The carefully designed ZnO/MnO₂ heterostructure significantly enhances ammonia gas sensing performance at room temperature (RT). By integrating heterojunction formation with structural optimization, this approach facilitates faster charge carrier transport and increases the surface area compared to pure ZnO. The incorporation of nanosheet- and nanotube-structured ZnO/MnO₂ heterojunctions leads to a substantial reduction in response/recovery time, which decrease to 6 s and 3 s, accordingly. Furthermore, first-principles calculations are employed to elucidate the potential sensing mechanism by analyzing the electronic density of states, electrostatic potential, charge transfer, population analysis, and adsorption energy between the sensing materials and ammonia molecules.","PeriodicalId":247,"journal":{"name":"Applied Surface Science","volume":"8 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2025-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143877954","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, molecular dynamics simulations were employed to investigate the shear behavior of undrained montmorillonite (MMT) nanopores with varying surface charges and interlayer cations (Na⁺, K⁺, Ca²⁺), subjected to different normal loads and sliding velocities. Consistent with previous findings, our results confirm that shear stress increases with normal load. However, the normal load-shear stress curves reveal two distinct linear regions, indicating segmented friction behavior. Remarkably, the friction coefficient declines sharply beyond a critical pressure point, ranging from 5 to 7.5 GPa, while cohesion follows an inverse trend. The elevated friction coefficient at lower pressures is attributed to the enhanced formation of hydrogen bonds and concomitant changes in density distribution. Furthermore, shear strength was observed to increase with sliding velocities, normal loads, and surface charges, with Na-MMT exhibiting superior shear strength compared to K-MMT and Ca-MMT. Interestingly, the friction coefficient shows a slight decrease with increasing surface charge, while ion type exerts a minimal effect. In contrast, cohesion is predominantly influenced by surface charge and remains largely unaffected by ion type, except under extreme pressures and velocities.","PeriodicalId":247,"journal":{"name":"Applied Surface Science","volume":"33 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2025-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143877958","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the impact of unsaturated AO molecules in PAO oil on the a-C/PAO system under variable loads complicating experimental characterization and understanding of friction mechanisms. Herein, reactive molecular dynamics simulations were employed to systematically examine the influence of AO molecules on the friction behavior of a-C/PAO composite systems under variable load conditions. Results reveal distinct pressure-dependent mechanisms governing the tribological behavior, highlighting the interplay between hydrodynamic lubrication and interfacial passivation. At low contact pressure, friction behavior is primarily governed by hydrodynamic lubrication, where an increase in AO chain length reduces lubricant mobility. Upon increasing contact pressure to 50 GPa, the friction interface transitions to a regime dominated by the competitive interplay between hydrocarbon passivation and C–C bond formation, but the degree of interfacial passivation induced by AO molecules results in variations in friction performance. As pressure further reverts to 5 from 50 GPa, the fracture of long-chain AO molecules into shorter fragments weakens the difference in interfacial structures between systems. These results deepen the understanding of friction mechanisms involving AO molecules in a-C/PAO systems and provide theoretical guidance for designing high-performance lubrication systems.","PeriodicalId":247,"journal":{"name":"Applied Surface Science","volume":"31 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2025-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143877889","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

X-ray photoelectron spectroscopy analysis of fresh and used catalysts revealed the presence of Pt²⁺and Pt⁴⁺ surface species, even under these challenging reaction conditions. A mechanism is proposed to highlight the synergistic roles of Pt⁴⁺ species for oxygen adsorption and the Pt²⁺/ZrO₂ interface for methane adsorption, reducing the competition between the reacting molecules. Despite an increase in apparent activation energy in the presence of SO₂, NO, or H₂O, the catalyst retains its high activity. The high methane oxidation activity of the catalyst is attributed to the higher velocity of methane molecules, resulting in more frequent and successful collisions at Pt²⁺/ZrO₂ interface compared to other species in engine exhaust. The enhanced stability of the Pt²⁺ surface species is further explained by the energy-level alignment at the Pt²⁺/ZrO₂ interface, which is driven by the interfacial work function values of Pt²⁺ surface species and n-type semiconductor ZrO₂. The results highlight the potential of Pt/ZrO₂ catalyst for efficient and stable methane oxidation in real-world exhaust environments of natural gas engines.","PeriodicalId":247,"journal":{"name":"Applied Surface Science","volume":"41 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2025-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143877957","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, a new collector, cetylpyridinium bromide (CPB), was exploited for the flotation separation of quartz and gypsum. Micro-flotation experiments were carried out to investigate the flotation performance of quartz and gypsum treated with CPB. The collection mechanism of CPB on quartz was examined through Zeta potential, contact angle, Fourier Transform Infrared Spectrometer (FTIR) and X-ray Photoelectron Spectroscopy (XPS) analysis. The flotation results showed that CPB exhibited strong collecting ability and selectivity for quartz from gypsum across a wide pH range of 1.8 to 9.5. Further analysis suggested that the interaction mechanism between CPB and quartz involved hydrogen bond and electrostatic attraction. Through these two interactions, CPB was adsorbed onto the surface of quartz, enhancing the hydrophobicity and floatability of quartz, thus enabling the selective separation of gypsum and quartz. Overall, this research provides a valuable insight for phosphorus chemical industry to achieve the purification of PG.","PeriodicalId":247,"journal":{"name":"Applied Surface Science","volume":"8 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2025-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143876354","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Additionally, as potential pathways for external corrosive ions, cold joints experience interface performance degradation in adverse environments, thereby compromising the durability of the structure. This study utilized molecular dynamics simulations to analyze the shear behavior of two models of concrete joints: the CSH-a-to-CSH-b (CC) interface and the CSH-a-to-SiO₂ (CS) interface, based on calcium silicate hydrate (CSH) and silicon dioxide (SiO₂) as substrates. The study foundthat the penetration ranges of water into the CC and CS interfaces were 17Å and 10.5Å, respectively. When exposed to a saline-alkaline environment, the penetration range of Na₂SO₄ solution increased by 26.5 % and 185.7 % compared to the humid environment for the CC and CS interfaces, respectively. Furthermore, corrosive environments influence ion interactions at the interfaces, leading substrate ions to react preferentially with ions in the corrosive solution, thereby weakening the bonding performance of the interface. The effect of environmental conditions on the shear performance of joints is ranked as follows: saline-alkaline > humid > dry. Under dry conditions, the maximum shear stress of the CC and CS interfaces reached 0.93 GPa and 0.88 GPa, respectively. In humid and saline-alkaline environments, the maximum shear stress of the CC interface decreased by 38.7 % and 68.8 %, while that of the CS interface decreased by 31.8 % and 62.5 %. Additionally, shear failure at the interfaces consistently occurred in regions where bond energy was unstable. This study provides atomic-scale insights into the degradation of concrete cold joints, guiding material design and interface optimization in engineering practice.","PeriodicalId":247,"journal":{"name":"Applied Surface Science","volume":"49 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2025-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143872349","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
