“…Thirdly, the number of charged (Na + ions) carriers in A‐CP is greater than that in alkali cellulose. Compared to other sodium‐based materials such as Na 2 Co 2 (MoO 4 ) 3 ( E a = 1.2 eV), Na 2 CoP 1.5 As 0.5 O 7 ( E a = 0.56 eV), 32 Na 2 CuP 1.5 As 0.5 O 7 ( E a = 0.60 eV), 33 Na 7 Li 0.8 K 0.2 Co 5 (As 3 O 10 ) 2 (As 2 O 7 ) 2 ( E a = 0.83 eV) 34 and Na 1.14 K 0.86 CoP 2 O 7 ( E a = 1.34 eV) 35 and other monovalent ion materials such as TlFeHP 3 O 10 ( E a = 0.664 eV) 36 and Ag 3.68 Co 2 (P 2 O 7 ) 2 ( E a = 1.70 eV), 8 A‐CP shows a fast electric conductivity at low temperature in the range 393–459 K with values of E a = 0.73 eV; σ 393K = 3.01 × 10 −7 S cm −1 32–34 . A‐CP can be investigated in future work as a cathode for rechargeable batteries which is an area of intense activity in the field of manufacturing batteries based on degradable polymers.…”

In this study, alkali cellulose‐6‐phosphate (A‐CP) was prepared by the treatment of cellulose‐6‐phosphate (CP) with an aqueous solution of sodium hydroxide. X‐ray diffraction and Fourier transform infrared, 13C NMR, 31P NMR and 23Na NMR spectroscopies were used to characterize the studied polymers. CP and A‐CP crystallize in the monoclinic system of the P21 space group (cellulose Iβ). CP and A‐CP, with relative densities of 70% and 77%, respectively, were shaped into cylindrical pellets by uniaxial pressing and sintering at 423 K of A‐CP. Electrical conductivity measurements of CP and A‐CP were carried out using complex impedance spectroscopy between 298 and 433 K in the frequency range 5 Hz to 13 MHz. The influence of aqueous NaOH on the structure, thermal stability and electrical conductivity of cellulose phosphate was observed. In contrast to CP, A‐CP was stable up to temperatures exceeding 433 K and showed fast ionic conductivity σ393K = 2.03 × 10−6 S cm−1 with an activation energy of 0.73 eV. © 2021 Society of Chemical Industry

“…The number of acting parameters is relatively few but difficult to control. This method is commonly used for the synthesis of the single crystals and polycrystalline powders of phosphates and arsenates of transition metals and monovalent cations [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17].…”

The synthesis of single crystal is an area of intense activity in the materials science. The obtaining of the single crystal with sufficient dimension for X-ray diffraction depends on several factors including the chemical composition, crystal structure of the reagents, and physical parameters (temperature and pressure). In this context, this chapter is dedicated to the description of the most common synthesis methods of single crystal in the solid-state chemistry: solid-state method, hydrothermal, and slow evaporation at room temperature. Same other materials can be obtained at high pressure. There are also some physical techniques to grow single crystal, each technique is specific for specific materials.

In this chapter, the correlation between structure and electrical properties of Na2MP1.5As0.5O7 (MII = Co and Cu) are treated. The structural study shows that the cobalt and copper isotype materials can be crystallized in the tetragonal and monoclinic systems, respectively. The electrical study using impedance spectroscopy technique showed that these mixed diphosphate diarsenates are fast electrical conductors; however, the cobalt material exhibited more conductive property than the copper compound. In addition, the powder perovskite manganites La0.7M0.2M’0.1MnO3 (M = Sr, Ba and M’ = Na, Ag and K) have been prepared using the conventional solid-state reaction. The structural, magnetic, and magnetocaloric properties of these perovskite manganites compounds were studied extensively by means of X-ray powder diffraction (XRD) and magnetic measurements. These samples were crystallized in the distorted rhombohedral system with R3c space group. The variation of magnetization (M) vs. temperature (T) reveals that all compounds exhibit a second-order ferromagnetic to paramagnetic phase transition in the vicinity of the Curie temperature (TC). A maximum magnetic entropy change, ΔSMMax, of 4.07 J kg−1 K−1 around 345 K was obtained in La0.7Sr0.2Na0.1MnO3 sample upon a magnetic field change of 5 T. The ΔSMMax values of La0.7Ba0.2M’0.1MnO3 are smaller in magnitude compared to La0.7Sr0.2M’0.1MnO3 samples and occur at lower temperatures.
