Mapping Nanoscale Buckling in Atomically Thin Cr2Ge2Te6

open access: yesAdvanced Functional Materials, EarlyView.
Atomic‐resolution STEM is used to resolve nanoscale buckling in monolayer Cr2Ge2Te₆. A noise‐robust image analysis reconstructs three‐dimensional lattice distortions from single plan‐view images, revealing pronounced defect‐driven nm‐scale out‐of‐plane buckling.

Using sounds and sonifications for astronomy outreach [PDF]

open access: yes, 2008
Good astronomy pictures, like those of the HST, play an important and wellknown role in astronomy outreach, triggering curiosity and interest. This same aim can also be achieved by means of sounds.

Elucidating the Role of Surface Ligands on the Oxidative Etching of Au Bipyramids During Photothermia Using Liquid Cell Transmission Electron Microscopy

open access: yesAdvanced Functional Materials, EarlyView.
Gold bipyramids can act as efficient plasmonic nanoheaters, but they often reshape during laser heating. This study shows that oxygen nanobubbles drive oxidative etching and that surface ligands control stability. CTAB‐ and citrate‐coated particles blunt and lose optical performance, whereas polystyrene sulfonate preserves shape and heating by ...

Determination of the CME core parameters by the spectral characteristics of the fine structure of the associated Type IV burst

open access: yesFrontiers in Astronomy and Space Sciences
The analysis of the Type IV burst and spikes observed on its background on 22 August 2015 in the meter–decameter wavelength range is presented. For the first time, spikes as a fine structure of the Type IV burst were used to determine the temperature (T)

Artificial Intelligence‐Assisted Workflow for Transmission Electron Microscopy: From Data Analysis Automation to Materials Knowledge Unveiling

open access: yesAdvanced Materials, EarlyView.
AI‐Assisted Workflow for (Scanning) Transmission Electron Microscopy: From Data Analysis Automation to Materials Knowledge Unveiling. Abstract (Scanning) transmission electron microscopy ((S)TEM) has significantly advanced materials science but faces challenges in correlating precise atomic structure information with the functional properties of ...

The Murchison Widefield Array [PDF]

open access: yes, 2010
It is shown that the excellent Murchison Radio-astronomy Observatory site allows the Murchison Widefield Array to employ a simple RFI blanking scheme and still calibrate visibilities and form images in the FM radio band.

Radio Afterglows of Gamma Ray Bursts

open access: yes, 2017
This review focuses on the physics of Gamma Ray Bursts probed through their radio afterglow emission. Even though radio band is the least explored of the afterglow spectrum, it has played an important role in the progress of GRB physics, specifically in ...

Asymmetry of the Ferroelectric Phase Transition in BaTiO3

open access: yesAdvanced Materials, EarlyView.
Phase transitions are typically assumed to behave identically in forward and reverse. This work shows that in the ferroelectric material barium titanate this is not true: heating drives an abrupt, first‐order jump, while cooling gives a smooth, continuous change.
