History of Continuing Laboratory Development

The students perform a series of experiments to acquaint themselves with various advanced technologies involved in materials design. The goal is to familiarize the student with apparatus commonly encountered in industrial or academic research laboratories. Emphasis is placed on computer based data acquisition, analysis of data, and integration of complementary techniques in design problems.

The student's grade is based on laboratory reports and two oral presentations. More advanced students may opt to develop some of the experiments into senior research projects which can be published in the Journal of Undergraduate Research.

Effectiveness of Present Equipment

Equipment has been purchased to set up eight experimental stations, a sample preparation area, and a sample analysis area. The equipment is modern, research grade so that the students will familiarize themselves with a variety of apparatus they will encounter in typical professional materials research laboratories.

Experiments

1. Hall Effect:

   The Hall Effect in materials is characterized or exploited in one of two possible experiments. In the first case, the effect, the band gap, and charge carrier concentrations are measured in Ge and Si crystals. In the second case, commercial magnetic-sensors, which use the Hall Effect, are characterized by their type, hysterisis, sensitivity, linearity, and temperature coefficient as a function of applied magnetic field, driving voltage, and temperature.

   An online labreport is available for registered students.

2. Range and Stopping Power of Different Materials of Alpha-particle radiation: (discontinued)

   Students measure the particle energy spectrum from Am, Cu, and Pa à-emitting sources and analyze the pulse shape and height when the particles pass through films of various thicknesses and materials. Relations for stopping power and straggling as a function of atomic number are determined. Conditions for the design of radiation shielding are derived.

3. High Tc Superconductor:

   The transition temperatures of high Tc superconducting discs are determined from the Meisner effect and four-point resistivity measurements. Additionally, the students make their own discs using a press and high-temperature oven. Finally, the structure of the precursor materials and final disc are determined using X-ray diffraction. An online labreport is available for registered students.

4. Interfacial and Surface Energies via Contact Angle Measurements:

   The Young relation for contact angles is used to determine the wetting properties of various liquids on silica, Teflon, high density polyethylene, and polished metal surfaces. The surfaces are then modified via chemical etching, or mechanical polishing to determine the changes induced in the surface energies.
   An online part1, part2, and part3 labreport (PDF ".pdf") is available for registered students.

5. The Effect of Substrate Mechanical Properties on Cell Growth

   An online labreport (".rtf") is available for registered students.

   An online labreport requirements (".txt") is available for registered students.

6. The Mossbauer Effect: (discontinued)

   The Mossbauer Effect is used to study the internal magnetic field in Fe and Fe alloys. The change in the magnetic fields induced by work hardening and/or annealing are then studied.

7. Fracture Toughness of Polymer Interfaces:

   Parallel plates of common incompatible polymers are compression molded and the fracture toughness of the interface after annealing is determined by optical microscope observation of crack propagation. The compatibilization properties of block co-polymers are then demonstrated by measuring the layer increase in fracture toughness when block-copolymers are present at the interface.

   The more advanced student can then opt to continue this project and determine using SIMS, the optional block co-polymer concentration to produce the maximum enhancement in a given blend. The results are often sufficiently unique to enable publication.

8. Magneto Optic Effect:

   The students get to visualize and measure the magnetic/optical properties of a new class of exciting materials. Using several microscopes, the domain size of samples are measured, as a function of applied magnetic field. Additionally, the magnetic saturation, coercivity, and hysteresis are measured by laser-transmission.

   An online labreport is available for registered students.

9. The process of Spinodal Decomposition and Coarsening in Polymer Blends:

   The time and temperature dependence of the spinodal decomposition process in a polymer blend is determined by optical microscope observation of the patterns induced in a polymeric alloy quenched in situ at various temperatures on a Mettler hot stage. The microscope is interfaced with a video data acquisition system and the correlation length of the decomposition process are obtained from a Fourier Transform of the image. The phase diagram of the polymer can then be determined. The more advanced student can continue to perform SIMS and determine the concentration of the polymers in the co-existing phases of the alloy.

10. Nanocomposites:

    An online labreport (MSWord ".doc") is available for registered students.
