Citric Acid‐Crosslinked Chitosan Coatings Incorporating Curcumin for Enhancement of Antioxidant and Antimicrobial Properties

Journal of Vinyl and Additive Technology, Volume 32, Issue 6, Page 1573-1592, November 2026.
A fully bio‐based coating was developed using Chitosan, Citric acid, and Curcumin. Citric acid acts simultaneously as a green solvent and non‐toxic crosslinker. Dry Heat Treatment enhances water resistance and thermal stability, creating an active packaging system with dual antioxidant and antimicrobial properties to extend food shelf‐life.

Novel Biorenewable Composites Based on Poly (3-hydroxybutyrate-co-3-hydroxyvalerate) with Natural Fillers

Journal of Polymers and the Environment, 2019
Due to the ubiquity and single-use character of plastic products, their production represents a burden to the environment. Therefore, an increasing interest in biodegradable and bio-compostable materials has been observed in the recent years.

Histone Modifications at the Intersection of Aging, Neuroinflammation and Metabolism in Alzheimer's Disease

Aging Cell, Volume 25, Issue 11, November 2026.
This review examines how histone modifications integrate aging, metabolic dysfunction and neuroinflammation to shape persistent, cell‐type‐specific chromatin states in Alzheimer's disease. By distinguishing causal regulation from association through perturbation, persistence and reversibility, it highlights metabolic–epigenetic feedback loops and ...

Production of poly(3-hydroxybutyrateco-4-hydroxybutyrate) in recombinant Escherichia coli grown on glucose

, 1997
A recombinant Escherichia coli strain has been developed that produces poly(3-hydroxybutyrate-co-4-hydroxybu-tyrate) when grown in complex medium containing glucose. This has been accomplished by introducing into E.

Improving the Mechanical Properties of Biodegradable Polyhydroxyalkanoates via PHA–PHA Block‐Copolymer Synthesis

Chemistry – A European Journal, Volume 32, Issue 39, 22 October 2026.
Covalent linkage of a highly crystalline PHBV with a ductile P3HB4HB is shown to produce block copolymers with markedly enhanced extensibility and toughness, outperforming equivalent blends. The results demonstrate that polymer architecture, not composition alone, governs mechanical response, offering a route to biodegradable materials that combine ...
