Colloidal Behavior of Carbonate Particles Microbially Precipitated in Microfluidic Droplets

open access: yesSmall, EarlyView.
In Microbially Induced Calcium Carbonate Precipitation (MICP), ureolytic bacteria trigger calcium carbonate precipitation via pH‐increasing urea hydrolysis. This enzymatically driven reaction induces the colloidal assembly of bacteria and carbonate particles into fractal networks.

On the Computation of the Hausdorff Dimension of the Walrasian Economy: Addendum [PDF]

open access: yes
In a recent paper, Dominique (2009) argues that for a Walrasian economy with m consumers and n goods, the equilibrium set of prices becomes a fractal attractor due to continuous destructions and creations of excess demands. The paper also posits that the

3D Reconstruction of Nanoparticle Distribution in Tumor Spheroids With Volume Electron Microscopy

open access: yesSmall, EarlyView.
Understanding where nanomaterials accumulate within cells is essential for revealing their biological fate and activity. We present a quantitative imaging framework to map nanomaterials and cellular structures in three dimensions. Applied to nanoparticle‐containing tumor spheroids, the approach reveals substantial cell‐to‐cell differences in uptake ...

Unveiling Graphitic Carbon Nitride in Hexagonal Boron Nitride Epitaxy on Sapphire

open access: yesSmall, EarlyView.
Understanding how crystallographic orientation transfers across weakly bonded 2D/3D interfaces is fundamental for van der Waals materials epitaxy. This study reveals that an interfacial graphitic carbon nitride (g‐C3N4) layer plays a pivotal role in aligning hexagonal boron nitride on sapphire.

Microfluidic Molecular Diagnostic Chips: Functional Modules, Integration Strategies, and Emerging Applications

open access: yesSmall Methods, EarlyView.
This comprehensive review delivers an engineering‐centric analysis of microfluidic molecular diagnostic chips, breaking them down into foundational modules from fluid manipulation to bio‐sensing. Beyond chip design, it evaluates sample‐to‐answer integration strategies and commercial readiness levels.

starU‐Net: An enhanced U‐Net architecture with star operation and multi‐view fusion for improved vessel segmentation

open access: yesVIEW, EarlyView.
Low‐contrast capillaries are often missed or fragmented by segmentation models, so we developed a shallow four‐level starU‐Net that combines star operation‐based feature extraction with dynamic snake convolution‐based multi‐view fusion for improved thin vessel continuity.
