Dr. Gregory Kubas Selected AAAS Fellow
Dr. Gregory Kubas, a Chemistry Division employee in C-SIC, has been selected as Fellow in the American Association for the Advancement of Science (AAAS). Kubas has long been acknowledged as a gifted inorganic chemist, and he is known throughout the world for his discovery and characterization of transition metal complexes containing chemically bound hydrogen molecules (H2). Unlike in metal hydrides, H2 gas can be reversibly added or removed from the solid complexes at ordinary temperatures and pressures, an important feature for future hydrogen fuel systems.
According to Alfred Sattelberger, former Chemistry Division leader and an AAAS fellow himself, “Before 1984, no one would have believed, let alone predicted, that H2 complexes would be stable relative to free H2 or metal dihydrides. Greg’s discovery fulfills one of the most important criteria for a significant advance – it has changed the way people think.”
Because of this discovery, Kubas is recognized as the founder of an entire field of research, a distinction that few others can claim. In 2001, Kubas published a monograph entitled Metal Dihydrogen and Sigma-Bond Complexes: Structure, Theory, and Reactivity (Kluwer Academic/Plenum Publishers, August 1, 2001). The monograph, which has quickly become the field standard, describes Kubas' discovery of dihydrogen coordination and the study of its structure and general properties. It also looks at both the theory and experimental results of bonding and activation of dihydrogen on metal centers.
As a Fellow, Kubas joins an elite group of the nation's leading researchers educators and policy-makers in all fields of science. He will be honored this coming February during the AAAS Fellows Forum, which is part of the organization's annual meeting. Kubas graduated from Northwestern University in Evanston, IL, in 1970 with a Ph.D. in inorganic chemistry. After arriving at Los Alamos in1972 as a postdoc, he became a technical staff member and was appointed as a Laboratory Fellow in 1987.
AAAS is a nonprofit professional society dedicated to the advancement of scientific and technological excellence across all disciplines, and to the public's understanding of science and technology. AAAS membership comprises more than 134,000 scientists, engineers, science educators, policymakers and other professionals worldwide.
The Kubas Complex, W(CO)3(P-i-Pr3)2(H2), which shows that hydrogen can bind to transition metal complexes, has been called the most important development in inorganic chemistry in the last 20 years. Other research highlights.
