Optimizing Stratification in Binary Colloidal Supraparticles

Advanced Science, EarlyView.
Supraparticles from binary particle populations show stratification when dried at high Péclet numbers. In spray‐dried systems at high initial particle concentration and fast drying conditions optimal combinations of particle size ratios and volume fractions that produce maximal stratification are found both in experiment and simulation, contrasting the

A Pathology‐Instructed Theranostic Platform with Mechanoadaptive and ROS‐Powered Nanobreathing Functions for Precision Myocardial Repair

Advanced Science, EarlyView.
We developed a pH responsive theranostic serum albumin hydrogel named BST, functionalized with MRI and CT probes and loaded with mitochondria targeted CAT‐SOD nanogels, that rapidly self repairs and mechanically stabilizes the infarcted myocardium, releases therapeutic nanogels and albumin under hypoxia induced acidosis to clear mitochondrial ROS ...

A Hydrogen Sulfide–Releasing Dynamic Hydrogel Modulates Coordinated Neurovascular, Immune, and Angiogenic Responses for Scar‐Suppressed Diabetic Wound Repair

Advanced Science, EarlyView.
ROS‐Responsive H2S Hydrogel (HAPPF) Coordinated Regeneration for High‐Quality Diabetic Wound Repair.A self‐regulating dynamic hydrogel is developed to deliver a fluorogenic H2S donor in response to excessive ROS. Released H2S acts as a master regulator to resolve chronic inflammation (M2 polarization), restore VEGF‐driven angiogenesis, and rebalance ...

Bioinspired Passive Flow Routing to Mitigate Thrombosis in Prosthetic Heart Valves and Cardiovascular Devices

Advanced Science, EarlyView.
Bioinspired passive flow routing mitigates thrombosis in cardiovascular devices by redirecting a small fraction of forward flow into stagnation‐prone regions. Inspired by avian alula and aircraft slat mechanisms, strategically placed routing channels restore washout around mechanical heart valves, reducing low‐shear exposure by four orders of magnitude

Direct numerical simulation study on relationship between Ranque-Hilsch effect and turbulence in high-speed swirling flow inside a cylindrical vortex chamber

Nihon Kikai Gakkai ronbunshu
The Ranque-Hilsch vortex tube (RHVT) is a device which can separate compressed gas into high and low energy flows only through its own fluid motion by generating a high-speed swirling flow inside a cylindrical vortex chamber.

Multi‐Stimuli Responsive Magneto‐Coacervate Droplets for Selective Molecular Enrichment and Programmable Manipulation

Advanced Science, EarlyView.
ABSTRACT Coacervate droplets formed via liquid–liquid phase separation offer unique opportunities as microreactors and delivery vehicles due to their ability to selectively concentrate biomolecules and support biochemical reactions. However, their passive nature severely restricts precise spatial and temporal control, posing barriers to practical ...

VISCOUS FLOW MODELING USING THE VORTEX PARTICLES METHOD

TASK Quarterly, 2009
The vortex particle method is an easy and attractive tool to analyze flow phenomena by investigating vorticity fields and the generation of vorticity at solid walls. The vorticity generation at the walls and its introduction to the flow is of fundamental significance for understanding such phenomena as transition to turbulence, boundary layer ...

Efficient Adsorption‐Based Direct Air Capture Via Triply Periodic Minimal Surface Architectures

Advanced Science, EarlyView.
Architected triply periodic minimal surface (TPMS) contactors reshape direct air capture by replacing straight‐channel diffusion limits with convection‐enhanced CO2 transport. Chaotic advection thins boundary layers and exposes fast adsorption sites, enabling 70%–75% more fast sites, 114% higher productivity, and 51.8% lower energy consumption than ...

Advanced numerical investigation of Saffman–Taylor instability in porous media with gas injection and rheological effects

Results in Engineering
The displacement of viscous fluids in porous media often leads to hydrodynamic instabilities, particularly the Saffman–Taylor instability, which reduces sweep efficiency in processes such as enhanced oil recovery, gas injection, and thermal management ...
