Building Novel Carbon Allotropes
Calculations indicate that a form of carbon synthesized from pentagonal hydrocarbon molecules could have unusual electrical and mechanical properties. Continue reading
Cold, supersaturated urban air could be accelerating pollutant particle growth
A new experiment suggests that ammonium nitrate particles nucleate and quickly grow in winter conditions. Continue reading
Ion Recoil from Photon Beam Observed
Experiments confirm that photonionized molecules get a backward kick, as predicted by theory. Continue reading
Smog-forming particles may grow quickly in supersaturated urban air
Ammonium nitrate particles nucleate and grow in winter-like conditions, according to a new experiment. Continue reading
Seafloor avalanches travel fast and far
Acoustic measurements of sediment concentration quantify the wide-reaching influence of turbidity currents. Continue reading
Unjammed Emulsions Collapse to Liquids
An emulsion’s rigidity disappears when the droplets’ random thermal motion overcomes the confining pressure that binds them. Continue reading
Efficient Detection of Microwave Photons
A new single-photon detector minimizes false positives by ensuring that a qubit switches to its excited state if and only if a photon enters a microwave resonator. Continue reading
Pressure alters rock magnetization
A rock buried in Earth’s crust or a meteorite compressed on impact may end up with increased magnetization. Continue reading
Food residues help date ancient pottery
Radiocarbon dating of carefully extracted fatty-acid compounds could become a robust archaeological tool. Continue reading
Localized electric field manipulates a nuclear spin
The atom-level control could provide the precision required for some quantum computing applications. Continue reading
