Prize allows York scientist to go to extremes

07.12.2006
For the next two years, scientist Dr Lucy Carpenter will be taking her study of atmospheric chemistry to climatic extremes, thanks to a Philip Leverhulme Prize

The senior lecturer in the Department of Chemistry at the University of York is already involved in a unique monitoring station in the Tropics, and the £70,000 Leverhulme Prize will allow her to lead a new project in the Arctic.

The International Polar Year project will examine the atmospheric effect of frost-flowers, the delicate ice crystals that form on sea ice and emit halogens, bromine and iodine, into the atmosphere.

Scientists from the UK, Germany and Canada will test the theory that the combination of high surface area and high salinity in the frost flowers leads to the release of the halogens, which then interact resulting in the depletion of ozone and mercury in the troposphere.

Dr Carpenter said the project would be based at a Canadian research station in Hudson Bay for two months in spring 2008 with the team working in an air-conditioned portable laboratory.

“It’s a big field experiment which is going to be logistically very difficult to do. We have to go out there in February and March because of the combination of cold temperatures and sunlight, so I shall spend some of the Prize on teaching relief,” she said.

“We are hoping for temperatures of minus 20 to 30 degrees Celsius -- there are huge floats of frost flowers in those conditions. Our overall aim is to develop an improved understanding of Arctic chemistry and emissions, and their effect and feedbacks on atmospheric chemistry and climate””.

The Arctic project will run in parallel with the Dr Carpenter’s work at the atmospheric monitoring station established in September on the Cape Verde Islands in the Atlantic. With German scientists at a nearby oceanography station, she is studying how atmospheric chemistry affects the ocean and vice-versa.

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
