Special Issue in Honor of Michael F. Hochella, Jr.

This VSI honors Prof. Michael (Mike) F. Hochella, Jr. for his enormous contributions to the fields of low-temperature geochemistry, mineral/water interface chemistry, biogeochemistry, environmental chemistry, and the relatively new field of nanogeoscience. As a result of his groundbreaking research, mentorship and service in the field of geochemistry, Mike was awarded the 2021 ACS Geochemistry Division Medal. Twenty articles in this VSI cover topics ranging from Mineral/Water Interface Chemistry and Mineral/Organic Matter Nanoparticles to Organic Matter/Soil Chemistry and Microbial Geochemistry Studies. They highlight the importance of nanogeoscience, mineral/aqueous solution interface chemistry, biogeochemistry, and organic matter/soil chemistry in understanding the Earth System.
