Ultrafast lasers and Archimedes - Scientists & Engineers on Sofas (and other furnishings)

submitted by: nsf
When it comes to ultrafast lasers, Margaret Murnane’s name is one of the best known for her work in this field of science. Since 1999, she has been a professor at the University of Colorado’s NSF-funded JILA Physics Frontier Center, where she and her husband Henry Kapteyn pioneer research in ultrafast x-ray science. Additionally, the two also own a small laser company. Margaret is credited with building one of the fastest lasers ever, operating in matters of merely femtoseconds. After a...

Local 3D printing hubs bring manufacturing back to U.S.

submitted by: nsf
Imaginestics is a start-up out of West Lafayette, Indiana, founded by Nainesh Rathod. At the Smart America Expo, Rathod was part of a team that demonstrated the potential impact of "Smart Shape Technology" on 3D printing and local manufacturing hubs. The system lets you can take a picture of a part of a larger device with a mobile phone, and then identify a local retailer where this part can be found or instantly print it at a local neighborhood 3D printing service provider. The...

Materials Genome Initiative: Three Years of Progress

submitted by: nsf
Advanced materials are essential to human well-being and are the cornerstone for emerging industries. Yet today, it can take ten to twenty years or more from initial research on a new material to first use. That's why in June 2011 President Obama launched the Materials Genome Initiative (MGI) "to help businesses discover, develop, and deploy new materials twice as fast" and at a fraction of the cost. The MGI brings together academic institutions, small businesses, large industrial...

Deformation and fracture incidence of Reciproc instruments: a clinical evaluation.

submitted by: gplotino
Aim To investigate the incidence of fracture and deformation observed on Reciproc instruments after clinical use. Methodology A total of 1696 Reciproc NiTi instruments that were discarded after normal clinical usage over 30 months were collected, 1580 instruments were R25 (93%), 76 were R40 (5%) and 40 were R50 (2%). The treatments included 3780 root canal preparation, 3023 primary treatments and 757 retreatments. Root canal preparation was standardized and followed the manufacturer's...
