Vibrational Exfoliation of 2D Materials

Small, EarlyView.
Vibrational energy folds, fractures and exfoliates atomically and molecularly thin materials. Combining experimentation and computational methods, this unique vibrational synthesis pathway is revealed. This process overcomes barriers of existing approaches by processing 1000 g/L dispersions without loss in yield.

Essential Role of Icosahedral Symmetry in the 3D Shape of AuAg Plasmonic Nanostars With High Aspect‐Ratio Legs

Small, EarlyView.
Electron nanodiffraction mapping was used to determine that the 3D leg configuration of branched plasmonic AuAg nanostars is associated with the icosahedral symmetry of the star core, providing a deeper understanding of their growth mechanism and thus paving the way to the development of optimized synthesis protocols targeting optical enhancement ...

Dynamic Behaviour of Bubbles in Oil Under Electrothermal Ageing

High Voltage, EarlyView.
ABSTRACT During long‐term operation of converter transformers, the internal oil–pressboard insulation undergoes irreversible degradation. Partial discharge in the weakened insulation will cause the formation of a large number of bubbles in the insulating oil.

Modelling the Four‐Dimensional Power Line Sag Dynamics by Point Signature in Time‐Series Synthetic‐Aperture Radar Images

High Voltage, EarlyView.
ABSTRACT Power lines in synthetic‐aperture radar (SAR) images are reflected as point signatures, which fluctuate annually in both the azimuth and range directions. A novel framework is proposed in this paper to evaluate the four‐dimensional dynamic status of power line sag using those point signatures in time‐series SAR images.

Approximate resolution convolution function for fitting a dispersion gap measured on a triple‐axis spectrometer

Journal of Applied Crystallography, EarlyView.
An analytical convoluted gap function is presented for fitting either a linear or a quadratic dispersion gap in a constant‐Q cut measured with a focused triple‐axis spectrometer. It outperforms previous methods of fitting a gap, without requiring a full resolution convolution.We present an analytical convoluted gap function for fitting dispersion gaps ...

ORCHESTRATING DIFFERENCE AND SIMILARITY: Black Fungibility, and the Spatial Redrawing of Racial Categories in Spanish Colonial Morocco, Sahara and Guinea

International Journal of Urban and Regional Research, EarlyView.
Abstract In this article I dissect the spatial strategies through which the Spanish attempted to orchestrate both racial difference and similarity in the African colonies of Morocco, Western Sahara and Equatorial Guinea during the first half of the twentieth century.

Geometric Morphometrics Reveal Body Shape Variation in Freshwater Shrimps of the Genus Macrobrachium Lacking a Mandibular Palp (Formerly Pseudopalaemon Sollaud, 1911) (Decapoda: Palaemonidae)

Acta Zoologica, EarlyView.
ABSTRACT Shape variation in the cephalothorax of Macrobrachium species without mandibular palp using geometric morphometrics was used as a tool to support species differentiation and propose new diagnostic characters for taxonomic identification.
