The research team, led by Dr. Reza Zoughi, the Schlumberger Distinguished Professor of Electrical Engineering at Missouri S&T, has developed a patented handheld camera that uses millimeter and microwave signals to non-intrusively peek inside materials and structures in real time. His contributions to this field, in part, have earned him the 2011 Joseph F. Keithley Award in Instrumentation and Measurement from the Institute of Electrical and Electronics Engineers (IEEE).
“In the not-so-distant future, the technology may be customized to address many critical inspection needs, including detecting defects in thermal insulating materials that are found in spacecraft heat insulating foam and tiles, space habitat structures, aircraft radomes and composite-strengthened concrete bridge members,” Zoughi says.
The technology could help medical professionals detect and monitor a variety of skin conditions in humans, including cancer and burns. It also has the potential to help Homeland Security personnel detect concealed contraband (such as weapons) or reduce the number of passenger pat downs at airports. Even homeowners could see a direct benefit from the technology as it potentially could be used to detect termite damage.
“Unlike X-rays, microwaves are non-ionizing and may only cause some heating effect,” Zoughi says. “However, the high sensitivity and other characteristics of this camera enables it to operate at a low-power level.”
The idea for developing a real-time, portable camera came to Zoughi in 1998 while he was on sabbatical in France. In 2007, Zoughi's research group completed the first prototype and has spent the past three years decreasing its size, while improving its overall efficiency.
Currently the camera operates in the transmission mode, meaning objects must pass between a transmitting source and its collector to be reviewed. The team is working on designing and developing a one-sided version of it, which will make it operate in a similar fashion to a video camera.
“Further down the road, we plan to develop a wide-band camera capable of producing real-time 3-D or holographic images,” Zoughi adds.
In 2010, a U.S. patent was issued for this technology. Included on the patent along with Zoughi are Dr. Mohamed Ahmed AbouKhousa, who received a Ph.D. in electrical engineering from Missouri S&T in 2009; Dr. Mohammed Tayeb Ahmad Ghasr, assistant research professor of electrical and computer engineering at Missouri S&T; Dr. Sergiy Kharkivskiy, associate research professor of electrical and computer engineering at Missouri S&T; and Dr. David Pommerenke, professor of electrical and computer engineering at Missouri S&T.

Plants and algae use the enzyme Rubisco to fix carbon dioxide, removing it from the atmosphere and converting it into biomass. Algae have figured out a way to increase the efficiency of carbon fixation. They gather most of their Rubisco into a ball-shaped microcompartment called the pyrenoid, which they flood with a high local concentration of carbon dioxide. A team of scientists at Princeton University, the Carnegie Institution for Science, Stanford University and the Max Plank Institute of Biochemistry have unravelled the mysteries of how the pyrenoid is assembled. These insights can help to engineer crops that remove more carbon dioxide from the atmosphere while producing more food.

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.
The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.
Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
