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.

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.
Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
