• ITMO Scientists and Colleagues in China, Singapore Devise “Green” Way To Extract Lithium From Used Batteries

  Researchers from Russia, Singapore, and China have created a membrane that can pull lithium out of used batteries with an efficiency of up to 98%. Until now, there hasn’t been an eco-friendly way to recover lithium, even though it’s one of the most important metals for green energy. The new technology helps reduce environmental pollution and is already being put to use at a plant in Singapore. The results of the study have been published in ACS Nano.

• ITMO Researchers Create New Material for Ultrafast Optical Chips and Transistors

  An international team of scientists was first to demonstrate that halide perovskites can serve as a base for nonlinear on-chip optical components. As an example, they can be used to build ultrafast optical chips and transistors, and, potentially, other integrated optical systems. Unlike other materials, halide perovskites can operate at room temperature and are inexpensive to produce. The results were published in ACS Nano and supported by the Priority 2030 program.

• Minimally Invasive Method for Urethral Catheter Cleaning Suggested at ITMO

  A team of researchers from ITMO, Chelyabinsk State University, and Southern Federal University have suggested a new minimally invasive and safe method for the cleaning of urethral catheters. The new approach involves soft magnetic robots that are nearly 100% effective at removing bacteria-containing biofilm from medical devices. Controlled remotely by a magnetic field, the robots will help prevent the spread of infections, reducing the need for frequent catheter replacement, which is a painful procedure. The new method was described in an article published in ACS Nano.

• ITMO Scientists Develop Ultracompact Optical Switch

  The new device includes a structure of single-atom semiconductors and an ultracompact nanoresonator. The switching is conducted with light, via changes in the exciton states in each of the two semiconductor layers. Thanks to its ultracompact size (10 nanometers long and 1.5 nanometers thick), the device can be placed on a chip for use as a logic element in computers for optical information processing. The results of this study, conducted in collaboration with Pohang University of Science and Technology (POSTECH, South Korea), are described in an article published in ACS Nano.

• Cheap and Simple Method of Detection of Harmful Gases Suggested by ITMO Researchers

  Researchers from ITMO and North Ossetian State University have suggested a brand-new cheap and highly sensitive method of detecting hazardous hydrogen halides that are toxic for humans. The new perovskite nanolaser-based method is able to detect dangerous concentrations of various substances that can vary in the range of 5-500 molecules per a million of air molecules. Their suggestion may provide the basis for highly sensitive compact gas leak detectors for the food and chemical industries.

• ITMO Scientists Develop Nanostructured Temperature Indicator Based on Carbon Dots and Nanocellulose

  Researchers from ITMO’s ChemBio Cluster and University of Toronto discovered a nonlinear dependence of photoluminescence of carbon dots on the composition of a water and dimethyl sulfoxide solvent. The color of the same dot sample changes depending on the polarity of solvent it is placed in. Thanks to this discovery, the researchers were able to develop a portable wide-range (from -68°C to +19°C) temperature indicator, which can be used to control the storage conditions of chemical, pharmaceutical, and food products.

• Scientists Grow Optical Chips in a Petri Dish

  The modern photonics industry is constantly working on making its devices more compact, be it computing systems or sensors and lidars. For this, it is necessary to make lasers, transistors and other elements smaller. A team of scientists led by ITMO researchers proposed a quick and affordable method to create optical chips right in a Petri dish. The research was published in ACS Nano.

• Scientists Create Smallest Semiconductor Laser That Works in Visible Range at Room Temperature

  An international team of researchers announced the development of the world’s most compact semiconductor laser that works in the visible range at room temperature. According to the authors of the research, the laser is a nanoparticle of only 310 nanometers in size (which is 3,000 times less than a millimeter) that can produce green coherent light at room temperature. The research article was published in ACS Nano.

• ITMO Researchers Describe Carbon Dot Structure, Discover Red Emission Amplification Method

  Fluorescent carbon nanoparticles, also known as carbon dots, were first described in the early ‘00s. But even today, scientists around the globe still have not reached a consensus on their inner structure and emission process. Carbon dots have a great deal of potential applications due to their biocompatibility with the human body and the ease and low cost of their production as compared to semiconductor quantum dots. Researchers from ITMO University have published two research papers in which they put forth their answers to the burning questions about carbon dots.
