The martensitic phase transformation (MPT) is one of the most important factors that enhances the surface roughening of stainless-steel thin metal foils (TMF), such as SUS 304, compared to others without MPT, even in the same plastic strain. However, the conventional roughening model does not take into account the influence of MPT. In this study, the authors proposed a new constitutive model to express the surface roughening by taking the influence of MPT into account. The volume fractions of MPT for TMF of SUS304 in various grain sizes are accounted for quantitatively after the tensile test at room temperature and an elevated temperature, and the effect of MPT on the surface roughening is evaluated in comparison to using TMF of SUS316, in which MPT does not occur during plastic deformation. Then, a constitutive model of the surface roughening based on the experimental results is successfully built.

The aim of the study is to assess the impact of mechanical surface treatments on the shear bond strength (SBS) of orthodontic brackets bonded to three-dimensional (3D) printed and milled CAD/CAM provisional materials. Sixty cylindrical samples were fabricated for each provisional material. Samples were treated with one of the following surface treatments: aluminum oxide airborne particle abrasion, diamond bur rotary instrument roughening, and phosphoric acid etching (control).

In recent years, the advancement of high-frequency communication systems, particularly 5G and future 6G technologies, has increased the need for substrates that minimize signal loss and electromagnetic interference. Glass substrates are highly desirable for these applications due to their low dielectric constant and excellent surface smoothness. However, conventional electroless Cu plating methods struggle to achieve strong adhesion between Cu and the smooth, low-polarity surface of glass, making this an important challenge to address.

The use of metal oxide catalysts to enhance plasma CO reduction has seen significant recent development towards processes to reduce greenhouse gas emissions and produce renewable chemical feedstocks. While plasma reactors are effective at producing the intended chemical transformations, the conditions can result in catalyst degradation. Atomic layer deposition (ALD) can be used to synthesize complex, hierarchically structured metal oxide plasma catalysts that, while active for plasma CO reduction, are potentially vulnerable to degradation due to their high surface area and nanoscopic thickness.

Objective: Evaluating immediate and delayed micro shear bond strength (µSBS) between composite resin and glass ionomer cements using different adhesive systems and mechanical surface treatment.
Materials And Methods: A total of 240 specimens of glass ionomer restorative materials were divided into two groups: Resin Modified Glass Ionomer Cement (RMGIC) namely Riva Light Cure and Conventional Glass Ionomer Cement (CGIC) namely Riva Self Cure. These were subdivided into immediate (24 h) and delayed (3 months) storage and further divided into smooth, medium, and rough surface treatment with either total etch (TE) or self-etch (SE) adhesive strategies.
Surface Roughening Behavior and Mechanism in Aluminum Alloy Under Tensile Deformation.

Surface roughening (SR) has been found to occur in solid solution 2219 aluminum alloy under tensile deformation, which will deteriorate its surface quality. To make a precise study of the surface roughening (SR) behavior and mechanism, the surface morphology of annealed and solid solution 2219 aluminum alloy was compared and crystal plasticity finite element (CPFE) simulation was carried out in this study. Thereinto, representative volume element (RVE) models of polycrystals were established according to the initial grain morphology measured by electron backscatter diffraction (EBSD).
