Three-dimensional Core@Shell Nano-Array Electrodes for Integrated Lithium-Ion Microbatteries

Mao Y., Sun X., Li Q., Lv Y., University of Texas-Pan American, US

In micro/nanoelectromechanical systems (MEMS/NEMS) and biomedical devices, the desired on-board power storage and delivery occur in exceptionally small geometric scales, where amount of energy stored on given footprint (J/mm2) precedes that in either unit weight [...]

Inhibitory effects of titanium dioxide, silver and fullerene nanoparticles on activated sludge from a municipal wastewater treatment plant

Aude Luppi V., Fidalgo de Cortalezzi M.M., Instituto Tecnologico Buenos Aires, AR

The possibility of negative impacts of three nanomaterials on an aerobic heterotrophic microbial community (activated sludge) was investigated through respiratory inhibition tests (OECD 209 protocol). Titanium dioxide (TiO2NP, Evonik P25), silver (AgNP, synthesized in the [...]

Risk Ranking Framework to Assess the Health Hazard of Nanomaterial-Containing Products in an Industrial and Consumer Application Setting

Madl A.K., Unice K., Kreider M., Kovochich M., Bebenek I.G., Abramson M.M., ChemRisk, US

The unique combination of size, structure, morphology, physical/chemical characteristics, and quantum properties of nanomaterials, presents a challenging platform in understanding the potential hazards and health risks of engineered nanomaterials and the products that utilize these [...]

Bio-compatibility of silver nanomaterials using the embryonic zebrafish bioassay

Fisher J.A., Tanguay R.L., Oregon State University, US

The bio-compatibility of silver nanomaterials (AgNP) is currently of great interest to regulators and health and safety professionals because it is a material that has the potential to reach mass populations. Four well characterized (Harper [...]

Effects of CdTe QDs on protein structural changes

Ma X., Liang X., Liu L., Hu X., Fan J., Northwest University, CN

The nano-scale material, quantum dots (QDs), has been widely used in biological labels, imaging of fixed cells and tissues due to their excellent properties, such as small size, large surface area, good photostability, and negligible [...]

Nanomaterials-Enabled Photonic and Chemiresistive Sensing of Chemicals and Biochemicals

Choi C-J, Benkstein K.D., Rogers P.H., Montgomery C.B., Semancik S., National Institute of Standards and Technology, US

Contact events occurring between target species and surface sites on sensing materials initiate front-end interactions and subsequent transduction processes that can yield viable signals for target detection. By offering high surface-to-volume ratios, and specialized properties, [...]

Scalable Manufacturing of Nanopowders by Solution Combustion Processing

Venugopal G., Dressler D., Webster D., Johnson S., Stieha J., Brandenburg T., Hunt A., nGimat LLC, US

For the past several decades, gas-phase combustion processing has been used to produce nanomaterials like titanium dioxide and carbon-black in tonnage. These processes are restricted to the production of simple, single-element or single-metal compositions, primarily [...]

1D Multi-Structured Micro/nanomaterials with Special Wettability

Zhao Y., Beihang University, CN

With the progresses in material sciences, the generation of microscopic materials experiences an architectural evolution process from simple to complex. The complex interior structures will enable such materials a number of potential applications. Here we [...]

A Novel Catalytic Synthesis Method of Carbon Nanomaterials in the Organic Liquids

Gamo H., Nishitani-Gamo M., Ando T., Nishitani-Gamo M., Toyo University, JP

We have developed a novel catalytic method for synthesizing a wide variety of carbon nanomaterials in the organic liquids. There is no need for a vacuum reactor. The method realized a simple, speedy, and a [...]
