Novel GH115 xylan α‐1,2‐glucuronidases with distinct preferences for xylan‐derived oligomers and polymers

open access: yesProtein Science, Volume 35, Issue 5, May 2026.
Abstract Natural polymers are promising sustainable materials for diverse applications. Xylans, major components of hemicellulose, exhibit origin‐dependent substitution patterns that determine their physicochemical properties. Targeted enzymatic modification of these substituents offers a mild and precise approach for tailoring the polymer's ...

Dielectric Breakdown Characteristics of Biaxially Oriented Polypropylene Films: Surface Structures on Thickness Dependence

open access: yesHigh Voltage, Volume 11, Issue 2, Page 513-521, April 2026.
ABSTRACT Film capacitors, essential for energy storage in power systems, benefit from reduced film thickness to increase capacitance and lower costs. While the inverse power law traditionally links higher electric strength with thinner films, its validity diminishes below a critical thickness.
