Ni Nanoparticle‐Decorated Reduced Graphene Oxide Hybrids With Tunable Dielectric–Magnetic Synergy for Efficient Microwave Absorption

Electron, EarlyView.
Optimized Ni nanoparticle loading on reduced graphene oxide creates abundant Ni/rGO heterointerfaces, enhancing interfacial polarization, conductive loss, magnetic loss, and impedance matching. The rGO/Ni‐5 hybrid achieves efficient microwave absorption at only 15 wt.% filler loading, delivering a minimum reflection loss of −35.5 dB and an effective ...

Fully automated three‐dimensional deep learning‐based magnetic resonance imaging segmentation of brain cavities in epilepsy surgery

Epilepsia, EarlyView.
Abstract Objective There are several clinical and research applications for determining the amount of brain tissue resected after epilepsy surgery; however, manual segmentation of postoperative magnetic resonance imaging (MRI) is imprecise and time‐consuming.

A Numerical Investigation of the Effects of Piston Bowl Geometry and Spray Angle on Combustion, Performance and Emission of a Diesel Engine

Energy Science &Engineering, EarlyView.
A piston bowl's design and spray angle improve air‐fuel mixing, resulting in more complete combustion and higher efficiency. Ansys Forte 2023 R1 a CFD software was used to analyze the effects of five combustion chamber geometries of cylinder, modified re‐entrant, re‐entrant, double‐stepped, and stepped on engine performance, combustion, and emission ...

Hydrogen‐Enriched Tri‐Fuel Combustion for Low‐Carbon Engines at Medium Engine Load: A Comprehensive CFD Analysis

Energy Science &Engineering, EarlyView.
CFD analysis of a diesel–CH4–H2 tri‐fuel engine shows that increasing hydrogen energy share (HES) enhances mixing and accelerates combustion, improving pressure, efficiency, and reducing CO and soot. At 60% HES, ISFC improves 26.2%, soot drops 95%, while NOx increases due to higher temperatures. ABSTRACT The global commitment to achieve net‐zero carbon

Forced Draught Impact on Externally Venting Flames: An Experimental and Numerical Investigation

Fire and Materials, EarlyView.
ABSTRACT Wind can significantly influence fire development and spread in urban and forest environments causing fatal consequences for the public, the first responders, and the environment. Wind‐driven fires can have a significant impact on structural fires as wind can increase the fire's intensity, development, and flame spread.
