Plasmonic Nanomachines: Creating Local Potential Gradients and Motions

Advanced 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 ...

Study of high-resolution analysis of Rayleigh waves on the basis of the Choi–Williams distribution

Frontiers in Earth Science
Rayleigh wave exploration is widely used in the field of engineering investigation, which can analyze the near surface velocity structure. However, the traditional Rayleigh wave exploration data processing method can only provide the average change of ...

Nonlinear Interferometry via Fock State Projection

, 2006
We use a photon-number resolving detector to monitor the photon number distribution of the output of an interferometer, as a function of phase delay. As inputs we use coherent states with mean photon number up to seven.

Truncated Rayleigh Lomax Distribution

, 2023
The Truncated Rayleigh - Lomax distribution is introduced in this research. To do this, we interrupt the period of Rayleigh-Lomax to create a distribution with more flexibility and efficiency. Then we extracted the statistical and mathematical characters of the distribution, like, cumulative distribution, survival, density, Hazard, and cumulative ...

Crack Repair in Hydroxyapatite Bioceramics Using an Ultraviolet Ultrafast Laser

Advanced Materials Interfaces, EarlyView.
The study proposes an ultrafast ultraviolet laser approach to repair hidden tooth cracks, which has been preliminarily validated on HAP. Moreover, this technique aims to strengthen the native enamel structure rather than introducing a foreign filling material.
