Novel Algorithms of 3D Particle Tracking Velocimetry Using a Tomographic Reconstruction Technique
Journal of Fluid Science and Technology, 2012 New algorithms of 3D particle tracking velocimetry (3D PTV) based on a tomographic reconstruction approach have been developed and tested by using synthetic images of unsteady 3D flows.

Advanced Optical Materials, Volume 14, Issue 29, 7 August 2026.The particle with high surface hydrophilicity exhibits strong thermophoretic attraction, as its dense hydration layer enhances the role of interfacial water molecules in determining thermophoretic mobility over other ionic effects. This finding elucidates the mechanism underlying the robust thermophoretic accumulation of Escherichia coli in high ...

Mixing‐Driven Defects and Composition Evolution in Multi‐Material Metal Additive Manufacturing
Advanced Science, Volume 13, Issue 45, 13 August 2026.Operando synchrotron X‐ray imaging coupled with high‐fidelity multiphysics modeling uncovers how inter‐material mixing reshapes keyhole dynamics and drives distinct pore‐formation pathways in multi‐material laser powder bed fusion (LPBF). Composition‐dependent instabilities trigger defects, whereas rescanning suppresses porosity and homogenizes Cu ...

Cteno‐Bot: An Untethered Metachronally Swimming Robot With Magnetoactive Propulsors
Advanced Intelligent Systems, Volume 8, Issue 8, August 2026.We present Cteno‐bot, an untethered ctenophore‐inspired robot which swims using metachronally coordinated appendages. A single mechanism controls up to 216 magnetoactive propulsors via a dynamically varying magnetic field. We show that the swimming speed of the robot can be increased without a corresponding increase in power requirement, simply by ...

A PIV-based method to measure spatial gradients in bedload transport over a dune
E3S Web of Conferences, 2018 Traditional sediment transport equations calculate sediment flux from bed shear stress and the equations predict that transport increases nonlinearly with an increase in flow velocity.

Earth Surface Processes and Landforms, Volume 51, Issue 8, August 2026.Physical modelling of macro‐roughness elements for river restoration showed that backwater rise depends mostly on the relative structure width and approaching flow Froude number, with only minor differences among designs. Internal geometry modulated turbulent kinetic energy and flow partition between gap and wake.

, 2015 Among modern airflow measurement methods, Particle Image Velocimetry (PIV) and Particle Tracking Velocimetry (PTV), as visualized and non-instructive measurement techniques, are playing more important role. This paper conducts a comparative experimental study for airflow measurement employing both techniques with the same condition.
