A superfine Li0.33La0.557TiO₃ (LLTO, 69.4 nm) was successfully synthesized by a facile solvent-thermal method to enhance the electrochemical properties of the lithium-ion battery separator. Co-axial nanofiber of cellulose and Poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP) was prepared by a co-axial electrospinning technique, in which the shell material was PVDF-HFP and the core was...

INTRODUCTION: Restoration of acquired, congenital, or age-related soft tissue defects using autologous or implantable materials can cause donor site morbidity, infection, device failure, and fibrosis. Injectable fillers are limited by variable resorption and fat grafting causes necrosis in large volumes. An alternative approach using the body’s regenerative capacity and an injectable synthetic ...

The SrTiO3 modified rutile TiO2 composite nanofibers were synthesized by a simple electrospinning technique. The result of XRD, SEM and TEM indicate that the SrTiO3/TiO2 heterojuction has been prepared successfully. Compared with the TiO2 and SrTiO3, the photocatalytic activity of the SrTiO3/TiO2 (rutile) for the degradation of methyl orange exhibits an obvious enhancement under UV illumination...

Superhydrophobic poly(vinylidene fluoride) PVDF-SiO2 composite membranes with different % of SiO2 contents were prepared by electrospinning. The surface morphologies of the membranes are characterized by using scanning electron microscopy. The nanofibers in the membranes were stacked in layers to produce fully interconnected pores that resulted in high porosity. The incorporation of SiO2 into t...

In this article, we describe a microfluidic approach to fabricate hollow and core/sheath nanofibers by electrospinning. Key benefits in using microfluidic devices for nanofiber synthesis include rapid prototyping, ease of fabrication, and the ability to spin multiple fibers in parallel through arrays of individual microchannels. Hollow poly (vinylpyrrolidone) (PVP) + titania (TiO2) composite an...

We previously reported the preparation of a self-assembled chitin nanofiber (CNF) film via regeneration from an ion gel with an ionic liquid, followed by sonication and filtration. Based on the finding that CNFs were redispersed in a mixture of the film with ammonia aqueous solution (aq.), in this study, CNF-natural rubber (NR) composite sheets were fabricated by mixing redispersed CNF with NR ...

Vitaliy Datsyuk, a Svitlana Trotsenko and Stephanie Reich a Freie Universität Berlin, FB Physik, Institut für Experimental Physik, Arnimallee 14, 14195 Berlin, Germany Highly thermally conductive carbon nanotube/polybenzimidazole polymer nanofiber composites were produced by core-shell electrospinning. The in-plane thermal conductivity increased by factor of 50 for 1.94 %wt. carbon nanotubes in...

N,N-dichloropolystyrene sulfonamide as a decontaminant was synthesized in 5 steps from styrene monomer. Styrene was first polymerized. Then, sulfonation reaction was performed by H2SO4 (c) followed by chlorination with POCl3 obtain chlorosulfonated polystyrene. Amidification reaction was then applied to get sulfonamide resin. Sulfonamide resin was treat...

Abstract Probiotic products require high number of viable and active microorganisms during storage. In this work, the survival human vaginal Lactobacillus gasseri CRL1320 rhamnosus CRL1332 after nanofiber-immobilization by electrospinning with polyvinyl-alcohol, storage was evaluated. The optimization bacterial immobilization conditions using bioprotectors (skim milk-lactose glycerol) oxygen-ex...

In this paper, we have studied on the numerical model for the complex permittivity of carbon nanocomposites in microwave frequency band based on the percolation theory. The model was built up for complex permittivity of E-glass fabric/epoxy composite laminates containing carbon black (CB), carbon nanofiber (CNF) at the frequency band of 0.5 GHz ~ 18.0 GHz. It is composed of the numerical equati...
