Quick Cook Method Turns Algae into Oil :: NASA Tech Briefs
' Michigan Engineering researchers can "pressure-cook" algae for as
little as a minute and transform an unprecedented 65 percent of the
green slime into biocrude. "We're trying to mimic the process in nature
that forms crude oil with marine organisms,"

Characterization of magnetic nanodispersions by multisample analytical centrifugation, DLS and electrokinetic potential
magnetic nanodispersions - Partec 2013
Multisample analytical centrifugation with high resolution photometric detection was applied to characterize the quality of differently stabilized magnetic nanodispersions. Results were compared with hydrodynamic size and zeta potential obtained by dynamic light scattering technique. Comparison of the ‘fingerprints’ gives a fast overview over differences in quality of magnetic nanodispersions (quality of particle stabilization against aggregation and separation stability). Sedimentation kinetics and distribution of sedimentation velocities allow for a more detailed quantitative comparison and ranking between different products and batches. The velocity distribution, which does not require any material properties to be known, can be used as an integral measure of separation stability. The magnetic nanodispersions are highly stable; separation at higher centrifugal acceleration is reversible when acceleration is lowered. This effect is enhanced in case of electrostatic repulsion between particles.
