Navigating Gravity: Competing Effects Result in Opposing Taxis for Different Janus Swimmers

Small, EarlyView.
The combined effects of gravity and wall‐induced hydrodynamics on the motion of Janus colloids are investigated. Platinum‐ and copper‐coated silica microswimmers show distinct gravitactic alignment near surfaces due to different hydrodynamic couplings. This distinct gravitactic behavior enables separation of initially mixed active particles.

Aligning Real‐Time Recurrence Computational Fluid Dynamics Simulations with Plant Data for the Ruhrstahl–Heraeus Degassing Process of Steel

steel research international, EarlyView.
Uncertainties exist in computational fluid dynamics (CFD) modeling of complex metallurgical processes, even when partly validated by laboratory experiments. rCFD enables computationally efficient prediction of long‐term RH degassing and can be adapted to vary flow conditions.

Treatment of biodiesel wastewater using ferric chloride and ferric sulfate [PDF]

, 2017
The production of biodiesel through the transesterification method produces a large amount of wastewater that contains high level of chemical oxygen demand (COD) and oil and grease. In this study, coagulation was adopted to treat the biodiesel wastewater.

Control Effectiveness of Vortex Generators in High‐Speed Flows in Off‐Design Conditions

PAMM, Volume 26, Issue 1, March 2026.
ABSTRACT In aerospace transportation and propulsion systems, shock‐induced flow separation has strong detrimental effects on the aerodynamic behavior and performance. To alleviate these effects, separation control is necessary. A commonly pursued approach uses vortex generators (VG) of different design to increase the momentum transfer within the ...

Particle Image Velocimetry in practice

, 2009
Experimental fluid mechanics has for a long time been used to visualize flow phenomenon. An early pioneer was Ludwig Prandtl who used aluminum particles in water flumes to describe the flow in a qualitative manner. In line with the rapid development of Computational Fluid Dynamics, CFD, the need for new validation tools has increased.

A Novel Microfluidic System for 3D Epidermis and Full‐Thickness Skin Growth for Nanoparticle Safety Assessment

Advanced Healthcare Materials, Volume 15, Issue 6, 9 February 2026.
This work presents a novel, dynamically perfused, configurable microfluidic system for epidermis‐only (E and full‐thickness skin (FT SoC) growth, emulating human skin structure and barrier function. Upon TiO2 nanoparticle exposure, the system reveals compromised barrier integrity, reduced metabolic activity, increased permeability, and chemokine‐driven
