Magnetic Field Control Using an Electromagnetic Actuation System with Combined Air‐Core and Metal‐Core Coils

open access: yesAdvanced Intelligent Systems, Volume 7, Issue 3, March 2025.
An electromagnetic manipulation system enhances magnetic field strength in the Z‐direction for 3D control of microrobots and nanoparticles. Featuring eight metal‐core coils and two air‐core coils arranged hemispherically, it ensures unimpeded workspace access and integrates imaging tools.

Recent advances in boosting interfacial bubble dynamics with external fields

open access: yesDroplet, EarlyView.
External physical fields, including acoustic, magnetic, thermal, mechanical, and optical stimuli, accelerate the entire bubble‐dynamics sequence of nucleation, growth, and detachment. Abstract The efficiency of industrial electrocatalytic reactions depends not only on generating gaseous products but also on their detachment from the catalyst surface ...

The Impact of Obesity on Durable Left Ventricular Assist Device Implantation: A Systematic Review and Meta‐Analysis

open access: yesArtificial Organs, EarlyView.
14 100 LVAD patients across 21 studies were analyzed. Findings indicated that obese LVAD recipients had lower short‐term mortality and higher risk of infection, thrombosis and right heart failure. There was no difference in long‐term survival between obese and non‐obese patients.
