New window glass changes from clear to dark in 30 seconds

  Wouldn’t it be great if the windows in your home had the built-in capability of darkening on bright sunny days, keeping your air conditioning from constantly running?  A Stanford University research team has created a new type of smart window that blocks light by using electrodeposition to shoot an electrical current through conductive glass containing metal ions. Electrode position, or electroplating, is a process that uses an electric current to coat a material with a thin layer of metal. The window changes from transparent to dark in less than a minute.
 Current smart windows change color when charged with electricity. Michael McGehee, professor of materials science and engineering at Stanford and lead researcher, says tungsten oxide, a typical metal used in commercial smart windows, tends to give the windows a bluish tint and is more expensive. It also takes at least 20 minutes for commercial windows to dim and, over time, they become less opaque.

Glass photobioreactor for energy of the future

  At EXPO 2017, LGem presented microalgae as an energy-efficient product of the future. Dutch algae cultivation platform specialist Sander Hazewinkel of LGem answered our questions concerning their presence at this event organized under the  motto “Future Energy.”

Sander Hazewinkel,
Chief Commercial Officer
of the photobioreactor manufacturer  LGem.

  
What do microalgae have to do with this motto? Will we have algae-powered cars in the future?
Microalgae save fossil fuels, but I don’t mean by using it as biofuel as much as that it allows for more energy-efficient production. The best example is omega-3 fatty acids. They come from fish oil. Four kilograms of fish – herring, mackerel or salmon for instance – are needed for every liter of oil. Starting with the fuel for the fish trawler and going up through further processing, all the production steps require enormous amounts of energy. If the same amount of omega-3 fatty acids can be obtained from microalgae biomass, the energy demand is 90 percent lower.

to 3-D print high-quality microstructured glass

Work on technologies
 
   Almost 2 years ago, Micron3DP demonstrated one of the earliest forays into 3-D printing with glass. And just a few months later, MIT backed up glass’s place in the additive manufacturing realm and showed just how beautiful the possibilities were.  But although intriguing, those early demonstrations were only able to produce rather imprecise glass components with poor resolution—on the order of millimeters—because they printed in molten glass.
   While that’s good enough for glass vases, bowls, and other artistic expressions, it just doesn’t cut it for the wide range of high-tech applications of glass that require intricate and precise microstructures. To really open up the world of additive manufacturing for glass, we need techniques that can print with better resolution, precision, and detail, which is hard to achieve with molten glass.
  Now, two new papers, one published in Nature and one in Advanced Materials, describe 3-D printing techniques that use silica nanoparticle inks—rather than molten glass itself—to fabricate optically clear glass components with micrometer-scale resolution, a huge leap forward for the integration of glass materials into additive manufacturing.

Flexible glass lab-on-a-chip devices as medical sensors

    Medical diagnostics have come a long way,  this is no surprise in an age when robots can read your mind and driverless cars are becoming reality. Take for instance blood tests: they usually require you to part with several vials of your blood, can take weeks to provide results, and can come with a pretty hefty price tag.
 Now  there is some interesting novelty  in the branch:They’re called lab-on-a-chip—tiny devices that shrink the components of a full laboratory down to a tiny scale. And they’re incredibly valuable because lab-on-a-chip devices reduce the equipment, consumables, resources, sample quantity, and personnel required for laboratory-based diagnostic tests. It miniaturizes and compacts all the different processes that a researcher or a technician in the diagnostic lab uses.These types of rapid medical diagnostics might soon become reality by incorporating one of our favorite materials—glass.

There are about 300 million colourblind people around the globe. According to the National Eye Institute, 8% of men and 0.5% of women have the most common form of color blindness, which is red-green colorblindness. This mild disability, also known as color vision deficiency (CVD), is inherited—men are more likely to be colorblind than women because the gene for the trait is on the X chromosome.

Guardian Glass to Add Jumbo Coater

Dramatically Expands Architects’ Options

Guardian Glass is installing a jumbo coater in North America to serve its North America commercial glass customers. The investment was approved by the Guardian Industries Corp. Board of Directors.

 

    Architects are increasingly designing projects with larger glass sizes. Adding the ability to coat jumbo-sized glass means Guardian can supply bigger sheets of coated glass to its customers for fabrication into finished sizes for glass facades and windows. This supports the architectural trend to more expansive views and higher daylight penetration in buildings with the world-class energy savings of the Guardian SunGuard® portfolio of high performance, low-E coatings.
  For U.S. projects such as the Eli and Edythe Broad Art Museum at Michigan State University - one of the first Zaha Hadid-designed buildings in America - Guardian supplied jumbo-sized coated glass from one of its plants in Europe, which has had this capability for some time. “The new coater will allow us to deliver jumbo-sized glass to our North American customers with significantly reduced lead times,” explains Chris Dolan, Director of Marketing, Guardian Glass North America.

Glass avalanches help explain phenomenon behind energy-saving technique

 
Charles McLaren  and Himanshu Jain from Lehigh University have gained knowledge
into how applying a direct current field across glass reduces its melting temperature

  Earlier this year, we reported on how a team of scientists led by Lehigh University researcher Himanshu Jain was pioneering a technique called electric field-induced softening that used an electric field to lower the intense amount of heat needed to form glass.
 Although the team’s results offered exciting implications for reducing the high energy requirements of glass processing—and also offered interesting possibilities for micro- and nano-structuring of glass that is not possible with other techniques—the scientists didn’t understand why it was happening.

Scientists find the temperature at which glass becomes a liquid

    Inert gas permeation, a technique developed at PNNL, is used to investigate the formation of stable glasses. The stability of glass is not meant in terms of normal household usage, the stability of glass affects areas as diverse as nuclear waste storage, pharmaceuticals, and ice cream.
    Recently, chemical physicists at Pacific Northwest National Laboratory made a key discovery about how glass forms. They discovered that the temperature at which glass-forming materials are deposited on a substrate affects the stability. Their findings show the ability of a technique called inert gas permeation to tell at what temperature a solid "melts." Their work brings more understanding to the fundamental properties of glass.

That pretty layer on the picture  is called nacre, and it’s what makes seashells strong and durable. Nacre’s “work of fracture is 3,000 times greater than that of pure ceramic,” mostly because of its ingenious structure.  It’s composed of a form of calcium carbonate called aragonite that is arranged in repetitive nanoscale bricks, like a tiny mason was commissioned to build each mollusk’s seashell home, nanobrick by nanobrick (see image to the right). Those bricks provide structure and stability, and they are separated by layers of elastic biopolymer that give the nacre flexibility and durability.
