Mechanochemical Treatment of Cellulose: A Strategy for Developing Functional Biocomposite Materials

Polymer Engineering &Science, Volume 66, Issue 2, Page 662-688, February 2026.
Mechanochemistry as an integrated approach for combining fiber defibrillation, activation, surface functionalization, and cellulose‐based composite fabrication in a single or reduced number of steps. ABSTRACT Cellulose‐based biocomposites are attracting increasing scientific and industrial interest due to their sustainable origin, biodegradability, and

The Arabidopsis Mutant of the Small Intrinsically Disordered Protein DSS1(V) Exhibits Increased Sensitivity to Drought Stress

Plant Direct, Volume 10, Issue 2, February 2026.
ABSTRACT Drought has emerged as one of the most severe and widespread environmental stresses affecting plants. Crops exposed to varying levels of drought, ranging from moderate to severe, often experience notable declines in yield or reduced harvest quality.

On‐Resin Pictet–Spengler Cyclization for 1,2,3,4‐Tetrahydro‐β‐carboline‐3‐carboxylate (Tcc) Peptide Synthesis With Acid‐Labile Functional Tolerance

Journal of Peptide Science, Volume 32, Issue 2, February 2026.
The constrained tryptophan (Trp) analog 1,2,3,4‐tetrahydro‐β‐carboline‐3‐carboxylic acid (Tcc) is used to restrict peptide conformation in structure–activity relationship studies. Although Pictet–Spengler cyclization of Trp and aldehydes with mineral acid gives Tcc analogs, such harsh conditions do not tolerate acid‐labile functionality.

Surface‐Decoupled Altitudinal and Azimuthal Triptycene‐Fused Tetrapodal Molecular Motors

Angewandte Chemie, Volume 138, Issue 2, 9 January 2026.
Two tetrapodal triptycene‐based light‐driven molecular motors with precisely oriented rotation axes—parallel or perpendicular to a gold surface—achieve full 360° rotation in both solution and as monolayers. The design minimizes surface quenching, enabling functional integration into surface‐mounted nanomachines.

Harnessing Dynamic Self‐Assembly to Accelerate Chemical Reactions

Small Structures, Volume 7, Issue 2, February 2026.
Dynamic supramolecular self‐assembly offers a route to regulate chemical reactivity beyond diffusion‐controlled processes. This perspective surveys how dynamic assemblies organize substrates in space and time, increase effective molarity, enable emergent catalysis, and create specified microenvironments to accelerate chemical reactions. Precise control
