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.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
