“…Nanomaterials such as graphene, silicene, germanene, nanotubes, and nanoparticles thanks to their novel intrinsic properties have attracted the attention of researchers from both academic and industrial sectors in the chemical, environmental, optoelectronic, and medical fields [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 ]. An important place among them belongs to magnetite nanoparticles (Fe 3 O 4 ), which show application potential, especially in nanomedicine in magnetic resonance imaging, hyperthermia, targeted drug delivery, enzyme immobilization, cell labeling, separation and purification of biomolecules, and in enrichment of DNA [ 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 ].…”

An adsorption process of magnetite nanoparticles functionalized with aminated chitosan (Fe3O4-AChit) showing application potential in nanomedicine into cell membrane models was studied. The cell membrane models were formed using a Langmuir technique from three selected phospholipids with different polar head-groups as well as length and carbon saturation of alkyl chains. The research presented in this work reveals the existence of membrane model composition-dependent regulation of phospholipid-nanoparticle interactions. The influence of the positively charged Fe3O4-AChit nanoparticles on a Langmuir film stability, phase state, and textures is much greater in the case of these formed by negatively charged 1,2-dipalmitoyl-sn-glycero-3-phospho-rac-(1-glycerol) (DPPG) than those created by zwitterionic 1,2-distearoyl-sn-glycero-3-phosphocholine (DSPC) and 2-oleoyl-1-palmitoyl-sn-glycero-3-phosphocholine (POPC). The adsorption kinetics recorded during penetration experiments show that this effect is caused by the strongest adsorption of the investigated nanoparticles into the DPPG monolayer driven very likely by the electrostatic attraction. The differences in the adsorption strength of the Fe3O4-AChit nanoparticles into the Langmuir films formed by the phosphatidylcholines were also observed. The nanoparticles adsorbed more easily into more loosely packed POPC monolayer.

“…The large spin-splitting of the second band comes from the d-orbitals, whereas the first conduction band with a high d-orbital contribution shows a small splitting. The spinsplitting can be explained by the atomic SOC Hamiltonian as [36,37]:…”

In this work, the electrical and spin properties of monolayer MoSi 2 X 4 (X = N, P, As, and Sb) under vertical strain are investigated. The band structures show that MoSi 2 N 4 is an indirect semiconductor, whereas other compounds are direct semiconductors. The vertical strain has been selected to modify the electrical properties. The bandgap shows a maximum and decreases for both tensile and compressive strains. The valence band at K-point displays a large spin-splitting, whereas the conduction band has a negligible splitting. On the other hand, the second conduction band has a large spin-splitting and moves down under vertical strain which leads to a large spin-splitting in both conduction and valence bands edges. The projected density of states along with the projected band structure clarifies the origin of these large spin-splittings. These three spin-splittings can be controlled by vertical strain.

“…Consequently, if such bonds are formed, the resulting loss of symmetry enables p x –p y coupling to generate non-vanishing 〈 L̂ z 〉, with the extent of splitting predominantly contingent on the atomic SOI of the adsorbate. Consequently, this relationship between symmetry, surface bonding, and SOI has facilitated the same type of GSS in materials such as Tl/Si(111)-1 × 1, 37 Pb/Ge(111)-1 × 1, 76 Pb/germanene, 65 and X/silicene (X = Tl, Pb, Bi). 66…”

[64][65][66][67][68][69][70][71][72] To facilitate the ongoing efforts, it is crucial to develop more robust strategies for enhancing spin splitting. Clear guiding principles need to be established to design materials with desired GSS.…”
