Super-porous PVDF nanofibre membranes for efficient desalination of brackish water in membrane distillation applications

Mhlanga S.D., Nthunya L.N., Khumalo N.P., Verliefde A.R., University of South Africa, ZA

Water scarcity is becoming a serious problem in Southern Africa. Recent draughts have called for exploitation of alternative sources of drinking water such as brackish and seawater. Membrane distillation is an efficient desalination process that [...]

Novel electrospun PVA/Fe-MOF nanofibres as a super adsorbing material of lead ions in aqueous solution

Shooto N.D., Dikio E.D., Sikhwivhilu L., Wankasi D., VUT, ZA

In this study electrospun PVA nanofibres were functionalized with Fe-MOFs to synthesise a novel super adsorbing material. The synthesized material was characterized by scanning electron microscope (SEM), Fourier transform infrared (FTIR) and Thermogravimetric analysis (TGA). [...]

Electrospun Nanofibrous Scaffold for Controll Drug Delivery

Leung V., Hartwell R., Faure E., Yang H., Ghahary A., Ko F., University of British Columbia, CA

This study aims to design methods for controlling drug release from polymer nanofibres, and use these methods as a guide for designing nanofibre wound dressings with customizable release profile for a range of drugs. The [...]

Fast gelation of self-assembling peptide nanofibres triggered by electromagnetic radiation heating

Mazza M., Gaisford S., McCharty D., Uchegbu I.F., The School of Pharmacy, University of London, UK

We report a method for the preparation of peptide nanofibre gels prepared by a rapid heating/cooling cycle employing electromagnetic radiation heating. An amphiphilic peptide having a C16 chain attached via an esteric link was used [...]

Alkoxide-based precursors for direct drawing of metal oxide micro- and nanofibres

Tätte T., Hussainov M., Kelp G., Rand R., Gurauskis J., Lõhmus A., University of Tartu, EE

Metal oxide micro- and nanofibre materials are crucial in numerous technical solutions like textiles, filter mattes, optical cables, thermal insulators, reinforcing components, etc. However, complications to prepare these materials in desired shape often limit their [...]

Preparation and applications of transition metal oxide nanofibres and nanolines

Tätte T., Paalo M., Part M., Kisand V., Lõhmus A., Kink I., University of Tartu, EE

Recently many nanoscale silica structures have been suggested for optics device design. For example silica nanoneedles are used for focusing light into spot some tens of nanometers in diameter and sub-wavelength diameter silica fibres are [...]
