Innovative techniques for the production of energetic radicals for lunar materials processing including photogeneration via concentrated solar energy [PDF]

open access: yes
A technique for photo generation of radicals is discussed that can be used in the recovery of oxygen and metals from extraterrestrial resources. The concept behind this work was to examine methods whereby radicals can be generated and used in the ...

Coal desulfurization by low temperature chlorinolysis, phase 3 [PDF]

open access: yes
Laboratory scale, bench scale batch reactor, and minipilot plant tests were conducted on 22 bituminous, subbituminous, and lignite coals. Chemical pretreatment and post treatment of coals relative to the chlorination were tried as a means of enhancing ...

Detection and Treatment Methods for Perfluorinated Compounds in Wastewater Treatment Plants

open access: yesApplied Sciences, 2019
We surveyed the variation in perfluorinated compound (PFC) concentrations entering urban wastewater treatment plants and then designed an optimal PFCs treatment method based on a pilot test. The PFCs influent concentration was found to be affected by the

Organocatalytic asymmetric fluorination of α-chloroaldehydes involving kinetic resolution

open access: yesBeilstein Journal of Organic Chemistry, 2014
In a previous study it was shown that the enantioselective α-fluorination of racemic α-chloroaldehydes with a chiral organocatalyst yielded the corresponding α-chloro-α-fluoroaldehydes with high enantioselectivity.
