Kikuchi ultrafast nanodiffraction in four-dimensional electron microscopy [PDF]
, 2011 Coherent atomic motions in materials can be revealed using time-resolved X-ray and electron Bragg diffraction. Because of the size of the beam used, typically on the micron scale, the detection of nanoscale propagating waves in extended ...

In urban national parks acoustic indices represent avian habitat quality better than avian diversity
Environmental and Sustainability IndicatorsAcoustic indices provide a statistical method to quantify and assess relationships between soundscapes and avian diversity; however, more testing is necessary before acoustic indices are accepted as suitable proxies for biodiversity.

Acoustic indices perform better when applied at ecologically meaningful time and frequency scales
Methods in Ecology and Evolution, 2020 Acoustic indices are increasingly employed in the analysis of soundscapes to ascertain biodiversity value. However, conflicting results and lack of consensus on best practices for their usage has hindered their application in conservation and land‐use ...

Advanced Functional Materials, EarlyView.The hidden role of Cd segregation at grain boundaries is revealed in p‐type Mg3Sb2 by atom probe tomography and other advanced characterizations. Grain boundary Cd enrichment suppresses the SbMg+ hole‐killer formation and lowers potential barriers, enhancing electrical conductivity.
