SIMMAP Research Group Publishes New Journal Article

The SIMMAP Research Group, led by Dr. Talha Khan, in collaboration with Dr. Rajeev Nair, is pleased to announce the publication of a new journal article in Journal of Materials Science: Materials in Medicine.

This work investigates nanosecond-pulsed laser surface texturing of stainless steel, titanium, and cobalt-chromium alloys for biomedical applications, with a focus on enhancing surface functionality and biocompatibility. The study demonstrates how controlled laser-engineered micro-topographies can significantly influence surface morphology, wettability, and cellular response, which are critical factors for implant integration and performance.

Through a combination of experimental fabrication, surface characterization (SEM, profilometry, and contact angle analysis), and multiphysics-based numerical modeling, the research establishes a clear relationship between laser processing parameters and resulting surface properties. The results show that laser-textured surfaces exhibit improved hydrophilicity and enhanced potential for cell adhesion, particularly in stainless steel, while maintaining minimal oxidation under controlled processing conditions.

This work highlights the capability of laser-based surface engineering as a scalable and precise manufacturing approach, bridging simulation and experiments to design functional surfaces for next-generation biomedical devices. It further reflects the lab’s broader efforts in multiphysics-driven, sustainable, and intelligent manufacturing and materials processing.
