So, knowing a bit about how #BoricAcid can absorb #Radiation, I think we're onto something here. Not that we should create more #NuclearWaste. But we do need to store the stuff we've already produced safely!

UrFU Scientists Have Developed #Ceramic Material that Protects Against Radiation

Friday, November 7, 2025

"Scientists at Ural Federal University, in collaboration with colleagues from Iraq and Saudi Arabia, have developed a durable, inexpensive, and environmentally friendly ceramic material that protects against radiation. The new material is made from natural clay and recycled glass waste.

"Researchers believe this ceramic can be used in radiation-hazardous facilities, X-ray rooms, and laboratories to protect medical, scientific, and industrial personnel. The results of the study were published in the Journal of Science: Advanced Materials and Devices.

" 'We mixed clay imported from Iraq with glass production waste and a small amount of Boric acid. This allowed us to create durable and inexpensive ceramics that effectively protect against gamma radiation. The addition of glass increases the strength of the tile. This method allows for the disposal of glass waste in building materials, including it, which is particularly important for the construction of radiation-hazardous facilities and X-ray rooms where the use of lead is undesirable,' said Karem Makhmud, Head Specialist of the Department of Nuclear Power Plants and Renewable Energy Sources."

A detailed design for a space station at sun–Earth L2

New ideas in space exploration come from all corners, and, by and large, the community welcomes anybody interested in the field. Having just read "A City on Mars," it seems that even people who disagree with the idea that the age of space settlement is imminent will be accepted into the fold by enthusiasts. Now, a new entrant has joined—Daniel Akinwumi is a Nigerian graduate student at the University of Strathclyde who recently posted his master's thesis to ResearchGate detailing the design of the "intergalactic hub," or I-HUB.
