“…However, Figure b indicates that fill fractions much lower than 0.55 can maximize the scattering power (Region A), and the remaining question is whether one can experimentally achieve such low fill fractions. Giera et al recently discovered that the fill fraction can be as low as 0.4 when the microspheres undergo high-voltage-driven sedimentation . At this low fill fraction, we predict that light scattering with properly sized microspheres can be stronger than at f ≥ 0.55.…”

We demonstrate that photonic media, when properly randomized to minimize the photon transport mean free path, can be used to coat a black substrate and reduce its temperature by radiative cooling. Even under strong solar radiation, the substrate temperature could reach substantially below that of the ambient air. Our random media that consist of silica microspheres considerably outperform commercially available solar-reflective white paint for daytime cooling. We have achieved the outstanding cooling performance through a systematic study on light scattering, which reveals that the structural parameters of the random media for maximum scattering are significantly different from those of the commercial paint. We have created the random media to maximize optical scattering in the solar spectrum and to enhance thermal emission in the atmospheric transparency window. In contrast to previous studies, our random media do not require expensive processing steps or materials, such as silver, and can be applied to almost any surface in a paint format. The facile and scalable processing steps for our random media point to the possibility that low-cost coatings can be used for efficient radiative cooling.

“…From the point of view of dispersion, the mechanism of stabilization (electrostatic/electrosteric) should promote the individual movement of dispersed nanoentities. However, it is necessary to consider that the yield rate prevail over other parameters, and the solid content, the electrophoretic mobility (zeta potential) and the conductivity should be adjusted to avoid the massive arrival of particles to the electrode, and also the premature agglomeration of nanoplatelets that can disturbs the contribution of the osmotic flow of the solvent to the nanoplatelets ordering, predicted by models [16,17,18]. Those premises should be considering in the fabrication by EPD of electrodes and structures based on nanoplatelets stacking.…”

The electrochemical behaviour of ceramic semiconductors not only depends on the characteristics of the electroactive material but also on the processing method, the nanoparticles arrangement and the consolidation degree of the formed microstructure. In this sense, the use of nanoparticles with plane morphologies (disc, platelets, etc.) results interesting due to the formation of conduction pathways produced as a consequence of their laminar structures. Electrophoretic Deposition (EPD) is a shaping methodology which allows achieving high degrees in nanoplatelets packing by controlling their alignment during the coating process specifically over 3D substrates. In this work, we have studied the effect of a moderate nanoplatelets 2 agglomeration, by tuning their surfaces with a polyelectrolyte multilayer following a Layer-by-Layer (LbL) methodology and fixing the electric conditions of the EPD process. Overcoming the destructive effects of the full agglomeration of nanoplatelets, NiO films with a stable and extremely open macroporous structure were processed to coat Ni foams, improving the capacitive performance of pseudocapacitors leading to values of specific capacitances of 650 F/g. Results collected in this work also evidence that an efficient ordering and orientation of nanoplatelets in EPD mainly depends on tuning the suspension parameters (solid contents, conductivity, electrophoretic mobility, etc.) to avoid the massive flux and interactions among interparticles and electrohydrodynamic forces, as well as the interference of collateral electrode phenomena.

“…The deposition yield can be correlated with various deposition parameters, regardless of the detailed mechanism. Hamaker's law can be used to develop useful mathematical expressions for EPD kinetics [73]. The thickness of which is determined by the EPD parameters, and the morphology of which depends on the deposited substrates [74].…”

Metallic biomaterials such as 316L stainless steel (SS316L) are widely used as an implant to replace the function of damaged bone, especially in hip or knee applications. However, many of them fail during a short period or have complications. The biocompatibility issues are the main factor that caused this failure. Thus, coating the SS316L with bioactive and biocompatible material is one of the promising techniques to enhance the biocompatibility and lifetime of the implant. This paper provides an overview of the SS316L foam coated hydroxyapatite (HA). Various methods of HA coating such as sol-gel, dip coating, electrophoretic deposition, plasma spraying, and pulse laser deposition applied on SS316L foam and their coating characteristics were investigated based on recent literature. SS316L foam coated HA using different coating methods were compiled and their basic properties were reported. Therefore, this paper will benefit future works on SS316L foam coated HA in a biomedical application.
