Anomalous Phonon Softening with Inherent Strain in Wrinkled Monolayer WSe2

open access: yesAdvanced Materials, EarlyView.
This study introduces the first discovery of a new local strain indicator, A2′′(Γ)$A_2^{^{\prime\prime}}( \Gamma )$ mode, for monolayer WSe2‐based excitonic applications including single photon emitter by using tip‐enhanced Raman spectroscopy. The correlative investigation with density functional perturbation theory provides the origin of the anomalous

Wakes in Axial Compressors

The Journal of the Royal Aeronautical Society, 1959
The note in the July Journal by H. Pearson and A. B. McKenzie (p. 415) shows that the flow into an axial compressor is nearly at a constant velocity at all points in the entry plane; and that if a wake of low energy air is fed into it, the compressor reduces the static pressure locally in this wake, in such a way as to tend to preserve constant ...

Surging of Axial Compressors

Aeronautical Quarterly, 1949
It is fairly generally known that if, at any fixed speed of a compressor, either axial or centrifugal, the flow is reduced by throttling the outlet, then a point is eventually reached at which a complete breakdown of the air flow occurs and in most cases an actual flow reversal through the compressor takes place.
