Malvern Zetasizer Nano supports advances in carbon nanotube synthesis

New research from the University of Padova in Italy shows how the Zetasizer Nano S, a nanomaterial and molecular characterization system from Malvern Instruments, is supporting the development of soluble carbon nanotubes (CNTs).

CNTs exhibit unique electronic, optical, mechanical and structural properties and are emerging as potentially important for a number of industrial applications including organic photovoltaic cells. One of the benefits of using soluble CNTs is that they are amenable to solution-based, low-cost, commercial manufacturing methods. The Zetasizer Nano is proving to be an easy-to-use tool for tracking and optimizing the functionalization reactions used to induce solubility.

FAQ: Peak size or z-average size – which one to pick in DLS?

Written by: Ulf Nobbmann

In dynamic light scattering (DLS) the intensity autocorrelation function of the scattered light is measured. This function is then fit to obtain a size. There are two main fitting algorithms which may confuse users:

Cumulant (or z-average) size and polydispersity (or polydispersity index PDI) with one overall average size and one overall average polydispersity

Peak size (or distribution size) with a mean size and a width for each separate size peak of the distribution

The Periodic Table of Particle Characterization

Written by: Craig Sagar

Whether it is sun washed, stained and tattered, or crisp, pristine and framed, this table adorns labs and classrooms the world over. Some have spent hours on end memorizing all the names, whereas others barely made it past helium. 

Whatever your relationship with science you will have seen a periodic table. It’s the international iconic flag that when hung on a wall says “scientists work here” in less than a second.
