Nanosize Iron Oxide for CO Oxidation

Wu Z., Fransson M., Zhou B., Headwaters Technology Innovations LLC, US

Transition metal oxides are desirable alternatives to precious metals based catalysts for CO oxidation since they are less costly. Several nanosize iron oxides were prepared by using Headwaters Technology Innovation (HTI) NxCat® colloidal chemistry nanotechnology. [...]

Nanomaterials down the drain: perception and reality

Sellers K., Bergeson L.L., AMEC, US

The fate of nanoparticles in commercial products at the end of product life is not entirely clear. This uncertainty, coupled with the unknowns regarding the potential for risks to human health and the environment, could [...]

Nanofiltration of Electrolyte Solutions by Sub-2nm Carbon Nanotube Membranes

Fornasiero F., Park H.G., Holt J.K., Stadermann M., Kim S., In J.B., Grigoropoulos C.P., Noy A., Bakajin O., Lawrence Livermore National Laboratory, US

Both MD simulations and experimental studies have shown that liquid and gas flow through carbon nanotubes with nanometer size diameter is exceptionally fast. For applications in separation technology, selectivity is required together with fast flow. [...]

Environmental and Economic Assessment of Nano-Fabrication Processes of Memory Devices

Dahlben L., Isaacs J.A., Northeastern University, US

The unique mechanical, electronic, and non-volatility of carbon nanotubes (CNT) have significant potential to replace current silicon-based switches. However, before fully integrating CNT switches into the semiconductor industry, the production costs and environmental impacts associated [...]
