The formation pathway of Li4SiO4 involves Li2SiO3 as an intermediate. Carbonation of Li4SiO4 under dynamical conditions retards the double shell formation, improving CO2 capture capacity.

Spotty diffraction rings arise when the size distribution of crystallites illuminated by the incident beam includes crystallites that are large compared with the size of the beam. In this article, several statistical measures are used in conjunction to quantify spottiness and relate it to a crystallite size distribution: the number of peaks, the normalized root mean square intensity variation and the fractal dimension. These are demonstrated by way of example using synchrotron X-ray diffraction patterns collected duringin situcorrosion of mild steel in carbon dioxide-saturated aqueous brine.

Porous Framework

Presented here is a water-stable MOF material [ In (5- AIPA )2] ⋅ Me 2 NH 2(1; 5-AIPA = 5-Aminoisophthalic acid) built from the connecting of tetrahedral building units [ In ( COO )4]-. The sql net of compound 1 exhibits preferable chemical and thermal stability confirmed by thermal gravimetric analyses (TGA) and powder X-ray diffraction pattern (PXRD) measurements. The activated empty phase of 1a, as a good candidate material for CO 2 capture, shows a CO 2 uptake of 56.6 cm3/g and CH 4/ CO 2 selectivity in excess of 16.4. Remarkably, based on the cation exchange mechanism, 1a has excellent MB affinity and can adsorb MB over MO from water in two hours. The results further support the idea that the ionic MOFs can find more applications in the separation of ionic dyes for the purifying of dye wastewater.

The Fe2.75Mn0.25O4 nanoparticles were successfully synthesized by using the coprecipitation method, while the Fe2.75Mn0.25O4@PANI materials were successfully fabricated by using the in situ polymerization method. This research aimed to investigate the magnetic properties and nanostructure of the Fe2.75Mn0.25O4 nanoparticles and Fe2.75Mn0.25O4@PANI materials. Some characterizations of the samples were successfully carried out by using X-Ray Diffraction (XRD) instruments, Fourier Transform Infrared (FTIR), and Vibrating Sample Magnetometer (VSM) each of which was conducted to characterize the crystal structure, functional groups, morphology, and the magnetic properties of the materials. The XRD analysis results showed that the Fe2.75Mn0.25O4@PANI materials had a crystal size of 8.09 nm. Meanwhile, the FTIR spectrum represented vibrations due to the atomic bonds that made up the Fe2.75Mn0.25O4@PANI materials. Furthermore, the hysteresis curve from the VSM characterization results showed that the Fe2.75Mn0.25O4@PANI material saturation magnetization value was around 2.85 emus/g. From those characterization results, the Fe2.75Mn0.25O4@PANI materials are very potential to be applied as magnetic ink

Carbonate Anion

Spontaneous atmospheric CO2 capture as carbonate anion occurred in the synthesis of a trinuclear Cd(II) complex with tris(2-aminoethyl)amine ligand. In reaction two types of compounds were obtained and structurally characterized by X-ray diffraction on a single crystal: initially [{Cd(tren)}3(tren)](ClO4)6·2H2O (1) and subsequently [{Cd(tren)}3(tren)][{Cd(tren)}3(µ3-ηCO3)](ClO4)10 (2). The carbonate anion replaces partially the bridging tren molecule and coordinates in a µ3 fashion. The luminescent properties of the compounds were investigated.
