  2. What is the smallest size you can typically get an end mill to machine metal? • 1 in • 1/8 in • 1/64 in • 1 nm

  3. Which liquid has the lowest viscosity? • Water • Motor oil • Corn Syrop • All the same

  4. When will water flow without turbulence? • When the Reynold’s number is very large. • When the Reynold’s number is very small.

  5. Why is gold useful in our PCR devices? • Because it is a very good reflector of infrared. • Because it conducts electricity very well. • Because you can get it to stick to PMMA easily. • Because it is so expensive.

  6. What solvent did we find improved the adhesion of gold to acrylic surfaces? • Isopropyl alcohol • Chloroform • Hexanes • water

  7. Where did we have to go to do XPS measurements to determine exactly how the Cl and Au were bonded to the PMMA? • Jefferson National Lab • University of Virginia • Naval Research Lab • Oak Ridge National Lab
