Summary: This research found that the height of H13 hot-work tool steel samples is significantly affected by the scanning speed during additive manufacturing, and adding a draft angle can reduce side surface roughness. Decreasing scan speed increases surface roughness, while using a finer layer thickness results in overbuilding and a coarser layer thickness results in underbuilding. There is no clear trend in surface roughness when layer thickness is changed.

Summary: The study investigated the surface micro morphology of different types of aggregates and found that the surface micro-roughness and fractal dimensions varied predictably with the formation conditions of aggregates. In addition, the immersion in limewater and physical abrasion had different effects on the SMM of aggregates.

Summary: This paper proposes multiscale characterization methods for additive manufactured surfaces using 3D topographic data at different resolutions. The methods involve point pattern analysis, roughness characterization, and feature-based characterization. The results demonstrate the different contributions of weld track features and particle features to surface roughness at different scales.

Summary: The study evaluated the chemical and morphological changes of femtosecond laser-irradiated enamel using Raman spectroscopy, CLSM, and SEM. Results showed a significant decrease in carbonate content and carbonate/phosphate ratio in enamel after laser irradiation, without altering its structure and morphology.

Summary: The objective of this study was to evaluate the influence of ultrasonic pulsed water jet (UPWJ) peening on Ti6Al-4 V material. The research found that UPWJ peening had a minimal effect on surface roughness but could induce compressive stress under specific conditions. This suggests that the UPWJ method has significant potential for applications in aerospace and automotive engineering.

Summary: The surface properties of building materials play a crucial role in their corrosion due to interaction with water. Water adheres to a surface and damages it, with the extent of damage depending on the material's nature, surface roughness, and porosity. This study focuses on the impact of marble surface roughness on the effectiveness of waterproofing coatings, providing a qualitative and quantitative model for selecting the most suitable coating for corrosion protection.

Summary: Edible oleogels were developed using two different oleogelators in virgin coconut and mustard oils. The study showed that an increase in oleogelator concentration improved the stability and smoke point of the oleogels, while the type of oil had a major effect on the crystal structure of the gels.

Summary: This study examined the impact of mechanical stress on the pellicle of grass roots. Results showed that while mechanical stress caused microdamage in the epidermal layers, the pellicle played a protective role in preventing damage to the protodermal cells, thereby safeguarding the root apical meristem from negative effects.

Summary: This work successfully achieved bypassing hepatic metabolism, controlled release, and enhanced brain distribution of agomelatine by loading it into nanostructured lipid carriers (NLC) and administering via transdermal route. The optimized AG-NLC showed improved solubility and skin permeation, suggesting the NLC-gel system may offer a promising strategy for enhancing brain delivery of agomelatine.
