Characteristics of Chromophoric Dissolved Organic Matter (CDOM) Produced by Heterotrophic Bacteria Isolated from Aquaculture Systems

Journal of Marine Science and Engineering, 2022
Heterotrophic bacteria (HB) play an important role in aquatic ecosystems as recyclers of dissolved organic matter (DOM). The objective of this study was to characterize the spectral characteristics of intracellular (IC), and extracellular (EC) compounds ...

Host–Guest Interactions Govern Drug Stability and Controlled Therapeutic Release: Based on Metal–Organic Frameworks as Smart Platforms

Rare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT Due to their exceptional porosity, structural versatility, and modular coordination chemistry, metal–organic frameworks (MOFs) have emerged as versatile platforms for targeted drug delivery. These structures enable fine‐tuning of pore size, surface activity, and framework stability for the encapsulation of a broad range of therapeutics ...

Seasonal dynamics of dissolved organic matter in a small tropical estuary-coastal bay continuum: distribution, transformation, flux, and global perspectives

Frontiers in Marine Science
The export and transformation of riverine dissolved organic matter (DOM) at the river-sea interface are critical to understanding carbon budgets in tropical regions, yet remain underexplored in small watersheds.

Enzyme–MOF Composites: Quantitative Benchmarking and Evaluation of Biocatalyst Performance

Advanced Synthesis &Catalysis, Volume 368, Issue 13, 2 July 2026.
Rigorous evaluation of enzyme@MOF composites requires quantitative benchmarking. This study illustrates this approach by applying and comparing enzyme‐loading and activity‐assessment strategies for two structurally and functionally distinct enzymes, phenolic acid decarboxylase, and cytochrome c.

Antioxidants in Plant‐Based Food Matrices: From Structure–Activity and Degradation Kinetics to Formulation Design

Comprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 4, July 2026.
ABSTRACT Plant‐based antioxidants are widely incorporated into foods to retard oxidative deterioration and to deliver health‐related benefits. Yet, their in‐product and in vivo performance frequently diverges from predictions based on solution‐phase chemical assays, because matrix interactions, processing history, and host metabolism reshape both ...

Ion‐Pairing and Counterion Effects in Contemporary Photochemistry

Angewandte Chemie Novit, Volume 2, Issue 2, June 2026.
Ion‐pairing and counterion effects have emerged as fundamental yet underexplored determinants of photochemical behavior. Far from inert, counterions, and Coulombic interactions modulate excited‐state dynamics, quenching efficiencies, emission, and catalytic pathways.
