Inspired perhaps by Harry Potter’s invisibility cloak, scientists have recently developed several ways—some simple and some involving new technologies—to hide objects from view.
On The Road To Artificial Photosynthesis
The excessive atmospheric carbon dioxide that is driving global climate change could be harnessed into a renewable energy technology that would be a win for both the environment and the economy.
"Bendy" light-emitting diode (LED) displays and solar cells crafted with inorganic compound semiconductor micro-rods are moving one step closer to reality, thanks to graphene and the work of a team of researchers in Korea.
Solar Explosions Inside A Computer
The shorter the interval between two explosions in the solar atmosphere, the more likely it is that the second flare will be stronger than the first one. ETH Professor Hans Jürgen Herrmann and his team have been able to demonstrate this, using model calculations.
Iridian Spectral Technologies' multi-zone filters offer optical designers spatially varying spectral performance on a single substrate in the UV (300nm) to LWIR (15µm) wavelength range. Filter types available include bandpass, notch, long-pass, and short-pass with additional coatings offered for AR, high-reflectivity, and black-absorbing.

Amazon’s New Smartphone Boasts High-End RF And Imaging Components
On July 25, Amazon released its first smartphone, and it didn’t take long for the internal components of the device to get leaked.
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.

Impedance-Based Pathogen Detection
Electrochemical impedance spectroscopy (EIS) is an important detection technique for biosensors. Since its conceptual introduction in the late 19th century, impedance spectroscopy has undergone a tremendous evolution into a rich and vibrant multidisciplinary science.
Identification Of Forensic Fabrics Using A Portable Raman Spectrometer
In recent years, Raman spectroscopy has been studied extensively for forensic fiber analysis because of the high selectivity of Raman signatures, non-destructive nature of the test, and the ability to conduct analysis without any sample preparation. The Raman test can be performed directly on fabrics or fibers mounted on glass slides with very little interference from the mounting resin or the glass. This study describes how six types of undyed fabric samples were tested using a 1064 nm laser and a fiber optic probe holder, demonstrating Raman spectroscopy’s practicality and unique discrimination power.
Infrared Cameras for Safety
Infrared cameras are incredibly useful when used in safety related applications. They can improve a driver’s sight in low light or foggy conditions, detect smoke or fire at its onset from a long distance, or image through dense smoke in order to detect trapped victims in danger, and can even be used to detect fevers in people carrying an infectious disease.
