Metal oxide materials have found wide applications across diverse fields; in most cases, their functionalities are dictated by surface structures and properties. A comprehensive understanding of the intricate features is critical for further design, optimization, applications, necessitating multi-faceted characterizations. Recent advances solid-state nuclear magnetic resonance (ssNMR) spectroscopy significantly extended its detailed analysis multiple metal nanoparticles, offering unparalleled atomic-level information on structures, properties, chemistries. Herein, we present an overview current state art from NMR perspective. We begin with a brief introduction to contemporary ssNMR methodologies. Subsequently, introduce provide reviews different techniques characterizations local disorders, defects, active sites, acidity as well revelation mechanisms behind some intriguing chemistries that occur surfaces, referencing representative recent studies. Finally, address challenges beyond status perspectives future development application advanced methodologies this emerging field.

Мы заканчиваем цикл интервью, посвященный 300‑летию со дня основания Российской академии наук. Сегодня наш собеседник – известный ученый в области физической органической химии и гомогенного металлокомплексного катализа, академик РАН, доктор химических наук, член Европейской руководитель лаборатории Института им. Н. Д. Зелинского РАН (ИОХ РАН), Секции Отделения наук о материалах (ОХНМ РАН) Валентин Павлович Анаников. В дни юбилейных торжеств Валентину Павловичу была вручена медаль «300 лет наук» за большой вклад развитие отечественной науки, подготовку научных кадров, многолетнюю плодотворную научно-исследовательскую организационную работу. поздравляем Валентина Павловича желаем ему успехов благородном труде на ниве науки. О новых тенденциях науке образовании, возрастающей роли искусственного интеллекта машинного обучения, том, насколько важно соблюдать баланс между цифровыми технологиями классическими основами многом другом В. П. Анаников рассказал нашему корреспонденту.

DFT (M06-2X) calculations were used to study the NHC-catalyzed [3 + 3] cycloaddition of enals with aminoacrylates. The catalytic cycle begins binding NHC enal. Subsequent intramolecular proton transfer generates Breslow intermediate. This intermediate undergoes an oxidative reaction, leading formation acyl azolium intermediate, which further reacts other substrate aminoacrylate via a new C–C bond formation. step determines stereoselectivity current and re-face addition mode S-configuration is predominant. Afterward, sequential protonation, deprotonation, cyclization form six-membered cyclic upon elimination affords final product dihydropyridinone. computed enantiomeric excess (99.1% ee) in very good agreement experimentally reported value (99% ee). origin enantioselectivity traced stronger LP···π interactions between favored S-congurational transition state.
