The last 20 years have seen a surge in scientific activity and promising results in the study of aging and longevity. Many researchers have focused on telomeres, which are composed of a series of TTAGGG repeat nucleotide sequences at the ends of each

We report optical measurements of ${\mathrm{NdNiO}}_{3}$ that undergo a phase transition from a paramagnetic metal to an antiferromagnetic insulator at 200 K (=${\mathit{T}}_{\mathit{c}}$). The opening of a charge gap is observed in the optical condu

New substituted compounds of composition *Bi2-xPbxSrNb2O9-x/2 (O≤x≤2) have been isolated as single phases, keeping the basic structure of the Aurivillius oxides. These materials were characterized by X-ray powder diffraction methods, at different

A unified interpretation is given for the infrared and optical spectra of many TCNQ compounds which exhibit a wide variety of physical properties. Inter- and intra-molecular transitions are distinguished by polarization measurements on single crystal

Taking as the starting material the Bi 2 SrNb 2 O 9 Aurivillius oxide, it has been demonstrated that the Bi 3+ ions in the (Bi 2 O 2 ) 2+ layer can be replaced by other p-cations possessing a stereochemical active lone pair of electrons. In this way,

We have investigated the pressure dependence (up to 20 kbar) of the metal-insulator (MI) transition displayed by the orthorhombic perovskites R${\mathrm{NiO}}_{3}$ (R=Nd, Pr, and ${\mathrm{Nd}}_{0.7}$${\mathrm{La}}_{0.3}$) by means of electrical resi

In the R${\mathrm{NiO}}_{3}$ series (R=La,Pr,Nd,Sm), the metal-insulator (M-I) transition temperature rises systematically as the size of the rare earth decreases and as the subsequent distortion from the ideal cubic perovskite increases. For R=La th
