Nitrogen‐Rich, Tröger's Base‐Linked Porous Organic Polymers (POPs) as Heterogeneous Catalysts and Adsorbents of Organic Pollutants From Water

Journal of Applied Polymer Science, Volume 143, Issue 3, January 15, 2026.
Synthesized Tröger's based POPs showed great versatility in heterogeneous catalysis reactions and for pollutant adsorption. ABSTRACT Porous organic polymers are a new class of polymeric materials that combine permanent porosity, high surface area, monomer diversity, and synthetic tunability, making them highly promising candidates for application in ...

Analysis of Methyl Substitution in Phenolic Compounds as Potential Biofuel Additives: From Solid‐State Description to Antioxidant Potential

ChemistrySelect, Volume 11, Issue 2, 15 January 2026.
The rising demand for renewable energy points to biodiesel as a viable fossil fuel alternative, yet its limited oxidative stability remains a challenge. This study reveals that methyl‐substituted hydroquinone derivatives exhibit enhanced antioxidant capacity, suggesting their promise as biofuel additives.

Magnetic Hopfions as Local Rotations of the Uniform Magnetization Background

physica status solidi (RRL) – Rapid Research Letters, Volume 19, Issue 12, December 2025.
The Hopf mapping of 3D coordinate space to the unit sphere m2 = 1 in the magnetization space m(r) can be parametrized by some angles. These angles are used to define a local rotation matrix to restore the hopfion magnetization configuration from the uniformly magnetized state for any Hopf indices.

Physiological roles of lignins – tuning cell wall hygroscopy and biomechanics

New Phytologist, Volume 248, Issue 6, Page 2674-2706, December 2025.
Summary Lignins constitute the second most abundant carbon‐storing biopolymers in the biosphere. These phenolic polymers accumulate in different concentrations, compositions, and localisations within and between cell wall layers and cell types. Lignins were acquired during plant terrestrialisation 450 million years ago, and the diversification of their
