FSU researchers develop thin heat shield for superfast aircraft

November 12, 2019 sarah Jonas 0 Comments Materials Science

The world of aerospace increasingly relies on carbon fiber reinforced polymer composites to build the structures of satellites, rockets and jet aircraft. But the life of those materials is limited by how they handle heat. A team of FAMU-FSU College of Engineering researchers from Florida State University’s High-Performance Materials Institute is developing a design for a heat shield that better protects those extremely fast machines.

Machine learning analyses help unlock secrets of stable ‘supercrystal’

November 7, 2019 sarah Jonas 0 Comments Artificial Intelligence, Computing, laser pulses, Machine Learning, Materials Science, OPTICS

By blasting a frustrated mixture of materials with quick pulses of laser light, researchers transformed a superlattice into a supercrystal, a rare, repeating, three-dimensional structural much larger than an ordinary crystal. Using machine learning techniques, they studied the underlying structure of this sample at the nanoscale level before and after applying the laser pulse treatment.

Stitching It All Together

November 6, 2019 sarah Jonas 0 Comments Materials Science, Self Healing Materials

The future of materials science covers a smorgasbord of applications: batteries that self-repair, wind turbines robust enough to withstand the extreme forces put on them, or long-lasting devices that only require replacing small parts every so often. Before getting to these applications, these basic science questions need to be answered. These questions are one reason the Department of Energy (DOE) supports research in this area at universities and national laboratories around the country.

Engineering Living Scaffolds for Building Materials

October 29, 2019 sarah Jonas 0 Comments Chemistry & Materials, Materials, Materials Science

Bone and mollusk shells are composite systems that combine living cells and inorganic components. This allows them to regenerate and change structure while also being very strong and durable. Borrowing from this amazing complexity, researchers have been exploring a new class of materials called engineered living materials (ELMs).

Investigating Materials that Can Go the Distance in Fusion Reactors

October 15, 2019 sarah Jonas 0 Comments Fusion, Fusion Energy Sciences, fusion reactor, Materials Science

Future fusion reactors will require materials that can withstand extreme operating conditions, including being bombarded by high-energy neutrons at high temperatures. Scientists recently irradiated titanium diboride (TiB2) in the High Flux Isotope Reactor (HFIR) to better understand the effects of fusion neutrons on performance.

Even Hard Materials Have Soft Spots

October 10, 2019 sarah Jonas 0 Comments Basic Energy Sciences, Materials Science

The Achilles Heel of “metallic glasses” is that while they are strong materials—even stronger than conventional steels—they are also very brittle. The initial failures tend to be localized and catastrophic. This is due to their random amorphous (versus ordered crystalline) atomic structure. Computer simulations revealed that the structure is not completely random, however, and that there are some regions in the structure that are relatively weak. Defects nucleate more easily in these regions, which can lead to failure. This understanding of the mechanical properties has led to a strategy for making the material stronger and less brittle.
