At HSE University–St Petersburg, Experts Discuss How AI Changes Tourist Routes and Cultural Heritage
Neural networks are no longer simple travel assistants; now they decide what to include on the route and what to skip. Artificial intelligence changes how people perceive a place and shapes the image of tourist centres. At the II International Scientific and Practical Conference ’Information Technologies in the Preservation and Promotion of Cultural Heritage,’ researchers discussed who controls algorithmic solutions and in what ways, and whether authentic traditions get lost in them.

Road Injuries Leading Cause of Death Among Men Aged 10 to 39
Worldwide, road injuries are the leading cause of death among males aged 10–39. An international team of researchers reached this conclusion as part of the Global Burden of Disease Study 2023, analysing data from 204 countries between 1990 and 2023. Their findings have been published in The Lancet Public Health, with HSE University Professor Vasily Vlassov listed among the collaborators.

ГИДРОТЕРМАЛЬНЫЙ СИНТЕЗ ВОДНЫХ ЗОЛЕЙ НАНОКРИСТАЛЛИЧЕСКОГО ДИОКСИДА ГАФНИЯ, СТАБИЛИЗИРОВАННЫХ МОЛОЧНОЙ КИСЛОТОЙ, И ИХ ЭНЗИМОПОДОБНЫЕ СВОЙСТВА

A method for obtaining aqueous sols of nanocrystalline hafnium dioxide (with hydrodynamic diameter 20-35 nm) stabilised by lactic acid (lactate ions) and characterised by high colloidal stability (zeta-potential -29 mV) has been developed. The method is based on the hydrothermal treatment of a previously obtained complex compound of hafnium with lactic acid in the presence of urea at temperatures of 180 and 220 degrees Celsius for 48 and 96 h. By chemiluminescence analysis in the model reaction of luminol oxidation it was found that nanocrystalline hafnium oxide in the composition of sols exhibits dose-dependent pro-oxidant activity towards hydrogen peroxide and thus exhibits peroxidase-like properties.

Redox behaviour of nanoscale ACe2(PO4)3 (A = NH+4 , K+, Rb+) double ceric phosphates
Kozlova T., Sozarukova M., Kozlov D. et al., Nanosystems: Physics, Chemistry, Mathematics 2026 Vol. 2 No. 17 P. 228–235
A comparative study of the redox behaviour of nanocrystalline isostructural ACe2(PO4)3 (A = NH+4 , K+, Rb+) double ceric phosphates was performed. It has been established that with respect to alkylperoxyl radicals or hydrogen peroxide as reactive oxygen species, all the double ceric phosphates acted as antioxidants or prooxidants, respectively. The antioxidant activity towards alkylperoxyl radicals was found ...

Synthesis of aqueous sols of nanocrystalline hafnium dioxide doped with europium or gadolinium
Новоселова К. Н., Шейченко Е. Д., Попков М. А. et al., Russian Journal of Inorganic Chemistry 2025 No. 70 P. 2158–2164
A method of the synthesis of stable aqueous sols of HfO2 doped with Eu3+ or Gd3+ cations is proposed. It is shown that the introduction of lanthanide cation into hafnium oxide structure leads to stabilisation of metastable tetragonal modification of HfO2. By the method of dynamic light scattering it is shown that HfO2 sols doped ...

Методы детектирования взрывоопасных концентраций водорода: сравнительный анализ и преимущества оптических сенсоров
Кузьминых И. О., Kuzin A., Флоря И. Н. et al., Нано- и микросистемная техника 2025 Т. 27 № 4 С. 184–194
В работе рассмотрены основные варианты детектирования водорода, а также приведены требования, которые предъявляются к сенсорам водорода. Проанализированы преимущества и недостатки существующих решений по детектированию водорода и проведен сравнительный анализ основных метрик коммерчески доступных сенсоров водорода. Было установлено, что оптические сенсоры преодолевают основную проблему существующих сенсоров – использование электрического тока в чувствительной зоне сенсоров. Данная обзорная ...

Synthesis of nanosized phases with a garnet structure using supercritical СО2 fluid
Kolobanov A. I., Fomichev V. V., Sigov A. S. et al., Solid State Sciences 2024 Vol. 157 Article 107710
A method was developed for the production of nanosized complex oxides and oxysulfides. The first stage uses supercritical СО2 fluid (SAS – supercritical antisolvent method). This approach makes it possible to obtain precursor-free complex oxides in a narrow nanoscale range. Nanosized rare-earth iron garnets with the general formula R3Fe5O12, where R is a rare earth ...
