Transient Foaming Behavior of CO2-soluble, Viscoelastic Surfactant in Microfluidic Model, Sand Pack and Limestone Core

Ramadhan G., P. Nguyen Q., The University of Texas at Austin, US

Aqueous foam has been demonstrated through laboratory and field experiments as an effective conformance control technique for gas enhanced oil recovery and carbon sequestration. The use of polymer as an additive to an aqueous foam [...]

Novel Graphene Structures: Substantial Capacity Enhancement in Lithium Batteries

Paronyan T.M., Thapa A.K., Sherihy A., Jasinski J.B., Dilip Jangam S.J., University of Louisville, US

Development of high capacity rechargeable battery anode would significantly improve the advanced energy technologies and enhance the energy efficiency of many economic markets, particularly electric grid storages and renewables. Recently, major research has been directed [...]

The Fabrication and Characterization of Nanocarbon Foam as Novel Wick Material for Thermal Management of Electronics

Li J., Xie J., Zhang M., Florida State University, US

Semiconductor devices have suffered large on-chip temperature gradients due to localized high heat flues resulting from the substantial non-uniformity in power dissipation. To solve the heat problems, the flat heat pipes (HPs) are excellent candidates [...]

Non-destructive imaging analysis of unstable foam structures using 3D computed tomography

Eggert A., Müller M., Nachtrab F., Dombrowski J., Rack A., Zabler S., Fraunhofer Institute for Integrated Systems IIS, DE

Harnessing the resistive-elastic behavior of novel CNT-graphene hybrid foams for practical sensing applications

Wolmarans F., Van H.H., Li S.J., Liu T., Liu T., Zhang M., Florida State University, US

Carbon nanotube (CNT) foam and aerogels hold promise in the area of strain sensors because of their resistive-elastic behavior under compressive strain. To date one of the largest obstacles in the area of CNT foam [...]

Novel 3D Graphene-Based Materials Prepared by Chemical Vapor Deposition: Process Development and Production Scaling-Up

Polyakova E., Stolyarov D., Zhang J., McCarren C., Graphene Laboratories, US

We have developed methods of CVD processing which are suitable for the industrial production of graphene foam. By optimizing the parameters of CVD growth and choosing the proper nickel support structure, we have tuned the [...]

Structure Development in Flexible Polyurethane Foam Nanocomposites

Stanford J.L., Cookson P.A., Fithriyah N.H., Wilkinson A.N., University of Manchester, UK

This research involves in situ studies on the development of molecular and morphological structures during the processing of flexible, water-blown polyurethane foams containing layered silicate (montmorillonite) nanoparticles. Such materials possess enhanced mechanical properties combined with [...]

Controlling the Surfaces of Food: Self-Assembly of Biopolymers

Berg M.C., Mowers W.A., Silberstein S.R., Soane D., DuraFizz, LLC, US

DuraFizz develops and applies nanotechnology-inspired innovations to the food industry by controlling the spontaneous self-assembly of biopolymers at surfaces. This principle is demonstrated in several current research projects including nutrient encapsulation, edible foams, and fryer [...]
