“…As the smoothness of the crystal surface increases with the rise of the surface entropy factor, the growth rate of the crystal decreases and the crystal growth at this time belongs to helical dislocation-type growth [44][45][46]. Conversely, when the surface entropy factor is low, the growth rate of the crystal surface is faster when the crystal exhibits reduced surface smoothness and when the growth satisfies the continuum-type growth mode [47,48]. However, if we follow Equation ( 9), calculating the surface entropy factor is difficult to achieve, so we need to simplify this equation.…”

Effects of Solubilizer and Magnetic Field during Crystallization Induction of Ammonium Bicarbonate in New Ammonia-Based Carbon Capture Process

As a chemical absorption method, the new ammonia carbon capture technology can capture CO2. Adding ethanol to ammonia can reduce the escape of ammonia to a certain extent and increase the absorption rate of CO2. The dissolution and crystallization of ethanol can realize the crystallization of ammonium bicarbonate and generate solid products. The induction of the crystallization process is influenced by many parameters, such as solution temperature, supersaturation, and solvating precipitant content. The basic nucleation theory is related to the critical size of nucleation. Accurate measurement of the induction period and investigating relevant factors can help to assess the nucleation kinetics. The effects of solubilizer content, temperature, and magnetic field on the induction period of the crystallization process of ammonium bicarbonate in the ethanol–H2O binary solvent mixture and determining the growth mechanism of the crystal surface by solid–liquid surface tension and surface entropy factor are investigated. The results indicate that under the same conditions of mixed solution temperature, the crystallization induction period becomes significantly longer, the solid–liquid surface tension increases, and the nucleation barrier becomes more significant and less likely to form nuclei as the content of solvating precipitants in the components increases. At the same solubilizer content, there is an inverse relationship between the solution temperature and the induction period, and the solid–liquid surface tension decreases. The magnetic field can significantly reduce the induction period of the solvate crystallization process. This gap tends to decrease with an increase in supersaturation; the shortening reduces from 96.9% to 84.0%. This decreasing trend becomes more and more evident with the rise of solvent content in the solution. The variation of surface entropy factor under the present experimental conditions ranges from 0.752 to 1.499. The growth mode of ammonium bicarbonate in the ethanol–H2O binary solvent mixture can be judged by the surface entropy factor as continuous growth.

In this study, both the internal and external stability of a p‐i‐n methylammonium lead iodide perovskite solar cell (PSC) is improved. Polystyrene (PS) is introduced into the perovskite layer to form a cross‐linked polymer‐perovskite network, which enhances the nucleation and growth of the perovskite grains. Moreover, for the first time, 60‐nm‐thick ZnO/AlOx nanolaminate thin‐film encapsulation (TFE) is deposited directly on the PSC using an atmospheric‐pressure spatial atomic layer deposition (AP‐SALD) system operated in atmospheric‐pressure spatial chemical vapor deposition (AP‐SCVD) mode. The rapid nature of AP‐SCVD enables encapsulation of the PSCs in open air at 130°C without damaging the perovskite. The PS additive improves the performance and internal stability of the PSCs by reducing ion migration. Both the PS additive and the ZnO/AlOx nanolaminate TFEs improve the external stability under standard test conditions (dark, 65°C, 85% relative humidity) by preventing water ingress. The number and thickness of the ZnO/AlOx nanolaminate layers is optimized, resulting in a water‐vapor transmission rate as low as 5.1×10‐5 g/m2/day at 65°C and 85% relative humidity. A fourteen‐fold increase in PSC lifetime is demonstrated; notably, this is achieved using polystyrene, a commodity‐scale polymer, and AP‐SCVD, a scalable, open‐air encapsulation method.This article is protected by copyright.
