  • Photo: Trisha Andrew Save power, make power: UW chemist confronts ambitious agenda with a brash laugh Nov. 25, 2014
  • Photo: Lump of fool's gold Scientists get to the heart of fool's gold as a solar material Nov. 18, 2014 As the installation of photovoltaic solar cells continues to accelerate, scientists are looking for inexpensive materials beyond the traditional silicon that can efficiently convert sunlight into electricity.
  • Photo: Shannon Stahl New process transforms wood, crop waste into valuable chemicals Nov. 3, 2014 Scientists today disclosed a new method to convert lignin, a biomass waste product, into simple chemicals. The innovation is an important step toward replacing petroleum-based fuels and chemicals with biorenewable materials, says Shannon Stahl, an expert in "green chemistry" at the University of Wisconsin-Madison.
  • Photo: Shannon Stahl Professor honored for green chemistry research Oct. 20, 2014 University of Wisconsin-Madison chemistry professor Shannon Stahl is one of five scientists nationwide to receive a Presidential Green Chemistry Challenge Award from the U.S. Environmental Protection Agency (EPA) in recognition of his research on using oxygen from the air in chemical reactions.
  • Photo: Trisha Andrew UW-Madison chemist named Packard Fellow Oct. 16, 2014 Trisha Andrew, a University of Wisconsin-Madison assistant professor of chemistry, is one of 18 early career scientists from around the country named a Packard Fellow for Science and Engineering. The award includes a grant of $875,000 over five years to pursue research and is given in recognition of the potential significance of scholarship and innovation from the nation’s most promising young scientists and engineers.
  • Sigma-Aldrich employees partner with SCIENCountErs program Oct. 2, 2014 To provide more opportunities for young people to engage in science, the University of Wisconsin-Madison’s Nanoscale Science and Engineering Center (NSEC) and Institute for Chemical Education (ICE) have partnered on a wide range of science outreach programs. The effort was recently bolstered by a new three-year partnership with Sigma-Aldrich, a global life sciences and technology company based out of St. Louis, Missouri, with facilities in Madison and Milwaukee.
  • Helen Blackwell Researchers study vital 'on/off switches' that control when bacteria turn deadly Sept. 18, 2014 No matter how many times it’s demonstrated, it’s still hard to envision bacteria as social, communicating creatures. But by using a signaling system called “quorum sensing,” these single-celled organisms radically alter their behavior to suit their population. Helen Blackwell, a professor of chemistry at the University of Wisconsin-Madison, has been making artificial compounds that mimic the natural quorum-sensing signals, including some that block a natural signal from binding to its protein target.
  • Neuron In directing stem cells, study shows context matters Sept. 8, 2014 In a new study, a team of researchers from the University of Wisconsin-Madison has added a new wrinkle to the cell differentiation equation, showing that the stiffness of the surfaces on which stem cells are grown can exert a profound influence on cell fate.
  • Manos Mavrikakis Water’s reaction with metal oxides opens doors for researchers Aug. 8, 2014 A multi-institutional team has resolved a long-unanswered question about how two of the world’s most common substances interact. In a paper published recently in the journal Nature Communications, Manos Mavrikakis, professor of chemical and biological engineering at the University of Wisconsin-Madison, and his collaborators report fundamental discoveries about how water reacts with metal oxides
  • Photo: Shakhashiri fireworks demonstration ‘Science is fun’ offers traditional July Fourth show July 1, 2014 Chemist and stage master Bassam Shakhashiri will present “Science and Fireworks: Sights and Sounds for Independence Day,” on the Memorial Union Terrace July 4.
  • Photo: Sam Gellman Chemical strategy hints at better drugs for osteoporosis, diabetes June 16, 2014 By swapping replacement parts into the backbone of a synthetic hormone, UW-Madison graduate student Ross Cheloha and his mentor Sam Gellman, along with collaborators at Harvard Medical School, have built a version of a parathyroid hormone that resists degradation in laboratory mice. As a result, the altered hormone can stay around longer - and at much higher concentration, says Gellman, professor of chemistry at the UW.
  • Photo: Jordan Schmidt UW–Madison chemist wins young teacher-scholar award June 10, 2014 Jordan Schmidt, assistant professor of chemistry at the University of Wisconsin–Madison, is one of 15 young researchers to win prestigious 2014 Camille Dreyfus Teacher-Scholar awards.
  • Photo: reactor in window Lighting up the lab: Team harnesses light for controlled chemical reaction April 24, 2014 When chemist Tehshik Yoon looks out his office window, he sees a source of energy to drive chemical reactions. Plants “learned” to synthesize chemicals with sunlight eons ago; Yoon came to the field a bit more recently. But this week, in the journal Science, he and three collaborators detail a way to use sunlight and two catalysts to create molecules that are difficult to make with conventional techniques — a finding that may eventually have implications for drug making and materials science.
  • Photo: Kyoung-Shin Choi New, inexpensive production materials boost promise of hydrogen fuel Feb. 21, 2014 Generating electricity is not the only way to turn sunlight into energy we can use on demand. The sun can also drive reactions to create chemical fuels, such as hydrogen, that can in turn power cars, trucks and trains.
  • Photo: Joshua Shutter Prolific chemistry student wins Churchill Scholarship Feb. 4, 2014 As a child, Joshua Shutter's introduction to chemistry came through library books, learning to make rock candy and bottle rockets.
  • Photo: Rika Khadria Grad student’s proteins cut a rug, win ‘Dance Your Ph.D.’ competition Jan. 14, 2014 Graduate school research can get long and tricky and complex beyond the easy understanding even of your fellow grad students. Unless it has a beat, that is, and you can dance to it.
  • Photo: Martin Zanni New look identifies crucial clumping of diabetes-causing proteins Nov. 11, 2013 People get type 2 diabetes. So do cats. But rats don’t, and neither do dogs. Subtle differences in the shape of proteins protect some and endanger others.
  • Photo: Bassam Shakhashiri UW-Madison chemist named ‘Friend of Education’ Sept. 27, 2013 Bassam Shakhashiri, known far and wide for his annual holiday season exhibitions of chemistry, has been named a "Friend of Education" by the Wisconsin Department of Public Instruction.
  • Photo: catalytic converter Researchers capture speedy chemical reaction in mid-stride Sept. 13, 2013 In synthetic chemistry, making the best possible use of the needed ingredients is key to optimizing high-quality production at the lowest possible cost.
  • Photo: Bill Banholzer Retired Dow exec joins UW, will focus on innovation Sept. 6, 2013 An industry executive who has spent his entire career translating inventions into products that are both profitable and beneficial to society has joined the University of Wisconsin-Madison.
