PHILADELPHIA — Directed assembly is a growing field of research in nanotechnology in which scientists and engineers aim to manufacture structures on the smallest scales without having to individually manipulate each component. Rather, they set out precisely defined starting conditions and let the physics and chemistry that govern those components do the rest.
PHILADELPHIA — The field of metamaterials involves augmenting materials with specially designed patterns, enabling those materials to manipulate electromagnetic waves and fields in previously impossible ways. Now, researchers from the University of Pennsylvania have come up with a theory for moving this phenomenon onto the quantum scale, laying out blueprints for materials where electrons have nearly zero effective mass.
Such materials could make for faster circuits with novel properties.
PHILADELPHIA — In the waning days of 2012, two words have dominated the post-election discourse: “fiscal cliff.” The cliff is a combination of impending budgetary measures that will take effect in January if a legislative compromise is not reached.
One area of the budget that would see serious cuts is funding for the national science agencies, such as the National Institutes of Health and National Science Foundation. Combined with cuts to other agencies and departments, the amount of research and development funding lost could total $58 billion over five years.
PHILADELPHIA — Learning calculus is no easy feat. But beginning next month, the University of Pennsylvania’s Robert Ghrist will use a new, visually stimulating approach to engage tens of thousands of students in the task with a massive open online course, or MOOC, offered through Coursera’s online platform.
PHILADELPHIA — One of the most promising innovations of nanotechnology has been the ability to perform rapid nanofabrication using nanometer-scale tips. Heating such tips can dramatically increase fabrication speeds, but high speed and high temperature have been known to blunt their atomically sharp points.
