Researchers Discover How Spelling Errors Slow Down Reading in Russian
Psycholinguists from the Centre for Language and Brain at HSE University–St Petersburg have shown that words that are frequently misspelled are processed more slowly by readers, even when presented with the correct spelling. The researchers confirmed this effect for the first time using Russian-language materials and found that response speed is most strongly linked to how confidently individuals can distinguish the correct spelling of a word from an incorrect one. The study has been published in The Mental Lexicon.

HSE Develops App for Assessing Phonological Processing in Children
Researchers at the HSE Centre for Language and Brain have developed a new digital tool for assessing children's phonological processing skills—the ZARYA (Sound Analysis of the Russian Language) test battery. It is the first standardised application in Russia designed to provide a fast and reliable assessment of children's ability to distinguish speech sounds, retain them in working memory, and perform phonemic analysis. The app runs on Android tablets and smartphones and is available for download from RuStore. Details of the test validation have been published in the Journal of Speech, Language, and Hearing Research.

Scientists Discover Why Europium 'Misbehaves'
Europium is a rare-earth metal responsible for the pure red glow in displays and other luminescent materials. For a long time, however, it refused to emit light when surrounded by certain organic molecules known as acylpyrazolone ligands. Chemists have now uncovered the reason: in europium complexes with these ligands, a 'black window' appears—a charge-transfer state in which the energy absorbed by the ligand is dissipated as heat rather than emitted as light. Understanding this mechanism opens the way to designing more efficient red-emitting materials for displays, fluorescent thermometers, and chemical sensors. The results have been published in Dalton Transactions.

Research of Surface Wear Resistance of Aluminum Alloy Modified with Minerals using Sclerometry Method

Devices and Methods of Measurements (Belarus). 2019. Vol. 10. No. 3. P. 263–270.
Skazochkin A. V., Bondarenko G.G., Żukowski P.

A comparative study of the wear resistance, hardness and modulus of elasticity of ENAW-2024 aluminum alloy samples with and without a mineral coating was carried out. The wear resistance of the samples was studied by the method of multi-cycle friction, which makes it possible to measure the physicomechanical properties of thin modified material layers at the nanoscale. After the modification of the sample surface, the surface hardness and elastic modulus decreased by 20–36% and by 22–38%, respectively. At the same time, the wear resistance of the surface of the sample, modified by minerals, increased by more than 12 times compared with the wear resistance of the surface without modification. The parameters of the modified surface of the aluminum alloy, measured by sclerometry, can be further used to construct models of the surface modified by ultrafine mineral particles and to calculate the processes of friction and wear.
