Aluminum Nanocomposite Materials for Propellant Applications

Chung S.W., Buckner S.W., Jelliss P.A., Place G.J., Laktas J.M., nanoMetallix, US

Aluminum has high applicability in terms of energy release with one of the highest combustion enthalpies of all reactive metals. Thus, the use of aluminum complexes and nanomaterials has been widely researched to develop fuel [...]

Novel Materials for the Desensitizing and Remineralizing Dentifrices

Sereda G., Rashwan K., Karels B., Fritza A., University of South Dakota, US

Modification of the titania surface with organic and inorganic groups can significantly improve the practical potential of this material as a component of toothpastes. Functionalization of titania and silica nanoparticles improves their adhesion to human [...]

Peptide Functionalized Gold and Silver Nanoparticles Inhibit Respiratory Syncytial Virus (RSV) In Vitro

Baganizi D.R., Bawage S., Singh A., Singh S.R., Tiwari P., Dennis V.A., Singh A., Singh S.R., Alabama State University, US

Human respiratory syncytial virus (RSV) is a major cause of severe upper and lower respiratory tract infections in infants, and in high-risk adults. Currently, there is no vaccine and the available therapeutic agents have limited [...]

Characterization of Crosslinked Polymer Nanoparticles by Size-Exclusion Chromatography Coupled to Differential Viscometery

Kalantar T.H., Meunier D.M., Lyons J.W., Kiefer J.J., Niu Q.J., Li Y., Bouck K.J., Tucker C.J., Russo P.S., Cueto R., Dow Chemical Company, US

Conventional size-exclusion chromatography (SEC) and size-exclusion chromatography coupled to differential viscometry (SEC/DV) methodologies have been developed and applied to the dilute suspension characterization of solvent-swollen crosslinked unimolecular polymeric nanoparticles (PNPs) in the 5 ~ 50 [...]

Atmospheric Pressure Spatial ALD onto Powders with Conventional Powder Handling Equipment

Spencer II J.A., Hall R.A., Trujillo-Sullivan K., Groner M.D., ALD NanoSolutions, Inc., US

The manufacturability of ALD coatings on commodity particle substrates requires the development of cost effective ALD processing for industrial scales. We have developed a fully continuous spatial particle ALD system based on conventional powder handling [...]

Graphene Oxide and Reduced Graphene Oxide and Their Water Purification Properties

Baruah B., Baruah S., Kohler G., Baruah B., Baruah S., Kennesaw State University, US

In this study, we synthesized graphene oxide (GO) from graphite with slight modification of literature method. We have deposited purified GO on pure sand to generate GO@sand composite. The GO@sand composite was further reduced chemically [...]

Carbon Nanotubes on Graphene – Interfacial and Electrical Properties

Senegor R., Adesida A., Zhou C., Vyas A.A., Wang P., Yang C.Y., Santa Clara University, US

Continuous downward scaling in silicon integrated circuit technology into the sub-20 nm regime has created critical challenges in chip manufacturing, among them, reliability and performance of on-chip interconnects [1]. Current interconnect materials, Cu and W, [...]

Vertically Aligned Graphene sheets Based Coatings as Nano-micro-structured Electrodes for Enhanced Performance of Supercapacitors

Jang G.G., Keum J.K., Song B., Li L., Hensley D.K., Jiang Y., Hunt A., Moon K-S, Wong C.P., Hu M.Z., Hunt A., Oak Ridge National Laboratory, US

This work develops a molecular engineering approach to control the interspacing of graphene sheets and then an external field approach to induce the re-orientation of the graphene sheets during the deposition process to form a [...]

Strong, controllable, robust, and scalable graphene n-doping for optoelectronic and micro/nano-electronic applications

Folkson J., Ashraf A., Eisaman M.D., Stony Brook University(SBU)/Brookhaven National Lab(BNL), US

Graphene holds promise for many applications such as microelectronics, optoelectronics, and energy storage due to its outstanding properties. The realization of these applications, however, requires tailoring graphene’s electronic properties via controlled doping (addition or removal [...]

The selectivity features of a biological functionalized carbon nanotubes complex towards blood

Cortes P., Fagan D., Olszewki A., Radetic M., Abdallah G., Youngstown State University, US

The present work has studied the selectivity process of a biological complex based on Carbon Nanotubes and a specific amino-acid sequence for interacting specifically with blood. In this work, Human Serum Albumin (HSA) has been [...]
