Imagine what it was like to take a photograph of an object such as a tree, before the wide availablilty of zoom lenses. You would be able to make out the shape and the branches from a distance but you wouldnt be able to see the smaller branches or leaves. Until recently, Doctors have been in a similar situation regarding NMR (nuclear magnetic resonance) imaging of organs and other features deep within the body. Thanks to a new NMR microscope developed by Oxford Researchers, Doctors will in future be able to focus in with a magnification factor of around x100 on hot spots or areas identified as a potentially life threatening soft tissue disease such as cancer or an aneurysm in order to make a more reliable diagnosis in a more comfortable way for the patient.
The imaging of very small features within the human body using NMR has long been a desirable objective, not only because the images provided using current methods of PET (Positron Emission Tomography) scanning are not detailed enough i.e. they do not allow images of organs or other features deep within the body to be created in enough detail, but also because they involve the use of unpleasant processes such as injecting opaque dyes and time restricted large dose levels of X-rays.
Researchers at Oxford University have developed a waveguide technology which permits the detailed examination of features located at its tip. The tapered pickup allows the collection of very localised signals whilst isolating them from surrounding objects resulting in the possibility of collecting very high resolution MRI data.

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...
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...
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,...
Broadband rotational spectroscopy unravels structural reshaping of isolated molecules in the gas phase to accommodate water

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.
Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
