Poiseuille flow in a nanochannel – use of different thermostats [PDF]

, 2007
Poiseuille flow of a liquid in a nano-channel is simulated by molecular dynamics by embedding the fluid particles in a uniform force field. The channel is periodic in y and z directions and along x direction it is bounded by atomic walls.

Bridging the computational gap between mesoscopic and continuum modeling of red blood cells for fully resolved blood flow

, 2019
We present a computational framework for the simulation of blood flow with fully resolved red blood cells (RBCs) using a modular approach that consists of a lattice Boltzmann solver for the blood plasma, a novel finite element based solver for the ...

The microstructure and corrosion resistance of Mg–Zn-0.5Ag-xCa (x=0, 0.5, 1.0, 1.5 wt%) alloys in Hank's solution

Journal of Materials Research and Technology
Due to the excellent biocompatibility of Zn, Ag, and Ca, these elements were chosen for the development of a Mg–Zn–Ag–Ca alloy system for biomedical applications. This study studied the effect of Ca on the microstructure and corrosion behavior of as-cast

Micropatterned Biphasic Printed Electrodes for High‐Fidelity on‐Skin Bioelectronics

Advanced Functional Materials, EarlyView.
Micropatterned biphasic printed electrodes achieve unprecedented skin conformity and low impedance by combining liquid‐metal droplets with microstructured 3D lattices. This scalable approach enables high‐fidelity detection of ECG, EMG, and EEG signals, including alpha rhythms from the forehead, with long‐term comfort and stability.

Different in vitro behavior of two Ca3(PO4)2 based biomaterials, a glass-ceramic and a ceramic, having the same chemical composition

Boletín de la Sociedad Española de Cerámica y Vidrio, 2015
In this work, the influence of the nature of two materials, with the same chemical composition, on their in vitro behavior has been studied. Two routes were used to obtain these materials with the composition 45% CaO, 22% SiO2, 28% P2O5 and 5% MgO (wt.%).

Coalescence of Liquid Drops: Different Models Versus\ud Experiment [PDF]

, 2012
The process of coalescence of two identical liquid drops is simulated numerically in the framework of two essentially different mathematical models, and the results are compared with experimental data on the very early stages of the coalescence process ...
