Linear Viscoelastic Behavior of n‐Alkane Diluted Polyethylene Melts: Sorption, Desorption, and Oscillatory Rheometry

Journal of Applied Polymer Science, Volume 143, Issue 39, October 15, 2026.
This study systematically maps polyolefin dilution dynamics using a homologous series of n‐alkanes. Integrating gravimetric sorption, subsequent controlled desorption, and oscillatory rheometry establishes a precise framework to analyze reduction in viscosity at least for polymer diluent mixtures with polymer concentration > 35% and diluent ...

Chemoenzymatic Synthesis of (4R,7R)‐Zingiberene Enables Construction of nor‐Sesquiterpene Semiochemical Analogs

ChemBioChem, Volume 27, Issue 19, 14 October 2026.
A five‐enzyme chemoenzymatic synthesis of the insect‐repellent (4R,7R)‐zingiberene from the wild tomato (Solanum habrochaites) has been developed. This approach enabled the elucidation of the sesquiterpene synthase cyclization mechanism of (2Z,6Z)‐farnesyl pyrophosphate and bypasses classic biosynthetic constraints of prenyltransferase chain extension ...

Record Dissymmetry in Vibrational Optical Activity: Combining Vibronic Coupling and Aggregation in Cobalt(II) Camphorate Complexes

Angewandte Chemie, Volume 138, Issue 42, 12 October 2026.
The cobalt(II) bis(trifluoroacetylcamphorate) scaffold exhibits versatile coordination chemistry with solvent‐driven ligand exchange and geometrical rearrangements, associated with unique chiroptical properties. Microcrystalline suspension of [Co(tfc)2(CH3CN)2] revealed the largest VCD dissymmetry factor ever reported (g ≈ 0.2 at 1600 cm−1), arising ...

Dual Porphyrin Sensitized Photocatalytic System for Visible‐Light‐Driven CO2 Reduction

ChemSusChem, Volume 19, Issue 19, 14 October 2026.
Dual porphyrin–sensitized TiO2 enables efficient visible‐light CO2 reduction by integrating Zn‐porphyrin photosensitization with urea‐functionalized Fe‐porphyrin catalysts. Immobilization enhances charge separation, activity, and durability, while tuning electron donor and proton availability reveals key aspects that influence this catalytic conversion.

Photosensitizing Au(I) Catalysis With Coumarins

Chemistry – A European Journal, Volume 32, Issue 38, 13 October 2026.
A Au(I) complex with a tethered coumarin fragment was synthesized and characterized by UV‐vis and emission spectroscopy. Its ability to facilitate photo‐driven cross‐coupling reactions through single‐electron and energy transfer events was evaluated. ABSTRACT Gold catalysis shows versatility in a wide range of challenging transformations, wherein light‐

An Iridium Distannylidyne – Expanding the Scope of Tetrylidyne Transition Metal Coordination Chemistry

Angewandte Chemie, Volume 138, Issue 41, 5 October 2026.
This work presents the synthesis, characterization, and reactivity of an iridium distannylidyne as the first heavy transition metal ditetrylidyne. Characterized by its short Ir─Sn bonds and linear bonding angles at the tin atoms, this compound displays versatile reactivity toward carbon dioxide and trimethylsilyl azide.
