Investigation on the influence of chelating agent on carbon sequestration in cement-based materials

Case Studies in Construction Materials
The incorporation of a chelating agent significantly enhances the mineralization reaction in cement-based materials during carbonation curing, thereby increasing CO₂ sequestration efficiency and contributing to a measurable reduction in net CO₂ emissions.

A New Multichelating Acid System for High-Temperature Sandstone Reservoirs

Journal of Chemistry, 2015
Sandstone reservoir acidizing is a complex and heterogeneous acid-rock reaction process. If improper acid treatment is implemented, further damage can be induced instead of removing the initial plug, particularly in high-temperature sandstone reservoirs.

The iron chelating agent, deferoxamine detoxifies Fe(Salen)-induced cytotoxicity

Journal of Pharmacological Sciences, 2017
Iron-salen, i.e., μ-oxo-N,N′-bis(salicylidene)ethylenediamine iron (Fe(Salen)) was a recently identified as a new anti-cancer compound with intrinsic magnetic properties. Chelation therapy has been widely used in management of metallic poisoning, because

Evaluation of Barium Sulfate (Barite) Solubility Using Different Chelating Agents at a High Temperature [PDF]

Journal of Petroleum Science and Technology, 2017
Barium sulfate (barite) is one of the widely used weighting materials in the preparation of drilling fluid for deep oil and gas wells. Barite is not soluble in the regular solvents; such as, hydrochloric acid (HCl) and other acids.

Recycling iron from pickling sludge to activate peroxydisulfate for the degradation of phenol

Water Science and Technology, 2022
In this work, iron was recovered from a kind of iron-rich pickling sludge by an acid leaching process, and the recycled iron was used as a catalyst to activate peroxydisulfate (PS) for the degradation of phenol.

Reconstructing enzyme evolution by protein engineering

FEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

The therapeutic opportunities and pitfalls of using iron ion chelators to treat neurodegenerative diseases

FEBS Letters, EarlyView.
Although too much iron in the brain promotes neurodegeneration, iron ion chelators have had mixed effects in clinical trials. This review explains why; some chelators do not render the iron redox‐inactive (e.g., L1) whereas others do (e.g., desferrioxamine).
