The small device invented and developed by the St. Petersburg chemists can be easily hold in hand. It allows to perform real-time control of mercaptans content in petroleum derivatives – these sulfur compounds are extremely undesirable in gasoline.
In general, nobody likes these sulphur compounds. Besides, they reek – but fortunately, we rarely come across this property. More often they play mean tricks remaining unrecognized since even a small doze of these harmful substances is capable of corroding with time through insides of motor-cars, pipelines and practically any tanks coming into long contact with petroleum and petroleum refining products, including gasoline.
Mercaptans – are actually a disguised acid, certainly it is not so strong as sulphuric acid, but it is unsafe for metals. Alas, these compounds are ususally available in petroleum and petroleum refining products, therefore, it is necessary to clean them from mercaptans and to control the refinement quality as precisely as possible.

MPQ scientists achieve long storage times for photonic quantum bits which break the lower bound for direct teleportation in a global quantum network.
Concerning the development of quantum memories for the realization of global quantum networks, scientists of the Quantum Dynamics Division led by Professor...
Researchers have developed a water cloaking concept based on electromagnetic forces that could eliminate an object's wake, greatly reducing its drag while...
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...
