Stagnation-point flow over a stretching/shrinking sheet in a porous medium [PDF]

open access: yes, 2013
An analysis is performed for the stagnation-point flow over a stretching/shrinking sheet in a porous medium. By using similarity variables, the governing system of partial differential equations are reduced to the coupled ordinary differential equations ...

Characterization of Droplet Formation in Ultrasonic Spray Coating: Influence of Ink Formulation Using Phase Doppler Anemometry and Machine Learning

open access: yesAdvanced Materials Technologies, EarlyView.
This study explores how machine learning models, trained on small experimental datasets obtained via Phase Doppler Anemometry (PDA), can accurately predict droplet size (D32) in ultrasonic spray coating (USSC). By capturing the influence of ink complexity (solvent, polymer, nanoparticles), power, and flow rate, the model enables precise droplet control

NARFL Knockout Triggers Ferroptosis‐Driven Vascular Endothelial Dysfunction

open access: yesAdvanced Science, EarlyView.
NARFL is vital for CIA and oxidative stress resistance. NARFL deletion in HPMEC cells, zebrafish, and mice is lethal and rescued by a Ferroptosis inhibitor. NARFL deficiency disrupted its interaction with CIA proteins, decreased aconitase activity, increased IRP1 activity, induced Fe overload, and led to ferroptosis and oxidative stress, resulting in ...

Richardson's pair diffusion and the stagnation point structure of turbulence [PDF]

open access: yes, 2002
DNS and laboratory experiments show that the spatial distribution of straining stagnation points in homogeneous isotropic 3D turbulence has a fractal structure with dimension D_s = 2.

OPTRACE: Optical Imaging–Guided Transplantation and Tracking of Cells in the Mouse Brain

open access: yesAdvanced Science, EarlyView.
OPTRACE establishes an optical, two‐step platform for intracerebral cell therapy. Transparent glass pipettes enable real‐time, image‐guided delivery, while multiplex genetic labeling with two‐photon and bioluminescence readouts supports longitudinal single‐cell tracking and host–graft dynamics.

Nanoconfinement‐Steered Molecular Preorganization Enables Efficient Monoethanolamine Degradation through Electronically Modulated High‐Valent Iron–Oxo Pathways

open access: yesAdvanced Science, EarlyView.
Precise modulation of reaction pathways remains an unresolved challenge in peroxymonosulfate‐activated advanced oxidation processes. The spatial preorganization strategy in engineered confinement architecture enables regioselective bond cleavage in monoethanolamine via synergistic proton–electron transfer, redirecting its degradation from nonselective ...

Stagnation point reverse flow combustor [PDF]

open access: yes, 2008
A method for combusting a combustible fuel includes providing a vessel having an opening near a proximate end and a closed distal end defining a combustion chamber. A combustible reactants mixture is presented into the combustion chamber. The combustible

Miniature Robotic Swimmer with Precise 2D Motion Control via Acoustic Vortex‐Induced Propulsion

open access: yesAdvanced Science, EarlyView.
In this work, a miniature robotic swimmer achieves precise 2D motion using sound waves with customized 3D‐printed lenses. Localized acoustic vortices drive both translation and rotation of the swimmer without mechanical parts. This contactless approach offers a novel route to controlled micro‐scale movement, with promising applications in biomedical ...
