Characterization of the Oils of some Non-Edible Seeds as Biodiesel

Osadolor O.O., Clifford O.O., Ambrose Alli University, Ekpoma, Nigeria, NG

In this study, oils of the seeds of Azadirachta indica(Neem), Mangnifera indica(Mango), Thevetia peruviana, Jatropha curcas and Hervia Brasilensis(Rubber) were extracted and transesterified. The oil and biodiesel yields were; Neem, 97%, Mango, 90%, Thevetia 98%, [...]

Controlled Synthesis of Near IR Emitting Metal Chalcogenide Quantum Dots for the Opto-electronic Applications

Hocaoglu I., Eral Dogan L., Dagtepe P., Kuantag Nanotechnologies Development and Production Inc., TR

Studies on the synthesis of Near IR emitting Quantum Dots have increased due to their potential in fiber optic communication systems, in photovoltaic cells, in NIR detectors-cameras, in biological applications including in vitro and in [...]

Characterizing Nanoparticle Emissions from Burning Polymer Nanocomposites

Nyden M.R., Harris R.H., Kim Y-S, Davis R.D., Marsh N.D., Zammarano M., National Institute of Standards and Technology, US

At Nanotech 2009, we presented evidence that CNFs used as fire retardants in polyurethane foam (PUF), were destroyed in the flames and, therefore, were not released when CNF containing foams are burned under well-ventilated conditions. [...]

Evaluating nanomaterial exposures in the workplace: A description of the approach used by NIOSH and a summary of findings from 12 site visits

Hodson L.L., Methner M.M., Geraci C.L., NIOSH, US

Health, safety, and environmental issues continue to be a high priority area to be addressed during the commercialization of nanomaterials or nanomaterial-enabled products (Lux 2008). Facilities engaged in the production or use of engineered nanomaterials, [...]

400-900 nm Light Emitting Silicon Nanoparticles

Liptak R.W., Pi X.D., Kortshagen U., Campbell S.A., University of Minnesota, US

A novel process has been developed to create an aerosol of passivated silicon nanoparticles that emit controlled colors from blue to the near IR. The emission is stable in air. This is the first ever [...]
