A new method to accurately measure quantities of a cheese-ripening enzyme in milk could reduce the time and cost of producing cheese, according to a report by Purdue University researchers.

Infrared spectroscopy was used in combination with statistical analysis to determine the concentration of plasminogen, a form of the enzyme integral to cheese manufacturing. The study, by co-authors Lisa Mauer and Kirby Hayes, both assistant professors in the Department of Food Science, is published in the May issue of the International Dairy Journal.
"This method allows us to see how much plasminogen there is in the conditions that were manipulating," said Hayes, a food chemist. "When we combine this information with currently available assays, or tests, for enzyme activity, we can look at both location and activity.

Solar cells based on perovskite compounds could soon make electricity generation from sunlight even more efficient and cheaper. The laboratory efficiency of these perovskite solar cells already exceeds that of the well-known silicon solar cells. An international team led by Stefan Weber from the Max Planck Institute for Polymer Research (MPI-P) in Mainz has found microscopic structures in perovskite crystals that can guide the charge transport in the solar cell. Clever alignment of these "electron highways" could make perovskite solar cells even more powerful.
Solar cells convert sunlight into electricity. During this process, the electrons of the material inside the cell absorb the energy of the light....
Empa researchers have succeeded in applying aerogels to microelectronics: Aerogels based on cellulose nanofibers can effectively shield electromagnetic radiation over a wide frequency range – and they are unrivalled in terms of weight.
