Carbon nanotube photo- and electroluminescence in longitudinal electric fields.

ACS nano

Freitag M, Steiner M, Naumov A, Small JP, Bol AA, Perebeinos V, Avouris P.
PMID: 19928934
ACS Nano. 2009 Nov 24;3(11):3744-8. doi: 10.1021/nn900962f.

The photoluminescence of a partially suspended, semiconducting carbon nanotube that forms the active channel of a field-effect transistor is quenched and red-shifted upon application of a longitudinal electrical (source-drain) field. The quenching can be explained by a loss of...

The exogenous cytokine milieu can influence Th1/Th2 polarization. Besides the differential functional properties, T lymphocytes also acquire distinct profiles of chemokine receptors. Human Th1 lymphocytes preferentially express CCR5 and CXCR3 while Th2 lymphocytes express CCR3, CCR4 and CCR8. After...
