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: A Challenging European Research Project to Develop New Tiny Microscopes

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.

To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...

Im Focus: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...

Im Focus: Tracing down linear ubiquitination

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.

Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
