X-ray scattering measurements are performed in order to verify % that the mechanism leading to the DC electric field induced $C_{2v}^{19} \to C_{2v}^{\neq 19}$ phase transition in KDP crystal at 119 K is the changing of the local sites symmetries of

Pressure-dependent Raman scattering studies in the range 0.0 -- 32 kbar were carried out in L-alanine in order to investigate its external mode phonon spectra in relation to the phase transitions in the crystal. A careful analysis of the spectra show

This work reports on the systematic high pressure Raman studies in the PbZr$_{1-x}$Ti$_x$O$_3$ ($0.02 \leq x \leq 0.14$) ceramics performed at room temperature. The pressure dependence of the Raman spectra reveals the stable phases of the material un

We have investigated the behavior of the PbZr(0.94}Ti(0.06)O3 Raman spectra as a function of Hydrostatic pressures. The new structural phases were identified based on previous works performed in PZT system with different Ti concentrations at room- an

Bacterial cellulose nanocrystals (BCNCs) have hydrophilic surfaces due to hydroxyl groups but are water-insoluble. The carboxymethylation improves the solubility of cellulose in polar media through the insertion of carboxymethyl groups. This study ai
