Washington State University researchers have developed an environmentally-friendly, plant-based material that for the first time works better than Styrofoam for insulation.

The is mostly made from nanocrystals of cellulose, the most abundant plant material on earth. The researchers also developed an environmentally friendly and simple manufacturing process to make the foam, using water as a solvent instead of other harmful solvents.

The work, led by Amir Ameli, assistant professor in the School of Mechanical and Materials Engineering, and Xiao Zhang, associate professor in the Gene and Linda School of Chemical Engineering and Bioengineering, is published in the journal Carbohydrate Polymers.

Plastics are useful and ubiquitous – but that’s not always a good combination. The vast majority of plastic waste can’t be recycled, meaning it ends up in landfills at best or the ocean at worst. To help curb the problem, researchers at Berkeley Lab have now designed a new type of plastic that can apparently be reduced right back to its molecular parts, before being remade over and over.

The US Defense Advanced Research Projects Agency (DARPA) is eyeing flight tests later this year for two hypersonic weapons, and it is teaming up with the US Army on developing such a ground-launched capability. However, at the same time, army leaders are drafting plans to consolidate duelling lines of effort within their hypersonic weapons’ portfolio.

During a 1 May Defense Writers’ Group breakfast with reporters, DARPA Director Dr Steven Walker fielded questions about ongoing projects inside the Pentagon’s research arm including the development of two hypersonic weapons with the US Air Force (USAF) — the Tactical Boost Glide (TBG) and the Hypersonic Air-breathing Weapon Concept (HAWC).

“[They are] two very different concepts but when you’re talking hypersonic [weapons], it is good to have what I consider intended redundancy because it’s a hard technology, making materials and propulsion systems that last in 3,000° Fahrenheit temperatures is not easy,” Walker said.

We’re committed to accelerating scientific progress for the benefit of society. One way we do this is through releasing open source materials, to contribute to the AI community’s culture of collaboration and shared progress.

Along with publishing papers to accompany research conducted at DeepMind, we release open source environments, data sets, and code to enable the broader research community to engage with our work and build upon it. For example, you can build on our implementations of the Deep Q-Network or Differential Neural Computer, or experiment in the same environments we use for our research, such as DeepMind Lab or StarCraft II.

Our open source contributions can be viewed on our site and on GitHub.
