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.

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...
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...
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...
