Positronium is a short-lived system in which an electron and its anti-particle are bound together. In 2007, physicists at the University of California, Riverside created molecular positronium, a brand-new substance, in the laboratory. Now they have succeeded in isolating for the first time a sample of spin polarized positronium atoms.
Working with highly sensitive photomultipliers, Indiana University nuclear physicist Hans-Otto Meyer has identified new attributes to a phenomenon called cryogenic electron emission.
Imagine the marriage of hard metals or semiconductors to soft organic or biological products. Picture the strange, wonderful offspring -- hybrid materials never conceived by Mother Nature.
The applications in medicin...
Oxygen is the only elemental molecule which carries an electronic magnetic moment. As a consequence, the different solid phases encountered on cooling show various degrees of magnetic order, and similar behavior is expected under compression.
Physicists of the Max Born Institute in Berlin report in the latest issue of Physical Review Letters that electrons in semiconductor crystals have a negative inertial mass when strongly accelerated in an electric field.
A sphere of crystals for observing the secrets of atomic nuclei such as those formed at the centre of a star will be inaugurated today at the National Laboratories of Legnaro (LNL) of the Istituto Nazionale di Fisica Nuc...
An exotic state of matter that physicists call a "quantum spin-liquid" can be realized by electrons in a honeycomb crystal structure.
An exotic state of matter that physicists call a “quantum spin-liquid” can be realized by electrons in a honeycomb crystal structure. This is shown by scientists from the Universities of Stuttgart and Würzburg, Germany in the “Nature” magazine.
The latest Goodfellow Directory of Metals & Materials is now available to scientists and engineers seeking small quantities of metals, alloys, polymers, ceramics, and composites for basic research, product development and prototyping. The Directory contains details of approximately 50,000 items, including specifics about forms and dimensions; typical analyses; and atomic, physical, electrical, thermal and mechanical properties.
Physicists at New York University have created "handshaking" particles that link together based on their shape rather than randomly. Their work, reported in the latest issue of the journal Nature, marks the first time sc...
