• Super-nanotubes: 'Remarkable' spray-on coating combines carbon nanotubes with ceramic

  Researchers from the National Institute of Standards and Technology (NIST) and Kansas State University have demonstrated a spray-on mixture of carbon nanotubes and ceramic that has unprecedented ability to resist damage while absorbing laser light. Coatings that absorb as much of the energy of high- more

• High-resolution measurement of photocurrents

  The continuing trend toward miniaturization in electronics demands the use of new materials. Components made of carbon nanotubes may meet this need – and the properties of single nanotube devices can now be characterized with the required resolution. Given the demand for further miniaturization of e more

• Materials: Kitchen sponge used as platform for energy device

  Scientists in Saudi Arabia have used a kitchen sponge as an electrode platform for supercapacitor devices. They made a MnO2–carbon nanotube–sponge supercapacitor electrode that demonstrated reasonably good electrochemical performance in both aqueous and organic electrolytes, they say. They added tha more

• Dramatic enhancement of carbon nanotube dispersion in polyimide composites by a two‐step amino functionalization approach

  ABSTRACT Amino modified multiwall carbon nanotubes (MWNTs) are prepared, respectively, by two ways: the conventional one‐step method that directly treats acyl chloride functionalized MWNTs with 4, 4′‐diaminodiphenyl ether (ODA), giving the amino modified MWNT (Di‐MWNT), as well as an improved tw more

• Tuning Self-Assembled Nanostructures Through Enzymatic Degradation of a Peptide Amphiphile

  The enzymatic cleavage of a peptide amphiphile (PA) is investigated. The self-assembly of the cleaved products is distinct from that of the PA substrate. The PA C16-KKFFVLK is cleaved by α-chymotrypsin at two sites leading to products C16-KKF with FVLK and C16-KKFF with VLK. The PA C16-KKFFVLK forms more
