Nanosilver – Why It is Still So Hot?

Lem K.W., Haw J.R., Lee D.S., Iqbal Z., Salama A., Kurmaran S., Sund S., Curran S., Brumlik C., Choudhury A., Konkuk University, KR

At the present, we are focused on Korean consumer products because in our recent IP landscaping study, we have found that for all major patenting countries, Korea leads in nanosilver applications, with more than 1500 [...]

A proposal of AC corrosion mechanism in cathodic protection

Brenna A., Diamanti M.V., Lazzari L., Ormellese M., Politecnico di Milano, IT

The research proposes an electrochemical mechanism of AC-corrosion in CP condition. Electrochemical tests were carried out on carbon steel in simulated soil conditions to identify AC corrosion risk related parameters during cathodic polarization, like AC [...]

Monitoring volatiles and flammable gases without electronics

Martinez-Hurtado J.L., University of Cambridge, UK

A sensor that integrates the detection and transduction of the signal to a display is presented in this work. The device comprises a holographic grating embed in a polymer. The polymer is an elastomer that [...]

Molecular Effects of Silicon Dioxide Nanoparticles on Cell Survival Signaling of Dorsal Root Ganglion (DRG) Neurons and Schwann Cells

Jain A., Jaiswal A.R., Lu S., Wong Y.Y.W., Bhushan A., Leung S.W., Daniels C.K., Lai J.C.K., Idaho State University, US

The molecular mechanisms underlying the pathophysiology of peripheral neuropathies have not been fully elucidated. To meet the need for suitable cell culture models in vitro of peripheral nervous system (PNS) neural cells that allow long-term [...]

Effects of Silicon Dioxide Nanoparticles on Peripheral Nervous System Neural Cell Models

Jaiswal A.R., Lu S., Pfau J., Wong Y.Y.W., Bhushan A., Leung S.W., Daniels C.K., Lai J.C.K., Idaho State University, US

Cell model systems in vitro facilitate the high through-put screening of putative toxicity of a variety of nanomaterials, including nanoparticles. However, most of such cell models consisted of non-neural cells. We have developed several central [...]

Assessment of comparative toxicity of nano- and microparticles of magnetite

Katsnelson B.A., Privalova L.I., Degtyareva T.D., Kuzmin S.V., Sutunkova M.P., Minigalieva I.A., Kireyeva E.P., Khodos M.Y., Shur V.Y., Nikolaeva E.V., Valamina I.E., Tulakina L.G., Pichugova S.V., Beykin J.B., Federal State Institution of Sciences Medical Research, RU

Assessment of toxicity of 10 nm, 50 nm and 1 um Fe3O4 particles based on shift in the cell population of the broncho-alveolar lavage fluid after their intratracheal instillation into lungs of rats and on [...]

Differential Cytotoxic Effects of Titanium Oxide Nanoparticles on Peripheral Nervous System Neural Cells

Lu S., Jaiswal A.R., Wong Y.Y.W., Bhushan A., Leung S.W., Daniels C.K., Lai J.C.K., Idaho State University College of Pharmacy, US

The health impact of exposure to TiO2 nanoparticles is poorly documented although exposure to the particles is known to elicit inflammatory responses in lung tissue. We recently found treatment with TiO2 micro- or nanoparticles induce [...]

California’s Approach for safe Nanotechnologies: Second Information Call-in from Manufacturers

Kang H.Y., Takatori S., Cal/EPA, US

The California Environmental Protection Agency’s Department of Toxic Substances Control (DTSC) initiated the second chemical information call-in on nanometal oxides (titanium dioxide, cerium oxide, and zinc oxide), nanometals (silver and zero valent iron), and quantum [...]

A novel technique for toxicological characterization of engineered nanomaterials

Demokritou P., Sotiriou G.A., Diaz E., Godleski J., Brain J., Pratsinis S.E., Harvard University, US

How do we balance the potential hazards from new and inadequately characterized engineered nanomaterials with the potential and power of nanotechnology? It has become apparent, that potential environmental health effects are critical factors in the [...]

The Development of a Portable Arsenic Detector Based on Surface-Enhanced Raman Spectroscopy for Rapid on-Site Testing of Groundwater

Wang K.Q., Wang Y., Pan G., Wang K.Q., Wang Y., Agiltron, Inc., US

The combination of high toxicity and widespread occurrence has created a pressing need for effective monitoring of arsenic in groundwater. Although laboratory analysis has been used to measure arsenic in collected groundwater samples, the time [...]
