Summary: The study found that different types of varnish and their structural differences affect the glossiness of wood samples. UV varnish has higher gloss values than water-borne varnish, and is more sensitive to heat exposure. The gloss values of samples decrease during artificial aging process, but no layer cracks were observed.

Summary: This study aimed to evaluate the behavior of spiral polishing systems in restorative materials using optical coherence tomography (OCT). The performance of spiral polishers specific to resin and ceramics was evaluated. Surface roughness was measured and images of the polishers were obtained by OCT and stereomicroscopy. OCT was able to evaluate wear areas in spiral polishers.

Summary: This study compared the surface gloss and roughness of three contemporary composites polished using reduced-step polishing systems versus a conventional multiple-step technique. The results showed that the two-step composite polishing systems produced superior gloss compared to the traditional multiple-step system, with a high correlation between surface roughness and gloss. The findings suggest that the reduced-step polishing systems could lead to significant time savings and faster polishing protocols in clinical practice.

Summary: This study investigated the changes in gloss, roughness, and total color change properties of four commonly used natural stones due to the spillage of various food, beverage, and cleaning materials. The effect of these stains on the internal structures of the stones was also analyzed. The results showed that KB sample had the highest gloss loss after descaling, while MW sample had the least. KB sample also had the highest roughness increase after descaling, while MW sample had the least. Cooking oil had the most negative effect on the total color change properties of the stones.

Summary: This study evaluated the effects of a 30% hydrogen peroxide solution containing different content of 45S5 bioactive glass on tooth whitening efficacy and enamel surface properties. The results showed that the solution with bioactive glass increased the pH, which inhibited demineralization of the enamel surface. The content of bioactive glass also affected the gloss of the enamel surface.

Summary: This study investigated the natural weathering behavior of sixteen different wood species under the same conditions for a year, showing that the surfaces of pine, maple, and tulip samples experienced the darkest and greatest color changes, while walnut, A. walnut, and oak samples showed the least color changes. High-density wood species demonstrated more stability against color changes, while there was no significant correlation between density and roughness or gloss property changes.

Summary: This study developed a novel method using the SAICAS instrument to evaluate the mechanical properties of coating layers without special sample preparation. The spreading of latex binder and chemical composition of S/B latex were found to have significant impacts on the final properties of the coating layer, such as peel strength and gloss.

Summary: A novel waterborne polyurethane (WPU) coating with a self-roughed surface was prepared using a general prepolymer emulsion polymerization method. The introduction of a polyfunctional amine-based chain extender formed a rough surface on the WPU film, resulting in a decrease in gloss. The chain extension improved the thermal stability and tensile strength of the film, and this WPU material can serve as an effective alternative for low-gloss coatings without the need for matting agents and special treatment processes.

Summary: This study examines the relationship between measured gloss and the microstructure of printed UV-inks containing aluminum pigments. The impact of dwell time and hot air on gloss and the topography of the pigment layer, as well as the influence of the substrate, were investigated. It was found that a longer dwell time and hot air have a positive effect on the specular gloss of metallic ink printed on Chromolux paper, while on primed Multi Art Gloss paper, they can have a negative impact.

Summary: This in vitro study evaluated the effects of artificial aging on the color, gloss, and surface roughness of 3D-printed veneers. The results showed that artificial aging led to increased color changes, surface roughness, and reduced gloss in all materials. Moreover, the 3D-printed veneers exhibited higher color changes and surface roughness compared to the prefabricated resin composite veneer systems.

Summary: Organic molecules in Pinus sylvestris L. act as a safety net for metal transport, chelation, and sequestration, facilitating adaptation and growth under highly polluted conditions. The content of specific organic molecules was significantly higher in pine trees growing in polluted areas compared to unpolluted areas, indicating their role in metal/metalloid tolerance.

Summary: The study found that heat treatment in an open system significantly decreased the shear strength of Scots pine wood, while the decrease in shear strength was smaller in a closed system. Additionally, using glue increased the shear strength of wood samples, and lower shear strength of modified wood could be attributed to factors such as reduced chemical bonding and substrate strength. Furthermore, the pull-off adhesion decreased with increasing heat treatment temperature, with the highest adhesion observed in samples coated with polyurethane-based varnish.

Summary: The destructive effects of moisture and temperature on cellulosic and nanocellulosic substrates are inevitable. This review paper discusses the need to develop waterproof and flame-resistant cellulose-based substrates to improve the quality of these materials. It summarizes the different types of cellulosic substrates, nanocellulose, and information about water repellents and fireproof coatings, and addresses the potential and necessity of using cellulosic biobased substrates as waterproof and fire inhibitor coatings.

Summary: The study shows that the silane-starch coating can improve the hydrophobic properties and durability of paper. Silanes with short aliphatic carbon chains are easily embedded in the starch structure, while those with longer side chains are primarily localized on the starch surface. The best hydrophobic properties were achieved with a combination of starch and methyltrimethoxysilane.

Summary: This article investigates the effects of crystalline or fibrous nanocellulose on the mechanical properties of paper substrate. The selective reinforcement of paper treated with different nanocellulose samples is observed. Changes in fiber structure and physical properties are evaluated. The study concludes that the decrease in strength properties of paper after applying some nanocellulose compositions is due to the loss of potential disturbances in hydrogen bonds, while significantly increased strength is observed in the case of paper reinforced with nanocellulose functionalized with carboxyl groups.

Summary: The aim of this study was to assess the properties of coatings incorporating nanocellulose for use in surface modification and biodegradable packaging. The nanocellulose coatings were sensitive to water vapor but had a lower tendency to absorb liquid water. Coatings with additional modifying substances acted as a barrier to liquid water penetration. The nanocellulose coatings increased the tensile strength of the samples.

Summary: The sorption properties of paper products are crucial for their use as packaging materials. Hydrophobicity, which refers to reduced affinity of paper surface to liquid water, has a direct impact on the packed goods. However, the hygroscopicity of the material is important during storage. This study analyzed the changes in hygroscopic properties of paper products treated with silane modified starch, and evaluated different sorption isotherm models to quantify the hygroscopic properties.

Summary: The research found that 3-(2-aminoethylamino)propyltrimethoxysilane was more effective in modifying MCC compared to Methyltrimethoxysilane, with pure water being the most effective solvent among the three tested. The type of functional group in alkoxysilanes is crucial for their chemical reactivity with natural polymers.
