“…The pressure owing to the surface stress f of the nanoparticle was expressed using the generalized capillary equation as where Δ p is the volume average of the capillary pressure, A is the area of the surface of the particle, and V is the volume of the particle. Equation can be expressed using bulk modulus, which is K = −(1/ V )(d V /d p ), as follows f can be estimated from eqs and and the reported K value using Δ V / V = ( V particle – V bulk )/ V bulk and A / V. ,, …”

Lattice expansion and surface stress for tetragonal SnO 2 nanorods and nanosheets were systematically investigated using lattice constants determined from in situ synchrotron radiation X-ray powder diffraction of hydrothermal synthesis. A particle size dependence of lattice constants a and c for the nanorods was identical to that for the nanosheets in the same size within experimental uncertainties. The fact suggests the lattice constants of SnO 2 nanostructured materials only depend on the particle size parallel to the crystallographic axis. The average atomic volume of the nanorods and nanosheets linearly depends on the ratio of the particle surface area A to volume V in A/V < 0.5 nm −1 . The surface stress estimated in A/V < 0.5 nm −1 was −1.7(2) N/m with a reasonable average atomic volume for bulk. Significant deviations from the linear line were observed in A/V > 0.5 nm −1 for the nanorods and nanosheets. A boundary of expansion behavior was found to be the particle size of ∼9 nm. The critical length of 9 nm has an effect on the study of their application for Li-ion batteries since SnO 2 nanostructured materials with size from a few nanometers to tens of nanometers have been fabricated and investigated for anodes in lithium-ion batteries.

“…[64,81] The most often used top-down methods for the synthesizing of MNP include ball milling, electron beam deposition, laser ablation, and sputtering, while thermal decomposition, coprecipitation, hydrothermal, and sol-gel techniques have been the most studied bottom-up techniques. [90,[95][96][97] Physical methods are inherently simpler processes that rely on the removal, division, and downsizing of bulk material and are favored for large-scale manufacturing of NP. However, the imperfection of the surface structure and the achievement of suitable characteristics are some of the most significant drawbacks of this route of manufacturing.…”

“…By adjusting laser ablation parameters, it is possible to generate MNP with application-specific properties. [95,96,[98][99][100] Very similar is the sputtering technique, which is mostly used on a semiindustrial and industrial scale. In this case, the MNP are obtained by ejecting atoms from the surface of a bulk target material using plasma, followed by the deposition of the obtained particles onto a substrate.…”

Diverse applications of nanoparticles (NP) have been revolutionary for various industrial sectors worldwide. In particular, magnetic nanoparticles (MNP) have gained great interest because of their applications in specialized medical areas. This review starts with a brief overview of the magnetic behavior of MNP and a short description of their most used synthesis methods. The second part is dedicated to the MNP applications in tissue engineering, emphasizing the calcium phosphate‐based NP with intrinsic magnetic properties, recently highlighted in the literature as alternative and viable solutions for bone regeneration. The challenges associated with the controversial long‐term toxicity effects of MNP can be overcome using this new generation of multifunctional bone‐like magnetic materials. Furthermore, the influence of magnetic field parameters, such as modality of application, intensity, and spatial distribution, on the biological behavior of magnetic materials, especially for bone repair, is shown. The last part of the review presents the current state of the art regarding the development of magnetic biomaterials for additive manufacturing (AM), aiming to fabricate scaffolds by AM technologies, focusing on bone tissue engineering applications.
