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 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.
Congratulations to all our engineering summer scholars!

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 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.
John A. and Dorothy M. Adams Faculty Development Professor Tom Vandervelde received a $1M grant for equipment crucial in the development of solar cells, infrared cameras, high-speed (100+GHz) circuits, lasers, and LED lighting. He received a Major Research Instrumentation award from the National Science Foundation to build a multi-chamber molecular beam epitaxy system, which enables the creation of novel semiconductor materials and devices.
Associate Professor and Chair Kyongbum Lee and colleagues in the Department of Biomedical Engineering received a $338K grant for the acquisitions of a state-of-the-art mass spectrometry (MS) system for a range of metabolomics and proteomics applications. Mass spectrometry has emerged as the technology of choice for workflows seeking to identify, detect, and/or quantify metabolites and other small molecules as well as proteins and peptides in complex biological samples.
Assistant Professor Matthew Panzer of the Department of Chemical and Biological Engineering wrote an “Ask the Expert” piece for TuftsNow on how options for storing solar energy.
“When the sun shines, we can store the electricity generated by solar cells or steam-driven turbines by using batteries (technically energy stored as electrochemical potential) or supercapacitors (energy stored in an electric field, due to the spatial separation of positive and negative charges). Then we can release electrical energy when it is cloudy or at night.
There are at least two other ways to store solar energy for use later. First, the thermal energy of concentrated sunlight can be stored in the heat capacity of a molten salt (the liquid form of an ionic compound like sodium chloride) at a high temperature. When electricity is needed later, heat is transferred from the molten salt to water, using a heat exchanger to generate steam to drive a turbine.”
