The Best of Both Catalytic Worlds

Berkeley Lab Researchers Develop New Technique for Heterogenizing Homogenous Nano Catalysts

Catalysts are substances that speed up the rates of chemical reactions without themselves being chemically changed. Industrial catalysts come in two main types – heterogeneous, in which the catalyst is in a different phase from the reactants; and homogeneous, in which catalyst and the reactants are in the same phase. Heterogeneous catalysts are valued for their sustainability because they can be recycled. Homogeneous catalysts are valued for their product selectivity as their properties can be easily tuned through relatively simple chemistry.

Researchers with the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab) have combined the best properties of both types of industrial catalysts by encapsulating nanoclusters of a metallic heterogeneous catalyst within the branched arms of the molecules known as dendrimers.

State-Mandated Planning, Higher Resident Wealth Linked to More Sustainable City Transportation

Environment

COLUMBUS, Ohio – Transportation practices tend to be more environmentally friendly in wealthier metropolitan areas located within states that mandate comprehensive planning, new research suggests.

The study involved an examination of 225 U.S. metropolitan areas between 1980 and 2008 to gauge how sustainable their transportation practices were and determine what kinds of socioeconomic factors appeared to influence those practices. (more…)

Taubman Center Survey: RI Voters Likely to Approve Casino Gambling

Politics

A new Brown University poll of Rhode Island voters finds strong support for state-operated casino gaming at Twin River and Newport Grand. In the hotly contested Congressional District One race, Rep. David Cicilline retains a small lead. The survey, conducted Sept. 26 to Oct. 5 2012, is based on a sample of 496 registered voters in Rhode Island.

PROVIDENCE, R.I. [Brown University] — A new public opinion survey by Brown University researchers finds that Rhode Island voters appear poised to approve questions one and two on the state ballot, which would allow casino gaming in Lincoln and Newport. Despite an approval rating of just 29.7 percent, Rep. David Cicilline appears to have an edge over Republican challenger Brendan Doherty among voters in 1st Congressional District.

Researchers at the A. Alfred Taubman Center for Public Policy and American Institutions and the John Hazen White Public Opinion Laboratory at Brown University surveyed a random sample of 496 Rhode Island voters from Sept. 26 to Oct. 5, 2012. The poll has an overall margin of error of plus or minus 4.4 percent. (more…)

Freezing Electrons in Flight

Science

Using the world’s fastest laser pulses, which can freeze the ultrafast motion of electrons and atoms, UA physicists have caught the action of molecules breaking apart and electrons getting knocked out of atoms. Their research helps us better understand molecular processes and ultimately be able to control them in many possible applications

In 1878, a now iconic series of photographs instantly solved a long-standing mystery: Does a galloping horse touch the ground at all times? (It doesn’t.) The images of Eadweard Muybridge taken alongside a racetrack marked the beginning of high-speed photography. (more…)

Mug Handles Could Help Hot Plasma Give Lower-Cost, Controllable Fusion Energy

Science

Researchers around the world are working on an efficient, reliable way to contain the plasma used in fusion reactors, potentially bringing down the cost of this promising but technically elusive energy source. A new finding from the University of Washington could help contain and stabilize the plasma using as little as 1 percent of the energy required by current methods. (more…)

Breaking a Genocide’s Silence: Rwandan Storytelling Exhibit Centerpiece of New National Archives

ANN ARBOR — One of the casualties of the 1994 Rwandan genocide was the culture’s storytelling tradition. Resurrecting it has been the mission of a project called Stories for Hope for the past four years. (more…)

Tiny Cloud Droplets

Science

UD’s Wang contributes invited paper on cloud microphysics

Lian-Ping Wang, professor of mechanical engineering and joint professor of physical ocean science and engineering at the University of Delaware, recently published an invited critical review paper in the 2013 volume of the Annual Review of Fluid Mechanics, a high impact journal for the fluid mechanics community.

Co-authored with Wojciech Grabowski, a senior scientist from the National Center for Atmospheric Research (NCAR), the paper, titled “Growth of Cloud Droplets in a Turbulent Environment,” addresses a classic cloud physics problem of how cloud turbulence affects the growth of tiny cloud droplets.
