... Aluminium alloys, and particularly aluminium-magnesium alloys (5000 series), are used in the naval, aeronautical, automotive and food industries and they are of great interest due to their low weight, excellent resistance to corrosion, very good thermal and electrical conductivity, good mechanical properties, and high formability. The improvement of the repellency capacity on the surface of parts and elements made with this type of alloy is especially interesting for applications that require self-cleaning [1], anti-icing [2], anti-bacterial [3], anti-corrosive [4], non-stick or in devices for micro-fluidics [5] even optical performance properties [6]. ...
In industrial sectors such as automotive, aeronautics or medical, among others, anticorrosive, antibacterial, self-cleaning, and anti-sticking surfaces are demanded. Thus, the production of these surfaces by scalable processes is currently a subject of intense research but the processes are often complex, slow and use expensive and harmful chemical reagents. In this work, the micro-milling technique with ball nose tools has been proposed as a scalable and environmentally friendly way to improve water repellency on surfaces processed in a 5000 series aluminium and then treated with a hydrophobic coating. Thus, a novel arch-pyramidal protrusion-based surface texture generated by milling has been optimized by means of an experimental set up according to Taguchi's method, evaluating the influence of the process variables on surface hysteresis and hydrophobic capacity of the processed surfaces by means of static, sliding, advancement and receding angle measurements. Classical wettability models have made it possible to define hydrophobic specimens and the appropriate relationships between the water droplet size (d) and the radial milling step (p) have been identified to obtain the better hydrophobic behaviour. So, textures with lower values of crest height (h) and lower roughness factor (r) have shown better hydropho-bicity for bigger water droplets of 50-100 μl and when the ratio d/p is higher. After undergoing over 60 cycles of a peel wear test standardized according to ASTM D 3359-09, the micromilled hydrophobic surfaces exhibit sustained hydrophobic properties, with sliding angles slightly increasing but stabilizing around 11 • , indicative of preserved hydrophobicity.

Permanent magnets generate magnetic fields that can be sustained when a reverse field is supplied. These permanent magnets are effective in a wide range of applications. However, strategic rare-earth element demand has increased interest in replacing them with huge energy product (BH)max. Exchange-coupled hard/soft ferrite nanocomposites have the potential to replace a portion of extravagant rare earth element-based magnets. In the present, we have reported the facile auto-combustion synthesis of exchange coupled Ba0.5Sr0.5Fe10Al2O19 and Ni0.1Co0.9Fe2O4 nanocomposites by increasing the content of soft ferrite over the hard from x= 0.1 to 0.4 wt.%. The XRD combined with Rietveld analysis reflected the presence of hexaferrite and spinel ferrite without the existence of secondary phases. The absorption bands from the FTIR analysis proved that the presence of M-O bonds in tetrahedral site and octahedral sites. Rod and Non-spherical images from TEM represent the hexaferrite and spinel ferrite. Smooth M-H curve and single peak of SFD curve proves that the material has undergone a good exchange coupling. The nano powders displayed an increase in saturation magnetization and decrease in coercivity with the increases in the spinel content. The prepared nano composites were showing higher energy product. And the composite with the ratio x=0.2 displayed a higher value of (BH)max of 13.16 kJ/m3.

Aluminum thin films were deposited on a 3D prototype employing the direct current magnetron sputtering technique to fabricate a lightweight 3D first surface mirror. Before the aluminizing, the surface of the prototypes was evaluated with interferometry and atomic force microscope (AFM). The thin films were characterized using profilometry, UV-Vis spectroscopy, x-ray diffraction, AFM, x-ray photoelectron spectroscopy (XPS), and scanning electron microscopy. High adherence and homogeneous deposition of the aluminum’s thin films were achieved. In addition, the purity of the material was confirmed by XPS analysis.

Slippery liquid-infused porous surfaces (SLIPS) have emerged as a unique approach to creating surfaces that can resist fouling when placed in contact with aqueous media, organic fluids, or biological organisms. These surfaces are composed of essentially two components: a liquid lubricant that is locked within the protrusions of a textured solid due to capillarity. Drops, immiscible to the lubricant, exhibit high mobility and very-low-contact-angle hysteresis when placed on such surfaces. Moreover, these surfaces are shown to resist adhesion to a wide range of fluids, can withstand high pressure, and are able to self-clean. Due to these remarkable properties, SLIPS are considered a promising candidate for applications such as designing anti-fouling and anti-corrosion surfaces, drag reduction, and fluid manipulation. These collective properties, however, are only available as long as the lubricant remains infused within the surface protrusions. A number of mechanisms can drive the depletion of the lubricant from the interior of the texture, leading to the loss of functionality of SLIPS. Lubricant depletion is one challenge that is hindering the real-world application of these surfaces. This review mainly focuses on the studies conducted in the context of enhancing the lubricant retention abilities of SLIPS. In addition, a concise introduction of wetting transitions on structured as well as liquid-infused surfaces is given. We also discuss, briefly, the mechanisms that are responsible for lubricant depletion.

... The anti-corrosion properties of superhydrophobic surfaces arise from their ability to prevent the adhesion of water droplets to the surface, which can reduce the contact between the metal and the electrolyte, thus reducing the corrosion rate [4]. Additionally, the surface roughness of superhydrophobic surfaces can help trap air pockets between the surface and the water droplets, further reducing the surface area in contact with the electrolyte [3]. ...
This paper aims to establish a quantitative relationship between wettability and surface
morphology. The wettability of surfaces is highly dependent on surface morphology,
and this relationship will be explored using either conventional roughness parameters
or power spectral density (PSD) derived parameters. To investigate the effect of
surface morphology on wettability, various Ni-Zn coatings with different hierarchical
surface morphologies were electrodeposited on copper substrates. The coatings
exhibited hydrophobic behavior with apparent contact angles ranging from 105° to
155°, depending on the shape, size, and arrangement of their surface features.
Although conventional roughness parameters like Sq and Spc influenced the wettability
of the coatings, their absolute values could not accurately predict superhydrophobic
behavior. Therefore, the PSD analysis was used as an alternative approach to predict
the wettability behavior of the coatings by distinguishing between nano- and microfeatures. The results revealed that a superhydrophobicity (SH) index could be obtained
from the PSD model to predict superhydrophobic properties. Coatings with an SH
index below 0.32 exhibited a contact angle greater than 150°, regardless of their
deposition parameters. The findings suggest that surface roughness plays a significant
role in controlling the wettability of Ni-Zn coatings, and the SH index is a useful tool for
predicting the superhydrophobic properties of these coatings.

Clay and Clay-based minerals have fascinated attention because of their unique properties and a vast range of applications in innumerable industrial fields. In order to assess the potential applications, six different processed local kaolin-based raw minerals were collected from the Aral Sea region of Uzbekistan, and the total mineralogical properties have been investigated. The result reveals that some significant differences occurred based on the elemental percentage of silica and alumina in all the mineral samples. The presence of corundum, quartz, and kaolinite structural phases of the mineral was determined by XRD studies. At the same time, the FTIR and Raman studies expose the primary peaks which are associated with the functional groups of Al-OH, Al-O, and Si-O in higher-frequency stretching and lower-frequency bending modes. The elemental and chemical compositional (XRF and XPS) analysis demonstrates the presence of major elements (Al, Si, Na, Fe, Ti) in the raw mineral and other metal contaminations (Mg, Ca, S, Cr, Zr). The SEM analysis demonstrates the morphological natureof kaolinite-based raw minerals that can be exploited for industrial purposes.

Inspired by the non-contact nature offered by the superhydrophobic surfaces of living creatures in nature, the superhydrophobic and slippery liquid-infused porous surfaces (SLIPS) have been fabricated to meet the engineering problems including metal corrosion. In this research, we fabricate the hydrophobic, superhydrophobic, hydrophobic lubricant-infused surface (H-SLIPS), and superhydrophobic lubricant infused surface (SH-SLIPS) onto aluminium alloy surfaces and explored their anti-corrosion properties. The hydrophobic and superhydrophobic surfaces are fabricated by hot-water treatment and silicon oil grafting onto the plain and superhydrophilic surface created by hot water treatment of the chemically etched aluminium surface, respectively. The corresponding SLIPS are fabricated by infusion of the silicone oil onto the prepared hydrophobic and superhydrophobic surfaces. Although the superhydrophobic surface exhibits self-cleaning behavior, the SLIPS shows excellent self-healing properties. In addition, the H-SLIPS shows better lubricant layer stability compared to the SH-SLIPS. The corrosion resistive and electrochemical impedance studies illustrate that H-SLIPS surfaces exhibit excellent anti-corrosive properties as compared to other substrates and show long-term performance, even after 30 days. Thus, the study illustrates that H-SLIPS performs better and the infused oil stability is a critical factor for applications like anti-corrosion properties.

Development of multiferroic materials with the capability of compatibility with the current semiconductor technology is of interest for practical applications. Recent experimental discovery of robust ferroelectricity in CMOS-compatible III-nitrides offers an alluring opportunity to construct multiferroic nitrides through chemical-doping engineering. We here reported the coexistence of ferroelectricity and ferromagnetism in Ni-doped Al0.7Sc0.3N thin films. It is found that apart from the promising ferroelectric properties, including a square-like polarization–electric field (P–E) hysteresis loop with a large coercive field (∼3 MV/cm) and high remanent polarizations (∼100 μC/cm2), the films also exhibit room-temperature ferromagnetism, with a saturation magnetization of ∼8 emu/cm3. Additionally, the magneto-dielectric effect has also been experimentally confirmed. Our work provides a reference for subsequent research on nitride multiferroic materials and related applications.

Devising effective methods to reduce drag forces is of great interest as these methods could prevent the wastage of fuel and decrease carbon emission and the global warming rate. Since the invention of Liquid-Infused Surfaces (LISs) in 2011, numerous investigations have been conducted to study their capability in various applications. Due to recirculation or drawing of the penetrated liquid within the surface structure, these surfaces acquire a slippiness property. The conducted investigations showed that these slippery surfaces have great potential for reducing drag forces, whether in a laminar or turbulent flow. In the present work, we first briefly elucidate common drag reduction methods, effective factors, and types of liquid-infused surfaces and their applications. In addition , we address issues such as lubricant evaporation and depletion that threaten the performance of the LISs. Then, we comprehensively focus on the drag reduction ability of these surfaces and state the criteria required to achieve stable drag reduction. Finally, future outlooks and research topics requiring further investigations are discussed.
