Biofilm as a versatile stablizer and promoter for Pd nanoparticle (PdNP) recovery and catalytic denitrification

Zhou C., Rittmann B.E., Wang Z., Ontiveros-Valencia A., Krajmalnik-Brown R., Arizona State University, US

There is an increasing demand on recycling of palladium from mining waste streams for purposes of resource retrieval and catalytic application. We introduced the novel H2-based membrane biofilm reactor (MBfR) technology to recover Pd in [...]

Fluorescent quantum dot as model imaging probe for studying plant uptake, systemic mobility, localization in plant tissue and potential fate of ultra-small nanoparticles

Das S., Tharkur J., Tetard L., Gesquiere A., Santra S., University of Central Florida, US

Semiconductor fluorescent quantum dots (Qdots) are popularly used as bioimaging taggants in live cell imaging and spectroscopy. In recent years, Qdots taggants are emerging in agricultural applications. Studies are primarily focused on nanotoxicity of ultra-small [...]

Post-Harvest Produce Preservation Using Deep Ultraviolet LED technology

Gaska M. Shur S. Rumyantsev I., Rensselaer Polytechnic Institute, US

With the ever-increasing human population within developing countries, limited availability and access to clean water, ever present climate change call for the coming of a second green revolution. An important component of this second green [...]

L-Arabinose: A Novel Food Ingredient For A Healthier Living

Nolles R., Benschop A., Cosun Biobased Products, US

ABSTRACT (max. 500 words) Introduction More than 35% of the American adult population, equal to 78.6 million people, is reported to be obese, and the US is amongst the top 3 countries in number of [...]

Cellulose Nanocrystals as Barrier Performance Enhancer of Extrusion-Blown PLA Films for Food Applications

Matuana L.M., Karkhanis S.S., Stark N.M., Michigan State University, US

Bio-based plastics from sustainable resources such as biomass are the best alternative to petroleum-based polymers because they provide solutions for reducing the general dependency on oil availability and environmental concerns about the use of common [...]

Surface modification of aluminum doped zinc oxide (AZO) anodes with CFx plasma treatment and nanoscale WOx layers for enhanced electro-optical performance in OLEDs

Kumar Jha J., Santos-Ortiz R., Sun W., Du J., Shepherd N.D., University of North Texas Denton, US

CFx plasma treatment and WOx interfacial layer deposition were performed on AZO films to improve its workfunction for transparent conducting oxide (TCO) anode application in the organic light emitting diodes (OLEDs). As shown in Figure [...]

Use life cycle assessment and risk assessment tools to oversee the development of nanomaterial in building industry

Hu M., Catholic University of America, US

While nanotechnologies offer tremendous benefits for society, they may also pose significant risks. The same properties that make nanomaterial’s promising-those that make them behave quite differently from bulk forms of the same materials-could lead to [...]

Residential Solar Systems as an Appliance Plug and Play PV

Honeker C., Fraunhofer Center for Sustainable Energy Systems, US

The Fraunhofer Center for Sustainable Energy (CSE) has developed a Plug and Play photovoltaic (PV) system, which combines several technologies to dramatically simplify residential solar installation thus reducing soft costs. One enabling concept is the [...]

Crement & Concrete: Where are we going

Jachimowicz F., Westgate P., FJ Consulting, LLC, US

In 2014, 4.2billion tons of cement were used globally to produce about 12billion cubic meters of concrete. As a byproduct, about the equal amount of carbon dioxide, about 4 billion tons, was released into the [...]

Multiscale Modeling and Experimental Study of CO2 Absorption into Ionic Liquid Reverse Micelle

Shi W., Hong L., Kusuma V.A., Hopkinson D.P., National Energy Technology Laboratory, US

Highly viscous solvents for gas absorption will lead to large pumping power requirement and large absorption/desorption tower, resulting in high capital cost. Ionic liquids (ILs) represent such examples even though ILs have been extensively studied [...]
