Sandblasting, acid etching, and laser surface treatments have known limitations in controlling surface roughness. This study addresses these gaps by investigating the surface texture generated on AISI 316L stainless steel using a Pulsating Water Jet (PWJ) technology. The research evaluates the effect of droplet density distribution by utilizing a traverse speed of <em>v</em> = 4–12 mm/s on surface topography, using linear and areal roughness metrics in accordance with ISO standards, alongside high-resolution SEM imaging of surface morphology. The findings demonstrate a distinct exponential decreasing trend in the roughness parameters, such as <em>Ra</em> = 28.29–1.74 μm; <em>Rz</em> = 214.23–11.11 μm; <em>Sa</em>_<em>P</em> = 26.40–1.91 μm; <em>Sz</em>_<em>P</em> = 307.60–18.96 μm; and <em>Isotropy</em> = 83.85–94.22 %, corresponding to an increase in traverse speed <em>v</em> = 4–12 mm/s. The lower speeds induce crater-rich, valley-dominated surfaces, while the higher speeds produce uniform, isotropic textures of a roughened surface. Wettability results on the generated surfaces showed a hydrophobic surface (&gt;90°) at lower traverse speeds (v = 4 &amp; 6 mm/s), which shifted to hydrophilic at higher traverse speeds (v = 8–12 mm/s). The findings demonstrate the viability of PWJ as a controllable surface treatment method for engineering applications and provide valuable insights into optimizing process–structure relationships through control of traverse speed.</div></div>","PeriodicalId":21085,"journal":{"name":"Results in Surfaces and Interfaces","volume":"22 ","pages":"Article 100688"},"PeriodicalIF":0.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145748532","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The photocatalytic performance of SBA-15-MB was evaluated for methyl orange (MO) degradation under visible LED light irradiation. Optimization studies were conducted to investigate the effects of catalyst dosage, initial MO concentration, and solution pH. The experimental results demonstrate that SBA-15-MB exhibits significantly higher photocatalytic activity than bare SBA-15 under visible light. Under optimal conditions (50 ppm MO, pH 5.5, and 30 W LED lamp), a degradation efficiency of 87 % was achieved within 180 min. The degradation kinetics followed a pseudo-first-order model with a reaction rate constant of 0.012 min⁻¹. Moreover, SBA-15-MB showed good photocatalytic performance toward the degradation of various pollutants, including dyes and antibiotics. The enhanced photocatalytic activity is attributed to the visible light excitation of methylene blue, followed by electron transfer from methylene blue to SBA-15 and radical generation at the catalyst surface.

Recent studies have revealed that, in addition to humidity, light exposure during the annealing process significantly influences phase formation. In this work, we present a comparative study on the effect of annealing temperature using two different approaches: (i) dark annealing (DA) and (ii) vacuum-assisted dark annealing (VADA).

The improved crystallinity and suppression of the δ-phase are attributed to controlled humidity and elimination of light exposure during annealing.

Shrimp shells are a valuable source of chitosan (CS), and chitosan is considered an excellent biomaterial for membranes. In this study, chitosan (CS) was successfully extracted from shrimp shells through deacetylation and used to modify ceramic membranes via surface coating, followed by crosslinking with trimesoyl chloride (TMC) to enhance surface stability. The resulting membrane was highly uniform and hydrophilic, with a water contact angle of 15°. In addition, the underwater oil contact angle reached 157.6°, indicating excellent oil-repelling behavior. The separation performance was evaluated for various oil-in-water emulsions. The CS coating has substantially improved the membrane's performance, increasing from 69.4 % to 99.8 % with an exceptionally high permeability of 315.28 L m² h¹. In addition, the coated membrane was found to have excellent fouling recovery, with FFR% greater than 99 % for 30 filtration runs, without compromising separation performance. Shrimp waste can become a valuable, eco-friendly bio-source for designing chitosan membranes, which can be effectively used for the separation of oil-in-water emulsions with high permeability and separation efficiency. Therefore, the chitosan membrane showed a promising filtration performance, indicating that it could be not only an eco-friendly solution but also a cost-effective and sustainable method for oil-in-water separation.</div></div>","PeriodicalId":21085,"journal":{"name":"Results in Surfaces and Interfaces","volume":"21 ","pages":"Article 100668"},"PeriodicalIF":0.0,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145474267","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
