Plasmonic Nanomachines: Creating Local Potential Gradients and Motions

open access: yesAdvanced Materials, EarlyView.
Plasmonic nanomachines can generate optical, thermal, and chemical potential gradients to drive directional rectilinear, rotational, and twisting motions at the nanometer scale. The integration of multimodal plasmonic forces with functional materials and programmed structural distortions enables precise spatiotemporal actuation, thereby providing a ...

A numerical and experimental study of oblique impact of ultra-high pressure abrasive water jet

open access: yesAdvances in Mechanical Engineering, 2016
An investigation of the abrasive water jet with an emphasis on the oblique impact of abrasive particles on the target plate is performed. Ultra-high jet pressure necessitates a close examination of the phenomena featured by small spatial and temporal ...

Reduction of Wave Overtopping and Force Impact at Harbor Quays Due to Very Oblique Waves

open access: yesJournal of Marine Science and Engineering, 2020
Physical model experiments were conducted in a wave tank at Flanders Hydraulics Research, Antwerp, Belgium, to characterize the wave overtopping and impact force on vertical quay walls and sloping sea dike (1:2.5) under very oblique wave attack (angle ...

Type of residual astigmatism and uncorrected visual acuity in pseudophakic eyes

open access: yesScientific Reports, 2022
It is difficult to assess the pure impact of the type of residual astigmatism (with-the-rule; WTR, against-the-rule; ATR, and oblique astigmatism) on uncorrected distance visual acuity (UDVA) in pseudophakic eyes due to different age distribution of ...

Direct Mode‐Resolved Measurement of Interfacial Phonon Transport by Acoustic Phonon Reflectometry

open access: yesAdvanced Materials Interfaces, EarlyView.
We introduce a novel analysis, acoustic phonon reflectometry, that measures the mode‐resolved phonon reflection coefficient at semiconductor interfaces. In aluminum nitride, we observe excellent agreement with the acoustic mismatch model across three distinct interfaces.

Modeling and Nonlinear Response of the Cam-Follower Oblique-Impact System

open access: yesDiscrete Dynamics in Nature and Society, 2016
In order to quickly and accurately analyze the complex behavior of cam-follower oblique-impact system, a mathematical model which can describe separation, impact, and contact was established in this paper.
