Dr. Lindner is a member of the American Chemical Society, Polymer Chemistry Division, American Physical Society, Diversion of High Polymer Physics, and the American Institute of Aeronautics and Astronautics. Most all of these studies involve the use of lasers. Techniques such as photon correlation spectroscopy, static light scattering and viscosity are used to study polymer chain behavior in solution. These methods complement one another and provide information on coil size and molar mass, chain mobility, shape, solvent permeation, and secondary interactions.
Work is also in progress on liquid crystals.
In all cases the results are compared to theoretical models. Knowledge of particle size and number density is extremely important for accurately predicting heat transfer as well as for environmental considerations. Experimental results are compared to a particle evolution model. A new project involves the application of Fourier transform infrared spectroscopy to on-line measurements of combustion gases, particulates and products of incomplete combustion arising in advanced energy systems and certain manufacturing operations. This work involves optics, the development of algorithms for particle size distribution recovery, and long-pathlength quantitative spectroscopy.
