Determining Exciton Diffusion Length in Organic Semiconductors: Unifying Macro‐ and Microscopic Perspectives

Advanced Energy Materials, EarlyView.
Exciton diffusion length in organic semiconductor films is determined from encounter/annihilation rates. Non‐normalized exciton densities and proper intrinsic lifetime reference avoid over‐parametrization of the fits. Monte Carlo Simulation of individual molecule‐to‐molecule hops reproduce these results (②) when matching lattice constant and hoping ...

The bright unidentified gamma-ray source 1FGL J1227.9-4852: Can it be associated with an LMXB?

, 2011
We present an analysis of high energy (HE; 0.1-300 GeV) gamma-ray observations of 1FGL J1227.9-4852 with the Fermi Gamma-ray Space Telescope, follow-up radio observations with the Australia Telescope Compact Array, Giant Metrewave Radio Telescope and ...

Design of a Wideband Radio Telescope [PDF]

2007 IEEE Aerospace Conference, 2007
A wideband Radio Telescope is being designed for use in the Goldstone Apple Valley Radio Telescope program. It uses an existing 34-meter antenna retrofitted with a tertiary offset mirror placed at the apex of the main reflector. It can be rotated to use two feeds that cover the 1.2 to 14 GHz band.

A deep survey of the low-surface-brightness radio sky

, 2007
We have made a radio survey--the Australia Telescope Low Brightness Survey (ATLBS)--of 8.4 square degrees sky area, using the Australia Telescope Compact Array in the 20-cm band, in an observing mode designed to provide wide-field images with exceptional

CLASS B0827+525: `Dark lens' or binary radio-loud quasar? [PDF]

, 2000
We present radio, optical, near-infrared and spectroscopic observations of the source B0827+525. We consider this source as the best candidate from the Cosmic Lens All-Sky Survey (CLASS) for a `dark lens' system or binary radio-loud quasar.

Continuous Flow Block Copolymer Nanoaggregate Synthesis and Their Flow Dialysis Purification

Chemistry–Methods, EarlyView.
This work details the methodology for the synthesis of block copolymer nanoparticles through continuous flow self‐assembly and purification via flow dialysis. Nanoaggregates are formed by mixing block copolymer solutions in THF with water, followed by dialysis to eliminate excess solvent.
