(PhysOrg.com) -- One of the more challenging fields of scientific inquiry is planetary formation – and most relevant is that of our own Earth and Moon. The current view, based on chronometry (scientific time measurement) ...
(PhysOrg.com) -- Double-core-hole (DCH) states – in which two electrons are ejected from their positions, creating vacancies – occurring at different atomic sites are very sensitive to the chemical environment of ...
(PhysOrg.com) -- While geological evidence points to the presence of liquid water on Mars during the Noachian epoch (the period from 4.5 to 3.5 billion years ago), determining the temperature of that water – a factor ...
(PhysOrg.com) -- Subatomic events can be remarkably counterintuitive. Such is the case in theoretical physics when, under certain specific conditions, atoms exposed to intense infrared laser pulses remain stable rather than ...
(PhysOrg.com) -- Light has its limitations – in this case not velocity, but rather its diffraction limit, which determines the spatial interaction volume in all implementations of optical spectroscopy and is in general ...
(PhysOrg.com) -- Einstein infamously dismissed quantum entanglement as spooky action at a distance and quantum uncertainty with his quip that God does not play dice with the universe. Aside from revealing his conceptual prejudices, ...
(PhysOrg.com) -- Historically, the interior surface of single-walled carbon nanotubes (SWNTs) has not been considered to be chemically reactive. Recently, however, researchers at the University of Nottingham School of Chemistry ...
(PhysOrg.com) -- Since the first optical microscopes appeared in the late 1600s – an exact date and original inventor elude precise identification – microscopy has evolved dramatically. Scanning tunneling microscopy ...
(PhysOrg.com) -- Water is essential to more than its myriad roles in biological, chemical, geological, and other physical processes. Having a precise description of water’s structure is critical to constructing accurate ...
(PhysOrg.com) -- Gene therapy is medicine’s rising star with adeno-associated virus (AAV) vectors – nonpathogenic parvoviruses – among the most promising supporting actors, due largely to their capability to ...
