Magna Imperio Systems: Innovating Solutions Through Technology

Page G., Magna Imperio Systems, US

Fresh, potable water is a sacred, yet scarce, resource that brings life to the world. The successful foundation of every community is reliant on the crucial interconnected relationship between water, food, and energy known as [...]

H2 purification with PVDF/GTA blended membranes

Rabiee H., Soltanieh M., Mousavi S.A., Ghadimi A., Sharif University of Technology, IR

In this study, poly(vinylidene fluoride) (PVDF) and Glycerol Triacetate (GTA) have been selected as the main blending materials in order to fabricate membranes with a high separation ability for CO2/H2. GTA as a plasticizer possesses [...]

Purification of EBID structures of noble metals by electron beam post-irradiation under oxygen flux

Mehendale S., Mulders J.J.L., Trompenaars P.H.F., FEI Electron Optics, NL

Although Electron Beam Induced Deposition (EBID) is considered as a single-step process for creation of three-dimensional nanostructures of different materials, direct deposition of highly pure metallic structures had been rarely achieved. Typically, use precursors such [...]

Purification of Nanoparticles by Hollow Fiber Diafiltration

Bianchi D., Serway D., Tamashiro W., Spectrum Laboratories, US

Hollow Fiber Diafiltration (or Hollow Fiber Tangential Flow Filtration) is an efficient and rapid alternative to traditional methods of nanoparticle purification such as ultracentrifugation, stirred cell filtration, dialysis, or chromatography. Hollow Fiber Diafiltration can be [...]

A Novel Technique for Purification and Segregation

Mangir T., Chaves J., Chaves S., Khairatkar M., Chaves J., Chaves S., California State University Long Beach, US

In paper we describe a technique to purify and segregate carbon nano tubes (CNTs) from the iron impurities to use the CNTs for thin films. After extensive research into a proper and repeatable cleaning process [...]

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 [...]

Design of Magnetic Nanoparticles for Purification of His-tagged Recombinant Proteins

Mohapatra S., Pal D., Ghosh S.K., Pramanik P., Indian Institute of Technology, IN

Manipulation of proteins effectively for in-vitro study is an important step of research in the area of proteomics. The expression of recombinant proteins with histidine fusion tags(6xHis) is widely used to ease their purification from [...]

Sidewall Functionalization of Single-Walled Carbon Nanotubes through C-N Bond Forming Substitution Reactions of Fluoronanotubes

Stevens J., Kini V.U., Huang A., Chiang I.W., Derrien G.A., Khabashesku V.N., Margrave J.L., Rice University, US

Because of the high reactivity of C-F bonds on the sidewalls of single-wall carbon nanotubes, fluorinated SWNTs (fluoronanotubes) can be used as precursors for further derivatization. One such reaction is to replace the fluorine with [...]
