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.

24th International Commission on Glass Congress in Shanghai

The 24th International Congress on Glass (ICG) took place April 7–11, 2016, at the Shanghai International Convention Centre in China. ICG is a non-profit international glass society consisting of 37 national organizations in glass science and technology, which together promote cooperation among glass experts.
The Chinese Ceramic Society, working with the International Commission on Glass, hosted the 24th meeting. This triennial event has a long pedigree—it began in Venice, Italy, in 1933 and has continued ever since, apart from a break during World War II. Shanghai built on the meeting’s most valued traditions whilst successfully introducing new ideas to maintain its freshness and appeal.
The Congress Chairman was Professor Shou Peng of China Triumph International Engineering Co., the immediate past president of ICG, who called on the glass community to take this opportunity to join hands and make common efforts for healthy and sustainable development of the glass industry and to realize our beautiful “glass dreams” for the benefit of mankind. Professor Jianrong Qiu chaired the scientific committee, while Mr. Zhanping Jin chaired the organizing committee.
The setting for the event, the SICC building, combines a hotel with dedicated conference facilities. Sited in the Pudong New Area of Shanghai on the east bank of the Huangpu River at one end of the Bund district, it faces the old trading area of Shanghai on the western bank where many of the buildings retain their early 20th century European architectural style. Its immediate surroundings, however, are a monument to glass and include some of the tallest towers in the world—most encased in their transparent protective cocoons.

Borosilicate glass continues to fuel science and invention after 125 years

   1891 was a year of invention and discovery. The Wrigley Company launched what would become a gum empire, Thomas Edison patented the motion picture camera, James Naismith thought up basketball, and the escalator was invented. But perhaps most important of all, a new form of glass was manufactured in Germany — borosilicate glass.
   Borosilicate glass’s long and productive life is showing no signs of slowing, as it continues to enable innovation across a wide spectrum of industries including space exploration, semiconductors, and even architecture. Its power lies in its simple chemistry – composed of just four basic materials – which give it special properties aiding everything from microscopes and housing for 360-degree cameras to telescopes.

Bižuterní a sklářský průmysl: schází pasíři a sklofoukači

  „Máme za sebou období deprese a naše odvětví je stabilizované. Jenže se citelně začíná projevovat nedostatek pracovní síly, odborníků. Zejména chybí pasíři, foukači skla, ale i lidé, kteří bižuterii montují,“ říká předseda Svazu výrobců skla a bižuterie Pavel Kopáček.
  „Děti tyto obory studovat nechtějí, školy je těžko obsazují. Podle našich informací na pasíře momentálně studuje v Česku jen 15 žáků. Loni vyšla ze školy jen jedna studentka. Tomuto průmyslu chybí asi 30 lidí ročně. A vezměte si, že na Jablonecku se bižuterii věnuje 4 032 lidí a v dobách největší slávy jablonecké bižuterie tu bylo kolem 250 jen pasířů,“ vypočítává Kopáček.
   Jednou z cest, jak tento stav změnit, je nový projekt svazu, na kterém spolupracuje s úřadem práce.

Sklárny Rückl Crystal koupil Martin Wichterle

   Známé sklárny Rückl Crystal se stoletou historií, které vyráběly například sošky pro Českého lva a nyní jsou téměř rok v úpadku, získá přední český továrník Martin Wichterle. Ten vlastní zejména strojírenskou skupinu Wikov, dva roky se ale pohybuje i ve sklářství.
   Dlouho se hovořilo o tom, že sklárny z Nižboru na Berounsku chce získat Lubor Cerva, který vlastní sklárny Crystalite Bohemia. Do této skupiny spadají provozy ve Světlé nad Sázavou nebo nejdéle fungující sklárny v zemi v Květné na Slovácku. Cerva ale svou nabídku na sklárny Rückl nakonec stáhl.
Podle zjištění Hospodářských novin tak středočeské sklárny proslavené broušeným a zdobeným křišťálem získá Wichterle. Ten se k připravovanému nákupu odmítl vyjádřit s tím, že komentuje až definitivně uzavřené transakce.

Umělecko-průmyslová škola sklářská Železný Brod znovu otvírá obor technologie skla

Ve čtvrtek 24.února uspořádala  Střední umělecko-průmyslová škola sklářská v Železném Brodě  svůj Den otevřených dveří. Stalo se tak něco, v co dlouho nikdo nevěřil-sklářské firmy volaly po nových technolozích skla. Ředitel školy Libor Doležal k tomu dodává: „ještě na přelomu tisíciletí byl trh nasycený, odbytová krize se zdála být nekonečnou a čínská konkurence hrozila naše sklářství postupně likvidovat. Teď se situace výrazně zlepšuje, firmy vidí, že jim lidé stárnou a odchází do důchodu. Proto volají po nových technolozích, aby se ještě pod těmi starými naučili všechny praktické úkony".
