Assessing Distinctive Physiochemical Properties of Geopolymers, Their Green Development and Utilization in Wastewater Treatment

Water and Environment Journal, EarlyView.
This review examines the physicochemical properties of geopolymers, focusing on the effects of calcium content, heavy metal impurities and acid activation. It distinguishes geopolymers from other alkali‐activated materials based on structure and synthesis precursors. Their use as water treatment adsorbents is compared with ceramic filters, highlighting

Using Variable Chlorophyll-a Fluorescence to Assess the Impact of Ocean Alkalinity Enhancement on the Photochemical Efficiency of Phytoplankton

Ocean Alkalinity Enhancement (OAE) is a potential carbon dioxide removal strategy to mitigate climate change by enhancing oceanic carbon uptake. This thesis contributes to the biological risk assessment of OAE by examining its effects on phytoplankton ...

Interactions between ocean alkalinity enhancement and phytoplankton in an Earth system model

Biogeosciences
Abstract. The functioning and efficiency of ocean alkalinity enhancement (OAE) as a CO2 removal strategy is well investigated in model studies, but risks for the ecosystem are presently not considered in models. Our study examines OAE–phytoplankton feedbacks in an Earth system model by adding carbonate system dependencies to the phytoplankton growth ...

Ocean Alkalinity Enhancement in Deep Water Formation Regions Under Low and High Emission Pathways

Earth's Future
Ocean Alkalinity Enhancement (OAE) is an ocean‐based Carbon Dioxide Removal (CDR) method to mitigate climate change. Studies to characterize regional differences in OAE efficiencies and biogeochemical effects are still sparse.
