Locating mould and damp in buildings is difficult, sometimes even impossible. The Tekes Fine technology programme explores ways to use the concentration and size distribution of particles to pinpoint mould damage and determine its effect on health. Researchers are also developimg a DNA-based microchip, which can be used for determining the microbes in indoor air rapidly. This is the first experiment where existing medical technologies are being applied to indoor air specimens.
"Up to now, nobody has studied how the concentration and size distribution of particles in the air inside buildings with mould problems differ from those inside healthy buildings. We took measurements in a building with mould problems at all four seasons of the year and measured the effects of repairs on indoor air quality in two buildings", explains Dr. Aino Nevalainen from the National Public Health Institute, who has been leading the research.
"Measurements were also taken in healthy buildings for comparison. The air in the building with mould problems showed inexplicable peaks in particle concentrations that could be caused by damp and mould. Analysis is continuing in those areas."

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...
