81. Driggers, Friedman, Devitt, Furxhi, Singh are recipients of the 2024 Joseph W. Goodman Book Writing Award for Introduction to Infrared and Electro-Optical Systems, Third Edition 3/13/2024

    SPIE and Optica have announced Ronald G. Driggers, Melvin H. Friedman, John W. Devitt, Orges Furxhi, and Anjali Singh as the 2024 recipients of the Joseph W. Goodman Book Writing Award for their Introduction to Infrared and Electro-Optical Systems, Third Edition.

82. Photovoltaic Nanotubes 6/20/2019

    Physicists discovered a novel kind of nanotube that generates current in the presence of light. Devices such as optical sensors and infrared imaging chips are likely applications, which could be useful in fields such as automated transport and astronomy. In future, if the effect can be magnified and the technology scaled up, it could lead to high-efficiency solar power devices.

83. Chemists Develop New "Light Switch" Chloride Binder 9/1/2010
    Chemists at Indiana University Bloomington have designed a molecule that binds chloride ions -- but can be conveniently compelled to release the ions in the presence of ultraviolet light.
84. Sunflowers Inspire More Efficient Solar Power System 8/15/2012

    A field of young sunflowers will slowly rotate from east to west during the course of a sunny day, each leaf seeking out as much sunlight as possible as the sun moves across the sky through an adaptation called heliotropism.

85. IPG Photonics Launches Cobot Laser Welding And Cleaning System 5/8/2024

    IPG Photonics Corporation (NASDAQ: IPGP), the world leader in fiber laser solutions, today announced the launch of an automated cobot laser welding and cleaning system for fabrication and manufacturing industries.

86. High-Speed Infrared Imaging For Analysis Of A Diesel Engine Supplied With Premixed Methane-Air Charge 6/10/2016

    Engineers are continuously looking to improve the efficiency of internal combustion engines (ICEs). This white paper walks through this experiment and investigates the different phases of the combustion cycle using four different spectral filters in order to see the difference in the exhaust fumes.

87. Major Advance In Solar Cells Made From Cheap, Easy-To-Use Perovskite 11/7/2016

    Solar cells made from an inexpensive and increasingly popular material called perovskite can more efficiently turn sunlight into electricity using a new technique to sandwich two types of perovskite into a single photovoltaic cell.

88. Phase-Transition Cubic Gallium Nitride Doubles Ultraviolet Emission Efficiency 2/19/2018

    Novel photonics materials are becoming pivotal for energy conversion, communications, and sensing, largely because there is a global desire to enhance energy efficiency, and reduce electricity consumption.

89. Research Pinpoints New Technique For Producing Cheaper Solar Energy 1/23/2015

    A team of experts from the University of Exeter has examined new techniques for generating photovoltaic (PV) energy – or ways in which to convert light into power – more cost efficiently.
