To aid orthodontists in use of new orthoscrew
The newly Food and Drug Administration-approved orthoscrew--so tiny it is dwarfed by a fingertip--is difficult to place between the narrow spaces of teeth roots and bone.
Young Jin Jeon, a visiting assistant professor at the Case Western Reserve University School of Dental Medicine and an orthodontist from Pusan National University in Korea, developed a new grid device during his yearlong residency at Case that will help orthodontists accurately place and guide the newly approved mini-orthoscrews without damaging the teeth.
Called the JJ Aligner, which looks like a tiny half-inch plastic square of graph paper, is attached by the orthodontist to patients jaw and then x-rayed to show where teeth roots and bone are in relations to the grid. After the patients gum tissue has been numbed (much like that for a dental filling), the orthodontist will implant the screw using the combination of the x-ray and the grid as a guide. Jeon has a patent pending in Korea on the device. When he returns to Korea at the end of June, he plans to form a company to manufacture the grids for the eventual use in Korea and the United States.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).
Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...
