An international collaborative of scientists has devised a method to control the number of optical solitons in microresonators, which underlie modern photonics. Photonics is a dynamically developing field of modern physics. Microresonators are basic structural elements of photonics, an integral part of almost all sophisticated optical and microwave devices. In fact, resonators are circular light traps. Microresonators are currently used for laser...

So-called spatial light modulators that serve as a base for all LCDs, among other things, can be arranged so that each pixel can switch the light quickly, making it brighter or weaker by rotating the polarisation of light. According to Tatyana Dolgova, senior researcher of the Laboratory of Nanophotonics and Metamaterials, Faculty of Physics, MSU, these fast, new spatial light modulators can be used when creating holographic memory, three-dimensi...

An international team of researchers led by Russian scientists has developed a method of using silicon nanoparticles instead of expensive semiconductor materials for certain types of displays and other optoelectronic devices. Lomonosov MSU physicists found a way to "force" silicon nanoparticles to glow in response to radiation strongly enough to replace expensive semiconductors used in the display business.

A group of Russian physicists, with the contribution from their Swiss colleagues, developed a way to use the therapeutic effect of heating or cooling the tissues due to the magnetocaloric effect. The article with the results of the work was published in the latest issue of the International Journal of Refrigeration. A team of the Lomonosov Moscow State University scientists proposed a way to use the magnetocaloric effect for the targeted del...

A team of the Lomonosov MSU researchers in collaboration with their German colleagues from the Institute of Polymer Research in Dresden (Leibniz Institute) believe a particular molecule could lead to the development of organic electronics. The results of the work were published in Advanced Materials. The researchers found that a derivative of [3]-radialene, a molecule known for nearly 30 years, can be used to create organic semiconductors.

Scientists have demonstrated the effect of all-optical switching between streams of photons, born during the third harmonic generation process, using non-linear metamaterials. Researchers at Lomonosov Moscow State University planned the study and conducted calculations and experiments, while their German colleagues made samples of metamaterials. The results are published in Scientific Reports.

Physicists from the Lomonosov Moscow State University have advanced the development of new polymer gels for targeted drug delivery. They have published their results in the Journal of Chemical Physics. "The major outcome of the work is that for the first time a theoretical model was proposed, which laid the basis for analysing the conformational behavior of the hydrophobically modified (HM) polymer gels in a solution of the surface-acti...

An international team including the Lomonosov Moscow State University researchers have determined which enzyme enables Escherichia coli bacterium (E. coli) to breathe. The study is published in the Scientific Reports. Scientists discovered how the E. coli bacterium can survive in the human gut, resolving the mystery of how they breathe. Vitaliy Borisov, senior researcher, explains that E. coli uses special enzymes that are absent in the human bod...

A team of scientists at Lomonosov Moscow State University and the Belarusian National Technical University has created a unique laser. It's a compact light source with wavelengths harmless to the human eye. The device can be used in medicine, communications systems and also in research. The works are published in Journal of Crystal Growth and Optics Letters.
