BioE 201-exam 1
Bioengineering is sometimes referred to as... - correct answer ✔biomedical
engineering or Integrated Innovative Technology
to Improve Human Health
Bioengineering integrates what principles... - correct answer ✔physical,
chemical, mathematical, computational sciences and engineering principles to
study behavior, health, medicine and biology
Bioengineering develops... - correct answer ✔innovative biologics, materials,
processes, implants, devices and informatics approaches for the prevention,
diagnosis, and treatment of disease, for patient rehab and health
improvement.
Major Focus areas of BioE - correct answer ✔Biomaterials,
bioinstrumentation, biomechanics, biochemical/bioprocess engineering, cell
and tissue engineering.
List some BioE breakthroughs - correct answer ✔Dialysis, Heart lung bypass
machine, ortho implants for knees and hips, pacemakers, valves, contact
lenses, MRI, Angiography, min invasive surgery& computer assisted surgery,
bio artificial skin
IDES - correct answer ✔Internal Documentation and Evaluation System
Where do BioE's work - correct answer ✔Industry-dev, design, research.
Hospitals, Academics, Gov. Patent Office, FDA
, Why Bio E? - correct answer ✔Increased life expectancy-increasing burden
of age related, chronic conditions
polymers - correct answer ✔A linear polymer is a polymer molecule in which
the atoms are more or less arranged in a long chain. This chain is called the
backbone.
pendant groups - correct answer ✔small chains of atoms attached to the
backbone of a polymer
Repeat Structure or unit - correct answer ✔The repetitive pattern of
molecules in a polymer's backbone. Placed in brackets with an "n" on the
outside, denoting multiple sets.
Three things that make polymers different - correct answer ✔Chain
entanglement, summation of intermolecular forces, time scale of motion
Chain entanglement - correct answer ✔the polymer chain can get tangled up
when cold--like spaghetti. This makes them strong--it's why we like plastics,
paint, elastomers and composites.
Summation of intermolecular forces - correct answer ✔With polymers, these
forces are greatly compounded. The bigger the molecule, the more there is to
exert an intermolecular force. All molecules, both small ones and polymers,
interact with each other, attracting each other through electrostatics. Polar
molecules stick together better than nonpolar molecules. For example, water
and methane have similar molecular weights, 16 and 18. Methane is a gas at
room temperature, and water--liquid. This is because water is very polar, polar
enough to stick together as a liquid, while methane is very nonpolar, so it
doesn't stick together very well at all.Polyethylene, for example is very
nonpolar
