Iowa student engineers develop hand-held water sanitizer for a thirsty world

17.02.2009
What do you do when you learn that about one-sixth of the world's population -- nearly one billion people, according to UNICEF -- lack clean water on a daily basis?

If you happen to be one of 15 student engineers at the University of Iowa, you roll up your sleeves and design a $5, hand-held device to sanitize water and potentially save lives.

Although the student invention began as a class project, it has since become a U.S. Environmental Protection Agency (EPA) first-place-award-winning project (2008 P3 Awards) and the subject of a presentation on Saturday, Feb. 14, at the 2009 Annual Meeting of the American Association for the Advancement of Science (AAAS) in Chicago.

Craig Just, faculty advisor to the UI College of Engineering chapter of the organization Engineers for a Sustainable World and AAAS presenter, said that the EPA award represents an honor for the students and much more for citizens in developing countries.

"We have some of the best students on the planet here at Iowa, and winning the competition was only the beginning," he said. "We hope to multiply the $75,000 first-place award 10-fold in the coming year so that we can make a substantial human health impact in our target countries."

So far, Just and his students have worked with residents of Xicotepec, Mexico. They plan to make water sanitizers available in Ghana and other developing countries in the future.

"I've spoken with a potential industrial partner, a worldwide distributor of chlorine generators designed for pools and spas, that is interested in the effort. These types of partnerships could greatly expand the reach of the project," Just said.

Just's talk, titled "More Affordable Handheld Water Sanitizers," was part of a AAAS session on "Thirsting for Daily Sustenance: Public-Private Partnerships for Global Water Access." Usha R. Balakrishnan of the non-profit organization CARTHA (www.cartha.org) organized the session.

Craig Just, adjunct assistant professor of civil and environmental engineering and associate research scientist at IIHR-Hydroscience & Engineering, was recently appointed coordinator of sustainability programs in the UI College of Engineering. In addition to sustainability assignments in teaching, research, and service within the College, Just works with others on campus associated with UI President Sally Mason's sustainability initiatives.

Just brings a wealth of talent and experience to his coordinator of sustainability assignment. In 2008, he won the University's President and Provost Award for Teaching Excellence in recognition of his years of outstanding teaching.

Im Focus: The working of a molecular string phone

Researchers from the Department of Atomically Resolved Dynamics of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg, the University of Potsdam (both in Germany) and the University of Toronto (Canada) have pieced together a detailed time-lapse movie revealing all the major steps during the catalytic cycle of an enzyme. Surprisingly, the communication between the protein units is accomplished via a water-network akin to a string telephone. This communication is aligned with a ‘breathing’ motion, that is the expansion and contraction of the protein.

This time-lapse sequence of structures reveals dynamic motions as a fundamental element in the molecular foundations of biology.

Im Focus: Milestones on the Way to the Nuclear Clock

Two research teams have succeeded simultaneously in measuring the long-sought Thorium nuclear transition, which enables extremely precise nuclear clocks. TU Wien (Vienna) is part of both teams.

If you want to build the most accurate clock in the world, you need something that "ticks" very fast and extremely precise. In an atomic clock, electrons are...

Im Focus: Graphene sets the stage for the next generation of THz astronomy detectors

Researchers from Chalmers University of Technology have demonstrated a detector made from graphene that could revolutionize the sensors used in next-generation space telescopes. The findings were recently published in the scientific journal Nature Astronomy.

Beyond superconductors, there are few materials that can fulfill the requirements needed for making ultra-sensitive and fast terahertz (THz) detectors for...

Im Focus: Physicists from Stuttgart prove the existence of a supersolid state of matte

A supersolid is a state of matter that can be described in simplified terms as being solid and liquid at the same time. In recent years, extensive efforts have been devoted to the detection of this exotic quantum matter. A research team led by Tilman Pfau and Tim Langen at the 5th Institute of Physics of the University of Stuttgart has succeeded in proving experimentally that the long-sought supersolid state of matter exists. The researchers report their results in Nature magazine.

In our everyday lives, we are familiar with matter existing in three different states: solid, liquid, or gas. However, if matter is cooled down to extremely...

Im Focus: World record for tandem perovskite-CIGS solar cell

A team headed by Prof. Steve Albrecht from the HZB will present a new world-record tandem solar cell at EU PVSEC, the world's largest international photovoltaic and solar energy conference and exhibition, in Marseille, France on September 11, 2019. This tandem solar cell combines the semiconducting materials perovskite and CIGS and achieves a certified efficiency of 23.26 per cent. One reason for this success lies in the cell’s intermediate layer of organic molecules: they self-organise to cover even rough semiconductor surfaces. Two patents have been filed for these layers.

Perovskite-based solar cells have experienced an incredibly rapid increase in efficiency over the last ten years. The combination of perovskites with classical...
