Photodegradation of Acidolysis Lignin from BCMP

, 2008
A mild acidic dioxane extraction method was employed to isolate lignin from hardwood bleached chemimechanical pulp (BCMP). The isolated lignin was then purified and undergone elemental analysis.

Triptycene‐Based Tripodal Molecular Platforms: A Comparative Study of Photoswitchable Langmuir–Blodgett Films on Metallic and Nonmetallic Surfaces

Chemistry – A European Journal, EarlyView.
A modular triptycene‐based platform enables the preparation of Langmuir–Blodgett monolayers of structurally diverse molecular photoswitches on quartz and gold. Surface‐sensitive characterization and optical spectroscopy demonstrate that the intrinsic switching behavior is retained after surface immobilization. ABSTRACT Photoswitchable molecular systems

Photostability of Cyanine Dyes and Its Correlation to Their Photothermal and Photodynamic Effects

Chemistry – A European Journal, EarlyView.
Photostability (PS) of dyes is a crucial parameter for performance in biological applications, yet often underrated. Here PS of several cyanines is investigated. The method is carefully evaluated and designed as a general and easy tool to compare PS of NIR dyes.

High Fatigue‐Resistant Photoswitches Based on iridium(III)‐DTE Systems

Chemistry – A European Journal, EarlyView.
Coordination to iridium(III) enhances fatigue resistance over multiple photoswitching cycles in diarylethenes. This metal coordination modulates photoresponse relative to the free ligands under identical irradiation conditions, opening new avenues for practical applications.'' ABSTRACT A series of four differently substituted nonsymmetrical ...

Soil Decomposer Can Regulate the Legacy Effect of Photodegradation on Forest Marcescent Litter Decomposition, but Emerging Microplastics Disrupt This

Ecology and Evolution
Photodegradation—photochemical mineralization of standing litters—often exerts a legacy effect aiding biodegradation in soil (PLE), which is overlooked in deciduous forests containing marcescent leaves.

Oxygen‐Vacancy‐Engineered Ru–V Dual Sites in InVO4 for Synergistic Photocatalytic N2 Activation and Reactive Hydrogen Supply

EcoEnergy, EarlyView.
This study developed a catalyst composed of Ru nanoparticles directionally anchored at the oxygen vacancies of indium vanadate. Oxygen vacancy not only forms unsaturated V sites but also serves as an anchoring site for Ru nanoparticles, establishing a stable Ru‐V coordination structure through electronic metal–support interactions.
