Summary: This study investigates the influence of different solvent ratios (hexane, toluene, and chloroform) on charge formation in EPD systems. The results show that increasing the ratio of toluene to hexane leads to thicker and rougher NP films, while increasing the ratio of chloroform to hexane reduces film thickness significantly. Solvent choice plays a key role in determining the morphology and processability of NP films fabricated via EPD.

Summary: The objective of this study was to develop simple and easy methods to prepare polymorphic HfO2 thin film materials with the best balance of patterning potential, reproducibility and stability. Nanostructured HfO2 thin films were synthesized by two different methods: deep ultraviolet (DUV) photolithography and electrophoretic deposition (EPD) of HfO2 nanoparticles. The morphology, composition and crystallinity of the HfO2 nanoparticles and thin films were investigated, and the results showed that both DUV photolithography and EPD are suitable methods to prepare controllable and tunable HfO2 nanostructures.

Summary: This study investigated the electrophoretic deposition of coatings consisting primarily of cobalt, nickel, and iron oxides on stainless steel surfaces. The Co-Ni-Fe oxides were synthesized through thermal decomposition of metal nitrates with different molar ratios. The findings showed that the deposited coatings were mainly composed of spinel-type oxides with round-shaped particles, and the iron content influenced the electrochemical activity of Co-Ni-Fe oxides.

Summary: In this study, the key factors affecting the uniformity, mass, thickness, and density of compacts made from nanopowders of solid solutions of yttrium and lanthanum oxides using electrophoretic deposition (EPD) were investigated. It was found that by adding acetylacetone to the nanopowder suspension and performing EPD in a vertical direction, compacts with high density can be obtained.

Summary: A new carbon coating was proposed to inhibit secondary electron emission. Graphene oxide (GO) coatings were prepared on oxygen-free copper surface using DC electrophoretic deposition, and reduced graphene oxide (rGO) coatings were obtained by hydrogen thermal reduction. X-ray photoelectron spectroscopy (XPS) analysis showed that the oxygen content of the coating decreased significantly after thermal reduction, while rGO coatings still maintained the sp2 hybrid structure. The inhibitory effect of rGO coatings on secondary electron emission was demonstrated.

Summary: Mn3O4 (hausmannite) nanoparticles were synthesized using the pulsed laser ablation method in a liquid environment and deposited on an aluminum substrate using the direct current electrophoretic deposition technique. The effects of deposition voltage and time on the film characteristics were studied using various diagnostic methods. The formation of stable manganese oxide nanoparticles with the chemical formula Mn3O4 was confirmed by X-ray diffraction, and the morphology of the films changed from spherical nanoparticles to nanosheets with increasing deposition voltage. The roughness, average particle size, and thickness of the deposited thin films could be controlled by the applied voltage and deposition time, as observed by AFM studies. Additionally, the reflectance patterns of the samples depended on the material of the thin films and substrates, as well as the size of particles in the film structure, as indicated by UV-Vis-NIR spectroscopy results.

Summary: In this study, graphene oxide was coated onto titanium using electrophoretic deposition to enhance its bioactivity. The graphene oxide-coated titanium improved cell adhesion and proliferation of astrocytes and upregulated the expression of anti-inflammatory cytokines and neuroprotective factors. These findings suggest that the graphene oxide-coated titanium has the potential to induce neuroprotective effects by regulating cell activity.

Summary: Micromagnetic simulations are used to investigate various strategies for tunnel magnetoresistance detection of Neel and Bloch skyrmions. Different skyrmion types passing beneath different magnetized structures show distinct features in the tunnel magnetoresistance as a function of time, which can be used to detect the core direction and chirality.

Summary: The angle dependence of field-induced switching in magnetic tunnel junctions with in-plane magnetization and a pinned synthetic antiferromagnet reference layer was investigated. The results showed that the elliptical nanopillars with dimensions of 60 x 90 nm² exhibited sharp single switches when the field was applied along the major axis, but even with small deviations, reversal occurred through an intermediate state. A model incorporating the external applied field, shape anisotropy, and fringe field of the synthetic antiferromagnet was used to interpret the results and extract the magnetization direction at various points in the magnetoresistance loop. The implications for faster spintronic probabilistic computing devices were discussed.
