High performance CNT catalyst relating to its electroconductivity

ScienceDaily.com: Nanotechnology News - 16 января, 2018 - 17:56
Biofuels were obtained from Jatropha Oil using carbon nanotube (CNT) catalyst, which showed efficient cracking activity. The performance was activated by the high stability, metal sites, acid sites, electroconductivity, and coking tolerance of CNT. Two cracking circulations were found in the hydroprocessing. Meanwhile, the sulphur-free process was eco-friendly.

Nanofluidics - recent progress

Nanowerk.com - 16 января, 2018 - 17:24
Nanofluidics is the study and application of fluids in and around geometries with nanoscale characteristic dimensions. The field of nanofluidics is not brand-new. Some issues associated with nanoscale fluidics have been occasionally dealt with by researchers in membrane science, colloid science, and chemical engineering for many decades. A recent review article provides a selected overview of the recent progress, rather than a comprehensive review of the entire field.
