• ITMO Researchers Discover Crystals That Imitate Brain Cell Activity

  Scientists from ITMO University have discovered that when subjected to laser pulses, hybrid crystals behave like neurons in the brain: their reaction to light is analogous to that of neurons to triggers. Such crystals can serve as a basis for devices that work as biological neural networks – thus making it possible to train artificial neural networks more quickly and efficiently. The suggested crystals are made from harmless domestically made materials and are easy to manufacture. The results of the study were described in Communication Materials (part of the Nature journal family).

• ITMO Researchers Use Hybrid Crystal to Enable Simultaneous Grayscale and Color Direct Laser Writing

  With the new material suggested by ITMO physicists, it will be possible to embed grayscale images into color ones during direct laser writing. The researchers were the first to use metal-organic frameworks for the purpose; these are optically transparent materials that can transform laser radiation. When subjected to it, the material’s structure changes, with color defects formed inside. Each such defect has a unique scattering spectrum, making metal-organic frameworks useful in producing uncloneable anti-counterfeit trademarks. The material is described in a paper published in Advanced Functional Materials.

• ITMO Physicists Suggest Method for Mass Production of Metal-Organic Frameworks for Gas Sensors

  The detection of harmful gasses during production is made possible with gas sensors. A promising method of manufacturing these devices involves 2D metal-organic frameworks (2D MOFs). These are special porous hybrid materials with features that make them excellent sensors. Scientists from ITMO University have suggested a new production method that would result in 2D MOFs of record length and thinness – not only in lab conditions, but on industrial scale, too.

• ITMO Scientists Suggest Efficient Microfluidic Synthesis for Metal-Organic Frameworks

  Nowadays, metal-organic frameworks (MOFs) are actively studied and used for cleaning and detection purposes, as well as for recording and storage of data. For the most part, they’re synthesized using conventional methods, which require lots of resources. As an alternative, scientists from ITMO’s School of Physics and Engineering suggest a quicker and more efficient method – microfluidic synthesis of metal-organic frameworks using chips. Potentially, it can be used for targeted drug delivery.

• ITMO Researchers Suggest All-Optical Data Processing Method Using Heating

  Metal-organiс frameworks (MOFs) are a new class of compounds that is famous for its unique properties. They have been considered a functional material for gas adsorption, industrial membranes, and catalysts; however, researchers from ITMO have gone further and decided to zone in on MOFs’ optical properties. In a recent paper, they demonstrated that thanks to MOFs’ flexibility, these properties can be changed when subjected to lasers. This new effect can pave the way for all-optical data encoding, transfer, and storage.

• How New Advanced Materials Help Fight Bacteria – and Cancer

  Gary Hix is a professor of the University of Wolverhampton (the UK) and the head of Wolverhampton School of Sciences. Together with his research team, Prof. Hix designs anti-bacterial medical materials. In an open lecture at ITMO University, he spoke about organic-inorganic hybrid materials, metal phosphonates and oxides, and how these substances are produced. Speaking about anti-bacterial materials, Prof. Hix explained the effect of their structure on the discharge of active substances and how these materials are made to possess therapeutic qualities.

• Forming Bonds: Visiting Scientists on Chemistry Research and Working Abroad

  Two young extraordinary scientists with extensive international experience – a chemist and a materials science engineer – came to ITMO to conduct research for a few months. They currently work in the Hey-Hawkins Group at the Institute of Inorganic Chemistry at Leipzig University. Sara Durini is a postdoc from Italy and Rafaella Precker is a Ph.D. student from Brazil. They both took part in research at the Solutions Chemistry of Advanced Materials and Technologies (SCAMT) Laboratory at ITMO. The international news portal had an exclusive interview with them to learn more about their research.
