Summary: The experimental investigation on the application of LBMM-mu EDM technique on stainless steel revealed the significant influence of laser input parameters, particularly scanning speed and power, on the performance of mu EDM. It was found that adjusting these laser parameters could either slow down or speed up the mu EDM processing time. The sequential machining technique was shown to reduce machining time, tool wear, and instability, while maintaining hole quality, compared to pure mu EDM process.

Summary: The study found that square microstructures were able to fully recover even after multiple cycles, while triangular microstructures lost their structural integrity after multiple deformations. Porous nanostructures showed poor recovery over repeated deformations. The differences in recovery capabilities for different structures are attributed to the elongation of geometrical features during deformation.

Summary: The performance of microchannels is influenced by their geometry, dimensions, and surface quality. Laser micro-milling (LMM), conventional micromilling (CMM), micro-forming, and chemical etching are commonly used methods for manufacturing microchannels. The challenges in these methods include non-uniform dimensions, tapering effect, low aspect ratio, tool wear, and burr formation. To address these challenges, hybrid micro milling techniques have been proposed, including laser pre-channel micro milling (LPCMM) and laser assisted sequential micro milling (LASMM). Experimental results showed that the hybrid methods achieved improvements in burr width and cutting force, but slightly increased surface roughness.

Summary: This paper explicitly considers the experimentally observed significant increase in yield stress for strain rates beyond 104 s-1 in laser shock processing (LSP) simulations. A combined numerical-analytical approach is used to predict the time evolution of plastic strain, and experimental validation is conducted. The results challenge the conventionally accepted strain rate range in LSP and highlight the importance of pressure decay in LSP treatments.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.

Summary: In the study of BM-SCO and HSCO thin films, it was found that H vacancies tend to prefer sites near the external surface or oxygen vacancy channels (OVCs), while H interstitials prefer sites of oxygen on a layer that contains six-fold coordinated Co. These findings not only enrich the understanding of complex surface phenomena of defect formation but also provide an explanation for the reversibility during phase transformation.

Summary: In this study, a potential platform to enhance Raman scattering and increase the number of observable Raman modes in monolayer transition metal dichalcogenides (TMDs) was proposed. The platform consisted of large-scale arrays of gold micropillars (MPs), which were able to enhance the Raman intensity of TMDs and make difficult-to-detect Raman modes observable. The platform showed great industrial advantages and wide applicability due to its low cost, simple process, large controllable area, and short process time.
