Evaluation of mechanical alloying to obtain Cu-Al-Nb shape memory alloy
Materials Research, 2005 The technical viability of preparing a Cu-Al-Nb shape memory alloy by high energy ball milling in a planetary mill has been evaluated. The alloy Cu-13Al-2Nb (wt. (%)) was prepared by mixing pure elemental powders. A ball-to-powder weight ratio of 6:1 and

3D‐Printed Porous Hydroxyapatite Formed via Enzymatic Mineralization
Advanced Functional Materials, EarlyView.Bone combines lightness, strength, and the ability to heal, inspiring new materials design. This work introduces a room‐temperature, enzyme‐mediated 3D printing method to create porous hydroxyapatite scaffolds. The process avoids energy‐intensive sintering, preserves bioactivity, and allows control over porosity and mineralization.
