Cavitation Bubbles in a Starting Submerged Water Jet

open access: yes, 2001
The behavior of cavitation bubbles in a starting submerged water jet discharging from a circular nozzle is studied by a simple photography technique in a moderately low range of jet exit velocity.

Characteristics of breaking coal-rock by submerged jet and its application on enhanced coal bed methane recovery

open access: yes, 2019
Hydraulic slotting is a technique to enhance coal bed methane (CBM) recovery and prevent gas disasters. The drilling fields are usually arranged in floor roadway rather than roof roadway, but submerged jet effects caused by hydraulic slotting in roof ...

Bio‐inspired nanophotonics: Structural color, chirality, and resonance metasurfaces

open access: yesInfoMat, EarlyView.
A butterfly‐wing‐inspired anisotropic plasmonic flatband resonant metasurface. Insets, photo of the butterfly, Sasakia charonda, and the SEM image of its wing scale (above); the SEM image of the metasurface (below). Abstract The dazzling colors of butterfly wings and hummingbird feathers are not painted with pigments, but crafted by nature's invisible ...

Impact of abrasive versus non‐abrasive cleaning on peri‐implantitis titanium release: A randomized clinical trial

open access: yesJournal of Periodontology, EarlyView.
Abstract Background Surface decontamination is integral to peri‐implantitis treatment. However, abrasive mechanical methods can cause implant surface degradation with possible adverse biological effects. No human studies have examined whether these treatments cause titanium release or impair regenerative outcomes.

Uncertainty assessment for a novel optically shallow water radiometric acquisition platform

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract We present a novel motorized platform, a custom‐built jet‐ski designed for acoustic and radiometric measurements in optically shallow coastal waters. This platform integrates in‐water radiometers with single‐beam and multi‐beam acoustic sensors, along with a suite of active and passive instruments (conductivity‐temperature‐depth, fluorescence,

Interleaved Diffractive Networks for Information Transfer Through Random Diffusers

open access: yesLaser &Photonics Reviews, EarlyView.
This work presents a cascaded diffractive optical network that enables information transfer through random, unknown diffusers using passive, interleaved structured layers that mitigate scattering without digital computation. A hybrid optical‐digital version further improves robustness and reconstruction fidelity under distortions, with both simulations
