Inherited metabolic epilepsies–established diseases, new approaches

Epilepsia Open, EarlyView.
Abstract Inherited metabolic epilepsies (IMEs) represent the inherited metabolic disorders (IMDs) in which epilepsy is a prevailing component, often determining other neurodevelopmental outcomes associated with the disorder. The different metabolic pathways affected by individual IMEs are the basis of their rarity and heterogeneity.

The effect of gamma radiation on mechanical properties of biodegradable polymers poly(3-hydroxybutyrate) and poly(3-hydroxybutyrate-co-3-hydroxyvalerate)

Materials Research, 2012
Brazilian poly(3-hydroxybutyrate), P(3-HB), and its copolymer, poly (3-hydroxybutyrate-co-3-hydroxyvalerate), P(3-HB-co-3-HV) were irradiated with gamma radiation (60Co) at room temperature and in the presence of oxygen. The viscosity-average molar mass (

From Molecule to Material: How Support Changes Heterobimetallic Catalysts in Lactide Polymerization

Macromolecular Rapid Communications, EarlyView.
Silica‐supported heterobimetallic alkoxide complexes were developed as catalysts for lactide ring‐opening polymerization. Grafting iron‐based ate complexes onto SiO2‐700 produced well‐defined active sites, enabling controlled polymerization with predictable molar masses, narrow dispersities, and recyclability.

Mono‐Materials Created by Engineering a Continuum of P3HB Stereomicrostructures in a One‐Step Catalytic Process

Angewandte Chemie, Volume 138, Issue 3, 16 January 2026.
Diastereomeric mixtures of diolide were polymerized to P3HB mono‐materials that behave like thermoplastics, thermoplastic elastomers, and pressure‐sensitive adhesives, which were then combined to create all‐P3HB mono‐material tapes. Abstract Multi‐material products that combine multiple complementary polymers can create products with desired ...
