'Nanojuice' could improve how doctors examine the gut
Located deep in the human gut, the small intestine is not easy to examine. X-rays, MRIs and ultrasound images provide snapshots but each suffers limitations. Help is on the way.
Nanoscale composites improve MRI: Researchers merge magnetic particles to detect, fight disease
(Phys.org) —Submicroscopic particles that contain even smaller particles of iron oxide could make magnetic resonance imaging (MRI) a far more powerful tool to detect and fight disease.
Impurity size affects performance of emerging superconductive material
Research from North Carolina State University finds that impurities can hurt performance – or possibly provide benefits – in a key superconductive material that is expected to find use in a host of applications, ...
MRI, on a molecular scale: Team develops system that could peer into atomic structure of individual molecules
For decades, scientists have used techniques such as X-ray crystallography and nuclear magnetic resonance (NMR) imaging to gain invaluable insight into the atomic structure of molecules. Such efforts have ...
Manipulating electron spin mechanically
(Phys.org) —Contrary to many textbook illustrations, electrons aren't just balls floating around an atom. In quantum theory, they're more like little tops, exhibiting "spin," and each creating its own tiny ...
Chemists use MRI to peek at temperatures of gases inside catalytic reactors
UCLA chemists for the first time have employed magnetic resonance imaging (MRI)—a technique normally reserved for medical clinicians peering inside the human body—to better measure the temperature of ...
Synthesis produces new antibiotic: Scientists confirm potent synthesis of natural tetracycline
A fortuitous collaboration at Rice University has led to the total synthesis of a recently discovered natural antibiotic.
New cancer-hunting 'nano-robots' to seek and destroy tumours
It sounds like a scene from a science fiction novel – an army of tiny weaponised robots travelling around a human body, hunting down malignant tumours and destroying them from within.
Chemists develop MRI technique for peeking inside battery-like devices
A team of chemists from New York University and the University of Cambridge has developed a method for examining the inner workings of battery-like devices called supercapacitors, which can be charged up extremely quickly ...
MRI for a quantum simulation
Magnetic resonance imaging (MRI), which is the medical application of nuclear magnetic resonance spectroscopy, is a powerful diagnostic tool. MRI works by resonantly exciting hydrogen atoms and measuring ...
Self-assembling nanoparticle could improve MRI scanning for cancer diagnosis
Scientists have designed a new self-assembling nanoparticle that targets tumours, to help doctors diagnose cancer earlier.
'Compressive sensing' provides new approach to measuring a quantum system
(Phys.org) —In quantum physics, momentum and position are an example of conjugate variables. This means they are connected by Heisenberg's Uncertainty Principle, which says that both quantities cannot be ...
Water caged in buckyballs
In a new paper in the Journal of Chemical Physics, a research team in the United Kingdom and the United States describes how water molecules "caged" in fullerene spheres ("buckyballs") are providing a deep ...
MRI sensor that enables long-term monitoring of oxygen levels could aid cancer diagnosis, treatment
Unlike healthy cells, cancer cells thrive when deprived of oxygen. Tumors in low-oxygen environments tend to be more resistant to therapy and spread more aggressively to other parts of the body.
