A great deal is made of how many great scientific discoveries are made by accident for everything from penicillin to Post-its®.   With no fewer than ten authors for the Nature letter “Production of phosphorene nanoribbons,” their discovery hardly seems “accidental.”  The letter, authored by Mitchell C. Watts, Loren Picco, Freddie S. Russell-Pavier, Patrick L. Cullen, Thomas S. Miller, Szymon P. Bartuś, Oliver D. Payton, Neal T. Skipper, Vasiliki Tileli and Christopher A. Howard, explains their happy “accident.” A Happy Accident “Nanoribbons, meanwhile, combine the flexibility and unidirectional properties of one-dimensional nanomaterials, the high surface area of 2D nanomaterials and the electron-confinement and edge effects of both. The structures of nanoribbons can thus lead to exceptional control over electronic band structure, the emergence of novel phenomena and unique architectures for …

$1.50 a Gallon, Carbon-Free, and Maybe?

Gizmag readers responded pretty much equally with hope and skepticism to today’s story on Cella Energy’s announcement of their hydrogen-based, emissions-free fuel that would power your car for $1.50 a gallon.  One asked if it were April 1 yet.  Others held out more charitable views of the announcement, and perhaps deservedly so. Cella’s diagram compares bulky high-pressure storage with room-temperature, ambient-pressure storage solution Cella is partially a spinoff of Oxford University’s ISIS programs, named for the Egyptian goddess of magic and life and overflowing with demonstrated successes.  We’ve reported on their Yokeless And Segmented Armature (YASA™) topology motor, a 34-centimeter (13.4 inches) diameter, 7-centimeter (2.76 inches) thick, 11 kilogram (23.2 pound) marvel that can produce a peak 100 kilowatts and 700 …
