Ultraviolet-emitting chips installed in light fittings could play "a significant role in fighting the pandemic"
A new generation of compact chips could safely neutralise airborne coronavirus in buildings, vehicles and even outdoor spaces using far-UVC radiation, according to Seth Coe-Sullivan of technology company NS Nanotech. Read more A new generati.....»»
Information transition mechanisms of spatiotemporal metasurfaces
Spatiotemporal metasurfaces are analyzed from an information perspective, in which two information transition mechanisms on group extension and independent control of multiple harmonics are revealed and characterized. The information transition effic.....»»
Arbitrary polarization conversion dichroism metasurfaces for full Poincaré sphere polarizers
Polarization control is essential for tailoring light-matter interactions and is the foundation for many applications such as polarization imaging, nonlinear optics, data storage, and information multiplexing. A linear polarizer, which is a polarizat.....»»
"Urban Sun is not intended to create a guaranteed safe space" says Studio Roosegaarde
Studio Roosegaarde's Urban Sun proposal to use ultraviolet lights to make outdoor spaces safer from Covid-19 can only be used at night and people still need to wear masks and observe social distancing, the designer has explained. Read more S.....»»
High end of climate sensitivity in new climate models seen as less plausible
A recent analysis of the latest generation of climate models—known as a CMIP6—provides a cautionary tale on interpreting climate simulations as scientists develop more sensitive and sophisticated projections of how the Earth will respond to incre.....»»
Daan Roosegaarde develops Urban Sun to make public spaces "virus-free in minutes"
Studio Roosegaarde has built a light that uses ultraviolet radiation to sanitise outdoor spaces, claiming this could reduce the risk of people contracting Covid-19. Read more Studio Roosegaarde has built a light that uses ultraviolet radiati.....»»
Teaching a machine how to identify imperfections in 2-D materials
Just as James Cameron's Terminator-800 was able to discriminate between "clothes, boots, and a motorcycle," machine-learning could identify different areas of interest on 2-D materials......»»
UV light shows promise in mitigation of costly swine virus
Let there be (ultraviolet) light......»»
SK Hynix strikes 5-year deal with ASML for EUV equipment supply
SK Hynix has signed a 5-year contract worth KRW4.75 trillion (US4.3 billion) with ASML to procure extreme ultraviolet (EUV) lithography systems, local media reports in South Korea quoted the memory chipmaker as saying......»»
Copper-doped zinc sulfide changes color reversibly when illuminated and could be used in smart adaptive windows
Photochromic materials can reversibly change their color and optical properties when irradiated with ultraviolet or visible light. However, they are made from organic compounds that are expensive to synthesize. Fortunately, for the first time, scient.....»»
Scientists image a bright meteoroid explosion in Jupiter"s atmosphere
From aboard the Juno spacecraft, a Southwest Research Institute-led instrument observing auroras serendipitously spotted a bright flash above Jupiter's clouds last spring. The Ultraviolet Spectrograph (UVS) team studied the data and determined that t.....»»
Ultraviolet "television" for animals helps us better understand them
University of Queensland scientists have developed an ultraviolet 'television' display designed to help researchers better understand how animals see the world......»»
Toward a disease-sniffing device that rivals a dog"s nose
A new system can detect the chemical and microbial content of an air sample with even greater sensitivity than a dog's nose. Researchers coupled this to a machine-learning process that can identify the distinctive characteristics of the disease-beari.....»»
Researchers flip the switch to make microsensors super sensitive to biomolecules
A team led by researchers at the New York University Tandon School of Engineering have found a new way of enhancing the performance of electrochemical micro-sensors. This discovery could lead to the detection of biomolecules, such as dopamine, at low.....»»
Breakthrough material can protect satellites from ultraviolet radiation and atomic oxygen in low-Earth orbit
Atomic oxygen is created when O2 molecules break apart, a process made easier in space because of the abundance of ultraviolet radiation. According to NASA, 96 percent of low-Earth orbit's atmosphere is atomic oxygen, a reality that caused problems i.....»»
How zero-trust approach can help SMBs focus on growth without losing sight of security
Ransomware or malware doesn’t necessarily discriminate among small or big businesses. Unscrupulous elements may prey upon anyone who has kept doors to their internal networks ajar. Small businesses often compromise their network security due to bud.....»»
A New Lens Technology Is Primed To Jump-Start Phone Cameras
An anonymous reader quotes a report from Wired: A new company called Metalenz, which emerges from stealth mode today, is looking to disrupt smartphone cameras with a single, flat lens system that utilizes a technology called optical metasurfaces. A c.....»»
