News Item UCLA and JPL Develop Spectrometer Chip Based on CMOS Smartphone Technology for Future NASA Instruments

Mau-Chung Frank ChangUCLA faculty Frank Chang in collaboration with NASA Jet Propulsion Lab researchers Adrian Tang, Goutam Chattopadhyay, and Brian Drouin have developed an extremely low-power (less than 0.2 W) wideband spectrometer processor chip capable of detecting trace gases for future NASA instruments. The developed chip uses the same CMOS system-on-chip technology found in smartphones and tablets, allowing the spectrometer processor to be compact, and extremely energy efficient. This efficiency will enable future NASA spectrometer instruments to be flown on much smaller platforms (UAVs and cube satellites) as well as in deep space planetary science missions where power and payload size are extremely limited.

The demonstrated spectrometer chip occupies only 15 cm3 of volume and weighs less than 200 grams while its GHz-wide bandwidth makes it applicable to a wide range of Earth science, planetary science, and astrophysics applications. The single chip contains a wide range of functions including analog amplification and signal conditioning, calibration functions, analog-to-digital conversion, and signal processing to compute detected chemical spectra. UCLA graduate students Rod Kim and Li Du and visiting scholar Frank Hsiao also participated in the development of the spectrometer chip.NASA-JPL-logo




News Item High power terahertz radiation sources developed by Professor Jarrahi’s group are highlighted in the Laser Focus World Magazine

Mona JarrahiWork by Professor Mona Jarrahi’s research group on plasmonic photomixers has been highlighted in the Laser Focus World Magazine.

The team has demonstrated a high-performance source of continuous-wave terahertz radiation that can generate record-high radiation powers with extreme frequency tunability, while operating at room temperature.

This has been achieved by incorporating plasmonic nanostructures into a photomixer to offer significantly higher quantum efficiencies than that of previously demonstrated devices.  Moreover, this device is designed to operate at standard telecommunication optical wavelengths, which can be incorporated into a relatively compact and inexpensive setup.

The principal investigator on the research is Professor Mona Jarrahi and other authors include Christopher Berry, a former student of Jarrahi’s at the University of Michigan, Ann Arbor; Mohammad R. Hashemi, a UCLA post-doctoral scholar; Sascha Preu, Professor of Electrical Engineering and Information Technology at the Technical University of Darmstadt (Germany); Hong Lu, a researcher at UC Santa Barbara; and Arthur C. Gossard, Professor of Materials, Electrical and Computer Engineering at UC Santa Barbara.

Furthermore, it is compatible with IC technology and may be included in mobile devices without increasing manufacturing costs.

Together with Wang, the DMC technology was developed by graduate student Shihan Qin and post-doctoral scholar Qiang Xu. Their research paper was published in the IEEE Transactions on Microwave Theory and Techniques in October 2014.




News Item Grad Student Yufei Mao Presented a Late-Breaking Research at HICPT 2014

Yufei_MaoGrad student Yufei Mao, advisor, Associate Professor Chi On Chui, together with colleague in the Department of Pathology, UCLA-Ronald Reagan Hospital presented a late breaking research paper, entitled, “Validation of Semiconductor Electronic Label-Free Assay (SELFA) for Point-of-Care Cardiac Troponin I Measurement,” at the IEEE EMBS Special Topic Conference on Healthcare Innovation & Point-of-Care Technologies (HICPT'14) in Seattle, WA.

In the work, the SELFA platform was implemented to measure cardiac troponin I (cTnI) in patient specimens, the results demonstrate a highly linear relation with that measured by LOCI® assay at the UCLA clinical laboratory, Ronald Reagan UCLA Medical Center. With a turnaround time within 10-15 minutes, the SELFA platform can be developed to a point-of-care device and be used to quantitatively and accurately measure cTnI in patient specimens for diagnosing myocardial infarction or commonly called as a heart attack.

News Item Asael Papour is Awarded the Dr. Ursula Mandel Scholarship

PapourAsaelAsael Papour, a graduate student under the mentorship of Prof. Oscar Stafsudd, received the UCLA Dr. Ursula Mandel Scholarship for scholastic and research achievements in the medical field. Papour has developed two compact biomedical imaging systems using auto-fluorescence and Raman techniques for intraoperative real-time tissue characterization. These robust technologies can image various tissue abnormalities including cancer tumor margins and serve as an early detection system for bone growth (Heterotopic Ossification) in failed wounds (combat wounds). A paradigm change in fluorescence and Raman optical tissue characterization enabled new research approaches, and removed the hurdles for accepting these technologies in patient care. By using spectroscopy-free fast Raman imaging and auto-fluorescence pulse shaping breakthrough, an unmet clinical need for inexpensive, non-ionizing (x-ray) imaging device is created.

Asael is a member of the Quantum Electronics Laboratory under the supervision of Professor Oscar Stafsudd (Electrical Engineering), and Professor Warren Grundfest (Bioengineering/Electrical Engineering). Asael completed a master’s degree in Electrical Engineering from UCLA in 2012. He received bachelor’s degree in Physics, minor in Chemistry, in 2008 from the Hebrew University of Jerusalem, Israel.

News Item UCLA Researchers Receive $1.29M NSF Grant for Scalable Nanomanufacturing

Chi On ChuiA team of UCLA researchers has received a $1.29 million, four-year grant from the National Science Foundation to explore low-cost methods of manufacturing fibers with unprecedented continuous metal nanowires — a material with potential for ultra high-resolution cellular electrophysiology analysis technologies that could conduct sub-cellular and intracellular measurements down to a single biological cell.
The principal investigators of the research team include Xiaochun Li, Raytheon Professor of Manufacturing and Chi On Chui, associate professor of electrical engineering and bioengineering, both of the UCLA Henry Samueli School of Engineering and Applied Science; and Huan Meng, an adjunct assistant professor of nanomedicine at the UCLA David Geffen School of Medicine.

While there is a great demand for the high-volume production of fibers with continuous metallic nanowires, there has not been a reliable and scalable manufacturing method due to fundamental and technical issues surrounding their nanoscale size. This includes instability of molten metals during thermal drawing of the wires, and difficulties controlling wire formation using traditional manufacturing techniques. The UCLA research team will explore novel approaches to address these barriers to a low-cost, reliable and scalable nanomanufacturing process.

Current cellular electrophysiology analyses are used in high-volume, such as the development of pharmaceuticals, toxicity screenings, and threat detection. Using fibers with continuous nanowires as narrow as just tens of nanometers in diameter would enable high resolution analytical platforms, which could examine a single to few biological cells at a time. The resultant platforms could measure cellular events that, for example, indicate the presence of cancer cells, earlier than current technologies can. Specifically, the researchers and their students will explore theoretical materials and functional designs for nanoelectrode arrays; scalable nanomanufacturing of fibers with metal nanowires through thermal drawing; observation and characterization of nanoelectrode arrays; and development and validation of nanoelectrode-enabled cell-based assay platforms.

Other potential technologies for this include high-resolution semiconductors and metamaterials characterizations, and neural and cardiac electrical signal recorders.NSF
