Enhancing the Functional Properties of Polylactic Acid by Incorporation of Esterified Lignin

open access: yesJournal of Polymer Science, Volume 64, Issue 7, Page 1625-1637, 1 April 2026.
Esterified lignin from agro‐industrial wastes enhances the hydrophobicity, UV‐shielding efficiency, and antioxidant capacity of polylactic acid composites. ABSTRACT Incorporating lignin as an additive is a promising strategy to overcome the limitations of PLA‐based composites.

Aged Tyrosine Enriched Plasma‐Treated Water Solutions Retain Anticancer Activity Against Head and Neck Cancer Cells

open access: yesPlasma Processes and Polymers, Volume 23, Issue 4, April 2026.
Despite therapeutic advances, HNC remains a major public health issue due to high recurrence and metastasis rates. The paper shows that PTWS formulations containing tyrosine selectively target cancer cells while sparing healthy ones after 2 weeks storage at room temperature, laying the foundation for future clinical translation in HNC therapy ...

Synergistic Effects of Mesoporous Structure and Oxygen Vacancies in SnO2 for Enhanced CO2 Electroreduction

open access: yesSmall Science, Volume 6, Issue 4, April 2026.
Mesopores in SnO2 increase the number of active sites and oxygen vacancies, strengthen intermediate stabilization, and improve structural stability, enhancing CO2 to formate conversion. Electrocatalytic CO2 reduction (CO2RR) into value‐added chemicals represents a promising strategy for sustainable CO2 utilization.

Biocatalytic Epoxidation Pathway of Oils in Sponge‐Like Ionic Liquids Toward CO2‐Derived Cyclic Carbonate Synthesis

open access: yesChemSusChem, Volume 19, Issue 5, 13 March 2026.
A sustainable chemo‐enzymatic synthesis of poly(cyclic carbonate)s from CO2 and renewable oils is reported for the first time using sponge‐like ionic liquids as reaction media by two sequential steps: epoxidation and CO2 cycloaddition. A sustainable chemo‐enzymatic synthesis of poly(cyclic carbonate)s from CO2 and renewable oils is reported for the ...

Positronium reflection and positronium beams [PDF]

open access: yes
Specular reflection of positronium, Ps was observed and that there is adequate intensity at higher energies to make further study worthwhile was established. The scattering appears to be restricted to the outermost surface with a mean free path of (0.75 +
