Summary: Densification of hydroxyapatite was achieved through cold sintering at temperatures below 200 ℃ with CaHPO4.2H2O as an additive. The influence of CaHPO4.2H2O content and temperature on the relative density of cold-sintered HA was investigated, with the elastic modulus, compressive strength, and flexural strength of the specimens slightly inferior to conventionally sintered dense HA. This strategy of densifying target products from their hydrated precursors presents a promising avenue for the development of cold sintering process.

Summary: In this study, it was discovered that mixing 2-(2-hydroxyphenyl)-1H-benzimidazole (HPBI) molecules with zeolitic imidazolate framework-8 (ZIF-8) colloidal suspensions resulted in significantly enhanced fluorescence. Through various techniques, it was found that HPBI molecules adsorbed onto the surface of ZIF-8 particles coordinatively and electrostatically, forming a new type of fluorescence emitter. These emitters were distributed periodically on the outer surface of ZIF-8 particles, with fixed distances smaller than the excitation light wavelength, suggesting the possibility of triggering collective spontaneous emission.

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.
