Photothermal bubble: Dynamics, manipulation, and applications

Droplet, EarlyView.
As a versatile platform for bubble manipulation, photothermal techniques empower diverse operations: planar translation by scanning the laser spot, sustained periodic bouncing from competing thermal and hydrodynamic flows, and even guided 3D trajectories achieved by tailoring the heating configuration.

Localized 3D acoustic streaming in microdroplets using high‐frequency micro‐beam IDTs

Droplet, EarlyView.
Miniaturized 160 MHz acoustic microbeam transducers, with a size much smaller than droplets, enable precise localized actuation, generating complex three‐dimensional streaming and tunable particle aggregation. This concept provides high‐resolution, non‐contact fluid manipulation for biosensing, lab‐on‐chip diagnostics, and targeted drug screening ...

Large droplet release

Droplet, EarlyView.
Curved hydrophobic mesh surfaces enable stable release of large droplets exceeding the capillary length. By tuning surface curvature, porosity, and acceleration, oscillatory breakup is suppressed, producing near‐spherical droplets ideal for high‐precision fluid applications and multiphase flow control.

Non‐monotonic jet pinch‐off induced by droplet impact on immiscible liquids

Droplet, EarlyView.
The graphical abstract shows the evolution of the central jet following droplet impact and summarizes the non‐monotonic dependence of the critical Weber number on the dimensionless film thickness and Ohnesorge number. Abstract Droplet impact on immiscible liquids can generate a central jet whose pinch‐off behavior plays a crucial role in many advanced ...

Tuning Colloidal Stability and Photothermal Conversion Efficiency of Graphite Nanofluids via Anionic‐Nonionic Surfactant Engineering

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Graphite nanofluids were stabilized using a mixed SDS/Tween 80 surfactant system. The optimized formulation exhibited enhanced colloidal stability, red‐shifted UV–Vis absorption, and improved photothermal conversion under solar irradiation. Achieving stable dispersion of graphite flakes (GFs) in aqueous media remains a critical challenge in developing ...
