texas a&m university is one of six core partners in a new multi-million-dollar national science foundation (nsf) center expected to revolutionize sensor technology and yield devices capable of transforming aspects of various industries ranging from health care to environmental quality the center dubbed mirthe for mid-infrared technologies for health and the environment is part of the nsfs recently unveiled 2006 class of engineering research centers (ercs) which are among the foundations largest and most prestigious grants launched may 1 with $15 million in nsf funding over five years mirthe is expected to attract additional financial support from corporate partners and other sources to conduct more than $40 million in research and educational activities during the next 10 years mirthe will be housed at princeton university and led by claire gmachl associate professor of electrical engineering at princeton the center will combine the work of about 40 faculty members 30 graduate students and 30 undergraduates from the six core partner institutions which also include the university of maryland-baltimore county rice university johns hopkins university and the city college of new york as multiple-institution partnerships the centers foster collaboration among researchers from many disciplines and provide rich educational and research environments for preparing new generations of engineering leaders says lynn preston nsf deputy division director for centers in addition to collaborating with dozens of industrial partners to turn their resulting technology into commercial products mirthe will work with several educational outreach partners which will use the centers research as a vehicle for improving science and engineering education at the k-12 and college levels to help ensure a more knowledgeable and competitive us workforce this center allows the texas a&m college of science to enhance several of our most important initiatives including collaborative research and educational outreach adds h joseph newton dean of the college of science mirthes work will span fundamental science to applied technology for example one avenue of research is to develop devices that allow doctors to diagnose and monitor diseases including lung kidney and liver disorders by measuring chemicals in a patients breath other mirthe participants will explore highly sensitive low-cost sensors that monitor air quality follow the evolution of greenhouse gases in the atmosphere or detect chemical weapons the sensors we are creating will be portable and easy to use gmachl explains todays state-of-the-art sensors are very sensitive but they require an expert to operate and are bulky and expensive mirthes vision is to make sensors with the same or better level of sensitivity at a fraction of the size and cost a key technology enabling the centers work is the quantum cascade laser named for the way the electrons cascade through thin layers of material stacked within the device the major advantage of these lasers is that they emit light in the part of the spectrum known as the mid-infrared the area where most molecules have strong spectral fingerprints gmachl says having the ability to produce and detect these wavelengths allows scientists to see certain chemicals in the same way that sunlight and the human eye reveal everyday objects texas a&ms mirthe team includes groups led by physics professors alexey belyanin marlan scully and michael weimer as well as electrical engineering professor christi madsen belyanin and scully will attack several problems that hinder the development of mid-infrared sensor technologies including ways to improve sensitivity of the detectors using the same kind of physics that previously enabled texas a&m physicists to slow light to tens of meters per second imagine that you are standing near a roaring airplane engine and trying to listen to a soft whisper while wearing headphones that play loud music belyanin explains our goal is to detect a weak mid-infrared signal from a tiny amount of chemicals amid a huge background of thermal radiation produced by all surrounding objects including the body of the detector itself one additional problem is how to scan the laser through signals produced by different molecules which belyanin equates to searching for a particular radio stations frequency by turning a knob during the past decade weimers laboratory has pioneered new techniques for visualizing the detailed atomic arrangements at the heart of such lasers and detectors that in turn control the precise frequencies or wavelengths emitted or absorbed by these structures we are especially excited by this unparalleled opportunity to pursue the challenging and significant scientific questions naturally brought up by visionary applications of such societal importance weimer adds madsen will focus on designing and fabricating integrated optical components to make a spectrometer-on-a-chip when combined with the laser and detector work of other groups it will enable compact and affordable analysis of the mid-infrared signature of materials for environmental health
