Summary: In this paper, inkjet-printed silver thin films with crack-inducing underlayers were reported to enhance the sensitivity of resistance changes under deformation. The highly sensitive strain sensors can detect weak vertical forces even through thick plates, such as polyethylene terephthalate or glass. These sensors can potentially solve the accuracy issue of wearable devices by accurately detecting biosignals such as heart rate and blood pressure even when off-centered from the artery.

Summary: A mathematical model is developed to predict the maximum speed of a focused laser beam in cutting thin materials. The model, based on only two material parameters, establishes an explicit relationship between cutting speed and laser parameters. It reveals that there is an optimal focal spot radius, leading to maximized cutting speed for a given laser power. Comparison between modeling results and experiments, after correcting laser fluence, shows good agreement. This study is significant for the practical application of lasers in processing thin materials such as sheets and panels.

Summary: In the current research environment, the decrease in laser ablation efficiency for pulse durations exceeding a few picoseconds remains an unresolved question. A heuristic approach is used to understand the role of effective penetration depth on ablation efficiency. By considering the mechanical surface expansion during pulse irradiation, the relationship between ablation efficiency and pulse duration is deciphered. Single-pulse ablation efficiency experiments of the CrMnFeCoNi alloy are reported, supporting the proposed model.

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.
