Nanoengineering of Metallic Glasses

“…[75][76][77] As shown in Figure 2a, the experimental steps on fabricating MGs with nanostructures by the TPF process can be divided as follows: 1) MGs and nanotemplates are stacked up and down on the heating stage; 2) pressure is applied to the MGs' surfaces after heating it to the SLR; and 3) there is release of the fabricated MGs with nanostructures by removing the nanotemplates. [78] The second step plays an important role in the TPF process for fabricating the MGs with nanostructures. In this step, factors such as temperature, pressure, time during the TPF process, forming size, etc.…”

“…[88][89][90] From the aforementioned work on MGs for TPF process, it can be seen that templates are an essential part for fabricating the MGs with nanostructures. The TPF templates currently used for the formation of MGs with nanostructures or atomic-scale structures are broadly the following: anodic aluminum oxide (AAO), [78] silicon (Si) templates, [85] bulk MG (BMG), [47] mica, [91] strontium titanate (STO), [75] lanthanum aluminate (LaAlO 3 ), [92] etc. Among these, Schroers et al used mica, STO, and LaAlO 3 as templates to achieve atomic precision on MGs by TPF process.…”

Exploring the physical origin of the electrocatalytic performance of an amorphous alloy catalyst via machine learning accelerated DFT study

“…8 Recently, we found experimentally that the amorphous alloy has an excellent Tafel coefficient and a self-stabilized performance in HER. 9,10 However, the relationship between the catalytic performance and the local atomic environment remain unresolved due to the method limitation in the experiment.…”

Manufacture of porous metallic glass using dissolvable templates

“…Owing to this feature, the advanced processing technology of MG thermoplastic forming (TPF) has been explored. To date, many micro/nanostructures have been achieved through TPF, such as nanowires [27,28], precision gratings [29,30], and precision microfluid [31]. However, the formation of hierarchical porous MGs is rarely reported due to the lack of templates and the difficulty of the preparation by other processes.…”
