Article Synopsis
- Researchers developed single crystalline FeCo nanostars using a straightforward organometallic method, which allowed for direct synthesis without needing a complicated seed-mediated growth process.* -
- The nanostars are made up of 8 tetrahedrons and showcase high magnetization levels similar to bulk materials, measured at 235 A·m·kg.* -
- Advanced imaging techniques revealed complex 3D spin configurations influenced by both dipolar and exchange interactions, highlighting how the unique shape of these nanostars can significantly alter their magnetic properties.*
In this work, non-linear ultrasonic wave techniques have been used to detect the onset of micro-cracking due to steel corrosion in model reinforced concrete elements. The specimens were of prismatic shape with a single steel rebar. The corrosion was forced by admixing an appropriate amount of sodium chloride at the moment of preparing the concrete mix, and by the application of an electric field, using a constant current density power source, and making the steel rebar work as the anode, and an external counter-electrode as the cathode.

- * The type of ligands used in the synthesis significantly influenced the reactivity of the precursors and the resulting chemical structure of the nanoparticles.
- * This synthesis method achieved the formation of a B2 short-range order in FeCo nanoparticles without needing any additional annealing process, resulting in strong magnetic properties and successful applications in inductor-based filters.
Article Synopsis
- - The paper focuses on creating high-magnetization porous silicon-based nanocomposites using a controlled method to synthesize ferromagnetic FeCo nanoparticles.
- - The process involves immersing porous silicon in a colloidal solution, with careful optimization of temperature, immersion time, and solvent type for effective results.
- - Characterization revealed a uniform filling of the pores and achieved a high magnetization level of 135 emu/cm, making these composites valuable for applications in data storage, medical devices, catalysis, and electronics.
Background And Objectives: Iron deficiency (ID) is a prevalent condition in patients with ischemic heart disease and heart failure. Little is known about the impact of ID on exercise capacity and quality of life (QoL) in the recovery phase after an acute coronary syndrome (ACS).
Methods: Iron status and its impact on exercise capacity and QoL were prospectively evaluated in 244 patients 30 days after the ACS.
