Magnetic Properties of Ferritin at Different Levels of Degradation: Implications for MRI‐Based Iron Quantification in the Brain

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Ferritin's iron core exhibits complex magnetic properties, as suggested by magnetometry and Mössbauer spectroscopy, which remain incompletely understood. In particular, the antiferromagnetic inner core could influence the accuracy of iron quantification using MRI and raise concerns about postmortem validation studies involving degraded

Interaction Between Vortex‐Induced Vibrations and Base Vibrations in Piezoelectric Harvesters

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT In the present era, powering sensors using green energy is a significant challenge. One promising solution for the power supply of small sensors relies on piezoelectric energy harvesters excited by vortex‐induced vibrations (VIVs) generated by wind.

The effect of compliance assistance on pollution discharges and violations of environmental regulations

Journal of Policy Analysis and Management, EarlyView.
Abstract Researchers and policymakers assert competing behavioral models of polluters. One model portrays polluters as best approximated by the perfectly informed, rational actor from economics textbooks. Another model portrays polluters, particularly small and medium facilities, as imperfectly informed, cognitively bounded, pro‐social actors.

Low complexity antenna selection for V-BLAST systems with OSIC detection

EURASIP Journal on Wireless Communications and Networking, 2011
Multiple-input multiple-output (MIMO) systems have an advantage of spectral efficiency compared to single-input single-output systems, which means that the MIMO systems have significantly higher data throughput.

What Is a Polyolefin? A Critical Overview of Ethylene Copolymers Used as Solar Photovoltaic Module Encapsulants

Progress in Photovoltaics: Research and Applications, EarlyView.
Polyolefin encapsulants are gaining dominance in PV modules, yet confusion persists around PO, POE, and TPO definitions. This study clarifies terminology, reviews materials, and properties and proposes a taxonomy to improve understanding, communication, and reliability in solar module manufacturing.

Enhanced Low‐Frequency Microwave Absorption and Corrosion Resistance of FeSiAl Using Low‐Melting‐Point Glass Phase Coatings

Rare Metals, EarlyView.
ABSTRACT This study developed a FeSiAl@LMPGP composite material to address the demand for low‐frequency electromagnetic absorption. Through controllable heat treatment, FeSiAl particles and PbO nanoparticles self‐assembled into a high‐density Mott–Schottky heterointerface structure, which exhibited a significant built‐in electric field (BIEF) effect ...

MXene‐Based Electromagnetic Attenuation Materials in Microwave and Terahertz Bands

Rare Metals, EarlyView.
ABSTRACT MXenes exhibit considerable potential for developing high‐performance electromagnetic (EM) shielding and absorption materials operating across microwave and terahertz frequencies, due to their tunable surface chemistry and exceptional charge carrier transport properties.

Coral‐Like Yolk–Shell‐Structured CoNi@Void@C Microspheres for Enhanced Microwave Absorption, Photothermal, Anti‐Corrosion, and Radiation Shielding Properties

Rare Metals, EarlyView.
ABSTRACT Considering the multiple challenges faced by stealth coatings in complex service environments, the development of multifunctional integrated microwave absorbing materials (MAMs) that combine efficient electromagnetic (EM) attenuation with environmental tolerance has become an urgent need. In this work, coral‐like CoNi@Void@C microparticle (MP)

Resource reallocation across successive systemic innovations: How Rolls‐Royce shaped the evolution of the turbojet, turboprop, and turbofan

Strategic Management Journal, EarlyView.
Abstract Research Summary Despite the importance of resource reallocation in shaping a variety of strategic outcomes, strategy scholars have paid only limited attention to the processes by which firms reallocate their resources across successive systemic innovations.
