New technique speeds nanoMRI imaging

Multiplexing technique for nanoscale magnetic resonance imaging cuts normal scan time from two weeks to two days

01-Jun-2015

NanoMRI is a scanning technique that produces nondestructive, high-resolution 3-D images of nanoscale objects, and it promises to become a powerful tool for researchers and companies exploring the shape and function of biological materials such as viruses and cells in much the same way as ...

Researchers theoretically demonstrate detection of spin of atoms at room temperature

15-May-2015

For the first time, a researcher at the University of Waterloo has theoretically demonstrated that it is possible to detect a single nuclear spin at room temperature, which could pave the way for new approaches to medical diagnostics.Published in Nature nanotechnology this week, Amir Yacoby from ...

Illinois researchers combine weak chemical forces to strengthen novel imaging technology

A new nanoparticle design, inspired by cell membranes, has led to clearer MRI images and paved the way for better diagnostic tools

26-May-2014

When University of Illinois Associate Professor of Chemical and Biomolecular Engineering Hyunjoon Kong, graduate student Cartney Smith, and colleagues set out to improve MR imaging (MRI), they turned current contrast agent technology on its head —or rather, they turned it inside out. The new ...

MRI, on a molecular scale

Researchers develop system that could one day peer into the atomic structure of individual molecules

23-Apr-2014

For decades, scientists have used techniques like X-ray crystallography and nuclear magnetic resonance imaging (NMR) to gain invaluable insight into the atomic structure of molecules, but such efforts have long been hampered by the fact that they demand large quantities of a specific molecule and ...

RAMBO a small but powerful magnet

Rice University system allows high-magnetic-field experiments on a tabletop

08-Jan-2014

Rice University scientists have pioneered a tabletop magnetic pulse generator that does the work of a room-sized machine – and more. The device dubbed “RAMBO” – short for Rice Advanced Magnet with Broadband Optics – will allow researchers who visit the university to run spectroscopy-based ...

Moving the MRI goalposts

28-Nov-2013

Scientists in the UK have developed a new class of MRI (magnetic resonance imaging) agents that promise to deliver clearer images more quickly. Chemical shifts from proton NMR normally fall between 0-12ppm, but water and fat resonate at 4.7 and 1.3ppm respectively, causing noise that can overlap ...

Control scheme dynamically maintains unstable quantum system

02-Sep-2013

A simple pendulum has two equilibrium points: hanging in the "down" position and perfectly inverted in the "up" position. While the "down" position is a stable equilibrium, the inverted position is definitely not stable. Any infinitesimal deviation from perfectly inverted is enough to cause the ...

Real-time manipulation and control of nuclear spin noise

27-Aug-2013

Basel Physicists in collaboration with Dutch researchers have demonstrated a new method for polarizing nuclear spins in extremely small samples. By Monitoring and controlling spin fluctuations, the method may provide a route for enhancing the resolution of magnetic resonance imaging (MRI) on the ...

Increased NMR/MRI sensitivity through hyperpolarization of nuclei in diamond

07-Jun-2013

Today's nuclear magnetic resonance (NMR) and Magnetic Resonance Imaging (MRI) technologies, like quantum information processing and nuclear spintronic technologies, are based on an intrinsic quantum property of electrons and atomic nuclei called "spin." Electrons and nuclei can act like tiny bar ...

Core facilities: Widening access to research instrumentation

DFG to fund 10 additional projects

30-Apr-2013

The Deutsche Forschungsgemeinschaft (DFG, German Research Foundation) has approved funding for ten additional core facilities to make existing research instrumentation more easily and efficiently accessible to researchers. This decision was made by the DFG's Joint Committee. The projects will ...
