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.

Linguistic Variation across Instructional Segments in International Teaching Assistants' Discourse: A Corpus‐Based Analysis

TESOL Quarterly, EarlyView.
Abstract This study investigates internal linguistic variation in the instructional discourse of international teaching assistants (ITAs) by segmenting their mini‐lecture performances into four discourse types: introduction, lecture, conclusion, and audience interaction.

The Crystal Structures of High‐ and Low‐Temperature Silver Pyrophosphate: Structural Instability and Its Consequences

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
The crystal structures of the high‐temperature and low‐temperature phases of silver pyrophosphate are reported. The structural results are complemented by thermal analysis, vibrational and 31P‐MAS‐NMR spectroscopy studies, and density functional theory calculations.

Wavefront sensing at a high‐repetition‐rate X‐ray free‐electron laser

Journal of Synchrotron Radiation, EarlyView.
We demonstrate a fast, robust and sensor‐free approach to X‐ray speckle tracking that enables shot‐to‐shot wavefront characterization at high‐repetition‐rate X‐ray free‐electron lasers. Our measurements reveal a hierarchy of wavefront fluctuations indicative of instabilities in the accelerator and beamline optics at the European XFEL.Wavefront ...

Effects of organic solvents on the depth‐of‐cure determination of conventional and bulk‐fill resin composites

European Journal of Oral Sciences, EarlyView.
Abstract This study investigated the influence of organic solvents on the depth of cure (DOC) of resin composites. Two conventional (Filtek Universal [FU] and Beautifil II [BE]) and two bulk‐fill (Filtek One Bulk Fill [FO] and Beautifil‐Bulk [BB]) composites were evaluated.

Triple Oxygen Isotope Compositions of Isotopic Reference Waters: Implications for VSMOW‐Scale and VSMOW–SLAP‐Scale Δ′17O Calibration

Geostandards and Geoanalytical Research, EarlyView.
Key Points Triple oxygen isotope ratios of two primary (VSMOW, SLAP) and twelve secondary water isotopic reference materials were precisely measured using BrF5 fluorination‐IRMS. The measured Δ'17OVSMOW value for SLAP (34 ± 6 per meg) demonstrates that VSMOW‐SLAP normalisation ensures interlaboratory comparability, but introduces systematic offsets for
