However, improper control of ink viscosity and flow during the screen-printing process can result in poor print quality and film uniformity. Vacuum filtration methods also have limitations in film transfer and large-scale production. Here, a uniform composite film is constructed on a polymer flexible substrate via room-temperature evaporation. Exploiting differential sedimentation rates in a gravitational field, this process yields a bilayer structure where the active material forming the bottom layer (in contact with the substrate) and MXene forming the top layer. FESEM and XRD analyses verify the formation of a well-defined bilayer heterostructure. Moreover, FESEM images reveal that perforation by the underlying nanowires imparts a porous architecture to the top MXene layer, thereby accelerating ion transport. Benefiting from the unique bilayer heterogeneous structure, the optimized composite film electrodes (MXene-Mo₂C@N/C) exhibit outstanding capacitive performance, achieving an areal capacitance of 70 mF cm⁻² and a volumetric capacitance of 86<!-- --> <!-- -->F<!-- --> <!-- -->cm⁻³, both at 0.1<!-- --> <!-- -->mA<!-- --> <!-- -->cm⁻³.

It has been demonstrated that during non-isothermal crystallization, the crystallization peaks move to higher temperatures as the rate of temperature rise increases. The thermal stability of the α-Fe(Si) phase is found to be better by calculating the nucleation activation energy and growth activation energy.

The results demonstrate that 5% SnO₂/ZnO, prepared with 5% Sn doping, exhibits exceptional selectivity for formaldehyde. Under testing conditions of 170 °C and relative humidity below 60%, the 5% SnO₂/ZnO sensor achieved a selectivity coefficient of 0.87 toward 50 ppm formaldehyde, with a response value of 72.8, response and recovery times of 81/30<!-- --> <!-- -->seconds, a linear regression coefficient of 0.9997, and a minimum detection limit of 0.047 ppm.

The study of material deformation and failure mechanisms can only be conducted through purposeful deformation and destruction of the materials. However, existing material loading test methods struggle to effectively evaluate deformation states involving severe grain deformation and fracture. In this study, a new material loading test method based on shear-based material removal under the quasi-static condition was proposed. The offset loading configuration between the cutting insert and the specimen induces severe compressive and shear deformation within the deformation zones. Moreover, a microscale quasi-static-cutting (MQSC) test rig was developed to obtain the grain-scale images and microstructure information in the shear-based material removal test (SMRT). Polycrystal Inconel 718 was used as a case study to characterize the severe deformation and fracture behavior of materials. Based on the digital image correlation (DIC) technique and microscopic images taken by the MQSC test rig, the strain and stress fields were obtained to characterize the grain deformation and fracture state at the grain scale. It was found that the fracture mechanisms of Ni-based superalloy can be divided into severe shear-induced fracture and void-crack-induced fracture under severe shear deformation. The SMRT testing method provides a more intense shear and compressive deformation state, offering new insights into the behavior of grains under extreme deformation conditions.","PeriodicalId":344,"journal":{"name":"Journal of Alloys and Compounds","volume":"647 1","pages":""},"PeriodicalIF":6.2,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144533930","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}

Particularly, multilayers were extensively studied to produce an efficient spin torque switching with tunable perpendicular magnetic anisotropy. From the literature, the general research regarding magnetic dynamics and magnetic anisotropy by microwave-dependent magnetic measurements of Co/Ni in alloy form remains limited. Here we report on the magnetic dynamics and magnetic domain formation for Co₂Ni/Si(100). As the Co₂Ni thickness increases, magnetic domains change from random sizes to stripe shape at magnetic field close to the coercive field. By considering effective anisotropy energy and exchange stiffness constant, the critical thickness could be calculated to be around 19<!-- --> <!-- -->nm that is comparable to experimental result of the occurrence of magnetic domains with a striped shape. The trend of the higher resonance magnetic fields for larger polar angle could be explained by the finding that the easy axis of magnetization is more preferred to the surface normal to the film. By considering the intrinsic damping contribution in the linewidth, the damping coefficient for Co₂Ni can be determined here and shows the inhomogeneity influencing the magnetization alignment in the films. Our research work on the magnetic dynamics of Co₂Ni may pave the way to further applications of magnetic alloy on microwave-based spintronic devices.","PeriodicalId":344,"journal":{"name":"Journal of Alloys and Compounds","volume":"8 1","pages":""},"PeriodicalIF":6.2,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144533933","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, [Pd₃Cl(PPh₂)₂(PPh₃)₃]⁺ (Pd₃) nanoclusters stabilized by triphenylphosphine were successfully deposited into ZIF-67 via an in-situ synthesis approach. A series of Pd₃@ZIF-67 derivatives with low palladium loading were subsequently prepared through heat treatment at varying temperatures (Pd₃@ZIF-67-100, Pd₃@ZIF-67-200, Pd₃@ZIF-67-300, Pd₃@ZIF-67-400, Pd₃@ZIF-67-500, and Pd₃@ZIF-67-600). The influence of varying heat treatment temperatures on the hydrolytic activity of AB catalyzed by the Pd₃@ZIF-67-derived nanocatalyst was systematically investigated. The results show that the Pd₃@ZIF-67 derived catalyst exhibits excellent catalytic activity due to the presence of a synergistic effect of palladium and Co₃O₄.

As the calcination temperature rises, the structure of the Pd₃@ZIF-67 derived catalyst undergoes a gradual transformation from a complete framework to partial collapse and finally reconstruction. Structural changes led to a distinct \"volcanic\" tendency in the catalytic activity of Pd₃@ZIF-67 derived catalysts.
