The review focuses on various membrane technologies employed in oil–water separation, including microfiltration, ultrafiltration, and nanofiltration, highlighting their effectiveness and operational mechanisms. It discusses key challenges encountered by these technologies, such as membrane fouling, high operational costs, and limitations in large-scale applications, which hinder their broader adoption. The paper further examines the characteristics of oil–water membranes, including hydrophilicity, oleophobicity, pore size, and surface roughness, which are crucial in determining separation efficiency. Commonly used materials for developing oil–water filtration membranes are also explored, encompassing polymeric, ceramic, and hybrid materials, with a focus on innovations that enhance performance and sustainability. Additionally, the evaluation of membrane performance is addressed through metrics such as flux, rejection rate, and fouling resistance, offering insights into their suitability for various applications. The review also investigates the parameters varied during oil–water filtration, such as pressure and temperature, and their impact on membrane efficiency and durability. This paper is aimed at providing a roadmap for future research and development in oil–water membrane technology, emphasizing the need for durable, fouling-resistant membrane designs and the exploration of cost-effective materials (such as quartz-based media) to meet global water treatment demands.","PeriodicalId":100886,"journal":{"name":"Material Design & Processing Communications","volume":"2025 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/mdp2/1885168","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145273018","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Approximately 40–60 HRC hardened hot working tool steel is used for the majority of the mould and die materials. Because of the tremendous strength of these materials, the conventional machining processes were limited in their capacity to machine them. When using conventional machining, it will encounter issues such as high tool wear rates and a poor machined surface finish. To address these issues, this research presented a hybrid machining method that incorporates ultrasonic vibration in an axial orientation into the conventional system tooling, referred to as ultrasonic vibration-assisted milling (UVAM), to solve the issues mentioned above. This research was undertaken to understand the effect of axial UVAM parameters on AISI H19 hardened hot working tool steel surface finish. To verify the efficiency of the suggested approach in improving the level of hardened AISI H19 tool steel machined surface roughness, we compared conventional milling (CM) to UVAM for various parameters, including milling spindle revolving speed, rate of feed and cutting depth. Axial UVAM dramatically reduced the machined surface roughness, with up to a 36.7% decrease in the value of Ra compared to the CM approach under the same cutting circumstances, according to the results of the milling tests. The surface prepared by UVAM was homogeneous and had proportionate peak-to-peak magnitude, which enhanced the surface quality, according to the macroscopic examination of the machined surface. Ra values have been strongly affected by the interlinkage between the cutting variables investigated. Continual hammering between the workpiece and cutter teeth greatly influences surface roughness, which is greatly influenced by frequency vibration. When ultrasonic vibration is applied, the level of surface roughness drops dramatically.","PeriodicalId":100886,"journal":{"name":"Material Design & Processing Communications","volume":"2025 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/mdp2/6800758","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145224183","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study focuses on designing and fabricating three WxTixMoNbTaV RHEAs to achieve an optimal balance between strength and ductility at room temperature. The selection strategy was based on leveraging the high strength of tungsten (W) and the excellent ductility of titanium (Ti) to develop an alloy with superior mechanical performance. Three distinct compositions (x1 = [1, 0], x2 = [0, 1] and x3 = [0.5, 0.5]) were synthesised under identical conditions using mechanical alloying (MA), followed by spark plasma sintering (SPS). In our previous study, we conducted an in-depth characterisation of phase transformations during MA and the microstructural evolution after SPS. As a continuation of that research, this study explores the mechanical behaviour of these alloys, revealing exceptional properties. The results demonstrated that the combination of Ti and W is the most effective approach for developing RHEAs with an optimal strength–ductility balance, along with significantly high hardness values, achieving an impressive strength of 1300 MPa and ductility exceeding 20% at room temperature, underscoring their potential for advanced structural applications. These results locate WxTixMoNbTaV alloys as strong candidates for applications in extreme refractory environments and present a promising alternative to conventional nickel-based superalloys for applications in turbines and nuclear reactor walls.","PeriodicalId":100886,"journal":{"name":"Material Design & Processing Communications","volume":"2025 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/mdp2/2598334","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145101727","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The impact of different weight percentages of EVOH blended with PAN on fiber diameters was studied. Fiber diameters drastically decreased with higher EVOH content in the blend, and a slight reduction was observed following isopropyl alcohol (IPA) treatment. The initial diameters of PAN-incorporated EVOH (POH) nanofibers were between 880 and 47 nm, which were reduced to 719 and 41 nm after IPA treatment. The smallest diameter of 102 nm was achieved by POH nanofibers with 75% EVOH after IPA treatment. Furthermore, the thermal properties demonstrate a synergistic effect with the melting temperature increasing from 290°C for pure PAN to 301°C for POH nanofiber with 75% EVOH.

This study explores using rice husk (RH) and white clay (WC) particulates to develop zinc-based composite coatings on A36 steel. Four cathode specimens (80 × 40 × 2 mm) of A36 steel and two zinc anodes (50 × 30 × 2 mm) were prepared. The steel specimens were coated with Zn-10RHWC(t25), Zn-10RHWC(t30), Zn-15RHWC(t25), and Zn-15RHWC(t30), denoted as S1, S2, S3, and S4, respectively. The concentrations used were 10/15 g/L, with deposition times of 25/30 min at a constant cell voltage of 0.5 V. Corrosion rates (CRs) in 3.5 wt.% NaCl were investigated according to ASTM and NACE standards. The coated samples’ hardness, tensile strength (TS), and wear rate (WR) properties were also examined. Scanning electron microscopy (SEM) and X-ray diffraction (XRD) were employed to study the morphology and crystallization of the coatings. The coated specimens exhibited significantly lower CR than the uncoated steel (CR = 8.45 ± 0.58 mm/year). CR values for S1 to S4 were 5.74 ± 0.41, 2.18 ± 0.42, 3.09 ± 0.38, and 5.92 ± 0.45 mm/year, respectively. All coated specimens showed substantial improvements in TS over the uncoated specimen (4.81%, 2.83%, and 4.29% for upper, middle, and lower sections, respectively). Regarding deformation modulus, the Zn-15RHWC(t25) samples exhibited improvements of about 1.31% and 1.38% in the upper and middle sections, respectively, while the lower section experienced a decrease of 2.03%.

It consists of honeycomb and auxetic cells with a tuned material ratio along the femur stem. In the design of the metaimplant, we focused on creating the desired lateral expansion, which makes it a good candidate as the personalized femur implant, decreasing the chance of bone–implant interface failure. For this aim, analytical and computational homogenization methods are used to evaluate a hybrid metamaterial under off-axial compression loading. We show that the lateral expansions of the metamaterial are widely tunable by tailoring Young’s modulus, Poisson’s ratio, and the material ratio of the constituent materials. The hybrid metamaterial outperformed all-auxetic and all-honeycomb designs in terms of bilateral expansion, and the one with maximum lateral expansion was selected for implementation in the design of the metaimplants. The resulting metaimplants show compression on either side of the implant and give smoother stress distribution and lower stress concentration at the contact region of the implants with the femur bone surfaces in comparison to the solid and porous femur implants.","PeriodicalId":100886,"journal":{"name":"Material Design & Processing Communications","volume":"2025 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/mdp2/1863444","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143689107","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

New laboratory methods were developed and applied for this purpose, some of which were based on already established methods. In order to evaluate the influence of temperature on the paving behavior of the asphalt paver, the flow behavior and precompaction resistance were investigated for three selected asphalt mixes (AC 11 DS, SMA 11 DS, AC 16 BS). The temperature was varied in three steps (130°C, 160°C, and 190°C). An extensive literature review of possible laboratory tests was conducted, which concluded that static compaction and the funnel fall test are suitable for investigating the corresponding properties of the asphalt mixes. The results showed that the bulk density of a loose fill asphalt mix is significantly dependent on temperature. Higher temperatures result in higher poured density due to the thermoviscosity of the bitumen, specifically, the viscous τvisc and cohesive τc resistance components. Considering the performed laboratory tests, this phenomenon results in the loose fill of all tested asphalt mixes having a lower precompaction resistance at lower temperatures. In addition, the influence of temperature on the flow behavior and thus the internal friction of the asphalt mixes was demonstrated. Higher test temperatures resulted in a substantial reduction in flow time up to 225% and thus significantly improved flow behavior.","PeriodicalId":100886,"journal":{"name":"Material Design & Processing Communications","volume":"2025 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-02-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/mdp2/9948693","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143466298","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
