Isolating an elusive phosphatetrahedrane
A research team in the Department of Chemistry at the Massachusetts Institute of Technology (MIT), Cambridge U.S., explored a synthetic pathway to generate a phosphatetrahedrane framework. During the synthetic route, the ...
Crystal pattern mapping can recover obliterated serial numbers in metals
Researchers at the National Institute of Standards and Technology have demonstrated a technique for mapping deformation in metals that can recover destroyed serial numbers on metal objects such as firearms, a common challenge ...

Seeing smaller through cells: A natural single-cell biomagnifier for subwavelength imaging
Optical microscopes and tweezers can image and manipulate objects at the microscale for applications in cellular and molecular biology. The optical resolution is, however, hampered by the diffraction limit and therefore both ...
Nanomaterial from the Middle Ages
To gild sculptures in the late Middle Ages, artists often applied ultra-thin gold foil supported by a silver base layer. For the first time, scientists at the Paul Scherrer Institute PSI have managed to produce nanoscale ...

Local icosahedral order in metallic glasses
(Phys.org) —Metallic glasses are essentially a frozen, supercooled liquid. They are amorphous metals, often alloys, which are non-crystalline and therefore have a highly disordered atomic arrangement. They are true glasses ...
Research enhances enzyme that degrades plastic
Since it was discovered, the enzyme known as PETase has drawn a great deal of scientific interest for its capacity of digesting PET (polyethylene terephthalate).
