This will help scientists and engineers to better understand the properties of light propagating in materials with a hexagonal structure, and use this knowledge in fundamental research and the development of optical devices. Physicists from ITMO took part in this research. The article was published in Nature Photonics.
Solar cells have already become a symbol of modern technologies and fight for the environment. At the same time, the solar power industry is always on the go: manufacturers strive to improve the efficiency of their devices, and scientists and engineers look for ways to produce solar cells that wouldn’t require highly toxic materials. One of such methods has to do with using nanostructures made of carbon, a safe, affordable and reliable material, for producing solar cells’ supplementary layers. A team of scientists that included researchers from ITMO university has recently published a review on the recent advances in this field. ITMO.NEWS spoke to one of its authors, ITMO’s senior researcher Aleksandr Litvin, and learned how carbon helps make solar cells safer and more efficient.
In 2010, Sir Andre Geim was awarded a Nobel Prize in physics for his groundbreaking work on graphene. It was his discoveries that led to the wonder material’s active proliferation in science and industry alike. Prof. Geim continues his revolutionary work on two-dimensional materials as part of his research group in the University of Manchester. The famed scientist presented his latest findings at the 2018 METANANO conference in Sochi and gave this exclusive interview to ITMO.NEWS and Moscow Institute of Physics and Technology’s ‘For Science’ corporate journal, where he talked about why he doesn’t think that lifelong devotion to one scientific field is a good idea, what motivates young researchers to take the leap into fundamental science, and why scholars need to learn to communicate their findings to the wider audience.
Alexander Chezhegov, a third-year student at Lomonosov Moscow State University, Faculty of Physics, took part in the “I am a Professional” competition and the “It’s Your Call!” Winter School that was held at ITMO University last winter. His project focused on creating a hydrophobic coating for solar cells. In July 2018, he did an internship at ITMO’s International Research Center of Nanophotonics and Metamaterials, where he studied hybrid states of light in low-dimensional quantum materials. In his interview with ITMO.NEWS, he shared his experience of working in different research groups.
Over the course of the “Big Challenges” summer camp organized by the Sirius education center, ITMO University’s Faculty of Physics and Engineering lecturers trained promising school students in nanotechnologies research methods. Under the tutors’ helpful guidance, camp participants developed two high-level scientific projects: they created ordered nanostructures arrays for new generation devices and designed a highly sensitive graphene-based gas sensor. By doing that, the young inventors learned to not only follow complex and extremely convoluted scientific instructions, but also to work in teams, be independent in their search for problem solutions, and commercialize their research results.
ITMO University’s Laboratory of Light-Matter Coupling in Nanostructures has begun active research into the optical and electrical properties of two-dimensional materials. Two-dimensional materials are atom-thin structures, graphene being the most well-known example. The laboratory was recently joined by Ekaterina Khestanova, an experimental physicist with a PhD from the University of Manchester, where she studied two-dimensional materials. In an interview with ITMO.NEWS, she talks about her past research and her plans at the laboratory.
How to make a device that can be used to diagnose dangerous diseases? What helped to design a substrate that allows scientists to grow neurons in artificial conditions? And why is it not enough for a scientist to be an expert in only one specific narrow field? We have got an opportunity to discuss these and other questions with Irina Hussainova, an invited researcher at the International Research Center of Functional Materials and Devices of Optoelectronics and Electronics at ITMO University. This year, she was awarded the title of “Scientist of the Year” in Estonia and she has recently come to St. Petersburg to continue joint research. We asked her about the latest trends in the field of biohealthcare and additive technologies, the prospects of cooperating with ITMO and how an opportunity can turn a whole life of a scientist around.
How can one of most widespread materials on the Earth help cure cancer? In what ways are people similar to pigeons? Why oxidize graphene atoms? And why do genes constitute only 20% of the human genome? Scientists gave answers to these and other questions during the recent Science Slam in St. Petersburg; ITMO.NEWS summarized the key points of their presentations.
Last week, the gravitational wave observatory LIGO detected the waves resulting from a merger of a pair of black holes approximately one billion light years away from Earth. Two years ago, the first such discovery caused major excitement in the scientific community. Today, such events seem mundane. Yet, this year’s Nobel Prize in Physics, awarded to the scientists responsible for the LIGO project, shows that this research will remain highly relevant for quite some time. This year’s list of nominees also included those who are trying to explore the qualities of graphene. During an Open Day at ITMO’s Faculty of Physics and Engineering, scientists spoke about the impact that gravity waves and graphene have and will have on both science and everyday life.
