Magnetism in purple bronze Li0.9Mo6O17

Dimensional crossover in the purple bronze Li0.9Mo6O17.

Thermal expansion of Li0.9Mo6O17 is a-axis dominated which reduces the separation of the conducting chains at low temperature enhancing the interchain coupling. This destabilizes the Luttinger-liquid fixed point leading to an electronic charge- (or spin-) density wave dominated by Coulomb repulsion, as predicted by theories for Luttinger liquids.

Heterogeneous flavonoid glucosyltransferases in purple derivatives from a controlling element-suppressed bronze mutant in maize.

The Ds(Dissociation)-suppressed bronze mutant bz-m2(DI), which is extremely stable in the absence of the regulatory element Ac (Activator), becomes both somatically and germinally unstable when Ac is present. Instability in the germ line may result in the generation of stable (Ac-nonresponding), colored Bz' derivatives. The characterization of several properties of the Bz-controlled enzyme UDPg...

Probing localization effects in Li0.9Mo6O17 purple bronze: An optical-properties investigation

We report the polarized reflectance and optical conductivity of the quasi-one-dimensional conductor Li0.9Mo6O17 as a function of temperature. The compound displays an unusual ~non-Drude-type! mobile carrier response at low-energy, with partially screened vibrational features along the highly conducting b axis. In addition, we observe Mo d→d transitions near 0.42, 0.57, and 1.3 eV, and an O p→Mo...

Calculated Effects of Disorder on the Mo Core Levels in Purple Bronze Li2Mo12O34

The band structures of ordered and thermally disordered Li2Mo12O34 are calculated by use of ab initio density functional theory (DFT)–Linear Muffin-Tin Method (LMTO) with a focus on the behavior of the Mo 3d -core levels. It is shown that thermal disorder and zero-point motion lead to substantial core level broadening, and the broadening at room temperature is predicted to be sufficiently large...
