Stay tuned!

Scientists at Newcastle University in England have made a breakthrough insulating mortar using aerogel and recycled PET plastic (the most difficult to recycle plastic and often ending up in landfills) that reduces heat loss 55% over normal mortar while still meeting all British construction standards.

At long last—seven years in the making, thousands of hours of writing and editing, and wrangling the works of hundreds of contributors—it is my distinct pleasure to announce the publication of The Springer Handbook of Aerogels! The Springer Handbook series is the flagship research reference line of books published by SpringerNature, the world’s leading academic publisher. This particular work is available in hard copy in their largest format wielding about the maximum allowable page limit before it would have had to be two volumes, amounting to what is undoubtedly the most comprehensive and definitive resource about aerogels ever compiled. This ironically dense and heavy book about the world’s lightest solids is also available for download in pdf format and is a must-have reference for any emerging or experienced researcher in the field.

I served as co-editor for the book and contributed many chapters, including a section titled “Unit Operations” that includes five chapters walking through the basics of sol-gel, solvent exchange, shape control, drying, and postprocessing as these steps apply to aerogels. Also featured are a deep dive into the aerogel industry featuring profiles for over 50 aerogel producers and a step-by-step recipes and designs chapter with hand-picked procedures for dozens of aerogel compositions, how to build a calibrated hot plate for accurately measuring thermal conductivity of aerogels, and an updated guide on how to build and operate a supercritical dryer based on the Aerogel.org tutorial.

The book is available for purchase now and is available for download without purchase through most university library systems.

Aerogel Technologies was recently featured in an awesome viral video about aerogels on YouTuber Derek Muller’s Veritasium channel.  Unfortunately, the millions-of-views-per-day popularity of the video crippled the Aerogel Tech and BuyAerogel.com servers for everybody looking for aerogel samples!  In the mean time, anyone interested in buying an aerogel sample can email aerogeltechnologies@gmail.com and someone will reach out to you when the servers are back up.  To make up for the epic fail, anybody who emails requesting a sample before June 2, 2019 will get a coupon for 10% off their order*.

Researchers at Boston-based Aerogel Technologies, LLC have developed a new technique that, for the first time, enables production of aerogel parts with plastic-like durability in theoretically unlimited dimensions.  This new approach opens the possibility of using aerogels for a wide range of new applications at price points that the company projects will soon be cost-competitive with performance plastics like polycarbonate.

Aerogels are traditionally made using a technique called supercritical drying—a high-pressure process also used in decaffeinating coffee and green dry cleaning performed in expensive stainless steel reactors.  But just as a pizza is limited to the size of an oven, to date aerogels have been limited to size of the supercritical dryers used to make them, meaning parts no bigger than about 60 cm x 60 cm.  This has greatly limited potential applications and has made scaling production extremely costly.  Using their new technique, which the company calls the Stelmakh process, Aerogel Technologies has produced a whopping 90 cm x 90 cm aerogel panel, making it the world’s largest aerogel to date.  The aerogel, made of a proprietary polymer, weighed in at an impressive 7x lighter than typical plastics.  Unlike traditional aerogel production, the new manufacturing technique developed by Aerogel Technologies is performed at ambient conditions eliminating the need for a pressure vessel and enabling production of aerogel parts of theoretically unlimited dimensions.  Aerogel Technologies is already producing 30 cm panels using this technology available for purchase at pre-scale prices through their website BuyAerogel.com.  The company is currently scaling the process to produce panels up to 2 m x 3 m in thicknesses up to 5 cm.

World’s largest aerogel to date made using new drying technology invented by Aerogel Technologies, LLC.

The Fourth International Seminar on Aerogels will be held this September 24-26 in Hamburg, Germany at the Hamburg University of Technology.  This is the fourth installment of this conference series and last time had over 175 attendees.  This year promises to be even bigger and better and will showcase the latest in the rapidly growing field of aerogels.

People have been hearing about mechanically strong aerogels such as x-aerogels and strong organic aerogels like polyimide aerogels along with all of their promise for use as ultralightweight structures, dust-free superinsulation, and science-fiction-y applications for some time now.   Small samples of strong aerogels have been commercially available for the past couple years, but nothing much bigger than the size of a playing card, or the back panel of a Google Nexus 7 tablet, meaning there has not been a whole lot of movement using these materials for improving building efficiency, making ultralight cars, or building what we all really care about deep down inside, flying cars and hoverboards–applications where ultralight materials could have a significant on reducing carbon dioxide emissions and saving fuel costs.

Well good news.  Aerogel Technologies today announced that they are now manufacturing large (one-foot, 30-cm) panels on its new pilot line, and that these panels are soon to be followed by even larger panels.  The company plans to market these materials as lightweight replacements for plastics for use anywhere weight and cost are coupled, for example, in cars, planes, and refrigerated trucks.

Strong aerogel panels made of Airloy X103, a high-strength organic aerogel that is stable to about 80°C, are being made available on BuyAerogel.com.  Other formulations including new high-temperature Airloy X114 are soon to follow.

Aerogel Technologies has released a new high-temperature, high-strength machinable aerogel material called Airloy X114 which is stable up to 300°C and has the strength and durability of a plastic but is three times lighter.  They’re apparently good at sound damping too.  Aerogel Technologies says applications include insulating engine compartments, ovens,, and rocket parts.  Samples of Airloy X114 are available for purchase on BuyAerogel.com.

Airloy X114 high-temperature strong aerogel from Aerogel Technologies goes up to 300°C, is strong like a plastic, and three times lighter than plastic.

The team at Lukla Apparel has just launched a Kickstarter campaign to raise money for their new aerogel jackets.  Lighter and less bulky than traditional aerogel jackets, their Endeavor jacket was designed for back-country skiing, which has high technical demands and in which people need to keep warm and comfortable for long periods of time.  I had the chance to talk with the Lukla team recently and they’ve done some great work looking at how to integrate aerogel blankets into an aerogel jacket while still making it comfortable, not dusty, and washable.  Check out their Kickstarter campaign and help them raise $100,000.
