The Map All Biomaterialists Should Understand

We know various material types (e.g., metals, ceramics, polymers) can be used as raw materials to develop an implant or device. We also know composites comprise of more materials. The manufacturing processes shape and assemble the materials into the final product. Heating and cooling techniques are routinely employed during the manufacturing process to shape and deposit the materials. These techniques generate microstructures (typically visible only under a microscope) that play an important role in defining the final product properties. During material’s thermal processing, understanding the nature of phase transformations that give rise to various microstructures is crucial for control of final product properties. Central to this understanding of phase transformation is to have a good grasp of phase diagrams or “maps” for the design of processing methods. So let us delve a little bit more into phase transformation and phase diagrams.

The Insect That Keeps Giving

Materials derived from insects and plants were frequently used in healthcare. The honeybee is an insect that has been of great importance to human society since ancient times across various cultures. Anytime you take a bite of a fruit or vegetable, it is highly likely a honeybee was an important cog in the growth of that produce. Honeybees are excellent pollinators. The United State Department of Agriculture (USDA) estimates that bees pollinate 80% of our crops.  Bee-based products are widely used in food and medicine. Bee materials used in these products include honey, bee pollen, royal jelly or bee milk, bee venom, propolis, beeswax, and silk.

Once Tooth Blings Were In Vogue

The Mayans replaced their teeth with false teeth carved out of a ceramic material sourced out of sea shells called nacre or mother of pearls. These replacements with gem-studded teeth were not part of a dental treatment but for cosmetic effect. This procedure would have affected their eating habits but could have improved their smile.
