Iron-sequestering molecules play a pivotal role in the mechanism of toxicity of SWNTs on fungal and bacterial cells

Chaves J.S., Chaves S.J., Zuniga P., Chaves J.S., Chaves S.J., Instituto Tecnologico de Costa Rica, CR

In this study we described that iron-sequestering molecules are responsible for the toxicity of iron containing SWNTs to microorganisms. After incubating different concentrations of functionalized SWNTs with bacteria and fungal cells, it was found that [...]

Carbon Nanotube Thin Film based Fuel Cell to Reach DOE Targets

Palanisamy R., Itkis M.E., Bekyarova E., Haddon R.C., Carbon Solutions Inc, US

We demonstrate a prototype polymer electrolyte membrane fuel cell (PEMFC) that reaches the technical targets set by DOE for 2015. We show that the Pt required for automotive fuel cells can be reduced by an [...]

Structure and Electronic Properties of “DNA-Gold-Nanotube” Systems: A Quantum Chemical Analysis

Pannopard P., Sirijaraensre J., Nokbin S., Khongpracha P., Limtrakul J., Kasetsart University, TH

The idea of chemical sensing based on molecular recognition is known as one of the most promising concepts for single-molecule detection, even though it still remains in an early developmental stage. The approach requires probes [...]
