Extrusion and Pancreatin Superdosing Modulate the Metabolic Impact of 20% Chlorella vulgaris Inclusion in Broiler Diets

Journal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT Microalgae such as Chlorella vulgaris are gaining attention as sustainable and nutritionally valuable feed ingredients, with the potential to partially replace soybean meal in broiler diets. However, dietary inclusion of 20% C. vulgaris has been attempted, but negatively affected growth performance due to limited digestibility.

Synergistic Lewis Acid Photocatalysis Over Cluster‐Defect‐Engineered UiO‐66 for Efficient Liquid Biomass Upgrading

Angewandte Chemie, Volume 138, Issue 27, 1 July 2026.
A cluster‐defect engineering strategy is presented for the rational design of Zn‐incorporated UiO‐66 photocatalysts. Selective acid etching mediates hierarchical porosity and abundant Lewis acid sites, tailoring the electronic structure and enhancing light harvesting.

Writing Big in Plant Genomes: Advances, Challenges and Strategies for Targeted Large‐Fragment DNA Insertion

Plant, Cell &Environment, EarlyView.
ABSTRACT Precise genome editing has transformed plant biology and crop improvement by enabling targeted modification of endogenous loci. Beyond gene knockout and base editing, the site‐specific insertion of exogenous DNA, particularly large DNA fragments, has become a central goal for engineering complex traits, reconstructing metabolic pathways and ...

Biobased Polyurethane Films Based on Andiroba (Carapa guianensis) and Buriti (Mauritia flexuosa) Oil Polyols

Journal of Applied Polymer Science, Volume 143, Issue 30, August 10, 2026.
Polyurethane films were prepared from andiroba (Carapa guianensis) and buriti (Mauritia flexuosa) oil‐derived polyols, emphasizing their potential as bio‐based materials. UV–Vis analysis indicates the retention of carotenoid‐related chromophoric features within the polymer matrix.
