Macroscopic surface roughness in metal‐dielectric composite films: Photothermal absorber applications

The surface roughness growth of electrodeposited chromium films was investigated with a particular focus on the impact of water and an organic additive, acetylacetone, on the surface roughness scaling, the surface morphology, and microstructure. Cr-composite films were prepared by new deep eutectic solvent and deposited on Nickel substrate utilizing the electrodeposition technique. Acetylacetone sources enhanced nucleation at the initial deposition stage, and the surface roughness of the films was reduced noticeably. The surface structure was studied by profilometry and 3D optical microscope. The low average roughness values ([Formula: see text]1.5[Formula: see text][Formula: see text]m) are achieved by adding water and acetylacetone, utilizing the novel ionic liquid. The most significant of the outcomes are associated with the role of water and acetylacetone which gives a reduction not only in [Formula: see text] but also in [Formula: see text] and [Formula: see text]. The obtained outcomes are promising for Cr electrodeposition, which are capable of yielding hard chromium coatings with enhanced surface structure.

Osteoblast Adhesion

Multifunctional scaffolds are becoming increasingly important in the field of tissue engineering. In this research, a composite material is developed using polycaprolactone (PCL) and detonation nanodiamond (ND) to take advantage of the unique properties of ND and the biodegradability of PCL polymer. Different ND loading concentrations are investigated, and the physicochemical properties of the composites are characterized. ND-PCL composite films show a higher surface roughness and hydrophilicity than PCL alone, with a slight decrease in tensile strength and a significant increase in degradation. Higher loading of ND also shows a higher osteoblast adhesion than the PCL alone sample. Finally, we show that the ND-PCL composites are successfully extruded to create a 3D scaffold demonstrating their potential as a composite material for tissue regeneration.
