An Investigation into the Effectiveness of Dielectric Barrier Discharge Plasma for the Transformation of Linear Siloxanes from Gas to Solid Phase

Tahiyat M.M., Heagen L., Hill J., Guyton B., Farouk T.I., Hoque S., University of South Carolina, US

Atmospheric pressure dielectric barrier discharge plasma operating in tetramethyltrisiloxane (L3)-helium gas mixture was studied as a prospective method for the reformation of the organosilicon compounds in the carrier stream. L3 belongs to a family of [...]

Spectroscopic Diagnostics And Material Characterization For Wave Liquefaction™ Processing Of Carbon Materials For The Production Of Value-Added Chemicals And Feedstocks

Vander Wal R., Sengupta A., Musselman E., Zeller K., Skoptsov G., Penn State University, US

1. Optical Diagnostics for Advanced CTL and and GTL Processes H Quest Vanguard is developing broad-spectrum microwave plasma processes targeting conversion of hydrocarbon feedstocks such as coal and natural gas to value-added materials, chemicals and [...]

On the use of polymeric additives to promote plasma separation from whole blood in open microchannels

Lee E., Berthier J., Laurent P., Navarro F., Cubizolles M., CEA, FR

Polymers additives in whole blood are known to modify blood physical properties. For example, Dextran molecules usually accelerate the aggregation of re-suspended RBCs in Ringer solutions. In this work, we first investigate the effect of [...]

Hybrid Processing Method for Fabrication of 3D Layered Nanocomposite Materials

Coulter K.E., Poenitzsch V.Z., DiPietro S., Wei R., Southwest Research Institute, US

Southwest Research Institute and Exothermics Inc. have been developing a hybrid processing method to fabricate macroscaled, layered nanocomposite materials that mimic the structure of nacre. Current research in the biomimetic field is pointing towards importance [...]

Production of hydrogen from various feedstock options using non-thermal plasma catalyzed reforming

Frost L., Hartvigsen J., Elangovan E., Ceramatec Inc, US

Ceramatec has developed a method for reformation of various hydrocarbons using a non-thermal plasma system to catalyze the reformation process. The plasma provides the same type of catalytic activity as a solid catalyst but since [...]

3D Printered and Plasma Treated Superhydrophobic Mesh Filters for Oil-water Separation

Lee H.J., Lee S., Jo W., Lee H.J., Lee S., Moon M.-W., Korea Institute of Science and Technology, KR

We develop the 3D printed mesh filters with plasma treatment using a radio-frequency plasma-enhanced chemical vapor deposition (rf-PECVD) to control their surface wettability. The nano-sclae hairy structures on the meshes are created by plasma etching [...]

Uniform Melt State Process For The Production Of Nanostructured Materials

Redjdal M., Hadidi K., Sundaram S.K., Amastan LLC, US

Existing processes for the production of nanostructured composite materials suffer from non-homogeneity of feedstock and non uniformity of thermal processing path. Amastan’s UniMelt™ process solves both problems through the use of uniform temperature profile microwave [...]

Practical synthesis of nanomaterials and nanostructures

Rae A., Matteson J., Dansoh V., NanoMaterials Innovation Center, US

Nanoparticle and nanostructured coating synthesis is commonly hampered by complex processes or the need to use precursors which may not yet be registered under TSCA or REACH. There are, however, simple and practical processes using [...]

Scalable gas phase nanoparticle treatment methods required for large-scale nanofluid and nanocomposite synthesis

Dion C.A.D., Tavares J.R., École Polytechnique de Montréal, CA

Recent work has demonstrated that while nanofluids do indeed exhibit increased heat transfer properties , there is no abnormal enhancement as had been claimed by early proponents of nanofluids. However, this lack of abnormal enhancement [...]
