Summary: There is a growing concern about antimicrobial resistant infections in healthcare settings. While bacterial infections are well-documented, fungal infections receive less attention despite their significant impact on society and potential lethality. Fungi share many biological features with humans, making it challenging to develop effective technologies and infrastructure for combating fungal infections. This study presents a novel antimicrobial surface modified with the broad-spectrum biocide chlorhexidine, which demonstrates rapid killing of the opportunistic fungal pathogens, Candida albicans and Cryptococcus neoformans, and outperforms current available technologies like silver and copper.

Summary: The effects of microstructure and reversed austenite on the hydrogen embrittlement behavior of NiCrMoV/Nb high-strength steel were investigated. The quenching and tempering steel showed the highest resistance to hydrogen embrittlement due to its lower hydrogen diffusion and higher apparent hydrogen concentration. The presence of reversed austenite in the quenching, lamellarizing, and tempering steel increased its susceptibility to hydrogen embrittlement.

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.
