Lecture 6 (BME 296)

Cobalt-Chromium

A material known for its corrosion resistance, often used in hip implants.

Plastic Material

A type of material that deforms easily when stress is applied; reducing plasticity often involves changing its composition or structure.

Genetic Engineering

A field of biology that involves the direct manipulation of an organism's genes using biotechnology.

Bulk Polymerization

A polymerization technique that involves the reaction of monomers and initiators without a solvent, resulting in high purity.

Solution Polymerization

A method where polymerization occurs in a solvent, with monomers and an initiator, to aid in heat transfer.

Suspension Polymerization

A polymerization process where monomers and initiators that are not soluble in water form droplets in a stirred water medium.

Emulsion Polymerization

A process involving the emulsification of monomer droplets in water with the addition of surfactants to form polymer nanoparticles.

Pyrolytic Carbon

Carbon that is deposited from gaseous state onto a substrate, notable for its biocompatibility and thromboresistance.

Mass Spectrometry

An analytical technique that measures the mass-to-charge ratio of ions to identify and quantify materials.

Nuclear Magnetic Resonance (NMR) Spectroscopy

A technique that uses magnetic fields and radio waves to examine molecular and atomic interactions based on nuclear spin.

Beer-Lambert Law

A principle stating that the absorbance of light by a substance is directly proportional to its concentration in a solution.

X-ray Diffraction (XRD)

A technique used to determine the crystal structure of materials by analyzing the patterns of X-ray scattering.

Chromatography

A method for separating mixtures based on differences in the chemical or physical properties of components.

Polymer Beads

Solid particles formed during polymerization, often recovered by filtration after the reaction.

Hydrophobic Polymer

A polymer that repels water and does not dissolve in aqueous solutions.

Covalently Bonded

A type of chemical bond where atoms share pairs of electrons.

Biocompatible Material

Materials that do not elicit an adverse reaction when implanted in the body.

Thromboresistant

A property of materials that resist blood clot formation.

Crystalline Phases

Different structural forms of a material that develop under varying conditions.

Osteogenic Coating

A layer applied to implants to promote bone growth and integration.
