“…The implantation of a biomaterial in the body establishes immediately a solid/liquid interface involving the solid phase and the constituents of the biological fluid. For that, the surface wettability, which refers to the study of how a liquid spreads out on a solid substrate, is one of the most important parameter affecting the biological response to an implanted material …”

In this work, TiO2 layers are synthetized on Ti6Al4V alloy substrate by electrochemical anodizing process in fluoride‐containing alkaline electrolytes and under different applied voltages (10, 20, and 30 V). The scanning electron microscopy (SEM) reveals a nearly regular and vertical alignment of TiO2 nanotubes (≈80–100 nm) for specimen treated at 20 V and an agglomerate of particles with no particular orientations for those specimens treated at 10 and 30 V. The X‐ray diffraction (XRD) indicates the formation of mixed phases of anatase and rutile. Wettability measurements exhibit hydrophilic and superhydrophilic surfaces, according to the anodization parameters. The electrochemical impedance spectroscopy (EIS), performed in a simulated body fluid (Hank's solution), reveals an increase in corrosion resistance for a bias potential of 20 V (262 kΩ) owing to the evolution in TiO2‐layer thickness, and then decreases for higher anodizing potential values due to the chemical dissolution of the obtained layer.

In the past few years, three‐dimensional self‐supporting porous magnetic assemblies (3D‐SPMAs) have emerged as a new research area in materials science because of their combined features of three‐dimensional self‐supporting porous assemblies (3D‐SPAs) and magnetic materials. Due to these attributes, 3D‐SPMAs gain numerous tempting properties such as magnetism‐induced actuating, magnetic shape memory effects, and alternative magnetic field (AMF) induced heat generation, showcasing huge potential in diverse applications stretching over water remediation, actuators, biomedical therapy, etc. Especially, 3D‐SPMAs displayed eminent potential in water remediation for their large processing capacity, remote controllability, and magnetic‐field‐mediated wettability. With the rising interest in 3D‐SPAs, the increasing understanding of magnetic materials, and the flourish of materials preparation technique, an upsurge has appeared in 3D‐SPMAs and thus managing them a class of emerging and promising functional materials. However, currently there are rarely review papers concerning 3D‐SPMAs. In this light, this review aims to express a comprehensive overview of this young field and fuel further innovations for preparation methods and practical applications of 3D‐SPMAs. The focus is placed on the synthetic strategies and applications especially in water remediation. The potential opportunities and challenges are also discussed.

“…for hexadecane this transition occurs at 125 o , which is far removed from the 90 o value applying for water). 348 There is also a need to study how surface coatings modify the thermal conductivity of surfaces. The physics behind DwC nucleation and its dependence on wetting are poorly understood, as the temperature difference involved in the process is often in the range of the instrumentation error.…”

Among numerous challenges to meet the rising global energy demand in a sustainable manner, improving phase change heat transfer has been at the forefront of engineering research for decades. The high heat transfer rates associated with phase change heat transfer are essential to energy and industry applications; but phase change is also inherently associated with poor thermodynamic efficiencies at low heat flux, and violent instabilities at high heat flux. Engineers have tried since the 1930's to fabricate solid surfaces that improve phase change heat transfer. The development of micro and nanotechnologies has made feasible the high-resolution control of surface texture and chemistry over length scales ranging from molecular levels to centimeters. This paper reviews the fabrication techniques available for metallic and siliconbased surfaces, considering sintered and polymeric coatings. The influence of such surfaces in multiphase processes of high practical interest, e.g. boiling, condensation, freezing, and the associated physical phenomena are reviewed. The case is made that while engineers are in principle able to manufacture surfaces with optimum nucleation or thermofluid transport characteristics, more theoretical and experimental efforts are needed to guide the design and cost-effective fabrication of surfaces that not only satisfy the existing technological needs, but also catalyze new discoveries.
