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.

Im Focus: Interfacial Superconductivity: Magnetic and superconducting order revealed simultaneously

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.

While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Im Focus: Studying fundamental particles in materials

Laser-driving of semimetals allows creating novel quasiparticle states within condensed matter systems and switching between different states on ultrafast time scales

Studying properties of fundamental particles in condensed matter systems is a promising approach to quantum field theory. Quasiparticles offer the opportunity...

Im Focus: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...

Im Focus: How to inflate a hardened concrete shell with a weight of 80 t

At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).

Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...

Im Focus: Bacterial Pac Man molecule snaps at sugar

Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.

The cells of the mouth, nose and intestinal mucosa produce large quantities of a chemical called sialic acid. Many bacteria possess a special transport system...
