One-pot, four-component procedure for the synthesis of a small library of new chiral spiro- oxindolopyrrolidines with high regio-, diastereo- (>99:1 dr), and enantioselectivity (up to 80% ee) is described. In this process, the regio- and stereochemical 1,3-dipolar cycloaddition of azomethine ylides, which were generated insitu by the reaction of isatin derivatives and sarcosin,with optically ac...

A composite chiral metamaterial (CCMM) is designed and studied both numerically and experimentally. The CCMM is constructed by the combination of a continuous metallic wires structure and a purely chiral metamaterial (CMM) that consists of conjugated Rosettes. For the CMM, only very small, useful bands of negative index can be obtained for circularly polarized waves. These bands are all above t...

We consider the Ising model on a cylindrical lattice of L columns, with fixed-spin boundary conditions on the top and bottom rows. The spontaneous magnetization can be written in terms of partition functions on this lattice. We show how we can use the Clifford algebra of Kaufman to write these partition functions in terms of L by L determinants, and then further reduce them to m by m determinan...

Nonlinear topological photonics, which explores topics common to the fields of phases and nonlinear optics, is expected open up a new paradigm in photonics. Here, we demonstrate second-harmonic generation (SHG) via interaction double valley-Hall kink modes all-dielectric photonic crystals (PhCs). We first show that two frequency band gaps can be created around pair frequencies, ${\ensuremath{\o...

We investigate inhomogeneous chiral condensation under rotation considering finite size effects and boundary conditions in the holographic QCD model. The rotational suppression effect determined by $\mathrm{\ensuremath{\Omega}}r$ is confirmed model which not influenced conditions. For at center, it found that Neumann condition exhibits two opposite effects, i.e., catalysis high temperatures inv...

background: omega-3 fatty acids have established beneficial effects for cardiovascular disease. the use of omega-3 supplements for patients with non-alcoholic fatty liver disease (nafld) was proposed. the purpose of this study was to review the relationship between omega-3 fatty acids intake and nafld. methods: in this study, the terms such as nafld, omega-3 fatty acids, docosahexanoic acid, an...
