Decision Theory and Proof Standards for Future Crimes: Possible Uses and Open Questions

open access: yesBehavioral Sciences &the Law, EarlyView.
ABSTRACT What should be the proof standard for applying preventive criminal sanctions based on an establishment of risk of reoffending? This is an open question in legal systems around the world. Various authors suggest that we can answer it by using decision theory. This approach conceptualises the proof standard as a probabilistic threshold. A person

Sunlight‐Driven Green Synthesis of Platinum Nanoparticles From Double‐Vacancy Halide Perovskite Precursors for Methanol Reforming

open access: yesChemistry – A European Journal, EarlyView.
Sunlight‐driven synthesis offers a green and energy‐efficient route to metallic nanoparticles. Here, double‐vacancy halide perovskites (Cs2PtX6, X = Cl, Br) act as photoactive precursors for the in‐situ formation of ultrasmall (< 3 nm) platinum nanoparticles under simulated sunlight at room temperature.

Catalyst‐Free Cyanation of Arenes by Acetonitrile in a Plasma–Liquid Microreactor

open access: yesChemistry – A European Journal, EarlyView.
An original approach of arylnitrile synthesis was developed by generating an argon plasma in contact with solutions of arene in acetonitrile within a gas‐liquid microreactor. Plasma activation of acetonitrile generated cyano radicals, enabling a catalyst‐free C‐H cyanation of arenes.

Peroxodisulfate‐Enhanced Leaching of Deep‐Sea Manganese Crusts and Sulfides

open access: yesChemie Ingenieur Technik, EarlyView.
Ammonium peroxodisulfate enables efficient leaching of deep‐sea manganese crusts and massive sulfides while offering electrolytic recycling. High leaching yields for V, Mn, Co, Mo, Sn, and W, along with complete leaching of As and Sb, highlight its potential as a powerful and sustainable oxidant for marine resource processing.

Waste activated sludge high‐rate treatment of septage: Stabilization phase trials and comparison with winery wastewater treatment

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Performance evaluation of the waste activated sludge high‐rate (WASHR) process for septic wastewater treatment. Abstract The waste‐activated sludge high‐rate (WASHR) process is evaluated as a batch‐mode pre‐treatment for actual septage using a high‐rate contact stabilization (HRCS) approach.

One century of teaching, research, and innovation in chemical engineering in Mexico: The role of chemical engineering in the background and future of polymer science and industrial production in Mexico

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Timeline of key academic milestones and individuals that shaped chemical engineering at FQ‐UNAM and in Mexico. Abstract One hundred years after the beginning of the teaching of Chemical Engineering in Mexico, which started in 1925 in the former National School of Chemical Sciences, currently Faculty of Chemistry (FQ) at National Autonomous University ...

Experimental methods in chemical engineering: The scientific method versus engineering design methodology

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract Engineering graduate students confuse the scientific method and problem solving when presenting their pre‐doctoral exams and theses: Science discourse adopts question and hypotheses to assert and establish a study's rationale, while it is problem and objectives in engineering design.

Integrating Circular Economy and Lean Management: A Strategic Framework for Sustainable Business Transformation

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT This study investigates the integration of circular economy (CE) and lean management (LM) as a strategic approach for enhancing corporate efficiency and sustainability. While CE emphasizes resource circularity, LM focuses on waste elimination and value maximization in production processes.
