Summary: Superhydrophobic coatings with unique properties such as self-cleaning and staying dry have recently emerged in industrial and consumer markets. The stochastic nature of coating components can affect the uniformity of water repellency, and traditional contact angle goniometry may not provide accurate quantification of wetting properties. The study demonstrates that highly sensitive force-based methods can offer advantages in quantifying microscale heterogeneity in superhydrophobic coatings.

Summary: Interactions between gas bubbles and solid particles are crucial in industrial processes, and the study aimed to investigate the influence of surface hydrophobicity and zeta potential on the formation of three-phase contact between a single air bubble and planar glass surfaces. The results show that increasing surface hydrophobicity enhances the bubble adhesion effectiveness by increasing both the propagation velocity of the three-phase contact perimeter and its size.

Summary: This paper investigates the effects of different contact angles of superhydrophobicity on friction and wear properties. It is found that as the contact angle of the superhydrophobic nickel surface increases, the coefficient of friction gradually increases while the wear volume decreases. The use of a nanosecond pulsed laser to prepare superhydrophobic surfaces provides a method for achieving surfaces with more suitable friction and wear properties.

Summary: Complete defoliation of trees due to periodic LDD (Lymantria dispar dispar) moth outbreaks is a significant stress factor for tree survival. This study examines a defoliation event in Ontario, Canada in 2021 and finds that quaking aspen trees can completely refoliate in the same year with smaller leaves. The regrown leaves exhibit non-wetting behavior with a hierarchical surface structure, providing a high water contact angle.

Summary: A ZnO/ZnCl2 composite with stable 3D structural morphologies and long lasting superhydrophilicity was synthesized on a nanoPAA substrate. The water contact angle of the composite could be maintained at 0 degrees for 7 days and remained low even after 50 days. The superhydrophilicity mechanism was attributed to the properties of the ZnO/ZnCl2 nanofilm, wrinkled nanoflakes, nanogaps, and structural morphologies.

Summary: The influence of nanomorphology of alumina nanowires on superhydrophobicity was studied by measuring advancing and receding contact angles. It was found that increasing the density of pyramidal ANW structures can enhance superhydrophobicity, while nanowire bending decreases the advancing contact angle.

Summary: A simple, scalable, rapid, and eco-friendly method for fabricating superhydrophobic titanium surfaces using rapid breakdown anodization (RBA) was developed. The desired hierarchical surface morphology for superhydrophobicity was achieved by controlling RBA process parameters and low surface energy modification using stearic acid (SA). The anodized samples showed excellent self-cleaning, adhesion, and abrasion resistance properties.

Summary: This article discusses the fabrication of micro/nano hierarchical structured aluminium surfaces with a wide range of wettability and controllable adhesion using a simple and environmentally friendly method. The surfaces show hydrophobicity with high adhesion due to impregnated wetting state, and become superhydrophilic after the formation of aluminium oxide and hydroxide nanoflakes. After fluorination, the surfaces exhibit superhydrophobicity with very low contact angle hysteresis, high chemical and thermal stability, and excellent self-cleaning capability.

Summary: The research investigated how activation of glass surface by air cold plasma influences changes in the surface properties of gluten deposited on such surface. Indirect cold-plasma treatment caused modification of gluten surface, resulting in smoother surfaces with higher apparent surface free energy. This method can improve the applicability of gluten, reduce stickiness, and be used to obtain active packaging and biodegradable films with less food loss.

Summary: The study presents a phosphonate functionalized ordered mesoporous silica as an efficient adsorbent for uranium removal in acidic conditions, achieving a high up-to-date capacity of 345 mg/g at pH = 4. The presence of other polyvalent cation does not affect the efficiency of adsorption, suggesting inner-sphere complex formation as the mechanism. The surface chemistry was found to be the key feature for the selective and stable removal of U(VI) species, based on spectroscopic validations of surface adsorbed U(VI).

Summary: The main objective of this study was to investigate the possibility of using a combination of vegetable proteins and liquid syrups in high-protein bars. The combinations of proteins and syrups had positive effects on the hardness reduction of the bars. Microstructure and contact angle showed a large influence on the features of the manufactured products. The combination of proteins and syrups significantly reduced the sugar content of the product, and certain combinations showed a high potential for use in this type of products.

Summary: This study thoroughly investigated the effect of three popular surface activation methods on the titanium oxide surface to identify the most effective protocol for enhancing hydrophilicity. The results showed that all three methods resulted in an enhanced hydrophilic surface, as evidenced by reduced contact angle values. The chemical and morphological features responsible for the increased hydrophilicity were further examined using atomic force microscopy and X-ray photoelectron spectroscopy.

Summary: Examples of nanostructured fluids (NSFs) used as highly specialized brush-on, wipe-off detergents for the removal of graffiti coatings resistant to removal are water-in-oil nanoemulsions that have been stabilized with nonionic saccharide surfactants. Safe and ecofriendly nanodetergents were produced using high-pressure homogenization (HPH) with ingredients such as D-limonene or 3-methoxy-3-methyl-1-butanol, esterified vegetable oils, and alkyl polyglucosides (APG). The effectiveness of these nanodetergents in removing stubborn graffiti coatings varied, indicating that surface properties of the coatings alone may not determine the removal efficiency.

Summary: The study investigated the gelation process of binary mixes of pumpkin-seed and egg-white proteins. Substituting pumpkin-seed proteins with egg-white proteins improved the rheological properties of the obtained gels. Gels with a higher egg-white protein content were more elastic and resistant to breaking, while a higher concentration of pumpkin-seed protein changed the gel microstructure to a rougher and more particulate one.

Summary: In this study, the quality of limestone and dolomite aggregates was evaluated through methylene blue adsorption experiments. The results showed good repeatability using both the methylene blue stain test and the adsorption experiment. The measured specific surface areas differed between N2 adsorption and methylene blue adsorption, which can be attributed to the presence of quartz and clay minerals in the aggregates.

Summary: The effects of magnetic field treatment on water or solution are still of interest, but there have been relatively few studies on pure surfactant solutions. This study investigated the effects of magnetic field treatment on pure aqueous surfactant solutions, including cationic, anionic, and nonionic surfactants. The results showed that both uniform and gradient magnetic fields can cause changes in surface tension, with the effects being stronger in the gradient field. The specific changes in surface tension depend on the type and concentration of surfactant.
