Fractal wire patterns enhance stretchability of electronic devices
'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.
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 ...
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 ...
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, ...
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 ...
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.
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 nanoparticle delivers, tracks cancer drugs
(Phys.org) —UNSW chemical engineers have synthesised a new iron oxide nanoparticle that delivers cancer drugs to cells while simultaneously monitoring the drug release in real time.
A new paradigm for nanoscale resolution MRI has been experimentally achieved
A team from the University of Illinois at Urbana-Champaign and Northwestern University has devised a novel nuclear magnetic resonance imaging (MRI) technique that delivers a roughly 10-nanometer spatial resolution. ...
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 ...
US Congress acts to avert helium shortage
The US Congress, entrenched in a titanic budget battle, managed to come together Thursday to pass legislation that prevents a market shortage of helium.
A natural boost for MRI scans
Magnetic resonance imaging (MRI) is a technique widely used in medicine to create images of internal organs such as the heart, the lungs, the liver and even the brain. Since its invention in 1977, MRI has become a staple ...
