A surface coating of approximate composition Si–30Hf–10Cr (wt. %) was prepared by fused slurry coating method. The metallic particulates in the desired ratio were applied to a graphite specimen in a fluid suspension and vacuum fused at 1450 °C. The metallurgical reactions occurring at the graphite surface were studied by evaluating the coating surface and cross sections using Auger electron spectroscopy, optical metallography, scanning electron microscopy, and x-ray analysis. The results indicat

Articular cartilage exhibits a limited capacity for self-repair, prompting extensive research into advanced biomaterials that can support tissue regeneration. Among these, injectable hydrogels have gained attention for their minimally invasive delivery and suitability for bioprinting applications. However, conventional nanoporous bulk hydrogels often lack the necessary microporosity and architectural complexity to fully support effective tissue regeneration. To overcome these shortcomings, recen
