Expedient synthesis of heterocycles and methyl sulfonyl compounds via C-X BONDS (X = O, N, S) construction by Jiang, Yaojia

“…In chapter 3, we have described two methodologies to synthesize multi-substituted pyridines from rhodium-catalyzed nitrene reaction and DBU-mediated ring opening of 2-allyl-2H-azirines. In chapter 4, we have described a radical strategy promoted by copper, oxygen and HPO(OEt)2 for the difunctionalization of alkenes to synthesize β-keto methyl sulfones; meanwhile, we have also demonstrated that alkynes could be directly undergo methyl sulfonylation to afford (E)-vinyl methyl sulfones through modification of the reaction condition.…”

Controlling Cherenkov angles with resonance transition radiation by Lin, Xiao, Easo, Sajan, Shen, Yichen, Chen, Hongsheng, Zhang, Baile, Joannopoulos, John D., Soljačić, Marin, Kaminer, Ido

“…However, since the Cherenkov angle depends only on the material’s permittivity, the material unavoidably sets a fundamental limit to the momentum coverage and sensitivity of Cherenkov detectors. For example, ring-imaging Cherenkov detectors must employ materials transparent to the frequency of interest as well as possessing permittivities close to unity to identify particles in the multi-gigaelectronvolt range, and thus are often limited to large gas chambers. …”

Magnetism of two-dimensional chromium tellurides by Yang, Jiefu, Zhu, Chao, Deng, Ya, Tang, Bijun, Liu, Zheng

“…2D ferromagnets have garnered considerable attention for their potential applications in spintronics, magnonics, and spin-orbitronics. Chromium tellurides (CrxTey), in particular, have drawn interest due to their exceptional magnetic properties and diverse range of chemical stoichiometries, attributed to the phenomenon of chromium self-intercalation. …”

Electric field modulation of the tetragonal domain orientation revealed in the magnetic ground state of quantum paraelectric EuTiO3 by Kato, Y., Sunku, S. S., Ito, T., Spalek, L., Shimuta, M., Katsufuji, T., Saxena, S. S., Batista, Cristian D., Petrovic, A. P., Sengupta, Pinaki, Panagopoulos, Christos

“…Our experimentally determined magnetic phase diagram is accurately reproduced by a three-dimensional (3D) anisotropic Heisenberg spin model. Furthermore, we demonstrate that electric field cooling acts to suppress this orientational disorder by realigning the domains due to the strong coupling between electric fields and lattice dipoles characteristic of paraelectric materials.…”
