Acting as a co-factor for hundreds of enzymes, zinc (Zn) is an essential trace metal required for organismal success across all phyla. When aquatic organisms such as fish are Zn deficient, growth, metabolism, and health are all negatively impacted. However, Zn in excess may also impair overall...

Zinc in Precambrian iron formations: The record, partitioning, diagenetic effects and implications for eukaryotic metallome evolution
DownloadFall 2013
Zinc is amongst the most important trace elements for eukaryotes. Previous work has suggested it to have been at biolimiting concentrations for much of the Precambrian, thereby limiting eukaryotic evolution. Yet, the iron formation (IF) record, a critical proxy for paleomarine conditions, has...

Zooarchaeological Analysis of Avian Skeletal material in Neolithic and Early Bronze Age Mortuary Contexts, Cis-Baikal, Siberia
DownloadSpring 2013
During the Neolithic and Early Bronze Age in Cis-Baikal, Siberia, human groups inhabiting the region interred their deceased with a variety of objects, including modified and unmodified avian skeletal elements. Archaeological excavation of graves in the Shamanka II, Lokomotiv, and Ust’-Ida...

ZVI-loaded Biochar Composite for Effective Peroxymonosulfate Activation: Application in the Removal of Naphthenic Acids from Real Oil Sands Process Water
DownloadSpring 2024
Vasquez Aldana, Adriana Marcela
Oil Sands Process Water (OSPW) is a byproduct generated during the extraction of bitumen from oil sands deposits in Northern Alberta, Canada. This matrix presents a critical environmental and industrial challenge due to its toxic nature, primarily associated with its complex mixture of...

Zwitterionic Surfactant for EOR in Tight Carbonate Reservoir: Physico-Chemical Interaction and Microfluidic Study
DownloadFall 2019
Recently, during surfactant aided recovery processes for unconventional reservoirs, carboxybetaine based zwitterionic surfactants (CnDmCB) have attracted attention due to their good tolerance to high saline produced water, remarkable water solubility, and ultra-low interfacial tension (IFT) at...
