Characterization of Pullulan/Chitosan Oligosaccharide/Montmorillonite Nanofibers Prepared by Electrospinning Technique.

Pullulan/Chitosan oligosaccharide (COS)/Montmorillonite (MMT) hybrid nanofibers were electrospun from their aqueous solution using different Pullulan/COS mass ratios and variable amounts of MMT. The effects of Pullulan/COS mass ratios and MMT contents on the morphologies and properties of PulluIan/COS/MMT hybrid nanofibers were investigated. The obtained nanofibers were characterized with field emission-scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), thermo gravimetric analysis (TGA), and tensile strength measurement.

Optimum Conditions for the Fabrication of Zein/Ag Composite Nanoparticles from Ethanol/H₂O Co-Solvents Using Electrospinning.

The optimum conditions for the fabrication of zein/Ag composite nanoparticles from ethanol/H₂O cosolvents using electrospinning and the properties of the composite were investigated. The zein/Ag nanoparticles were characterized using field-emission scanning electron microscopy, transmission electron microscopy (TEM), X-ray diffraction (XRD), and thermogravimetric analysis. The antibacterial activity of the zein/Ag composite nanoparticles was also investigated.

Novel preparation and characterization of human hair-based nanofibers using electrospinning process.

Human hair-based biocomposite nanofibers (NFs) have been fabricated by an electrospinning technique. Aqueous keratin extracted from human hair was successfully blended with poly(vinyl alcohol) (PVA). The focus here is on transforming into keratin/PVA nanofibrous membranes and insoluble property of electrospun NFs.

Characterization of carbon nanotube-cdse hybrid nanomaterials.

MWNT-CdSe hybrid nanomaterials were prepared with carboxylic acid-treated CdSe nanoparticles and amino-functionalized MWNTs. The hybridization of MWNT-CdSe nanomaterials was performed by the formation of covalent bond between MWNT and CdSe. Their covalent bond lengths were varied with changing the linking spacers.

Characterization of attractive interaction-driven carbon nanotube composites with Cd-based nanoparticles.

Multiwalled carbon nanotube (MWNT) composites with cadmium telluride (CdTe) or cadmium selenide (CdSe) nanoparticles were prepared via electrostatic interaction. The MWNTs were modified with carboxylic acid groups. Both the CdTe and CdSe nanoparticles were stabilized with 2-(dimethylamino) ethanethiol hydrochloride to develop positive charges on their surfaces in water.
