Cerium Glows Yellow: Chemists Discover How to Control Luminescence of Rare Earth Elements

Cerium Glows Yellow: Chemists Discover How to Control Luminescence of Rare Earth Elements
Researchers at HSE University and the Institute of Petrochemical Synthesis of the Russian Academy of Sciences have discovered a way to control both the colour and brightness of the glow emitted by rare earth elements. Their luminescence is generally predictable—for example, cerium typically emits light in the ultraviolet range. However, the scientists have demonstrated that this can be altered. They created a chemical environment in which a cerium ion began to emit a yellow glow. The findings could contribute to the development of new light sources, displays, and lasers. The study has been published in Optical Materials.

Chemists Simplify Synthesis of Drugs Involving Amide Groups

The resulting product (Vorinostat component) without purification
Chemists from HSE University and the Nesmeyanov Institute of Organoelement Compounds of the Russian Academy of Sciences (INEOS RAS) have developed a new method for synthesising amides, essential compounds in drug production. Using a ruthenium catalyst and carbon monoxide under precisely controlled reaction conditions, they successfully obtained the target product without by-products or complex purification steps. The method has already been tested for synthesising a key component of Vorinostat, a drug used to treat T-cell lymphoma. This approach could lower the cost of the drug by orders of magnitude. The paper has been published in the Journal of Catalysis. The study was supported by the Russian Science Foundation.

Russian Scientists Develop New Compound for Treating Aggressive Tumours

Russian Scientists Develop New Compound for Treating Aggressive Tumours
A team of Russian researchers has synthesised a novel compound for boron neutron capture therapy (BNCT), a treatment for advanced cancer that uses the boron-10 isotope. The compound exhibits low toxicity, excellent water solubility, and eliminates the need for administering large volumes. Most importantly, the active substance reaches the tumour with minimal impact on healthy tissues. The study was published in the International Journal of Molecular Sciences shortly before World Cancer Day, observed annually on February 4.

Russian Scientists Improve Water Purification Membranes Using Metal Ions

Russian Scientists Improve Water Purification Membranes Using Metal Ions
Researchers have proposed using polymer membranes modified with copper, zinc, and chromium metal ions for water purification. These polymers were used for the first time in water purification via electrodialysis. Copper-based membranes demonstrated record selectivity for monovalent ions, opening new possibilities for sustainable water recycling. The study has been published in the Journal of Membrane Science

'I Would Ask Mendeleev if It's True that He Invented Vodka'
Andrey Manin's research focuses on membranes, but he has not yet decided whether to dedicate his PhD thesis to those used in water desalination or those involved in new types of electricity generation. In this interview with the HSE Young Scientists project, he recalls how he once disliked organic chemistry, enjoys watching retro films at Illusion Cinema, and was fascinated by Red Square as a child.

HSE Faculty of Chemistry Professor Wins Vyzov Prize

HSE Faculty of Chemistry Professor Wins Vyzov Prize
On December 9, 2024, the winners of the Vyzov Prize for Future Technologies were announced. Professor Leonid Fershtat from the Joint Department of Organic Chemistry with the RAS Zelinsky Institute of Organic Chemistry was honoured in the ‘Future’ category for his advanced research on creating functional organic materials for multi-purpose use based on high-nitrogen molecular architectures.
