“…Furthermore, the sample from magnetosomes has the lowest volume concentration value of 0.019%. Another formula in the literature, ILP = SAR/( f∙H 2 ) [ 3 , 4 , 5 , 6 , 7 ], indicates that our samples give a comparable value of this parameter to the other literature data. However, the magnetosome material provides the greatest thermal effect of any of our samples.…”

“…In addition, the bimagnetic NPs can exhibit more interesting properties than single-phase NPs, as shown in the case of cube-like bimagnetic hard/soft (CoFe 2 O 4 /Fe 3 O 4 ) and soft/hard (Fe 3 O 4 /CoFe 2 O 4 ) nanocomposites (core/coating) with an average dimension of 20 nm. The CoFe 2 O 4 /Fe 3 O 4 nanocomposites presented a larger saturation magnetization than the CoFe 2 O 4 NPs, which is effective for their potential use in magnetic hyperthermia [ 7 ]. In general, the basic requirement is to achieve maximum heating of a unit amount of magnetic substance per unit time under the conditions of the applied magnetic field at a given frequency.…”

Tuning of Magnetic Hyperthermia Response in the Systems Containing Magnetosomes

A number of materials are studied in the field of magnetic hyperthermia. In general, the most promising ones appear to be iron oxide particle nanosystems. This is also indicated in some clinical trial studies where iron-based oxides were used. On the other hand, the type of material itself provides a number of variations on how to tune hyperthermia indicators. In this paper, magnetite nanoparticles in various forms were analyzed. The nanoparticles differed in the core size as well as in the form of their arrangement. The arrangement was determined by the nature of the surfactant. The individual particles were covered chemically by dextran; in the case of chain-like particles, they were encapsulated naturally in a lipid bilayer. It was shown that in the case of chain-like nanoparticles, except for relaxation, a contribution from magnetic hysteresis to the heating process also appears. The influence of the chosen methodology of magnetic field generation was also analyzed. In addition, the influence of the chosen methodology of magnetic field generation was analyzed. The application of a rotating magnetic field was shown to be more efficient in generating heat than the application of an alternating magnetic field. However, the degree of efficiency depended on the arrangement of the magnetite nanoparticles. The difference in the efficiency of the rotating magnetic field versus the alternating magnetic field was much more pronounced for individual nanoparticles (in the form of a magnetic fluid) than for systems containing chain nanoparticles (magnetosomes and a mix of magnetic fluid with magnetosomes in a ratio 1:1).

“…Besides IONPs, CoFe 2 O 4 (CFO), is the other popular ferrite material exploited for a variety of applications due to its strong intrinsic magnetocrystalline anisotropy, excellent mechanical toughness, and mild magnetic saturation. [ 213 ] In another aspect, the high magnetostrictiveness of CFO particles enables them to change form or size once they are magnetized. [ 214 ] These changes are beneficial in achieving the desired magnetomechanical/electrical response of the scaffold and CFO was thus incorporated into the matrix of piezoelectric polymers.…”

Physical cues like morphology, light, electric signal, mechanic signal, magnetic signal, and heat can be used as alternative regulators for expensive but short‐acting growth factors in bone tissue engineering to promote osteogenic differentiation and bone regeneration. As physical stimulation applied directly to the tissue cannot be focused on the bone defect area to regulate the cell behaviors and fate in situ, this limits the efficiency of precise bone regeneration. Biomaterials‐mediated in situ physical cues, as an effective strategy combining the synergistic effect of materials themselves, are put forward and studied widely to promote osteogenic differentiation and bone repair efficiently and precisely. Different types of physical cues provide different choices to better satisfy the requirements for targeted bone defect repair. In this review, the recent research about different biomaterials‐mediated physical cues accelerating osteogenesis in vitro and promoting in situ bone formation in vivo is introduced. Meanwhile, the corresponding possible mechanisms of various physical cues regulating cell responses are also discussed. This review provides useful and enlightening guidance for the utilization of intrinsically physical properties of functional materials to achieve efficient bone regeneration, leading to the design and construction of smart biomaterials for practical applications, and eventually promoting clinical translation.

“…[40,41] For a knowledge based design of hard carbon anodes, the impact of structural factors such as porosity, carbon binding motifs, and even heteroatom concentration on the functionality of the material must be understood. [42][43][44] While there have been several theoretical studies regarding the role of defects in graphitic systems, defect types, and their functionality have not been thoroughly considered in these investigations. [45][46][47] Therefore, by investigating the impact of defects on the alkali metal storage mechanisms, we have made a first step towards such an understanding.…”

Due to its negligible capacity with respect to sodium intercalation, graphite is not suited as anode material for sodium ion batteries. Hard carbon materials, on the other hand, provide reasonably high capacities at low insertion potential, making them a promising anode materials for sodium (and potassium) ion batteries. The particular nanostructure of these functionalized carbon‐based materials has been found to be crucially linked to the material performance. However, there is still a lack of understanding with respect to the functional role of structural units, such as defects, for intercalation and storage. To overcome these problems, the intercalation of Li, Na, and K in graphitic model structures with distinct defect configurations has been investigated by density functional theory. The calculations confirm that defects are able to stabilize intercalation of larger alkali metal contents. At the same time, it is shown that a combination of phonon and band structure calculations are able to explain characteristic Raman features typically observed for alkali metal intercalation in hard carbon, furthermore allowing for the quantification of the alkali metal intercalation inbetween the layers of hard carbon anodes.
