Nanopatterned coatings for advanced glass products

McMackin I., Geddes J., Aryal M., Seitz O., Kobrin B., Rolith, Inc., US

A wide variety of glass products would greatly benefit from coatings that offer anti-reflective, anti-glare, anti-fog, anti-ice, self-cleaning, and other advanced functions. State-of-the-art coatings do not meet desired performance characteristics or cannot be applied over [...]

Patterning of Periodic Structures Using Continuously Moving Stage

Klingfus J., Sanabia J.E., Burcham K.E., Kahl M., Raith USA, US

A unique EBL writing technique is presented which is ideally suited to patterns of a periodic nature such as gratings, holograms, photonic crystals, sieves, etc. In contrast to classic step-and-write EBL strategies, this technique writes [...]

Engineered Nanofluids for Heat Transfer and Novel Applications

Timofeeva E.V., Singh D., Yu W., France D., Argonne National Laboratory, US

Nanofluids are the new expanding area in nanotechnology, with applications as wide as biomedical, lubrication, thermal management, energy generation, energy conversion, and energy storage. Variety and unique characteristics of nanomaterials allow for engineering the multifunctional [...]

Nanofluidics: Wetting and Spreading Phenomena and Applications

Wasan D., Nikolov A., Illinois Institute of Technology, US

Suspensions of nanometer-sized particles in liquids (nanofluids) are used in a variety of technological applications and biological systems. For example, their spreading and adhesion behavior on solid surfaces can yield materials with desirable structural and [...]

Alignment of Different Functional Single Wall Carbon Nanotubes using Fe2O3 Nanoparticles under External Magnetic Field

Younes H., Hong H., South Dakota School of Mines and Technology, US

In this work we describe a new approach to align functionalized single walled carbon nanotubes (SWNTs) by γ-Fe2O3 in the presence of an external magnetic field without using chemical surfactant. Five different functionalized SWNTs are [...]

Modeling Thermophoresis (Soret Effect) in Nanofluids

Eslamian M., Ziad Saghir M., Texas A&M Univeristy- Corpus Christi, US

Thermophoresis plays an important role in forced and natural convection in channels and enclosures when nanofluids are used instead of pure fluids. Therefore, in order to be able to estimate the extent and role of [...]

Nanocarbon Nanofluids: Comparisons Between Morphology and Nanostructure

Vander Wal R.L., The Pennsylvania State University, US

Reported here are experimental results of studies designed to identify the operable mechanisms responsible for the gains in thermal conductivity of nanoﬂuids based on nanocarbons. Comparison of functionalized versus nonfunctionalized nanocarbons addresses the effect of [...]
