Solid-State Deracemization via Temperature Cycles in ...

Feb 09, 2022 Solid-state deracemization via temperature cycles converts a racemic crystal mixture into an enantiopure product by periodic cycling of the temperature in the presence of a racemization catalyst. A continuous counterpart of this conventional batch-operated process is proposed that can be performed in mixed suspension mixed product removal crystallizers …

Separation processes - processdesign

Feb 23, 2016 Every crystallization process is a unique system, so plant evaluation is usually required before complete implementation. Crystallization can be performed in both batch and continuous processes, and design features can control crystal size to an extent (Peters & Timmerhaus, 2003).

Jul 23, 2019 Nuclear reactor fuel contains ceramic pellets of uranium-235 inside of metal rods. Before these fuel rods are used, they are only slightly radioactive and may be handled without special shielding. During the fission process, two things happen to the uranium in the fuel. First, uranium atoms split, creating energy that is used to produce ...

A Process for Capturing CO2 from the Atmosphere - Joule

Jun 07, 2018 An industrial process for large-scale capture of atmospheric CO 2 (DAC) serves two roles. First, as a source of CO 2 for making carbon-neutral hydrocarbon fuels, enabling carbon-free energy to be converted into high-energy-density fuels. Solar fuels, for example, may be produced at high-insolation low-cost locations from DAC-CO 2 and electrolytic hydrogen …

Sodium-Cooled Fast Reactor - an overview | ScienceDirect ...

Malcolm Joyce, in Nuclear Engineering, 2018. 11.7.3 Sodium-Cooled Fast Reactor. The sodium-cooled fast reactor (SFR) Gen IV system is considered to be the design with the greatest maturity for the burning of minor actinides (MA) because fast spectrum neutrons generally have a greater probability for the fission of MA than thermal. As a fast reactor, the …

polymerization | Definition, Classes, & Examples | Britannica

polymerization, any process in which relatively small molecules, called monomers, combine chemically to produce a very large chainlike or network molecule, called a polymer. The monomer molecules may be all alike, or they may represent two, three, or more different compounds. Usually at least 100 monomer molecules must be combined to make a product that has certain …
