The Effectiveness of Polyhydroxyalkanoate (PHA) Extraction Methods in Gram-Negative U.

Bioplastics are emerging as a promising solution to reduce pollution caused by petroleum-based plastics. Among them, polyhydroxyalkanoates (PHAs) stand out as viable biotechnological alternatives, though their commercialization is limited by expensive downstream processes. Traditional PHA extraction methods often involve toxic solvents and high energy consumption, underscoring the need for more sustainable approaches.

The journey of a living statue: Structural violence and a Honduran migrant woman's pathway toward asylum and wellbeing.

Approximately half of the world's displaced migrant population are women, yet gender-specific analyses are often lacking. Such analyses are crucial for understanding migrant women's unique experiences and informing policies that address their health and broader needs. This paper integrates the concept of structural violence with person-centered ethnography to examine women's physical and mental health in contexts of displacement and migration.

Bio-oil Fractionation According to Polarity and Molecular Size: Characterization and Application as Antioxidants.

Bio-oil obtained from biomass pyrolysis has great potential for several applications after being upgraded and refined. This study established a method for separating bio-oil into different fractions based on polarity and molecular size to extract phenolic and polyphenolic compounds with antioxidant properties. The fractions were analyzed using various spectroscopic and chromatographic techniques, such as GC/MS, FTIR, UV-vis, SEC, DOSY-NMR, C-NMR, and P-NMR.
