Carbon Nanotube Bucky Papers with Tailored Porosity for Filtration Applications

Esawi A.M.K., Ramadan A.R., ElNur R., The American University in Cairo, EG

In this work, Carbon Nanotube Buckypapers (CNT-BPs) were prepared using vacuum filtration. Morphology and pore size distribution were investigated using scanning electron microscopy (SEM) and nitrogen gas adsorption. The prepared BPs were subsequently exposed to [...]

Titania Nanotubes for Separation Applications

Panaitescu E., Ghosh M., Menon L., Northeastern University, US

We investigated the application of titania nanotubes arrays in the form of powders and membranes for water filtration and separation, and for employment in high-performance liquid chromatography. Such membranes have been successfully employed in photocatalytic [...]

Production Technology for Nanofiber Filtration Media

Maly M., Petrik S., ELMARCO, CZ

The theoretical background and technical capabilities of the free liquid surface (nozzle-less) electrospinnig process is described. The process is the basis of both laboratory and industrial production machines known as NanospiderTM and developed by Elmarco [...]

Experimental evaluation of individual protection devices against nanoaerosols:

Golanski L., Rouillon F., Guiot A., Bernard S., Tardif F., CEA, FR

Analysts have estimated that the worldwide market for nanoparticles will be about 340 billion Euro in 2011 which would rank it alongside the automobile and microelectronic industries. However, potential impact of these new materials on [...]

Manufacturable nanoscale membranes – material development and biological separations

Gaborski T.R., Striemer C.C., Snyder J.L., Fang D.Z., Fauchet P.M., McGrath J.L., University of Rochester, US

We have developed a new class of ultrathin porous nanocrystalline silicon (pnc-Si) membranes using inexpensive and scalable silicon fabrication techniques. Pnc-Si is formed from a deposited amorphous silicon thin film, where nanoscale pores are introduced [...]

Nanotechnologies and Health Maintenance

Rae A., NanoDynamics, US

We have all heard about the marvelous advances being made in the use of nanomaterials in imaging, cancer therapy and controlled release pharmaceuticals. What is less well known is the role of nanotechnology in prevention [...]

Purification of PCR-Inhibitory Components by Cellulose Acetate Membranes

Mohamed H., Szarowski D.H., Lepak L.A., Spencer M.G., Martin D.L., Caggana M., Turner J.N., New York State Department of Health, US

Conventional methods for extracting DNA from blood results in the presence of heme, which is an inhibitory factor decreasing PCR sensitivity. Current techniques for removing the inhibitors are laborious, costly, and/or sample-specific. We investigated using [...]
