Sulfide perovskites (ABX3) are under increasing investigation for use in photovoltaic,
optoelectronic, dielectric, and thermoelectric devices due to their favorable band gaps …

Luminescence thermometry exploiting luminescence kinetics as a thermometric parameter
is regarded as one of the most reliable temperature readout techniques. Transition metal …

The nonlinear dynamics of a one-dimensional molecular crystal in the form of a chain of
planar coronene molecules is analyzed. Using molecular dynamics, it is shown that a chain …

Abstract The Mott insulator Ca 2 RuO 4 is a paradigmatic example among transition metal
oxides, where the interplay of charge, spin, orbital, and lattice degrees of freedom leads to …

Most materials in Nature expand when heated, and very limited materials show the opposite
behavior, ie, negative thermal expansion (NTE). Here, we observed that NTE is associated …

The fullerene family, whose most popular members are the spherical C 60 and C 70
molecules, has recently added a new member, the cube-shaped carbon molecule C 8 called …

The phenomenon of negative thermal expansion (NTE) deals with the increase of the lattice
parameters and the volume of the unit cell when the material is thermally cooled. The NTE is …

A rotobreather in a lattice of coupled particles with rotational degrees of freedom is a
dynamical regime when one particle rotates and the other particles vibrate with amplitudes …

The analysis of Raman and Infrared (IR) phonons in monolayered tetragonal Ca 2 TO 4 (T=
Si, Ti, Mn, Ge) compounds, which exhibit D 17 4 h symmetry and belong to the I4/mmm …

This study examines the effect of barium titanate addition at 3 different rates (BaTiO3; 1wt%,
3 wt% and 5 wt%) on the mechanical performance, in vitro bioactivity and morphological …
