Jeffrey T Roberts is the Distinguished McKnight University Professor and Chair of Chemical Physics at the University of Minnesota. The Roberts Group studies surface chemistry at nanometer-sized aerosol particles. The problems studied have applications in a broad range of fields, from the atmospheric sciences to materials chemistry.
Roberts multi-disciplinary work venters on studying chemistry at complex interfaces. For example, looking at a stream of soot particles being emitted into the atmosphere. Where do those particles go? What role do they have in the chemistry of the atmosphere? The group is also exploring how a plasma reactor (used to grow silicon nanoparticles), asking: How can science manipulate the surfaces of those particles to make them stable for device applications? The Roberts Group projects fall into two areas:
- Understanding the reactivity of nanometer-sized atmospheric aerosol particles, such as soot, and
- Developing new ways to deposit materials that have applications in the microelectronics industry.
The work also involves collaborations with scientists and engineers across the University of Minnesota, including Prof. Wayne Gladfelter in the Chemistry Department, Profs. Steve Girshick and Uwe Kortshagen in the Mechanical Engineering Department, and Prof. Stephen Campbell in the Electrical and Computer Engineering Department.

Written by distinguished researchers in carbon, the long-running Chemistry and Physics of Carbon series provides a comprehensive and critical overview of carbon in terms of molecular structure, intermolecular relationships, bulk and surface properties, and their behavior in an amazing variety of current and emerging applications, ranging from nanotechnology to environmental remediation. Volume 30 not only retains the high-quality content and reputation of previous volumes, but also complements them with reliable and timely coverage of the latest advances in the field. The first chapters analyze progressive approaches to controlling more precisely the structure, morphology, and surface properties of novel activated carbons. They cover methods using activating agents such as alkaline hydroxides as well as endo- and exotemplates made from zeolites, silica, and colloidal crystals. The third chapter examines techniques for characterizing carbon surface chemistry,
including electrochemical, spectroscopic, and chromatographic methods. The fourth and final chapter compares the virtues of exfoliated graphite, carbonized fir fibers, carbon fiber felt, and charcoals in solving oil spill problems, a matter of increasing environmental concern. Emphasizing key experimental results, practical aspects, and cutting-edge applications in every chapter, Volume 30 is a vital resource for those developing new technologies such as drug delivery, adsorbents for oil/chemical spills, materials processing, high-performance nanocarbons, and energy storage and conversion devices, including lithium ion batteries, supercapacitors, and fuel cells.
Compound Semiconductors 2004 was the 31st Symposium in this distinguished international series, held at Hoam Convention Center of Seoul National University, Seoul, Korea from September 12 to September 16, 2004. It attracted over 180 submissions from leading scientists in academic and industrial research institutions, and remains a major forum for the compound semiconductor research community since the first one held in 1966 at Edinburgh, UK under the name of 'International Symposium on Gallium Arsenide and related Compounds'.
These proceedings provide an international perspective on the latest research and an overview of recent, important developments in III-V compounds, II-VI compounds and IV-IV compounds. In the total of 106 papers, notable progress was reported in the development of zinc oxide and spintronics. Steady advances were seen in traditional topics such as III-V based electronic and optoelectronic devices, growth and processing, and characterization. Novel research trends were observed in quantum structures, such as quantum wires and dots, which are promising for future developments in nanotechnology. As the primary forum for research into these materials and their device applications the book is an essential reference for researchers working on compound semiconductors in semiconductor physics, device physics, materials science, chemistry and electronic and electrical engineering.
Kattesh Katti, professor of radiology and physics and senior research scientist at the MU Research Reactor, was honored on Tuesday, March 4, with the Outstanding Missourian Award for his work in treating cancer. Katti recently discovered how to make gold nanoparticles using gold salts, soybeans and water – research that has garnered worldwide attention and could have applications in several disciplines.
