The disposal of fish scales as waste presents an environmental challenge and untapped opportunity for resource recovery. In this study, hydroxyapatite (HAp) was extracted from European seabass (Dicentrarchus labrax) to explore how air exposure during calcination affects its optical surface properties. HAp powders were prepared under two distinct conditions: fully exposed (producing white powder) partially shielded (resulting in gray powder). Rietveld refinement X-ray powder diffraction...
We unveil a clear link between cation structural-disorder in the tetrahedral sites of fcc-structured superconducting A 3 C 60 fullerides and their electronic properties as manifested by reduction transition temperature, T c .
The ternary fulleride, Rb[Formula: see text]Cs[Formula: text]C[Formula: text], is the most expanded member of family face-centered cubic (fcc) structured superconducting fullerides ever accessed with superconductivity surviving at ambient pressure closest to Mott insulator boundary. Here, we study evolution its structural and electronic properties temperature. At temperature, text] lies in Mott–Jahn–Teller (MJT) insulating part phase diagram. High-resolution synchrotron X-ray diffraction...
Cs4O6 is a mixed-valence molecular oxide with cubic structure, comprising valency-delocalized O24/3– units and properties highly sensitive to cooling protocols. Here we use neutron powder diffraction authenticate that, while upon deep quenching the phase kinetically arrested down cryogenic temperatures, ultraslow results in an incomplete structural transition contracted tetragonal phase. Two dioxygen anions 1:2 ratio are identified, providing evidence that accompanied by charge orbital order...
Cs4O6 adopts two distinct crystal structures at ambient pressure. At temperatures below ∼200 K, its ground state structure is tetragonal, incorporating symmetry-distinct dioxygen anions, diamagnetic peroxide, O22–, and paramagnetic superoxide, O2–, units in a 1:2 ratio, consistent with the presence of charge orbital order. high temperatures, cubic, comprising symmetry-equivalent an average oxidation −4/3, adoption charge-disordered state. The pressure dependence solid 300 K 13.4 was followed...
The un-doped and Co-doped SnO2 samples having high crystallinity were successfully prepared. effects of Co content on the structural, thermal morphological properties investigated. Changes in crystallite size unit cell parameters detected with adding Co. phase composition did not alter addition Both X-ray diffraction Fourier transform infrared results confirmed formation structure for each sample. stability as-produced from room temperature to 900 °C was observed. morphology affected by...
The present study focuses on the structural changes in ZnO powder induced by doping of a rare earth metal Y. For this aim, we synthesized four samples with different Y-content using combustion reaction method. X-ray diffraction (XRPD) technique and scanning electron microscopy (SEM) results confirm that as-investigated parameters morphology structure were affected directly concentration Y dopant. each Y-doped sample, randomly-oriented pyramidal formation minority phase Y2O3 observed. A...
The existence of cation-vacancy sites in fullerides might lead to long-range ordering and generate a new vacancy-ordered superstructure. purpose this work is search whether or not vacant tetrahedral sites, namely superstructure emerges nonstoichiometric K 1.5 Ba 0.25 CsC 60 fulleride. Therefore, with synthesized using precursor method avoid inadequate stoichiometry control formation impurity phases within the target composition. For purpose, first, phase-pure 6 C , Cs precursors are...
