چکیده
Lead-free Sn(II) based, CsSn2Br5, perovskite nanocubes were synthesized using a modified hot-injection method by tuning the injection temperature and reaction conditions. The formation of Sn(IV) Cs2SnBr6, nanocrystals (PNCs) from CsSn2Br5 was observed. X-ray diffraction measurements revealed that oxygen or water molecules in air gradually react with to form Cs2SnBr6 NCs. stability NCs monitored time-dependent absorption measurements. Both degrade, however appears largely has been improved dispersing degassed anhydrous solvent.

A facile co-precipitation method for the synthesis of well-dispersed NdFeO3 nanocrystals is developed in the presence of octanoic acid as surfactant. Co-precipitation can produce fine, high-purity, stoichiometric particles of single and multicomponent metal oxides. The product is characterized by Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), scanning electron microsc...
متن کاملsimulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...

15 صفحه اولEncapsulation of Perovskite Nanocrystals into Macroscale Polymer Matrices: Enhanced Stability and Polarization.
Lead halide perovskites hold promise for photonic devices, due to their superior optoelectronic properties. However, their use is limited by poor stability and toxicity. We demonstrate enhanced water and light stability of high-surface-area colloidal perovskite nanocrystals by encapsulation of colloidal CsPbBr3 quantum dots into matched hydrophobic macroscale polymeric matrices. This is achieve...
