Scientists Measure Speedy Electrons In Silicon
The entire semiconductor industry, not to mention Silicon Valley, is built on the propensity of electrons in silicon to get kicked out of their atomic shells and become free. These mobile electrons are routed and switched though transistors, carrying the digital information that characterizes our age. By Robert Sanders
UNSW Researchers Set World Record In Solar Energy Efficiency
UNSW's solar researchers have converted over 40% of the sunlight hitting a solar system into electricity, the highest efficiency ever reported.
Can Optogenetics Help Treat Epilepsy?
Using gene therapy techniques, researchers at the University of California Irvine (UC Irvine) have developed an optogenetic approach that allows them to monitor neuronal activity during and in between seizures. The new approach enables interactions with a single cell or entire networks of cells, and it could lead to the development of new therapeutic approaches for epilepsy.

4 Electronic Design Requirements Of The System-Integrated Soldier
Perhaps most famously portrayed in Robert Heinlein’s Starship Troopers (1959), the idea of the “future soldier” has been around for decades. As rehashed in countless science fiction films and video games, the stereotypical future soldier is equipped with a protective exoskeleton, enhanced sensory equipment, seamless communication systems, and advanced weaponry. While the concept once seemed implausible, there are many real-world projects under way focused on realizing those seemingly fictitious warfighter capabilities — by integrating a plethora of diverse electronic subsystems into a cohesively operational suit.
The Top 5 Technologies From DSS 2014
With more than 450 companies at this year’s event and only three days to explore, it was an almost overwhelming task to try and take in all of the technology on display. Regardless, I did my best, and here is my list of the top five most exciting technologies I caught at the show.
Ladybug Takes Off In Slow Motion
This particular sequence was recorded with at pco.dimax HD CMOS camera at 3,000 frames-per-second and 1296 x 720 pixel resolution. Once the ladybug unfolds its wings, the display speed is reduced to 25 fps.
Clear, Colored Images Captured In Low Light
This video was taken out of a lab window at dawn. The sequence displays three times at 16bit and 8bit scaling to capture details. All imagery was captured by the pco.edge – a color, sCMOS (scientific CMOS) camera operating at 2560 x 2160 resolution at 100 frames/s.
Fishing Kingfisher in Slow Motion II
The pco.dimax HD is a high-speed, 12-bit CMOS camera ideal for a variety of slow-motion capture applications. In this video example, Rainer Bergomaz from Blue Paw Artists used one of these cameras with 1920 x 1440 pixel resolution @ 1060 frames/s to capture sequences of young kingfishers trying (successfully, in some instances) to catch fish.
Magic Drops In Slow Motion
Blue Paw Artists’ Rainer Bergomaz and Daniel Nimmervoll used the pco.dimax HD high-speed camera to capture water droplet sequences, showing that slow motion imagery is just as appealing aesthetically as it is scientifically.
Tracking Objects Through Heat Signature Acquisition
This video showcases an ATP (acquisition, tracking, and pointing) tracker in action in both day and nighttime conditions. The imagery was captured with DRS Technologies’ infrared cameras. The ATP tracker used in this footage is the result of a Senior Capstone Project in Texas A&M’s electrical engineering program.
PHOTONICS ONLINE SPECIAL FEATURE
Xenics’ Serval-640-GigE is an LWIR camera designed for use in in-line process and quality control. It has a spectral band of 8µm to 14µm and 640x480 resolution. It’s been specifically designed for industrial imaging applications that call for rugged and reliable cameras without the need for third-party enclosures.

This Mid-IR laser source’s compact size, robustness, spectral flexibility, and low power consumption makes it ideal for applications involving molecular spectroscopy. This application note offers information on how it can be used for gas sensing.
Leveraging Semi-Solid Metal Casting For Manufacturing Complex Parts
Brisbane, California startup Fighting Walrus recently developed its Fighting Walrus Radio – a 900 MHz telemetry radio used in conjunction with iPhones or iPads in order to effectively control the flight of commercially available drones. This case study explains how Proto Labs helped them determine that a magnesium thixomolding process was the most ideal solution in developing the radio’s antenna housing and clamps. To see if thixomolding might be the ideal solution for your next design, (drone controller or otherwise), download the case study.
Overcoming Scattering Media Challenges In Multi-Photon Microscopy
A major problem standard MPM faces is correcting for scattering media. To solve this issue, Dr. Meng Cui at the Howard Hughes Medical Institute has recently pioneered Super Penetration Multi-Photon Microscopy (S-MPM) at the Cui Lab. He has successfully reported on focusing light through static and dynamic strongly scattering media using Boston Micromachines’ segmented 492-DM. By using the iterative multi-photon adaptive compensation technique (IMPACT), he since reported new results on in vivo fluorescence microscopy, providing a unique solution to noninvasive brain imaging.
Lens-Free Microscope Could Lead To Cheaper, Portable Imaging Tech
Research from the University of California at Los Angeles (UCLA) has led to a new, lens-free microscope that can detect cellular abnormalities like cancer. The portable system has a similar accuracy to the larger, more expensive equipment often found in pathology labs, so it may enable diagnostics in more remote areas.
Zapping Vocal-Cord Cancer With Lasers Proven Effective In Long-Term Study
A pioneering laser treatment for early vocal-cord cancer has shown promise as a long-term cure for the disease. In addition to being as effective as traditional approaches at curing tumors, the treatment developed at Massachusetts General Hospital is also able to spare the patient’s vocal cords and ability to speak.
