Part of Aston’s allocation from the Science Research Investment Fund (SRIF) provided around £700,000 funding for the instruments, which have given Aston the most modern surface analysis instruments available in the world today.
The instruments acquired by the Surface Science Group are a Thermo Fisher ESCALAB 250 imaging X-ray Photoelectron Spectrometer (XPS) and a Thermo Fisher MICROLAB 350 imaging Auger Electron Spectrometer (AES).
Prof Sullivan explained: ‘Surface analysis is concerned with the study and measurement of the physical, chemical and compositional properties of the first one to ten atomic layers. It is the surface which forms the boundary between the environment and/or other materials in contact with that solid. Thus the composition and structure of these outermost layers have a profound effect on the properties and performance of materials and systems in an increasingly wide range of technological and nano-technological applications.
‘Instruments such as these have proved invaluable in the examination, characterisation and understanding of the surface properties of metals, glasses, ceramics, polymers and biological materials and in the study of processes such as adhesion, corrosion, oxidation, biological interactions and drug delivery systems.’
The ESCALAB uses a monochromatic X-ray beam to probe the surfaces and gives information and images of the chemical state of atoms in that surface. The MICROLAB uses a very finely focused electron beam to probe the surface.
The instruments will be used by the Surface Science Group in its present research on nano materials and systems, but should also have much wider use for research within the University.
‘We hope that other research groups at Aston will take advantage of the opportunity to use the best surface analytical instrumentation in the UK today. We would also like to help industry with current problems in the development of new products and processes and also attract new industrially funded research programmes,’ explained Prof Sullivan.

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
