Strictly nanotubes in Beijing

A collaboration between China's leading university and one of the world's biggest industrial companies is bringing a range of nanotube-based materials and devices to the market. The Tsinghua-Foxconn Nanotechnology Research Center (TFNRC) in China is unique in many ways. Located on the campus of the prestigious Tsinghua University in Beijing, it is entirely funded by one of the world's biggest industrial companies Foxconn Technology Group and focuses primarily on carbon nanotubes and related...

Mass spec goes nanomechanical

A new approach to mass spectrometry based on nanoelectromechanical systems removes the need to ionize molecules before their mass can be determined. Mass spectrometry is used to determine the mass of molecules in many areas of biology and chemistry1 because it is fast and generally offers good mass resolution. But mass spectrometers actually measure mass-to-charge ratios, which means that the molecules have to be ionized in the first instance and, moreover, that the charge on the ionized...

Mechanisms for how inhaled multiwalled carbon nanotubes suppress systemic immune function in mice

W. Burchiel2 and J. D. McDonald1 The potential health effects of inhaling carbon nanotubes are important because of possible exposures in occupational settings. Previously, we have shown mice that have inhaled multiwalled carbon nanotubes have suppressed systemic immune function. Here, we show the mechanisms for this immune suppression. Mice were exposed to 0, 0.3 or 1 mg m3 multiwalled carbon nanotubes for 6 h per day for 14 consecutive days in whole-body...
