The rapid tumbling motions of gas phase molecules, such as those in the air around us, means that at any instant in time, the molecules are pointing in many different directions, and this blurs any image that may be recorded. Now, using a pair of carefully crafted femtosecond laser pulses, a team of researchers at The Open University and the National Research Council of Canada have forced molecules to line up in the same direction to "pose" for a photograph.
When combined with the ultra-fast shutter speeds such as those provided by ultrashort pulses of X-ray light produced at some of the world’s largest facilities, such as the European X-Ray Laser Project XFEL near Hamburg, which is being built to meet just this goal, this technique will allow for sharp images of isolated molecules to be recorded.
This new research “Field-free three-dimensional alignment of polyatomic molecules” is to be published in Physical Review Letters on November 3 2006.
Co-author Dr Jonathan Underwood of The Open University’s Department of Physics and Astronomy says: “This new technique means another of the barriers to understanding the science of our world has been lowered.
This technique will allow us to take photographs in the very near future from which we’ll be able to map the atomic details of molecules as they re-arrange and undergo chemical processes.”

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.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
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...
