LOFAR: The potential for solar and space weather studies

The Low Frequency array (LOFAR) will be a next generation digital aperture synthesis radio telescope covering the frequency range from 10 to 240MHz. The instrument will feature full polarisation and multi-beaming capability, and is currently in its design phase. This work highlights the solar, heliospheric and space weather applications where LOFAR, with its unique and unprecedented capabilitie...

Core-Shell CdS-Cu₂S Nanorod Array Solar Cells.

As an earth-abundant p-type semiconductor, copper sulfide (Cu2S) is an attractive material for application in photovoltaic devices. However, it suffers from a minority carrier diffusion length that is less than the length required for complete light absorption. Core-shell nanowires and nanorods have the potential to alleviate this difficulty because they decouple the length scales of light abso...

Solar Radio Bursts and Space Weather

Space Weather is the study of the conditions in the solar wind that can affect life on the surface of the Earth, particularly the increasingly technologically sophisticated devices that are part of modern life. Solar radio observations are relevant to such phenomena because they generally originate as events in the solar atmosphere, including flares, coronal mass ejections and shocks, that prod...

Pin-hole array correlation imaging: highly parallel fluorescence correlation spectroscopy.

In this work, we describe pin-hole array correlation imaging, a multipoint version of fluorescence correlation spectroscopy, based upon a stationary Nipkow disk and a high-speed electron multiplying charged coupled detector. We characterize the system and test its performance on a variety of samples, including 40 nm colloids, a fluorescent protein complex, a membrane dye, and a fluorescence fus...
