Designing cleaner, greener concrete that absorbs carbon dioxide
Masoud Akbarzadeh holding up one of the fabricated materials.

The Polyhedral Structures Laboratory is housed at the Pennovation Center and brings together designers, engineers, and computer scientists to reimagine the built world. Using graphic statics, a method where forces are mapped as lines, they design forms that balance compression and tension. These result in structures that use far fewer materials while remaining strong and efficient.

Designing cleaner, greener concrete that absorbs carbon dioxide

Penn engineers, materials scientists, and designers have developed a 3D-printed concrete solution based on diatomaceous earth that has enhanced carbon capture, is stronger, and uses fewer materials like cement.

New teacher-staffing model rethinks ‘one-teacher, one-classroom’

A new study by Penn GSE’s Richard Ingersoll evaluates a team-based model of organizing teaching staff in elementary and secondary schools that integrates teams of teaching staff in contrast to this traditional one-teacher, one-classroom approach.

Can data from the Large Hadron Collider snap string theory?
Close-up of ATLAS detector at CERN.

ATLAS’s wheel-like end-cap reveals the maze of sensors primed to catch proton smash-ups at the LHC. Researchers comb through billions of events in search of fleeting “ghost” tracks that might expose cracks in string theory.

Can data from the Large Hadron Collider snap string theory?

Theoretical physicist Jonathan Heckman of the School of Arts & Sciences has put a spin on ideas related to testing string theory: Rather than looking to verify it, he and his collaborators sought a novel way to falsify it. Heckman and Ph.D. candidate Rebecca Hicks explain string theory, researchers’ quest to unify physics, and what their new paper puts forward.
