Chemical Recycling as a Tool for Enabling a Second Life for Polyesters

SusMat, EarlyView.
This review presents the elucidation of the life cycle of main polyesters, detailing end‐of‐life methods, with focus of solvolysis technologies, then an analysis of LCA and TEA on literature data, an original data analytic, and, finally, a current industrial mapping of the main processes with a critical perspective on the plastic life‐cycle ecosystem ...

XENON POISONING IN MOLTEN SALT REACTORS

, 1961
The xenon poison fraction in a 1000-mwe molten salt breeder reactor power plant (MSBR) was calculated as a function of sparging cycle-time and the rate of diffusion of xenon into graphitic structure in contact with the fuel salt. lt was found that the xenon poison fraction can be held to 0.005 neutrons per neutron absorbed in fuel atoms by passing the ...

Photocatalytic and Biotechnological Strategies for Remediation of Persistent Organic Pollutants: Mechanisms, Toxicity, and Antimicrobial Perspectives

Environmental Toxicology, EarlyView.
ABSTRACT Persistent organic pollutants (POPs) pose significant ecological and human health risks due to their persistence, bioaccumulation, toxicity, and global distribution. Conventional remediation methods are often inadequate for achieving complete mineralization, demonstrating the need for advanced and substantial approaches.

Synthesis of Ethyl Methyl Carbonate: Past, Present, and Future

Advanced Synthesis &Catalysis, Volume 368, Issue 15, 1 August 2026.
Ethyl methyl carbonate (EMC) is the simplest asymmetric organic carbonate, with properties between dimethyl (DMC) and diethyl (DEC) carbonate, considered a unique green liquid organic compound for lithium batteries (electrolyte) and gasoline blending (octane enhancer additive), among other uses. In accordance, the chemical production of EMC is expected
