Mildred Dresselhaus, the Queen of Carbon, Dies at 86

THE NEW YORK TIMES | 

Dr. Dresselhaus used resonant magnetic fields and lasers to map out the electronic energy structure of carbon. She investigated the traits that emerge when carbon is interwoven with other materials: Stitch in some alkali metals, for example, and carbon can become a superconductor, in which an electric current meets virtually no resistance.

Dr. Dresselhaus was a pioneer in research on fullerenes, also called buckyballs: soccer-ball-shaped cages of carbon atoms that can be used as drug delivery devices, lubricants, filters and catalysts.

She conceived the idea of rolling a single-layer sheet of carbon atoms into a hollow tube, a notion eventually realized as the nanotube — a versatile structure with the strength of steel but just one ten-thousandth the width of a human hair.

She worked on carbon ribbons, semiconductors, nonplanar monolayers of molybdenum sulfide, and the scattering and vibrational effects of tiny particles introduced into ultrathin wires.

    The Nanotechnology Day (#NationalNanoDay) is an annual celebration created in the US featuring a series of community-led events and activities on or around October 9 to help raise awareness of nanotechnology, how it is currently used in products that enrich our daily lives, and the challenges and opportunities it holds for the future. This date, 10/9, pays homage to the nanometer scale, 10–9 meters.

    Following the provisional resolution of this year's Severo Ochoa Centers of Excellence call, there has been a hustle and bustle in the press and in the social networks regarding the criteria of excellence of the Severo Ochoa programme, and the fact that the ICIQ (Institute of Chemical Research of Catalonia) is not within the selected members.

    "Peter Grünberg was one of the first physicists to understand the potential of nascent nanotechnologies for fundamental research. He discovered giant magnetoresistance, or GMR: a large change in electrical resistance induced by a small magnetic field in stacks of ultrathin magnetic and non-magnetic layers." says Albert Fert* in Peter Grünberg's Obituary in Nature.
