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 …

Twisting, Turning and Nailing the Landing

We like to think that our mastery of aerobatics is second to none, but aircraft only achieve a small part of the birds’ ability to hover, swoop, and perch on a target at zero forward airspeed.  Researchers in Switzerland and England, though, are making progress toward deeper emulation of nature’s masters of flight. Our Fine Feathered Drone Dano Floreano and his team of researchers at  Switzerland’s École Polytechnique Fédérale De Lausanne’s (EPFL) Laboratory of Intelligent Systems, obviously spent lots of time observing birds in flight, noting that our avian friends alter their wing configuration to “change direction, increase their speed or counter headwinds.”  Changing wing shape helps birds make near-instantaneous maneuvers. Floreano, attempting to mimic the birds’ movements, helped develop …
