In the new study, Erik van der Linden and colleagues measured the stability of various emulsions prepared from commercial Pernod and compared the results to theoretical predictions of their formation. The scientists found that their experimental observations were often opposite the predicted behavior of the emulsions in the presence of various concentrations of oil, water, and alcohol components. “More knowledge of the parameters that determine the stability of these emulsions, besides interfacial tension, solubility, and density difference, might lead to better control of the emulsification process,” the study states. — MTS

ARTICLE #4 FOR IMMEDIATE RELEASE

New transportation technology for microcargoes
Journal of Physical Chemistry

Scientists in Japan are reporting the discovery of a new transportation technology for moving ultra-small cargoes in the coming generation of micromachines and laboratories-on-a-chip. The report by Kenichi Yoshikawa and colleagues is scheduled for the March 6 issue of ACS’ Journal of Physical Chemistry, a weekly publication.

The study describes successful delivery of a simulated microcargo of paper with chemical waves produced by a reaction that has fascinated scientists and students for 50 years. Termed the Belousov-Zhabotinsky (BZ) reaction, it produces a continuing series of waves in a water solution.

In the report, researchers describe the first use of those waves to move objects in a directed, controlled fashion. “They can be used for the transport of material objects through a desired delivery route,” the report states. “The combination of carrying and controlling waves with the proper timing of initiation allows us, in principle, to deliver freight over a chosen path, with the ability to switch the path if desired.” — MW

Improved polymers for lithium ion batteries pave the way for next generation of electric and hybrid cars
Chemical & Engineering News

The next generation of electric and hybrid cars may be a step closer thanks to new and improved polymer membranes that allow the development of bigger, safer, and more powerful lithium ion batteries, according to an article scheduled for the Feb. 18 issue of Chemical & Engineering News, ACS’ weekly newsmagazine.
