Magnesium (Mg) and its alloys have recently gained increasing attention in the biomedical field as promising biodegradable materials with harmless degradation products. Magnesium-based alloys have a wide range of biomedical applications because of their outstanding biocompatibility and unique mechanical properties. Widespread use of Mg-based biomedical devices eliminates the need for post-healing biomaterial removal surgery and minimizes the negative consequences of the implantation of permanent
Ni–Co-LDH has recently been examined for its potential as battery-type hybrid supercapacitors made from metal hydroxide electrode materials, due to their unique spatial structure, excellent electrochemical activity, and good electrical conductivity.
Using ground granulated blast-furnace slag (GGBS) under different alkaline conditions, we studied the mechanisms and extents of Cr(VI) reduction and sorption and compared them to reactions with Portland cement (PC). We also investigated the effects of mixing PC/GGBS ratios on Cr(VI) dissolution after carbonating the substrates. We observed a complete sorption and reduction of Cr(VI) to Cr(III) in a GGBS-in-Ca(OH)₂ solution (pH > ~12.5) after 10 h, whereas in distilled water (pH = ~11.5) GGBS exh
Morphological details of calcium silicate hydrate (C–S–H) stemming from the hydration process of Portland cement ( PC ) phases are crucial for understanding the PC ‐based systems but are still only partially known. Here we introduce the first soft X‐ray ptychographic imaging of tricalcium silicate (C 3 S) hydration products. The results are compared using both scanning transmission X‐ray and electron transmission microscopy data. The evidence shows that ptychography is a powerful method to visua
Abstract This study aims to elucidate the effect of heating on the local atomic arrangements, structure, phase transformation, and mechanical properties of synthesized calcium–silicate–hydrate (C–S–H). The alteration in the atomic arrangement of the synthesized C–S–H (Ca/Si =0.8) and the formation of crystalline phases that occurred in three distinct transformation stages of dehydration (105°C–200°C), decomposition (300°C–600°C), and recrystallization (700°C–1000°C) were investigated via powder
