Dec 3 2024 - Expanded Introduction: Adds information on engineering advancements, including regenerative biomaterials, zwitterionic biomaterials, and smart 3D-printed materials. Added Metallic Biomaterials Section: Summarized 3D printing techniques (SLS, SLM, EBM) and their applications in implants and dental uses with titanium and zirconia for enhanced biocompatibility. Expanded Polymeric Biomaterials: Included advancements in smart polymers (SMPs, hydrogels), sustainability efforts (natural-source polymers), and applications like wound healing, cardiovascular implants, and cosmetic enhancements. New Ceramic Biomaterials Section: Introduced innovations in ceramic materials (e.g., alumina, bioactive glass) for orthopedic, dental, and cancer theranostic uses. Composite Biomaterials Section Added: Discussed hybrid materials (e.g., mycelium-based composites) for bone regeneration and novel applications like bladder scaffolds. Emerging Biomaterials Classes: Highlighted functional amyloids (3D cell culturing, tissue engineering) and piezoelectric materials for energy harvesting and advanced medical devices. The new article is more comprehensive and systematically organized, with clear headings for each biomaterial type and their applications. Includes recent studies and specific examples to support the information provided.

An Overview of Biomaterials: Advancements and Applications

Nov 22 2024 - The new article begins with key properties and applications, followed by standards and composition, physical and mechanical properties, and then heat treatment. This reordering prioritizes practical information for users before diving into technical details. The old article had a less structured flow, mixing general properties with technical details. Introduces ASTM standards and comparison to other grades like M1030 and 4140, making the composition section more comprehensive and actionable.

AISI 1045 Medium Carbon Steel

Oct 25 2024 - The new article introduces comfort and mobility as key considerations in body armor, shifting from purely protective design to ergonomic and operational versatility. Adds nanomaterials like carbon nanotubes (CNTs) and graphene as well as smart textiles with phase change materials and shear-thickening fluids for dynamic protection—absent in the old article. New applications cover military, law enforcement, and sports sectors, detailing specific innovations like spider silk fibers and 3D-printed helmets with sensors, which were not addressed in the original. The updated article highlights reactive body armor and smart textiles for temperature regulation as future directions, unlike the original which briefly noted incremental material improvements.
