Howard was a long-time member of the ChBE Department, working as a Research Professor since 1998, and serving as Acting Chair from 2001-2002.
Howard received his Ph.D. degree in physical chemistry from Boston University in 1955. After working as a scientist in both private industry and national laboratories, he served as a professor of chemical engineering at University of Rochester for more than 20 years.
While at Tufts, he collaborated with Professor Maria Flytzani-Stephanopoulos and helped advise more than 10 doctoral students.
He is survived by his wife Iris, and his children Debbie and Daniel.

Asatekin Wins NSF CAREER Award

Ayse Asatekin, Assistant Professor, Chemical and Biological Engineering

Assistant Professor Ayse Asatekin received an NSF CAREER Award for her proposal to engineer novel membranes with new capabilities by designing polymers that self-assemble to form nanostructures. Membrane filtration is energy efficient, simple, scalable, and a key technology for generating clean, safe water and for preventing water pollution. Asatekin’s research focuses on controlling the pore size of a novel family of membranes with high flux, exceptional fouling resistance, and sharp size-based selectivity, prepared by coating zwitterion-containing amphiphilic copolymers on porous supports.

Professor Maria Flytzani-Stephanopoulos delivered the L.K. Doraiswamy Honor Lecturer at Iowa State University College of Engineering.

The L.K. Doraiswamy Honor Lectureship in Chemical Engineering selects one internationally recognized scientist or engineer each year to present lectures at Iowa State University and at the National Chemical Laboratory in Pune, India, the home of Doraiswami. The late Dr. Doraiswami was a faculty member of the Department of Chemical and Biological Engineering at Iowa State from 1989 to 2011 and was an Anson Marston Distinguished Professor in Engineering.

Flytzani-Stephanopoulos presented “Heterogeneous Catalyst Design at the Single Atom Limit: A Diverse Reaction Landscape.” Her pioneering research work focuses on understanding metal-metal and metal-oxide interactions at the atomic scale to guide processes for hydrogen and chemical production, and to maximize yields of desired products while using only trace amounts of expensive metals.

Pennell Comments on Metabolomics Methods and the ‘Exposome’ in CE&N

Kurt D. Pennell

In an article in Chemical and Engineering News, Professor and Chair Kurt Pennell commented on how research in metabolomics methods can help address the “exposome”: the sum of environmental exposures a person experiences from conception until death. “Pennell’s goal is to relate exposome information to genetic information. In one study, his group is collaborating with researchers at Children’s Hospital in Boston to relate chemical exposure and whole-genome sequencing of mothers and children with autism spectrum disorder.”

Tufts Names 2015 Summer Scholars

Tufts Summer Scholars program announced the 2015 Summer Scholars.

The Tufts Summer Scholars Program is funded by the Office of the Provost and by generous gifts from: Mr. Andrew Bendetson in honor of Laura and Martin Bendetson; Steven J. Eliopoulos A89 and Joyce J. Eliopoulos; Mr. George and Ms. Susan Kokulis; Mr. John L. Kokulis; Ms. Ashleigh Nelson; and the Board of Trustees in honor of former Chairman, Mr. Nathan Gantcher.

The Program is also supported by the Schwartz-Paddock Family Fellowships in the Visual and Performing Arts, the Helen and Werner Lob Student Research Fund in Economics, the Hopkins Summer Scholar Fund, and the Christopher Columbus Discovery Summer Scholarships for research spanning disciplinary boundaries. Summer Scholars is administered by the Office of Undergraduate Education.

Tufts Softball One Win from NCAA Finals

Allyson Fournier, ChBE 15

Senior CF Michelle Cooprider went 4 for 4 with four runs scored and two rbis as the top-ranked Tufts Softball team earned an 8-0 five-inning victory over WPI in game one of the NCAA Championship Super Regionals Thursday at Spicer Field.

Softball Championship ChBE Senior Allyson Fournier pitched a three-hit shutout for the Jumbos, who are now one win away from making their fourth straight trip to the NCAA Finals.

Fournier improved to 29-0 with the win, striking out 11 along the way. The Jumbos extended their NCAA Division III record winning streak to 47 games while improving to 45-0 this season. WPI dropped to 34-10.

New Catalysts May Provide Path to Low-Cost Production of Future Fuels

New catalysts designed by Tufts University School of Engineering researchers and collaborators from other university and national laboratories have the potential to greatly reduce processing costs in future fuels, such as hydrogen. The catalysts, composed of single gold atoms bound by oxygen to sodium or potassium atoms and supported by a wholly unique structure comprised of non-reactive silica materials, demonstrate comparable activity and stability with current catalysts used in producing highly purified hydrogen.

The work, which appears in Science Express, points to new avenues for producing single-site supported gold catalysts that could produce high-grade hydrogen for cleaner energy use in fuel-cell powered devices, including vehicles.

“In the face of precious metals scarcity and exorbitant fuel-processing costs, these systems are promising in the search for sustainable global energy solutions,” says senior author Maria Flytzani-Stephanopoulos, the Robert and Marcy Haber Endowed Professor in Energy Sustainability.

The paper appeared in the November 27 edition of Science Express. (doi:10.1126/science.1260526). This research is primarily supported by the U.S. Department of Energy under grant # DE-FG02-05ER15730.
