Ultrafast Dense Immobilization of Noble Metal Nanoparticles on Customizable Multifunctional Polymer Microspheres for Heterogeneous Catalysis and Multiplexed Biodetection

Advanced Science, EarlyView.
This work proposes a facile co‐assembly strategy to achieve highly uniform and dense immobilization of diverse noble metal nanoparticles onto metastable multifunctional (e.g., magnetic or fluorescent) polymer microspheres, enabling fabrication of complex hierarchical superstructures.

Mimetic Finite Difference Method for Shape Optimization Problems

, 2014
We test the performance of the Mimetic Finite Difference method applied to a wide class of shape optimization problems. Adaptive strategies based on heuristic error indicators are also considered to validate the effectiveness of the numerical scheme.

Mimetic finite difference approximation of quasilinear elliptic problems

Calcolo, 2014
The authors consider the following quasilinear elliptic problem \[ -\mathrm{div} (\kappa (|\nabla u|^2)\nabla u)=f \quad \text{in}\, \Omega, \qquad u=0\quad \text{on}\, \partial \Omega , \tag{1} \] where \(f\) is a given function and \(\Omega\) is an open, bounded set of \(\mathbb{R}^2\) with boundary \(\partial \Omega\).

A Stable Mimetic Finite-Difference Method for Convection-Dominated Diffusion Equations

SIAM Journal on Scientific Computing, 2023
Convection-diffusion equations arise in a variety of applications such as particle transport, electromagnetics, and magnetohydrodynamics. Simulation of the convection-dominated regime for these problems, even with high-fidelity techniques, is particularly challenging due to the presence of sharp boundary layers and shocks causing jumps and ...

Innovative Metasurface Colorimetric Cell‐on‐a‐Chip Sensor for Continuous, Label‐Free, Non‐Destructive Assessment of Intestinal Barrier Dynamics

Advanced Science, EarlyView.
We developed a real‐time, label‐free, high‐throughput cell‐on‐a‐chip system based on a metasurface plasmon resonance colorimetric sensor (MetaSPRCS) to evaluate intestinal barrier function. This platform enables continuous monitoring of cell adhesion, proliferation, and barrier layer formation, disruption, and repair.

Patterns of interspecific variation in labial microarchitecture among anthropoid primates and the evolution of the hominin lips

The Anatomical Record, EarlyView.
Comparative histological and semi‐automated image analysis of primate lips: Masson's trichrome‐stained sagittal sections were segmented to quantify the connective tissue, adipose, and muscular components, enabling interspecific comparisons of labial architecture.

MIMETIC FINITE DIFFERENCE APPROXIMATION OF FLOWS IN FRACTURED POROUS MEDIA

, 2016
We present a possible framework for the numerical simulation of flow in fractured porous media that couples mimetic finite differences for the porous matrix with a finite volume scheme for the flow in the fractures.

Efficient Numerical Framework for Geothermal Energy Production Optimization in Fracture‐Controlled Reservoirs

International Journal for Numerical Methods in Fluids, EarlyView.
We introduce an efficient open‐source numerical framework for the automated search for the placements of injection and production wells in hot fracture‐controlled reservoirs that sustainably optimize geothermal energy production. We model the reservoirs as discrete fracture networks in 3D. The fluid flow and heat transport in the reservoirs are modeled

Exploring the Production of Extracellular Matrix by Astrocytes in Response to Mimetic Traumatic Brain Injury [PDF]

, 2016
Following injury to the central nervous system, extracellular modulations are apparent at the site of injury, often resulting in a glial scar. Astrocytes are mechanosensitive cells, which can create a neuroinhibitory extracellular environment in response
