We have developed software to help us do our research. We have made these tools available with the links below.

Quantifying Nanoparticle Dispersion

 We developed and demonstrated the use of this code to quantify dispersions of nanoparticles in the article "A quantitative method for measuring nanocomposite dispersion" in the journal Polymer. The code and instructions for use can be found by following the link above.

Characterizing biphasic material properties with Hertzian indentation

 We developed and demonstrated the use of this code to quantify biphasic material properties in the article "Experimental characterization of biphasic materials using rate-controlled Hertzian indentation" in review by the journal Tribology International. The code and instructions for use can be found by following the link above.

Quantifying Transfer film Quality

 We developed and demonstrated the use of this code to quantify dispersions of nanoparticles in the article "Quantitative characterization of solid lubricant transfer film quality" in the journal Wear. The code and instructions for use can soon be found by following the link above.

Lateral Force Calibration for Atomic Force Microscopy

 We developed and demonstrated the use of this code to quantify dispersions of nanoparticles in the article "The extended wedge method: Atomic force microscope friction calibration for improved tolerance to instrument misalignments, tip-offset, and blunt probes" in the journal Review of Scientific Instruments.
