Coatings 2021, 11, 854 9 of 13 tion were prolonged. In addition, as the reaction temperature increases, the equilibrium time is significantly shortened and the yield becomes larger. However, the particle size of the product remains unchanged under normal pressure. Taken together, the cooling crystallization method proposed in this article can make it possible to prepare MIL-121 at atmospheric pressure with reaction time of several hours. Considering the comprehensive factors such as product yield, the reaction time can be shortened to 5–10 h when the reaction temperature was 80 ◦C. When the reaction temperature approached 100 ◦C, the preparation time can be shortened to be less than 5 h. This method greatly decreased the preparation cost and time, and the preparation conditions were relatively mild. MIL-121 with uniform particle size distribution can be obtained under ambient pressure and low temperature conditions (Table S3, Supplementary Materials, the preparation method and preparation time of common aluminum-based MOF.) The morphology of the products collected in the cooling crystallization of MIL-121 promoted by the NaOH and the morphology of the products obtained in the large-scale experiment were both characterized by SEM as shown in Figure 6. The morphology of MIL- 121 obtained by cooling crystallization was consistent with the morphology of the products collected by the hydrothermal method. They were both regular polyhedron. The difference was that the products obtained by cooling crystallization were attached with smaller particles of MIL-121. The particle size distribution diagram of large-scale experimental product was shown in Figure S4d (Supplementary Materials). The particle size distribution is more uniform than that of hydrothermal synthesis products. The particle size of the cooling crystallization product was smaller than that of the hydrothermal method at the same temperature, and the median diameter D50 is 1.57 μm. The stability of the product was confirmed by TG. The derivative in Figure 7 demonstrated that the sample decomposed step-by-step as the temperature increases. The first stage is mainly the removal of the solvent ethanol and deionized water used for cleaning, and the subsequent stage is the decomposition of the carboxyl group and the framework. The dehydration temperature is 246 ◦C, and the initial decomposition temperature is about 386 ◦C. Compared with the thermal stability data of the hydrothermal method MIL-121-80 ◦C, MIL-121-90 ◦C, and MIL-121-100 ◦C products (Table S4, Supplementary Materials), the thermal stability of the product produced by cooling crystallization is better.

On the basis of the 100 mL scale cooling crystallization experiment, a 250 mL crys- tallizer was used for scale-up experiments.

Product and Development Focus for Infinity Turbine
ORC Waste Heat Turbine and ORC System Build Plans: All turbine plans are $10,000 each. This allows you to build a system and then consider licensing for production after you have completed and tested a unit.Redox Flow Battery Technology: With the advent of the new USA tax credits for producing and selling batteries ($35/kW) we are focussing on a simple flow battery using shipping containers as the modular electrolyte storage units with tax credits up to $140,000 per system. Our main focus is on the salt battery. This battery can be used for both thermal and electrical storage applications. We call it the Cogeneration Battery or Cogen Battery. One project is converting salt (brine) based water conditioners to simultaneously produce power. In addition, there are many opportunities to extract Lithium from brine (salt lakes, groundwater, and producer water).Salt water or brine are huge sources for lithium. Most of the worlds lithium is acquired from a brine source. It's even in seawater in a low concentration. Brine is also a byproduct of huge powerplants, which can now use that as an electrolyte and a huge flow battery (which allows storage at the source).We welcome any business and equipment inquiries, as well as licensing our turbines for manufacturing.CONTACT TEL: 608-238-6001 Email: greg@infinityturbine.com (Standard Web Page)
