Development of a Platinum Nanoparticle based Microcombustor Power Device

Bakrania S., Rowan University, US

Microcombustors coupled with thermoelectric devices have the potential to provide a prolonged power source for portable devices as opposed to conventional batteries due to significantly higher energy densities. Recharging then can be easily achieved by [...]

Soluble Graphene Hybrid Composite (GHC) by Physical Functionalization

Le G.V., Le T.M., Dinh D., Dinh H., Dinh D., Dinh H., Nguyen K.C., Nguyen T.T., Nguyen K.C., Nguyen T.T., Le G.V., Le T.M., DHK GRAPHENOLOGIES LLC, US

Generally speaking, the CVD process of CH4 gas on copper substrate renders a rigid and conductive film from extended graphene molecule which is hard to be produced in large scale. The graphene oxide (GO) is [...]

A New Biocomposite Electrode Sensor for the Detection of Oxidative Reactions

Assan D., Gao X., Lai J.C.K., Leung S.W., Idaho State University, US

Hemoglobin has a very strong affinity with oxygen and thus is a good catalyst to carry oxygen for many oxidation reactions. Many researchers have explored this property of hemoglobin to develop sensors for the detection [...]

Magneto-optic Response of Iron Oxide Nanoparticles under Pulsed and AC Fields

Syed M., Foulkes T., Rose-Hulman Institute of Technology, US

Reliable methods for studying the magnetization dynamics of metal ferrite nanoparticles (NP) are needed, as these particles are attractive candidates for biomedical applications such as in targeted drug delivery, imaging, and magnetic hyperthermia. We investigate [...]

A New Separation Metric for the Optimization of AF4 Separations of Polydispersed Nanomaterials

Galyean A.A., Vreeland W.N., Filliben J.J., Holbrook R.D., Weinberg H.S., University of North Carolina at Chapel Hill, US

The development of standardized and optimized methods to monitor the behavior of engineered nanomaterials (ENMs) in complex environments is considered a critical component in ENM risk assessment. Robust, rigorously optimized methods are currently lacking, in [...]

Fast and Facile Synthesis of Stable and Biocompatible Silver nanoparticles Stabilized by Polyethylene Glycol

Jain S., Singh S., Pillai S., Alabama State University, US

Silver nanoparticles show enhanced properties, when supported onto a substrate and incorporated into organic or inorganic matrix. Their remarkable properties are shape and size dependent. Ethylene glycol and its polymers are environment friendly or environmentally [...]

Surface properties of amorphous nanoporous GeS2

Ori G., Celino M-, Massobrio C., Coasne B., UMI CNRS / Massachusetts Institute of Technology, US

Amorphous nanoporous chalcogenides (chalcogels) represent a novel class of materials with promising properties for applications as catalysts, gas separation, and heavy metal environmental remediation. In the present work, first-principles molecular dynamics (FPMD) simulations are first [...]

Development of a hydroprocessing catalyst containing Boron and Nano-boron compounds

Yonel-Gumruk E., Meric Kartal Berker A., Özcan O., Nilgün Akin A., Turkish Petroleum Refineries Corporation, US

Hydroprocessing is a refinery process of catalytic cracking and hydrogenation of petroleum in order to convert low value heavy hydrocarbons into high value light hydrocarbons and to remove sulphur, nitrogen, oxygen and metals to the [...]

Gold nanoclusters for air purification applications

Mendoza E., Goldemar Solutions, US

Nowadays, public concern and the enforcement of environmental regulations by governments have made it necessary to develop versatile materials capable of efficiently eliminating a wide range of organic pollutants from both indoor and outdoor emissions. [...]

A Green & Clean Process for the Production of Methacrylic Acid and Methacrolein from Biofuel

Lin M.M., Grinberg J., Eng W., EverNu Technology, LLC, US

The modern consumption of fossil fuels for chemical production contributes to global warming and other nature disasters in recent years. Approximately 10% of U.S. crude oil imports are used to feed its chemical industry. There [...]
