A highly durable and moreover self-lubricating material has seen the light of day at a thin film laboratory at Linköping University.
It is an alloy of boron suboxide and yttrium, BOY, and was grown by the physicist Denis Music. The discovery is put forward in his doctoral dissertation.
The element boron and its compounds have many interesting properties, but they have been difficult to exploit industrially because production involves extreme process conditions. To produce a crystal of boron suboxide requires a temperature of 2000 degrees and extremely high pressure. Denis Music solved the problem by adding the metal yttrium, and, using thin film technology, managed to create a crystalline surface layer of the materal at a mere 300-400 degrees.

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...
