This review is devoted to the discussion of hadron properties in the nuclear medium and its relation to the partial restoration of chiral symmetry. Special attention is given to disentangle inmedium effects due to conventional many-body interactions from those due to the change of the chiral condensate. In particular, we shall discuss medium effects on the Goldstone bosons (pion, kaon and eta),...

From resonant Raman scattering on isolated nanotubes we obtained the optical transition energies, the radial breathing mode frequency, and the Raman intensity of both metallic and semiconducting tubes. We unambiguously assigned the chiral index (n(1),n(2)) of approximately 50 nanotubes based solely on a third-neighbor tight-binding Kataura plot and find omega(RBM)=(214.4+/-2) cm(-1) nm/d+(18.7+...

We consider relativistic fermionic systems in lattice regularization out of equilibrium. The chiral magnetic conductivity ${\ensuremath{\sigma}}_{\mathrm{CME}}$ is calculated a spatially infinite system for the case when chemical potential depends on time, while initially was thermal equilibrium at small but nonzero temperature. find that frequency-dependent ${\ensuremath{\sigma}}_{\mathrm{CME}...

In the presence of fluid helicity $\boldsymbol{v} \cdot \boldsymbol{\omega}$, magnetic field induces an electric current form $\boldsymbol{j} = C_{\rm HME} (\boldsymbol{v} \boldsymbol{\omega}) \boldsymbol{B}$. This is helical effect (HME). We show that for massless Dirac fermions with charge $e=1$, transport coefficient $C_{\rm HME}$ fixed by chiral anomaly $C=1/(2\pi^2)$ as C/2$ independently ...

an efficient one-pot three-component procedure for the synthesis of new chiral spiro-oxindolopyrrolizidines with highly regio-, diastereo-, and enantioselective from 1,3-dipolar cycloaddition of azomethine ylides and optically pure active cinamoyl oxazolidinone are described. the process occurs at room temperature in aqueous ethanol as green solvent and in the absence of any bidentate chelating...

in recent years there has been considerable interest in the synthesis and separation of enantiomers of organic compounds especially because of their importance in the biochemistry and pharmaceutical industry. high-performance liquid chromatography is a very useful method for the direct separation of enantiomers. however, about 30−40 years ago, commercially available chiral stationary phases wer...

one of the problems encountered in ce separations of basic compounds is the adsorption of analytes onto the negatively charged capillary wall which could lead to poor repeatability of migration time and peak area. additionally, separation of enantiomers of chiral of basic drugs is commonly carried out in low ph buffer which contributes to strong ionic interaction of the cationic drug ions with ...
