The University of Pennsylvania recently finished their newest addition
to the campus, Penn Park, which adds a brilliant contrast to the
Philadelphia skyline and gives multiple sports teams a new place to
practice and engage in athletics.
Professor Alison Sweeney studies bio-optical properties of cephalopods and the cellular and biochemical mechanisms of dynamic camouflage.
The Precision Array for Probing the Epoch of Reionization is a radio interferometer designed to detect 21 cm Hydrogen (HI) fluctuations occuring when the first galaxies ionized intergalactic gas at around 500 million years after the Big Bang. The Penn PAPER team is led by Professor James Aguirre.
Proteins on Carbon Nanotubes
The image shows an example of peptides that assemble into a tubular structure surrouding single-walled carbon nanotubes. The geometrically defined, virus-like coating created by these peptides converts the smooth surfaces of carbon nanotubes into highly textured assemblies with long-scale order, capable of directing the assembly of gold nanoparticles into helical arrays along the nanotube axis.
Self-assembling Building Blocks
Self-assembling building blocks occur in a diverse set of supramolecular, macromolecular, and other complex systems that impact numerous fields such as industrial dyes and pigments, xerographic receptors, organic semiconductors, transistors, light-emitting diodes and solar cells. Prof. Paul Heiney collaborates with chemists and material scientists on the study of such molecular systems.
Cullen Blake, Professor of Physics and
Astronomy, describes the discovery of Proxima Centauri b by a team led by Dr.
Guillem Anglada-Escudé of Queen Mary University in London. This Earth-like
planet is right in our own backyard, orbiting one of the closest stars to our
Sun. Blake hopes that with the help of a new generation of telescopes, we will
be able to learn amazing things about our new neighbor."
Thursday, December 8, the Physics and Astronomy Department will host the second
Annual Women in Physics Public Lecture, to be delivered by Prof. Alessandra
Buonanno, Director at Max Planck Institute for Gravitational Physics. The event
is made possible by a Fund to Encourage Women grant.
Vijay Balasubramanian, Professor of Physics and Astronomy, is a Principal Investigator in the “It from Qubit” project which includes institutions across the United States and in Canada, Israel, Japan, the United Kingdom and Argentina. The project is investigating the idea that the fabric of spacetime is knitted together by quantum entanglement. Utilizing the sciences of quantum computers and the study of space time and general relativity, Vijay hopes to discover the components that make up space time and decode the quantum nature of large-scale events in the cosmos.
