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.

Nowadays energy conversion in lighting and optoelectronic devices requires the use of rare earth oxides.
Scientists have discovered the first synthetic material that becomes thicker - at the molecular level - as it is stretched.
Researchers led by Dr Devesh Mistry from the University of Leeds discovered a new non-porous material that has unique and inherent "auxetic" stretching...
Scientists from the Theory Department of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science (CFEL) in Hamburg have shown through theoretical calculations and computer simulations that the force between electrons and lattice distortions in an atomically thin two-dimensional superconductor can be controlled with virtual photons. This could aid the development of new superconductors for energy-saving devices and many other technical applications.
The vacuum is not empty. It may sound like magic to laypeople but it has occupied physicists since the birth of quantum mechanics.
