Breaking the ORR Trade‐Off via Mg‐Steered Fe‐N4 Pyridinic Conversion

open access: yesSmall, EarlyView.
A Mg‐assisted sacrificial templating strategy is developed to selectively regulate the coordination environment of Fe–N4 sites. This approach induces an active site conversion from S1 to S2, enabling enhancement of oxygen reduction activity and durability. ABSTRACT Single‐atom Fe sites coordinated by pyrrolic nitrogen (Fe‐Npyrr‐C) are highly active for

Alkaline Depolymerization of Polyethylene Terephthalate Plastic Waste

open access: yesTikrit Journal of Engineering Sciences, 2016
Depolymerization reaction is considered one of the most significant ways of converting waste polyethylene terephthalate in to terephthalic acid. The water polyethylene terephthalate bottle waste was collected from different places in Baghdad.

pH‐dependent electrochemical oxidation of 5‐hydroxymethylfurfural: Reaction mechanism, catalyst design, and reactor design across alkaline to acidic media

open access: yesSmart Molecules, EarlyView.
This review summarizes the progress in pH‐dependent electrochemical oxidation of 5‐hydroxymethylfurfural for value‐added chemical production. It highlights how pH dictates reaction mechanisms and product selectivity, discusses strategies for designing effective electrocatalysts tailored for alkaline, near‐neutral, or acidic electrolytes, and explores ...

Platinum–Copper Dual‐Atom Catalyst Enables the Selective Electro‐Oxidation of 5‐Hydroxymethylfurfural to 2,5‐Furandicarboxylic Acid

open access: yesSusMat, EarlyView.
A platinum–copper dual‐atom catalyst was developed for the selective electrooxidation of 5‐hydroxymethylfurfural (HMF) to 2,5‐furandicarboxylic acid (FDCA) in alkaline solution, achieving a FDCA yield of 97.4% at 1.42 V. DFT and experimental analyses reveal that Pt atoms enrich the OH* coverage, driving deep oxidation of HMF on adjacent Cu atoms ...

Chemical Characterization of Postindustrial Recycled Polyethylene Terephthalate Obtained From Multilayer PET/PE Sheets: A Baseline Study on Safety Aspects

open access: yesPackaging Technology and Science, Volume 39, Issue 3, Page 257-270, March 2026.
PET trays pose recycling challenges due to multilayer structures with polyethylene (PE) tie‐layers and barrier materials. In this study, a delamination process using a hot alkaline solution was applied to postindustrial multilayer PET/PE thermoforming waste to recover PET flakes and produce sheets.
