Dr. Willard Bennett joined NCSU in 1961 as Burlington Professor of Physics. He received his 67th and final patent in 1987 for his work on developing ways to accelerate very dense aggregates of ions to achieve higher energies per ion.

In this tube he produced all of the forms of streams found in space as well as the doughnut-shaped rings of charged particles around the earth later known as, the Van Allen radiation belts. Dr. Willard H. Bennett's was inducted into the National Inventors Hall of Fame in 1991. Bennett was honored for his invention of the Bennett radio frequency mass spectrometer patented in 1955.

Professor Daniel Comins' patents center on methods of making asymmetric DE ring intermediates for the synthesis of camptothecin and camptothecin analogs. He has received eighteen patents for this research. Camptothecin is an antitumor alkaloid, and this new approach to the compound has been used by scientists to prepare potential anti-cancer drugs.
The following is an example of one of Comins' patents.
Intermediates and method of making camptothecin and camptothecin analogs
U.S. Patent Number 5,162,532
These photographs are examples of Prof. Heck's work with spiral crystals and various meteorological instruments including a heat measuring device.
Professor James Martin's patent of Luminescent Copper Aluminum Materials, U.S. Patent Number 5,876,637, concerns a class of materials that are brilliant blue phosphors. The luminescence of these materials is readily and reversibly quenched by small molecules such as CO, benzene, ethylene, and NO, making this material useful as a sensor and gas storage and separation material.
Luminescent copper aluminum halide materials
U.S. Patent Number 5,876,637
U.S. Patent Number 5,885,542
A new family of materials, including several compositions of matter, have been created in which Lewis acidic and redox active metal-halide centers are constructed into microporous frameworks. Based on the structural relationships between SiO2 and ZnCl2 this new family of copper zinc halide materials form direct structural analogs to the widely used microporous aluminosilicate materials described as Zeolites. These microporous materials are formed by growing an inorganic network around a molecular or ionic template to create the cage and channel structures such as those shown. The microporous cage and channel structure provides very high surface areas to support chemical reactivity, making them valuable as catalyst materials. Furthermore, molecular and ionic templates create pores in the crystalline structures of molecular dimensions, so these microporous materials can be viewed as molecular-sized reaction chambers that induce a size and shape selectivity to chemical reactions. By constructing such frameworks out of reactive metal-halides (CuCl, ZnCl2 , and AlCl3) instead of the more stable oxides (SiO2 and Al2O3, the components of many rocks), new chemical reactivity of microporous frameworks can be achieved. Varied syntheses of these metal-halide framework materials result in the formation of nano-scale dispersions. Alternatively, glassy preparations of the templated networks exhibit birefringent optical properties.
