New funding from the National Science Foundation and the Water Research Foundation will allow Washington University faculty members to study how to best control lead pipe corrosion.

Washington University researchers awarded $229K to study lead pipe corrosion

The National Science Foundation, along with the Water Research Foundation, has awarded a pair of Washington University in St. Louis researchers $229,000 in grants to study ways to best control lead pipe corrosion, which can poison drinking water. Daniel Giammar, the Walter E. Browne Professor of Environmental Engineering in the School of Engineering & Applied […]

Hot stuff

Numerical models show hot, rocky exoplanets can change their chemistry by vaporizing rock-forming elements in steam atmospheres that are then partially lost to space.
An artist's view showing the control of the emission direction of lasing at exceptional points in a whispering gallery mode microlaser. The tori and the spheres represent the microtoroid resonators and the scatterers, respectively. With two scatterers with appropriate sizes and locations in the field of the resonator, light is emitted in only one direction. The lasing is bidirectional when there is one or no scatterer.

Giving photons their marching orders

Researchers in the School of Engineering & Applied Science have found a way to give photons, or light packets, their marching orders. The researchers have capitalized on the largesse of an energy state in an optical field to make photons in their lasing system travel in a consistent mode, either clockwise or counterclockwise.

XMT 2016: World’s top memory athletes to compete June 24-26

Two dozen of the world’s best memory athletes will battle head-to-head for their share of $75,000 prize money as the Extreme Memory Tournament (XMT-2016) returns to  the headquarters of San Diego-based Dart NeuroScience June 24-26. Sponsored by Washington University in St. Louis and  Dart NeuroScience, the live-streamed competition offers the internet public a chance to […]
Climatic cycles of ice and dust build the Martian polar caps, season by season, year by year, and periodically whittle down their size when the climate changes.

Wandering ice on Mars

Glaciations on Mars are different from those on Earth. During a Martian glacial period, water vapor that would otherwise travel to the north polar cap instead snows out at lower latitudes, where ice then accumulates. Radargrams of the north polar region of Mars record the most recent mid-latitude Martian glacial period and the regrowth of the polar ice since then.

Five-cent chemistry

The research team of Liviu Mirica, associate professor of chemistry in Arts & Sciences, has developed novel methods for generating the buildings blocks of important compounds with the common metal nickel. The work expands scientists’ toolbox for nickel-based chemistry, and contributes to the movement of “green chemistry” toward a 21st century of sustainable synthesis.
