Mighty Metals
Chromium is added to alloys to prevent corrosion by the formation of this
What is an oxide layer (or passivation)
What is HA or bone
Most polymers are made up of these 2 simple elements
What are H and C
If this technique was used on all the glass panes in Squid Games, nobody would have fell to their death
What is tempering
This degradable metal is no trick; while still in research and development its natural presence in the body make it an ideal choice
What is Mg
This metal wants to get as close to possible to bone, there is no fibrous capsule formation here!
What is titanium
What is concentrated
This type of polymerization reaction yields smaller repeat units and releases something in the process, usually water
What is condensation
This technique coalesces particles and reduces pore size
What is sintering
Liquidus and solidus may sound like Hogwart spells but are really just components of this graphing system which provides information about composition, usually of metals.
What is a phase diagram
Shape memory and superelasticity are traits of this nifty metal
What is Nitinol
Hard joint systems like alumina-on-alumina are only possible due to advances in this
What is surface polishing techniques
This polymer may be found in your eye, or may be found in your window, but clearly you will know what it is
What is PMMA
This technique may produce something that looks like cotton candy, but you best not eat it
What is electrospinning
What is the fibrous capsule
This alloy is really strong and has corrosion resistance but not so much under stress, so it's best to use these mainly in temporary implants.
What is stainless steel
Bone is a natural composite of these 2 material classes
What are ceramics and polymers
The practice of growing cells on degradable polymer scaffolds to produce material native to the human is body is known as this
What is tissue engineering
Salt and freeze-drying techniques are often used to create this type of structure in polymer scaffolds
What are pores
Head shoulders knees and toes...knees and ankles are known as this type of joint
What is incongruent
This alloy has excellent fatigue and stress corrosion resistance but metal toxicity could be an issue for some
What is cobalt-chromium
Cooling rate and ion substitutions can alter this, which can be used to fine tune degradation rates
What is crystallinity
This no stick material is great for your blood vessels, and also your cookware
What is Teflon
This technique produces strong metal parts with a favorable grain structure by redistributing impurities and reducing inclusions
What is forging
It's not magic, but this process can eliminate the immune response of tissue implanted from one host (or even species!) to another
What is decellularization
