‘Cloaking’ Device Uses Ordinary Lenses To Hide Objects Across Range Of Angles

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.

    ‘Bendy’ LEDs

    "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
    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.

    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 Advantages Of Piezo-Based Scanning Systems For High-Performance Microscopes

    Very often, classical microscopic methods are no longer sufficient in terms of optical resolution or information content.

  • 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.
