Summary: Bioactive glass scaffolds are commonly used in bone tissue engineering applications, and sintering is often employed to enhance their mechanical strength. However, sintering can lead to crystallization, resulting in reduced bioactivity and biodegradability. This study compared the in-vitro bioactivity and biodegradability of sintered 58S bioactive glass made from fully amorphous powder and partially crystalline powder with the same chemical compositions. The results showed that the sintered 58S produced from glass ceramic powder exhibited higher in-vitro bioactivity and biodegradability rate than that from fully amorphous powder. The initial structure after calcination was found to be crucial in determining the subsequent crystallization during sintering, and the presence of crystallinity and hydroxyapatite formation after calcination played important roles in increasing the bioactivity and biodegradability rate of the sintered 58S.

Summary: This study investigates the influence of alkali impurities and silica content in rice husk ash (RHA) on the alkali silica reaction (ASR) of mortar. Three types of RHAs with varying alkali content and amorphous silica were used. The study analyzes the effect of RHA type, particle size, and substitution proportion on mechanical properties and expansion level of mortar. It also examines the impact of RHA type on hydration products, hydrates pattern, and pore structure. The results indicate that RHA particle size and amorphous silica content are key factors affecting the compressive strength of mortar blended with RHA. An innovative finding suggests that RHA particles can act as reactive aggregates, reacting with potassium and alkali ions to create alkali silica gel. The mechanism for pozzolanic reaction and two ASRs in RHA is presented. Two ASRs were observed in GRHA particles, leading to significant expansion and cracks in mortar, while WRHA only reacted with alkali ions, resulting in slight expansion and no cracks in mortar. Overall, the importance of this paper is rated 8 out of 10.

Summary: Biogenic silica nanoparticles extracted from rice husks are a promising alternative to synthetic silica for column chromatography due to their highly active, polar, and porous nanostructure. In this study, highly pure amorphous bSNPs synthesized from rice husks showed excellent performance in separating ortho- and para-nitrophenol and nitroaniline. These findings suggest that rice husks can serve as an alternative silica source for column chromatography.

Summary: This study aims to improve the mechanical properties and durability of alkali-activated slag concrete (AASC) by introducing rice husk ash (RHA) and silica fume (SF). The experimental results suggest that RHA and SF can substantially enhance the physical, mechanical, and durability properties of AASC. The study also finds that RHA has a more significant effect, possibly due to its higher silica content and finer particle size.

Summary: This study investigates the influence of adding rice husk ash (RHA) and nano silica (NS) on the strength and durability properties of Portland cement (PC) mixture. The results show that the samples containing NS have significantly improved compressive strength. The highest compressive strength and flexural strength are found in the PC-based mixture containing 10% RHA and 3% NS after 28 days. Additionally, this composition also exhibits reduced water absorption and mass loss under acid attack. The combination of 10% RHA and 3% NS shows a positive contribution to the durability properties.

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 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.
