• Scientists Propose New Type Of Terahertz Solid-State Laser

  A team of scientists from ITMO and Vladimir State University have proposed a new type of a solid-state terahertz laser. According to their research, such laser will be more efficient compared to existing devices, as well as allow stepless frequency tuning. In future, the proposed model which is based on the use of gallium-nitride quantum dots can lay the groundwork to creating a compact solid-state source of terahertz radiation that can be effectively applied in medicine, security systems, and other fields. The results were first published in ACS Photonics journal, and a separate review of the research was included in Nature’s “News and Views”.

• ITMO Scientists Develop New “White” Near-Field Optical Microscope

  Scientists from ITMO University have proven that a silicon-gold nanoparticle can act as an effective source of white light when agitated by a pulse laser in IR band. One such “nanobulb” was integrated into a standard probe microscope, which allowed the researchers to overcome the diffraction limit and examine subwavelength-size objects. What is more, it made it possible to study the optical response of nanoobjects on the entire visual band, and not just in particular wavelengths. Not only will the new technology make modern near-field microscopy cheaper and simpler, but it also can find use in medicine. The scientists are currently patenting their invention, while its description has recently been published in the prestigious Nano Letters journal.

• ITMO Physicists Use Radiofrequency Trap to “Freeze” Nanocrystals

  A group of physicists from ITMO University has developed a system that provides optical cooling to nanocrystals. The system, made up of a radiofrequency trap and a laser light source, decreases the kinetic energy of a nanocrystal and lowers it to its quantum limit, at which new properties emerge. This method may prove useful in fundamental research and studies of biological objects within the framework of quantum mechanics. A research paper was published in the Journal of the Optical Society of America B as an editors’ pick.

• Scientists Launched a New Method for Microscopy of Nanoobjects

  Scientists have managed to measure the electromechanical properties of nanotubes a thousand times thinner than a human hair. For that, they modified an existing method of the atomic force microscopy so that the scanning probe does not damage nanotubes while moving along a sample surface. The modification helped to study peptide nanotubes loosely attached to a substrate. This technique may prove useful for designing new biocompatible materials and compact devices. The results are published in the latest issue of Ultramicroscopy.

• Russia to Launch First Educational Media-Project on Cancer Prevention

  Cancer prevention foundation “Ne naprasno” (its name translates as "Not in vain" from Russian - Ed.) won a Presidential grant for creating Profilaktika.Media - an educational media project on evidence-based medicine and oncology. Two Master’s students of ITMO’s Science Communication Program are responsible for this project: Ksenia Zhirnova and Elizaveta Dubovik. ITMO.NEWS spoke with these students and found out what it's all about: namely, what is cancer prevention; why there are still so many misconceptions about cancer in Russia; how such a media project could help cancer patients, as well as improve doctors’ training.

• ITMO’s Master's Students Share Experiences from Ireland Internship

  Yulia Andreeva and Elizaveta Anastasova, Master’s students from ITMO’s Department of Food Microingredients Processing and researchers at the SCAMT International Laboratory, have recently returned from their two-month internship at Trinity College (Ireland). In an interview for ITMO.NEWS, the students talk about what made this internship so different from other, more conventional ones, and what opportunities are offered to students by the Erasmu+ program.

• Researchers Use Glass Microparticles to Enhance Solar Cell Efficiency

  Scientists from ITMO University have developed a new solar cell coating based on amorphous silicon that combines the features of an electrode and those of a light-trapping structure. The coating enabled researchers to cut down on reflected light and avoid the overheating of solar cells, thus increasing their overall efficiency by 20%. Moreover, the suggested method is highly suitable for industrial needs due to its relatively low cost and simplicity. The research was published in Optics Letters.
