Engineer helps relieve asthma suffering
Device used to collect analyze air particles that cause pollution
By Robert Allen
Kansan staff writer
Asthma sufferers may breathe easier in the future. The civil engineering department at the University of Kansas is seeking a patent for a device that tests air quality.
Dennis Lane, N.T. Veatch distinguished professor of civil engineering, has invented a device that collects airborne particles smaller than 10 micrometers. One thousand of these tiny particles could fit side by side on the head of a pin. The invention will be used for analyzing air pollution.
"Breathing these particles could trigger asthma in folks that suffer from that condition," he said. "The country needed some kind of device to sort them out."
The human body can trap particles larger than 10 micrometers in the nose and sinuses. Tiny hairs send the foreign objects to the stomach, where they are destroyed.
The department has received more than $500,000 from the Environmental Protection Agency, the National Science Foundation, the Midwest Research Institute and KU, to research and develop the sampling device. The invention could be used to control pollution in industrial areas and to see precisely what people are breathing.
But the body cannot filter out smaller particles, which is where the device comes in.
Lane has been intrigued with this area of research since the 1970s, when he was a graduate student at the University of Illinois.
This device is actually the latest incarnation in a long succession of particle sampling devices Lane has developed. The first of these hand-sized contraptions was made of glass and needed constant attention by a trained technician to be used properly.

Dennis Lane, N,T, Veatch distinguished professor of civil engineering, is working on particle sampling devices that would help relieve asthma sufferers.
"But the EPA wanted something that just screws on and goes," he said.
Lane then developed several more designs made from aluminum and Teflon, which did not require constant care.
"The EPA has taken the devices all over the world," Lane said. "Soviet Russia has a tremendous air pollution problem. They were very interested in what people were being subjected to."
The latest design has some unique features. but
because the patent is pending, Lane would not discuss the specifics of the device. The patent office has a policy of disclosure, Lane said, in which the department has exactly one year to obtain the patent after publication of the invention.
However, Lane described some of the problems he attempted to overcome in the latest design.
"One of several problems is wind direction," he said. "The new one has
a mechanism that allows it to virtually always be pointed into the wind."
Also, the speed at which the device draws air must equal the wind speed, he said. If it is higher, the smaller particles won't be collected.
"That's what made it so interesting and so fascinating." Lane said.
Bob Stevens, chief of the source apportionment research branch of the EPA, said that the agency had a cooperative agreement with the
civil engineering department to develop this device.
"The agency is always interested in important methods in collecting atmospheric particles," he said. "We're like detectives. We collect particles and figure out where they came from."
The EPA chose KU for the job because of the facilities and research previously conducted.
Civil engineering students striving for rock-solid support
"He has done some important work." Stevens said of Lane.

Sidewalks and buildings could become stronger in the future, thanks to the efforts of the civil engineering department at the University of Kansas.
David Darwin, professor of civil engineering, leads a team that is developing a better design for reinforcement bars—steel rods arranged in a crisscross pattern and immersed in concrete. The bars add strength to concrete structures.
"We're taking designs that exist today and making them better." Deygin said.
The National Science Foundation, the Federal
Highway Administration and various industries have given KU more than $700,000 to study reinforcement bars.
Darwin and his team of researchers were studying how the bars actually grip concrete. Designs on the outside of the bars, such as small bumps, can increase the bond between the concrete and the steel.
Eight graduate students and 51 undergraduates have participated in the project. Six of the graduate students have used the study for degree purposes.
KU is well-known for reinforcement bar research, Darwin said.
"If this catches on, the reinforcement bars we use in the U.S. will change," he said.
Using the new designs, the team builds models and tests their strengths, which occasionally breaks them when the pressure is too great.
Mike Tholen, Grinnell graduate student, said he enjoyed working on the project.
"It's more hands-on, not sitting in front of a computer all day," he said. "There aren't too many jobs where you get paid to break things."
Darwin said the team was working on phase one of the project—determining what changes are needed in the bars. In phase two, additional tests will study the behaviors of the bonds.
