Dynamic mechanical measurements were performed on a series of strong and fragile metallic glass-forming liquids in isochronous isothermal routes. Our results indicate that slow $\ensuremath{\beta}$-relaxation mode is ubiquitous systems though it may manifest as an excess wing glasses due to coupling with the $\ensuremath{\alpha}$-relaxation. Furthermore, we find degree between $\ensuremath{\alpha}$-relaxation correlates fragility these liquids. The possible mechanism connections are discussed.
Low-dimensional nanostructures of $\mathrm{Sn}{\mathrm{O}}_{2}$ thin films with the interesting features tetragonal rutile structure have been prepared by pulsed laser deposition. The microstructural evolution nanocrystalline has investigated using x-ray diffraction, transmission electron microscopy, high-resolution and Raman spectroscopy. Experimental results indicate that as-prepared appear to be polycrystalline state, a large amount defects, such as oxygen vacancies, vacancy clusters,...
Tin dioxide (SnO2) and graphene are unique strategic functional materials with widespread technological applications, particularly in the areas of solar batteries, optoelectronic devices, solid-state gas sensors owing to advances optical electronic properties. Versatile strategies for microstructural evolution related performance SnO2 composites fundamental importance development electrode materials. Here we report that a novel composite, quantum dots (QDs) supported by nanosheets (GNSs),...
To obtain a highly efficient and stable heterogeneous catalyst in catalytic wet hydrogen peroxide oxidation, we have successfully synthesized hierarchical mesoporous manganese dioxide (MnO2) superstructures by facile environmental friendly method on soft-interface between CH2Cl2 H2O without templates. The main crystal phase of as-prepared MnO2 was proved to be ε-MnO2 X-ray diffraction techniques. structure characterizations indicated that the were composed urchin-like hollow submicrospheres...
In this work, a novel catalyst, Fe-species-loaded mesoporous manganese dioxide (Fe/M-MnO2) urchinlike superstructures, has been fabricated successfully in two-step technique. First, (M-MnO2) superstructures have synthesized by facile method on soft interface between CH2Cl2 and H2O without templates. Then the M-MnO2-immobilized iron oxide catalyst was obtained through wetness impregnation calcination. Microstructural analysis indicated that M-MnO2 composed of hollow submicrospheres assembled...
A machine learning (ML) method aided by domain knowledge was proposed to predict saturated magnetization (Bs) and critical diameter (Dmax) of soft magnetic metallic glasses (MGs). Two datasets were established based on published experimental works about MGs. general feature space proven be adaptive for ML model training different prediction tasks. It demonstrated that the predictive performance models better than traditional knowledge-based estimation methods. In addition, design can greatly...
Zr 48.5 Cu 46.5 Al 5 bulk metallic glass matrix composites with diameters of 3 and 4mm were produced through water-cooled copper mold casting. Micrometer-sized bcc based B2 structured CuZr phase containing martensite plate, together some densely distributed nanocrystalline Zr2Cu plate-like Cu10Zr7 compound, was found embedded in a glassy matrix. The microstructure formation strongly depends on the composition cooling rate. Room temperature compression tests reveal significant strain...
