Recycling alkali lignin-derived biochar with adsorbed cadmium into cost-effective CdS/C photocatalyst for methylene blue removal.

Cadmium (Cd)-enriched adsorbents wastes possess great environmental risk due to their large-scale accumulation and toxicity in the natural environment. Recycling spent Cd-enriched adsorbents into efficient catalysts for advanced applications could address the environmental issues and attain the carbon neutral goal. Herein, a facile strategy is developed for the first time to reutilize the alkali lignin (AL)-derived biochar (ALB) absorbed with Cd into cadmium sulphide (CdS)/C composite for the efficient methylene blue (MB) removal.

Comparative Analysis of Intramedullary Nail versus Plate Fixation for Fibula Fracture in Supination External Rotation Type IV Ankle Injury.

BACKGROUND Lateral malleolus fractures, typically from trauma, sports, or accidents, are common, with supination external rotation (SER) injuries being most prevalent. SER injuries involve complex joint mechanics and often necessitate surgical intervention for instability. This study compares intramedullary nail and plate fixation for fibula fractures in SER type IV ankle injuries, considering their biomechanical properties and influence on fracture healing.

Polyethyleneimine-modified iron-doped birnessite as a highly stable adsorbent for efficient arsenic removal.

Remediation of arsenic contamination is of great importance given the high toxicity and easy mobility of arsenic species in water and soil. This work reports a new and stable adsorbent for efficient elimination of arsenic by coating polyethyleneimine (PEI) molecules onto the surface of iron-doped birnessite (Fe-Bir). Characterization results of surface microstructure and crystalline feature (scanning electron microscopy (SEM), X-ray diffraction (XRD), Fourier transform infrared spectrometer (FTIR) and X-ray photoelectron spectroscopy (XPS), etc.

Biomaterial-Based Gene Delivery: Advanced Tools for Enhanced Cartilage Regeneration.

Gene therapy has emerged as a promising and innovative approach in cartilage regeneration. Integrating biomaterials into gene therapy offers a unique opportunity to enhance gene delivery efficiency, optimize gene expression dynamics, modulate immune responses, and promote tissue regeneration. Despite the rapid progress in biomaterial-based gene delivery, there remains a deficiency of comprehensive discussions on recent advances and their specific application in cartilage regeneration.
