        <description><![CDATA[High-entropy alloys (HEAs) and medium-entropy alloys (MEAs) have demonstrated many superior properties, including high strength, toughness, and thermal stability. Among MEAs, AlCrFeNi has received considerable attention due to its well-balanced mechanical properties and cost-effectiveness, making it a promising candidate for industrial applications. It is known that rare-earth elements can effectively enhance the oxidation resistance of alloys containing passive elements. In this study, AlCrFeNi MEAs with Y additions (0.5, 1.0, and 1.5 wt.%) were fabricated by arc melting. Microstructures of fabricated samples and their mechanical properties and resistance to air-jet sand erosion were investigated at both room temperature (20°C) and elevated temperature (700°C). For the sake of comparison, a commercial nickel-based Waspaloy superalloy was also evaluated. At both room and elevated temperatures, the AlCrFeNi MEA demonstrated high superiority over the widely used nickel-based superalloy. The Y additions increased the hardness and yield strength of the MEA, leading to improved erosion resistance at room temperature, which was more obvious at elevated temperatures, largely benefiting from the improved resistance to accelerated oxidation at elevated temperatures. The obtained information highlighted the beneficial effects of the minor Y additions in enhancing both the mechanical performance and high-temperature durability of the AlCrFeNi MEA, which would help extend the application of the MEA to higher temperatures.]]></description>

        <description><![CDATA[In this paper, we present results of a study on the influence of different experimental conditions on drug release, for the two anticancer drugs: doxorubicin (DOX) and sorafenib (SO), from mesoporous silica nanoparticles coated with polydopamine (PDA) shell. We tested the drugs release from the carrier into buffers of different pH (4.5; 5.5; 7.5) and with the addition of H2O2 or glutathione (GSH), while stirring the carriers in a flask or shaking them in a thermoblock, keeping the same time intervals, temperature and frequency. The obtained results and performed statistical analysis prove that the way the drug release tests are conducted has a significant influence on the efficiency of release of both drugs from the carrier. Thus, our results are of great importance for characterization of multimodal nanocarriers for biomedical application in terms of drug release and bring new knowledge for their methodological investigation.]]></description>

        <description><![CDATA[Failure in the adhesion between hydroxyapatite and the metallic substrate in commercial biomaterials is one of the significant drawbacks in implantology. The demand for confident analytical methods to characterize these coatings is met through a rigorous research process. Fourier-transform infrared spectroscopy (FTIR) was chosen as the method to characterize hydroxyapatites. A meticulous data analysis from FTIR spectra was conducted, and an FTIR library was constructed from FTIR spectra of different types of hydroxyapatites, considering several chemical environments. The analytical procedure involved the registry of the spectra, localization of the leading absorption bands from the minima of the second derivative spectra, and reconstitution of the original spectra by curve deconvolution. The FTIR library was employed to analyze commercial surgical screws that failed in their use in different implants. Our methodology identified the structural reasons for such failure, caused by the selective removal of non-apatitic environments during adsorption onto the metallic implant. The method identifies the adhesion degree of the apatite coating on the implant before implantation in a biological organism, thereby preventing additional patient interventions and the associated costs.]]></description>

        <description><![CDATA[Dye-sensitized solar cells comprise a fluorine doped tin oxide/titanium dioxide photoanode and a counter electrode of fluorine doped tin oxide covered with a catalytic material arranged in a sandwich configuration. Many processes take place inside a dye-sensitized solar cell. However, two involve the redox couple contained in the electrolyte solution: the dye regeneration and the recombination. While the first is a desired path, the latter impacts the power conversion efficiency of the cells, decreasing the measured values. In this work, iodine-based couples are evaluated using cyclic voltammetric measurements, and their behaviour is compared with two commercial electrolytes widely used in dye-sensitized solar cells, particularly when sensitized with natural dyes. Different experimental conditions, such as cell configurations and electrode materials, were adopted to understand the thermodynamics of the competitive electron transfer processes mentioned above.]]></description>

        <description><![CDATA[The encapsulation of active ingredients is an important process in various industrial sectors including pharmaceutics, foods and cosmetics. For the first time, the capacity of non-conventional anti-Bancroft oil-in-water Pickering emulsions stabilized by partially hydrophobized silica to encapsulate an apolar active is addressed. A dispersed phase volume of paraffin oil of 50% coupled to 0.5 wt.% of silica has been employed to avoid excess of silica in the continuous phase and encapsulate higher amount of ibuprofen (the model drug). Three ibuprofen contents ranging from 100 mg (1.6 mg/mL of paraffin) to 420 mg (6 mg/mL of paraffin) have been tested. The encapsulation efficiency as well as the emulsions properties are investigated by the means of light diffusion, microscopy, rheology, and HPLC coupled to mass balance. The Pickering emulsion is very efficient for the encapsulation of ibuprofen with encapsulation rates of 99% obtained inside droplets of 30 µm for all the 3 ibuprofen concentrations. This encapsulation ability is perfectly maintained, whether during ageing (during 90 days), or when the emulsion is diluted by a factor 100 inside physiological media at basic and acidic pH.]]></description>

        <description><![CDATA[The interdependence of adhesion, friction, and elasticity of elastomers is relevant for various engineering applications. However, its investigation has been limited to smooth glass surfaces. We apply atomic force microscopy (AFM)-based methods to quantify PDMS’s elastic and tribological properties in single asperity contacts (quasi-static and sliding) with a nanometer-scale SiOx asperity under dry conditions. The selected experimental approach allows us to model the contact initiation with PDMS and its degradation. Combining quasi-static and reciprocal sliding experiments, we identify several contributions to adhesion and friction: junction formation, elastic deformation, rupture, and adhesive material transfer. Furthermore, we find correlations between the elastic deformation of PDMS/SiO2 junctions and their adhesion hysteresis on the one hand and the shear strength and the work of adhesion on the other.]]></description>

        <description><![CDATA[The sol–gel process is a simple wet chemical method used to generate nano-crystalline or nano-scaled amorphous ceramic and ceramic–polymer hybrid coatings. Pure ceramic and pure polymer coatings have certain limitations for use over a wide range of applications due to the high-temperature heat treatment requirement for the former and poor mechanical properties of the latter. Hence, ceramic–polymer hybrid coatings are the need of the hour for use in diverse applications on different substrates. Furthermore, bioinspired multifunctional coatings that mimic complex geometrics of the lotus leaf, pitcher plant, etc., are being investigated for their use in corrosion protection, biofilm inhibition, antifouling, etc. Such complex geometries can be generated by a combination of physical and chemical modifications of a surface. In the case of the chemical modification of a surface, instead of a pure ceramic or pure polymer coating, a ceramic–polymer hybrid coating would be the choice, as, a rigid backbone is provided by the ceramic (metal oxide network) moiety and a flexible structure by the polymeric moiety. This review discusses the sol–gel-derived pure ceramic and ceramic–polymer hybrid coatings, their applications, challenges, research gaps as they have been evolving over the years, and two nature-inspired phenomena, namely, superhydrophobicity and self-healing, that have been widely researched for use in various applications.]]></description>

        <description><![CDATA[Electric vehicles (EVs) represent a new paradigm for a sustainable transportation future with the potential to offer unparalleled energy security, environmental cleanliness, and economic prosperity for all humanity. However, rapid development and adaptation of this new transportation approach depend on addressing multiple challenges, including the development of new materials and coatings that can meet the more stringent thermal, electrical, and tribological requirements of EV drivetrains. Specifically, the operating conditions of moving mechanical assemblies (i.e., bearings, gears, among others) in EVs differ radically from those found in conventional internal combustion (IC) engines—thus giving rise to notable reliability issues. In particular, as the function of bearings and gear systems shift from mostly load-carrying (in IC engines) to the torque-transferring mode in EVs, durability concerns of these assemblies due to severe deformation, wear, micro-pitting, fatigue, and scuffing may worsen—as electric motors can generate maximum torque at near zero speeds but maximum efficiency at around 90% speed (this is opposite of conventional IC engines, which generate high torques at high speeds). These conflicting requirements require a different set of lubricant-material combinations to circumvent such problems under high loads and low-speed conditions of EVs. Therefore, new materials, coatings, and lubrication strategies need to be developed and implemented for future EVs to become tribologically viable and reliable. Accordingly, EV drivetrains can potentially benefit from advanced functional coatings that have already significantly improved the functionality of moving components of IC engines. The main objective of this article is to draw attention to some of the tribological issues in EVs and how advanced functional coatings can help resolve these issues due to their unique thermal, electrical, mechanical, and tribological properties, ultimately making EVs more durable and reliable.]]></description>

        <description><![CDATA[High-entropy oxides (HEOs) containing five or more cations have garnered significant attention recently due to their vastly tunable compositional space, along with their remarkable physical and mechanical properties, exceptional thermal stability, and phase reversibility at elevated temperatures. These characteristics position HEOs as promising candidates for structural components and coatings in high-temperature applications. While much of the ongoing research on HEOs centers around understanding processing-structure relationships, there remains a dearth of knowledge concerning their mechanical properties, crucial for their prospective high-temperature applications. Whether in bulk form or as coatings, the efficacy of HEOs hinges on robust mechanical properties across a spectrum of temperatures, to ensure structural integrity, fracture resistance, and resilience to thermal stress. This review offers a succinct synthesis of recent advancements in HEO research, spanning from processing techniques to mechanical behaviors under extreme conditions. Emphasis is placed on three key aspects: (1) Investigating the influence of processing parameters on HEO crystal structures. (2) Analyzing the interplay between crystal structure and mechanical properties, elucidating deformation mechanisms. (3) Examining the mechanical behavior of HEOs under extreme temperatures and pressures. Through this review, we aim to illuminate the effective control of HEOs’ unique structures and mechanical properties, paving the way for their future applications in extreme environments.]]></description>

        <description><![CDATA[Zirconium is an attractive engineering material owing to its commendable temperature, corrosion resistance, and excellent biocompatibility. Despite these merits, its industrial applicability is hindered by elevated wear and friction in tribological settings. Previous research has concentrated on unmatched pair contacts involving zirconium and alumina primarily due to the exceptional hardness. However, there is a noticeable dearth of literature on the matched pair contact condition for zirconium dioxide. Thermal oxidation is a promising and cost-effective method to address the suboptimal tribological performance and enhance the mechanical and electrochemical properties of zirconium. In this study, thermal oxidation is employed to produce a 6-μm-thick oxide layer in an air furnace at 650°C for 6 h. Subsequently, the resulting surface coating was tribologically tested using a pin-on-disc tribometer against two distinct counterface materials, namely, alumina and zirconium dioxide, in a dry and unlubricated environment. The findings reveal that matched contact between the zirconium dioxide tribopair is unfavorable, leading to elevated friction and wear rates. Consequently, this configuration should be avoided in dry contact situations characterized by high contact pressures. However, under lower contact pressures, the wear performance is acceptable. Furthermore, when combined with lubrication, this system may have potential applications in bio-tribological systems.]]></description>

        <description><![CDATA[This work evaluates the influence of plating variables on the morphology, composition homogeneity, and abrasive wear resistance of metal matrix composite coatings. A set of Ni/Cr3C2 coatings were brush plated onto steel coupons modifying two key variables: particle size and brush material. Compositional maps of unprecedented detail have been produced and analysed statistically to enhance understanding of composition distribution. The use of Abbott-Firestone curves to analyse surface morphology enabled the evaluation of valley and peak features. The coating differences highlighted by previous analyses have been compared with their behaviour in abrasive environments, simulated using Taber testing. Moreover, coupling Taber testing with partial compositional maps at different wear stages enabled monitoring of coating wear evolution. This methodology has revealed the importance of particle sedimentation during plating, which increased particle incorporation in the composite coating but also increased composition heterogeneity. The smaller 1.7 μm carbides and abrasive brushes produced coatings with more homogeneous morphologies, higher particle content, and increased resistance against abrasive wear, with a 60% reduction in material loss in comparison to the standard nickel coatings.]]></description>
