WebThe refinement of the NH 4 (1) and NH 4 (2) orientational positions in phase II was carried out by the x-ray and neutron single-crystal diffraction study. The analysis of difference Fourier maps of electron charge density and nuclear density suggested the possibility of disordering of NH 4 (2) ammonium ions. WebAqueous zinc-ion batteries (ZIBs) play a vital role in large-scale energy storage for smart grids due to their environmental friendliness, safety, and low cost. Unfortunately, the application of ZIBs has been challenged by the relatively low capacity of cathode materials, especially at higher rates, which originates from the sluggish diffusion of Zn ions. Herein, … WebOct 1, 1996 · Single crystals of the trihydrated praseodymium cyclotriphosphate PrP{sub 3}O{sub 9}.3H{sub 2}O were grown for the first time, using a classical method of aqueous chemistry and characterized by single crystal X-ray diffraction. PrP{sub 3}O{sub 9}.3H{sub 2}O is isostructural with LnP{sub 3}O{sub 9}.3H{sub 2}O (Ln=La, Ce and Nd). ata agenda
