, including low pH required and production of considerable amounts of sludge have led researchers to investigate chelating agents which might improve the operating range of pH and the use of nano iron particle to reduce the excess sludge. The pyrene removal from contaminated soils by modified Fenton oxidation at neutral pH was defi...

In this study, vascular stents were fabricated from poly (lactide-ɛ-caprolactone)/collagen/nano-hydroxyapatite (PLCL/Col/nHA) by electrospinning, and the surface morphology and breaking strength were observed or measured through scanning electron microscopy and tensile tests. The anti-clotting properties of stents were evaluated for anticoagulation surfaces modified by the electrostatic layer-b...
