A simple model of anisotropic scattering in a quasi two-dimensional metal is studied. Its simplicity allows an analytic calculation of transport properties using the Boltzmann equation and relaxation time approximation. We argue that the c-axis magnetoresistance provides the key test of this model of transport. We compare this model with experiments on overdoped Tl-2201 and find reasonable agre...

We investigated the effects of Fe substitution on ferromagnetic fluctuations in superconducting overdoped and non-superconducting heavily regimes Bi-2201 cuprates by magnetization electrical resistivity measurements. It was found that spin-glass state induced at low temperatures substitution. The Curie constant effective Bohr magneton, estimated from magnetic susceptibility, as well dimensional...

Diastereomeric and geometric analogs of calcipotriol, PRI-2202 and PRI-2205, were synthesized as advanced intermediates from vitamin D C-22 benzothiazoyl sulfones and side-chain aldehydes using our convergent strategy. Calcitriol, calcipotriol (PRI-2201) and tacalcitol (PRI-2191) were used as the reference compounds. Among a series of tested analogs the diastereomeric analog PRI-2202 showed the...

Since the high-Tc cuprates are in essence doped Mott insulators, systematic studies of the evolution of the normal-state properties upon changing the carrier concentration are very useful for elucidating the origin of the peculiar normal state. Bi2Sr2CuO6 (Bi-2201) system is an attractive candidate for such studies, because the carrier concentration can be widely changed by partially replacing ...

Flavor and odor components of foods are often lost during processing, which leads to a final product with poorer quality when compared to fresh made ingredients. It is not a different scenario in orange juice and other beverage industries. Heating processes cause severe physical and chemical losses of the natural characteristic flavour of orange juice. Methods, that use lower heat, present ther...

The Ag/Bi-Sr-Ca-Cu-0 (BSCCO) interface in Ag-clad Bi-2212 tapes was investigated by high-resolution transmission electron microscopy. The interface was found to be well bonded and free of nonsuperconducting second phases. However, a one-half-unit-cell-thick layer of the Bi-2201 phase was observed between the Bi-2212 phase and the Ag-cladding. A very strong texturing of the (00 1) planes of the ...

In two-dimensional (2D) lattices, the electronic levels are unevenly spaced, and the density of states (DOS) displays a logarithmic divergence known as the Van Hove singularity (VHS). This is the case in particular for the layered cuprate superconductors. The scanning tunnelling microscope (STM) probes the DOS, and is therefore the ideal tool to observe the VHS. No STM study of cuprate supercon...
