81. Chemical Treatment Improves Quantum Dot Lasers 10/16/2017

    One of the secrets to making tiny laser devices such as opthalmic surgery scalpels work even more efficiently is the use of tiny semiconductor particles, called quantum dots.

82. Penn State's Biodegradable Optical Fiber Delivers Light Safely Into Human Body 10/12/2017

    Engineers at Pennsylvania State University (Penn State) have fabricated a new biodegradable optical fiber made of citrate-based polymers that can be implanted safely in the body to image deep tissue or deliver drugs.

     

83. Scientists Create Nanophotonic Device For Enhanced Single Cell-Based Sensing 8/31/2017

    Scientists at the Hebrew University of Jerusalem have successfully demonstrated a fully-integrated nanoscale photonic device that can analyze a single fluorescent bacterial cell. Such a unique system could result in the creation of on-chip sensors with the capability of analyzing cells and chemicals in real-time.

84. Water-Repellent Nanosheet Wrapper Enhances Biological Microscopy 8/24/2017

    Japanese scientists have developed a unique water-repellent nanomaterial that can be wrapped around biological tissue to visualize high-quality images for a longer period of time.

85. Vision Systems 101: Start With The Video Interface 8/7/2017

    Choosing the right video interface may mean the difference between success and failure for vision system designers. Although the video interface is a small part of the overall vision system, it has a large impact on the cost and usability of the final product.

86. New Imaging Technique Fast Enough To Watch Molecular Dynamics Involved In Neurodegenerative Diseases 7/13/2017

    Researchers have developed a fast and practical molecular-scale imaging technique that could let scientists view never-before-seen dynamics of biological processes involved in neurodegenerative diseases such as Alzheimer’s disease and multiple sclerosis.

87. UCSD Engineers Develop 'Near-Zero-Power' Temperature Sensor 6/30/2017

    Electrical engineers at the University of California San Diego have developed a temperature sensor that runs on only 113 picowatts of power — 628 times lower power than the state of the art and about 10 billion times smaller than a watt.

88. X-Ray Experiments Reveal Two Different Types Of Water 6/26/2017

    Liquid water exists in two different forms – at least at very low temperatures. This is the conclusion drawn from X-ray experiments carried out at DESY and at the Argonne National Laboratory in the US. An international team of researchers headed by the University of Stockholm now reports its findings in the Proceedings of the National Academy of Sciences (PNAS).

89. X-ray Pulses Create 'Molecular Black Hole' 5/31/2017

    Scientists have used an ultra-bright pulse of X-ray light to turn an atom in a molecule briefly into a sort of electromagnetic black hole.

90. Fluctuations In Optical “Noise” Used To Track Hidden Objects 4/24/2017

    A new remote sensing method devised by researchers at the University of Central Florida (UCF) using fluctuations in optical "noise" could one day complement existing technologies to track hidden objects, such as Light Detection and Ranging (LIDAR).
