Dr. Jacek Dudowicz

Research Professor

Theoretical, statistical thermodynamical studies of liquid state polymers represent an important scientific tool in modern polymer physics. One of our interests lies in predicting the thermodynamic properties of multi-component polymer mixtures, such as phase behavior, miscibility, or neutron scattering intensity as a function of monomer structures, temperature, pressure, and blend composition. Another interest focuses on the equilibrium polymerization that is a paradigm for clustering transitions occurring in numerous systems, ranging from various nano-particle filled materials to proteins in living organisms. An illustrative example of this research is provided by our recent description of the equilibrium polymerization of actin.

Dr. Kevin Drew Gibson

Research Professor

As a member of the Sibener group, my interests involve studying gas-surface interactions. The main tool for these studies is an ultra-high-vacuum chamber that allows us to expose the surface of interest to gases from three independent molecular beams. Reactions at the surface, and the energy, angular distribution, and identity of any scattered or desorbed atom or molecule can be determined. Recent experiments have examined the oxidation of benzene and the translational energy dependence of methane decomposition on Rh(111). We have also studied the surface reactions of atomic O, examining the partial oxidation of adsorbed organic compounds, and the modification of the transition metal surface. The latter allowed us to grow a novel, dense water overlayer. Currently, we are studying the scattering of gases from organic monolayers. Future work will measure the surface reactions of atomic O at high kinetic energies, a problem for objects in low-earth orbit.

His research interests include: (1) Applications of Scanning Probing Microscopy and Scanning Electron Microscopy to materials research. (2) Application of electron beam lithography to materials research. (3) Thermochemistry of intermetallic compounds and mixed oxide systems, using high-temperature reaction calorimetry. (4) Theoretical analysis of topological structures of phase diagrams for systems of n+3 phases (n stands for the number of independent components of the systems), with emphasis on the interrelationship between phase chemography and phase diagram topology. (5) Topological relations in systems of more than n+3 phases. He is also responsible for training students and postdocs for operating SEM, AFM/STM and other MRSEC shared facilities in the MPML.
