Chamber reveals chemical secrets

02.06.2003



What if there were a magical chamber that could divulge the secrets of anything that was placed inside of it? Pacific Northwest National Laboratory has developed such a chamber—and while it won’t divulge all secrets, it discloses key information about chemicals and compounds.

That information may be useful in addressing a wide range of issues that affect the environment and quality of life—everything from sick building syndrome and industrial emissions monitoring and control to sensor testing for homeland security applications.

PNNL’s chamber, known as the Atmospheric Research Chamber, was developed in 2002. The chamber concept can be traced to PNNL’s work in fate and transport studies, which revealed that there is still much to learn about how chemicals react in the environment.



The chamber actually is a large, room-sized set of dual chambers that analyzes chemical mixtures by subjecting the material to an assortment of tests. These tests, for example, characterize unknown chemical substances; expose chemicals to photo-oxidation or high humidity to mimic what might actually happen in the environment; and effectively monitor aerosols and molds. In addition, the chamber can be used to calibrate sensitive sensors or detectors for interferences like dusts, oils or other chemicals.

Teflon-lined and containing ultraviolet lights, reflective surfaces, sampling and purge ports, stirring fans and state-of- the-art analysis equipment, the chamber also provides information that could be used for determining chemical and/or biological sensor detection issues and validating computational modeling by performing actual experiments that can be done without expensive field tests. The chamber is able to measure high-boiling point, semivolatile chemicals without critical surface and line losses, shed new light on air pollution and health issues for civilian and military populations and provide improved understanding of hazardous waste discharges for more effective cleanup solutions.

"With the chamber’s unique ability to work with semi-volatile chemicals and its powerful analytical capabilities, we feel that it can serve the needs of many different clients who would not be able to find the same capabilities elsewhere," said Kathy Probasco, senior research scientist. Probasco added the chamber’s capabilities are now available to external clients and projects.

Im Focus: New double-contrast technique picks up small tumors on MRI

Early detection of tumors is extremely important in treating cancer. A new technique developed by researchers at the University of California, Davis offers a significant advance in using magnetic resonance imaging to pick out even very small tumors from normal tissue. The work is published May 25 in the journal Nature Nanotechnology.

Im Focus: I-call - When microimplants communicate with each other / Innovation driver digitization - "Smart Health“

Microelectronics as a key technology enables numerous innovations in the field of intelligent medical technology. The Fraunhofer Institute for Biomedical Engineering IBMT coordinates the BMBF cooperative project "I-call" realizing the first electronic system for ultrasound-based, safe and interference-resistant data transmission between implants in the human body.

When microelectronic systems are used for medical applications, they have to meet high requirements in terms of biocompatibility, reliability, energy...

Im Focus: When predictions of theoretical chemists become reality

Thomas Heine, Professor of Theoretical Chemistry at TU Dresden, together with his team, first predicted a topological 2D polymer in 2019. Only one year later, an international team led by Italian researchers was able to synthesize these materials and experimentally prove their topological properties. For the renowned journal Nature Materials, this was the occasion to invite Thomas Heine to a News and Views article, which was published this week. Under the title "Making 2D Topological Polymers a reality" Prof. Heine describes how his theory became a reality.

Ultrathin materials are extremely interesting as building blocks for next generation nano electronic devices, as it is much easier to make circuits and other...

Im Focus: Rolling into the deep

Scientists took a leukocyte as the blueprint and developed a microrobot that has the size, shape and moving capabilities of a white blood cell. Simulating a blood vessel in a laboratory setting, they succeeded in magnetically navigating the ball-shaped microroller through this dynamic and dense environment. The drug-delivery vehicle withstood the simulated blood flow, pushing the developments in targeted drug delivery a step further: inside the body, there is no better access route to all tissues and organs than the circulatory system. A robot that could actually travel through this finely woven web would revolutionize the minimally-invasive treatment of illnesses.

A team of scientists from the Max Planck Institute for Intelligent Systems (MPI-IS) in Stuttgart invented a tiny microrobot that resembles a white blood cell...

Im Focus: NASA's Curiosity rover finds clues to chilly ancient Mars buried in rocks

By studying the chemical elements on Mars today -- including carbon and oxygen -- scientists can work backwards to piece together the history of a planet that once had the conditions necessary to support life.

Weaving this story, element by element, from roughly 140 million miles (225 million kilometers) away is a painstaking process. But scientists aren't the type...
