Berkeley Researchers Develop Technique For Imaging Individual Carbon Nanotubes

Despite their almost incomprehensibly small size – a diameter about one ten-thousandth the thickness of a human hair – single-walled carbon nanotubes come in a plethora of different “species,” each with its own structure and unique combination of electronic and optical properties. Characterizing the structure and properties of an individual carbon nanotube has involved a lot of guesswork – until now.

Researchers with the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California (UC) Berkeley have developed a technique that can be used to identify the structure of an individual carbon nanotube and characterize its electronic and optical properties in a functional device.

In his recently published book, Family Consequences of Children’s Disabilities, Dennis Hogan offers the first comprehensive account of families of children with disabilities. He talked with Courtney Coelho about his findings, including some of the more surprising ways having a child with a disability can affect the family structure.

Families of children with disabilities often face a plethora of challenges, ranging from the financial to the emotional. Still, little research has been done to document exactly how families are affected by a child with a disablity. Dennis Hogan’s recently published book, Family Consequences of Children’s Disabilities (Russell Sage Foundation), is the first comprehensive account of these experiences. Motivated by his own experience of growing up with a brother with Down syndrome, Hogan, the Robert E. Turner Distinguished Professor of Population Studies, merged existing data with interviews with more than two dozen family members of disabled children. He talked with Courtney Coelho about his findings, including some of the more surprising ways having a child with a disability can affect the family structure. (more…)
