Bio‐Inspired Sclerotization of Lignin: A Robust Adhesive for Photothermal Wood‐Based Panels

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A high‐performance lignin adhesive is engineered via an insect‐inspired sclerotization strategy involving oxidation and hyperbranched polymer grafting, overcoming lignin's adhesion failure, and yielding a wet shear strength of 1.02–1.21 MPa. The adhesive endows wood‐based panels with photothermal functionality; building energy simulations indicate HVAC‐

Klippel‐Trénaunay‐Weber Syndrome: Prenatal Diagnosis and Review of the Literature

open access: yesJournal of Clinical Ultrasound, Volume 53, Issue 3, Page 535-546, March/April 2025.
This meta‐analysis demonstrates the high diagnostic accuracy of SZ‐CEUS for differentiating between malignant and benign focal liver lesions, as well as for HCC from non‐HCC lesions. The study shows better performance for smaller lesions and those with a higher proportion of malignancy.
