For several years, Caisa Andersson has been trying to create a better barrier against moisture and oxygen in our food packaging. On December 20, she will submit her doctoral dissertation at Karlstad University in Sweden.
Latex has long been used for various types of surface treatment of paper. In recent years, interest has been focused on the polymer’s characteristic of forming a protective coating on the surface of paper.
“Surface treatment is used to create a barrier against moisture in food packaging. I test different coatings of paper with latex and find out which one yields the best results, what characteristics the barrier layer has. The aim has been to understand what underlying factors determine how a good barrier is formed,” says Caisa Andersson.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
