Influence of multiwall carbon nanotubes in mechanical properties of E-glass/epoxy resin/jeffamine-D400 composites

Khoshgoftar M.J., Liaghat G.H., Tarbiat Modares University, IR

Polymer nanocomposites reinforced with carbon nanotubes have attracted recently. The properties of nanocomposites depend greatly on the chemistry of polymer matrices, nature of nanofillers and the way in which they are prepared. Properties of epoxy [...]

Measurement of DPN-Ink Viscosity using an AFM Cantilever

Biswas S., Hirtz M., Lenhert S., Fuchs H., Karlsruhe Institute of Technology, DE

The Dip-Pen Nanolithography (DPN) process uses a chemically coated scanning probe tip (the “pen”) to directly deposit a material (“ink”) with nanometer precision onto a substrate. Several experimental parameters have been observed to influence the [...]

The SURVISMETER – a Green Technology in Service

Singh M., Bhanumati S., Shukla A., Shukla S.S., Shukla A., Shukla S.S., University of Delhi, IN

Viscosity is a measure of stickiness and the reverse is fluidity. It is a valuable data for all liquids in the oil, lubricant, paint, polish, food, beverage, cosmetic, biosolvents, drugs and pharma, polymer, nanomaterials, and [...]

Effect of Sonication on Mechanical Properties of Polymers and Nanocomposites

Sha X., Beyle A., Ibeh C.C., Pittsburg State University, US

This study investigates the influence of sonication on the viscosity and mechanical properties of polymeric nanocomposites. Parameters of study are percentage level of catalyst, temperature level, neat polymer (vinyl ester), nanoparticle [nanoclay] infused polymer (nanocomposite) [...]

Viscosity measurements of PEO solutions by AFM with long nanowires

Hosseini M., Yazdanapanah M.M., Siddique S., Cohn R.W., University of Louisville, US

We recently demonstrated that long metal nanoneedles grown on atomic force microscope (AFM) probes can give very clear measurements of the surface tension, evaporation rate and viscosity of simple liquids. However, in the case of [...]

Galilean Invariant Viscosity Term for an Athermal Integer Lattice Boltzmann Automaton in three Dimensions

Geier M.C., Greiner A., Korvink J.G., IMTEK, Albert Ludwigs University Freiburg im Breisgau, DE

The athermal lattice Boltzmann automata (LBA) are promising replacements for Navier Stokes solvers in computational fluid dynamics (CFD). They are inherently parallel, scale exactly linear with the number of computational elements and can be applied [...]

A Miniature Laser Interferometer for Noninvasive Viscometry

Behroozi F., The University of Northern Iowa, US

A miniature laser interferometer consisting entirely of an optical fiber held in close proximity to a fluid surface is described. The total path difference in this interferometer is less than a millimeter. The interferometer may [...]
