Evaluation of the costs of the remediation system using peroxone for the treatment of chlorinated ethenes

Revista Águas Subterrâneas, 2017
The use of Advanced Oxidation Processes for remediation of contaminated areas has become an effective alternative to the destruction of contaminants when applied directly to soil and groundwater or through the treatment systems.

Dehalogenation of Chlorinated Ethenes to Ethene by a Novel Isolate, “Candidatus Dehalogenimonas etheniformans” [PDF]

, 2022
Dehalococcoides mccartyi strains harboring vinyl chloride (VC) reductive dehalogenase (RDase) genes are keystone bacteria for VC detoxification in groundwater aquifers, and bioremediation monitoring regimens focus on D. mccartyi biomarkers. We isolated a

Chlorinated Electron Acceptor Abundance Drives Selection of Dehalococcoides mccartyi (D. mccartyi) Strains in Dechlorinating Enrichment Cultures and Groundwater Environments

Frontiers in Microbiology, 2018
Dehalococcoides mccartyi (D. mccartyi) strains differ primarily from one another by the number and identity of the reductive dehalogenase homologous catalytic subunit A (rdhA) genes within their respective genomes.

Combining microcosm biodegradation and reactive transport modeling to explore the feasibility of ATES-bioremediation approaches

Frontiers in Water
This study presents a process-based model analysis of non-isothermal biodegradation of chlorinated ethenes in batch microcosm setups and field-scale remediation, combining Aquifer Thermal Energy Storage with in situ bioremediation (ATES-ISB).

Methanesulfonic Acid as a Dual‐Role Reagent for Porous Polymer Network Design

Advanced Materials, EarlyView.
The design of porous polymer networks (PPNs) using methanesulfonic acid (MSA) as a dual‐role reagent facilitates the synthesis of robust PPNs for specific applications. It also makes the scale‐up process techno‐economically feasible because MSA functions simultaneously as both a solvent and a catalyst for the reaction.

Temperature-associated effects on methanogenesis and microbial reductive dechlorination of trichloroethene in contaminated aquifer sediments

Frontiers in Water
BackgroundAquifer thermal energy storage (ATES) is a subsurface technology for urban heating and cooling. However, ATES systems may intersect with legacy groundwater contaminants from past anthropogenic activities.

Synthesis of Ti2B2Clx MBenes in Molten Salts From Theoretical and Experimental Perspectives

Advanced Materials, EarlyView.
By integrating a theoretical framework with experiments, Ti2InB2 was selectively etched with ZnCl2 to produce a multilayer (ml) Ti2B2Clx MBene. The In atoms are completely removed, with simultaneous incorporation of chlorine surface terminations. in situ x‐ray diffraction indicates a direct biphasic transformation from Ti2InB2 to ml‐MBene, with no ...

Constraining the fate of chlorinated ethenes in groundwater systems using stable carbon compound specific isotope analysis [PDF]

, 2001
grantor: University of TorontoThe isotopic effects of subsurface processes on the stable carbon isotopic composition, [delta]13C, of chlorinated ethenes were investigated using Compound Specific Isotope Analysis (CSIA).

Enhancing Reaction Kinetics and Structural Control in N‐Carboxyanhydride (NCA) Polypeptide Synthesis by Structurally Tuned Azamacrocyclic Ligands

Angewandte Chemie, EarlyView.
Azamacrocycles provide a tunable platform for rapid N‐carboxyanhydride (NCA) Ring‐Opening Polymerization (ROP). Changing the methylation pattern switches the macrocycle from an external catalyst (N14Me3) to a covalent initiator‐catalyst (IniCat, N14Me1), delivering controlled polypeptide growth under open‐vessel conditions.

A Fully Lithography‐Free Fabrication Strategy for Organic Electrochemical Transistors

Advanced Materials Technologies, EarlyView.
A fully lithography‐free fabrication strategy for organic electrochemical transistors (OECTs) is developed, eliminating the need for photolithography and other cleanroom‐based processes. By combining a laser‐cut polymer mask with a dual‐layer tape process, the proposed strategy enables simple and accessible fabrication, facilitating rapid OECT ...
