The discovery of the photchemical reduction of water by europium(II) ion is reported. By use of a chemical actinometer for determining light intensities and a Gouy balance for following the change in magnetic susceptibility overall quantum yields were determined to be about 0.2 for solutions 0.5 m. in HCl and 0.15 m. in EuCl2.

The chemistry of the Hispanic-American amalgamation process

Journal of the Chemical Society, Dalton Transactions, 1999
The chemistry of the Hispanic-American amalgamation or patio process for the extraction of silver has been studied through a laboratory model in which a suspension of silver sulfide in concentrated sodium chloride solution reacts with copper(II) chloride before being treated with mercury. Approximately 90% of the silver was extracted and separated as a

Amalgamation of Synthetic Biology and Chemistry for High-Throughput Nonconventional Synthesis of the Antimalarial Drug Artemisinin

Organic Process Research & Development, 2017
The development of a cost-effective process for the production of artemisinin, the precursor of all artemisinin-derived drugs, the first-line treatment for malaria, has been a long-pursued endeavor. The breakthrough achievement of coaxing genetically engineered yeast to express Artemisia annua genes for the commercial production of artemisinic acid, an
