A device called “passive chemical dosimeter” will help to identify the quantity of poisonous substances and to determine particular substances inhaled by interlocutors of a smoker. The device is being developed by the Kazan chemists, financial support being provided by the International Science and Technology Center.
The smoking-room of the Lenin State Library – this is the proper place for catching eligible bachelors, as a heroine of the Oscar-winner film “Moscow Does Not Believe in Tears” assured her friend. Alas, as the Kazan chemists claim, this is not the sole thing one can catch in a smoking-room. The device they are developing with sponsorship of the International Science and Technology Center allows to determine the quantity of poisonous substances threatening with oncological diseases got into the organism of any person who was simply sitting the smoking-room for some time. In the future, these will be personal dosimeters – similar to those which allow to promptly determine the radiation dose caught by a person in a radioactive contamination zone.
The concept of operation of chemical dosimeters invented by specialists of the Kazan State Technological University is rather simple. It is necessary to take a plate of a multiple-purpose sorbent applied to an undercoat and to impregnate the sorbent with a special compound. It will react with the compound hazardous to health that are formed in the air in the course of tobacco smouldering. It would be better if reaction products were tinted in different colors. Then, the sorbent’s color and intensity of coloration will help to determine the quantity and the kind of poison a visitor of a smoking-room happened to encounter. And also the dose of these substances a visitor caught during the time (s)he spent in the smoking-room, as it is highly unlikely that (s)he was sitting there in a gas-mask.

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.
To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...
Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
