In a microscopic feat that resembled a high-wire circus act, Johns Hopkins researchers have coaxed DNA nanotubes to assemble themselves into bridge-like structures arched between two molecular landmar...
Creep of thermoplastic polyurethane reinforced with ozone functionalized carbon nanotubes
nanocomposites carbon nanotubes mechanical properties creep
2015/3/30
This work focused on the mechanical behavior, especially creep resistance, of thermoplastic polyurethane (TPU) filled with ozone-treated multi-walled carbon nanotubes (MWCNTs). It was found that the o...
Preparation of fine, uniform nitrogen- and sulfur-modified TiO2 nanoparticles from titania nanotubes
Preparation of fine uniform nitrogen sulfur-modified TiO2 nanoparticles titania nanotubes
2010/11/25
TiO2 nanoparticles modified with nitrogen and sulfur were prepared from titania nanotubes by a facile wet chemistry method. The samples synthesized with different thiourea/TiO2 ratios showed a uniform...
