A New Gas/Supercritical Fluid (SCF) Diffusivity and Solubility Measurement Method for CO2 Saturated Polymer Systems Using Optical Transmission Property

Yao S.X., Lee J-K, Lee J., Lee P-C, Lee J-K, Lee J., Lee P-C, Jun M.B.G., Lee J-K, Lee J., Lee P-C, University of Vermont, US

Supercritical fluids (SCFs) and gases are widely used in polymer processing. For example, plastic foam products used for light-weight structural components, heat insulation, and food packaging can be fabricated by nano-/micro-cellular foaming processes with gases [...]

NETZSCH Nanotechnology Advancements and Applications

Miranda S., Smith R., NETZSCH Premier Technologies, US

Size reduction into the nanometer size range offers many advantages. These include increased surface area, improved reactivity, efficient absorption and higher efficacy of active ingredients. This presentation will discuss methods for Comminution and dispersion of [...]

A New and versatile method for preparing crystalline drug nanoparticle formulations

Higgins J.D., Merck Research Labs, US

The birth of the nanoparticle (nanos) drug delivery field arguably was seen over 20 years ago with the advent and application of simple oral crystalline nanoparticle formulations. This effective approach for enhancind oral absorption using [...]

Molecular dynamics simulation of the transport of H2, O2, Ar, CH4 and n-C4H10 in composite poly (4-methyl-2-pentyne) and nanoparticle of cristobalite silica and faujasite silica

Yang Q., Achenie L.E., Virginia Tech, US

In industrial processes membranes made of composite polymer material are widely employed to separate gas mixtures. These membranes have better performance than membranes consisting of polymer alone. To understand the mechanism and therefore aid membrane [...]

Water Soluble Carotenoid Conjugates with Oligo- and Polysaccharides. Synergy of Drug Transport and Efficacy

Polyakov N.E., Leshina T.V., Meteleva E.S., Dushkin A.V., Konovalova T.A., Kispert L.D., University of Alabama, US

We present first example of water soluble conjugates of carotenoids with a triterpene glycoside, glycyrrhizic acid (GA), and natural polysaccharide arabinogalactan (AG), studied by various physicochemical techniques. Carotenoids are well known as a class of [...]

Graphene and polymer composite using easy soluble expanded graphite

Lee J-H., Sungkyunkwan University, KR

ESEG was prepared from a fluorinated graphite intercalation compound (FGIC) - C2F∙nClF3 containing inorganic volatile intercalating agent ClF3. The severe expanded state, together with high specific surface area of the ESEG can give us essential [...]
