Limits of Non‐invasive Enzymatic Activation by Local Temperature Control

Small, Volume 20, Issue 30, July 25, 2024.
Magnetic nanoparticles with the enzyme sucrose phosphorylase immobilized on their surface act as selective and spatially localized heat sources when exposed to an external alternating magnetic field. The observed enhancement of the catalytic activity correlates with the bulk temperature increase Tbulk, which agrees with the temperature increase Tact ...

A Fluid–Structure Interaction Analysis to Investigate the Influence of Magnetic Fields on Plaque Growth in Stenotic Bifurcated Arteries

Dynamics
A finite element method is employed to examine the impact of a magnetic field on the development of plaque in an artery with stenotic bifurcation. Consistent with existing literature, blood flow is characterized as a Newtonian fluid that is stable ...

Extension of Spin Dephasing Time of Continuously Excited Ensemble Nitrogen Vacancy Centers by Double‐Quantum Ramsey Magnetometry with Spin Bath Driving

physica status solidi (a), Volume 221, Issue 8, April 2024.
Toward highly sensitive nitrogen vacancy (NV) centers‐based diamond magnetometers, a novel continuously excited (CE) measurement is demonstrated including double electron–electron resonance (CE‐DEER) and double‐quantum Ramsey magnetometry with spin‐bath driving (CE‐DQ‐RADOR).

Investigation of Magnetized Casson Nanofluid Flow along Wedge: Gaussian Process Regression

International Journal of Mathematics and Mathematical Sciences, Volume 2024, Issue 1, 2024.
An unsteady two‐dimensional magnetized Casson nanofluid flow model is constructed over a wedge under the effect of thermal radiation and chemical reaction. The multiple slip effects are also assumed near the surface of the wedge along with the convective boundary restrictions.

MHD analysis of couple stress nanofluid through a tapered non-uniform channel with porous media and slip-convective boundary effects

International Journal of Thermofluids
The current research addresses the peristaltic transport mechanism that propels fluid through a conduit through rhythmic contraction and relaxation of the conduit walls, a phenomenon evident in numerous biological systems, including the gastrointestinal ...

Investigation of Heart Valve Dynamics: A Fluid-Structure Interaction Approach

Fluids
This study presents a numerical investigation into the heart valve through a fluid–structure interaction (FSI) framework using a two-dimensional, steady-state, Newtonian flow assumption. While simplified, this approach captures core biomechanical effects

One-parameter group analysis of biomagnetic fluids with magnetic nanoparticles

Journal of Asian Scientific Research
This study aims to investigate heat and mass transport characteristics in biomagnetic fluid flow, where blood is modeled as a biofluid containing spherical CoFe2O4 magnetic particles. A modified form of Tiwary and Das’s hypothesis is employed to incorporate the combined influence of magnetohydrodynamic (MHD) and ferrohydrodynamic (FHD) effects, an ...
