Marine silicon for biomedical sustainability
BMEMat, EarlyView.Schematic illustrating marine silicon for biomedical engineering. Abstract Despite momentous divergence from oceanic origin, human beings and marine organisms exhibit elemental homology through silicon utilization. Notably, silicon serves as a critical constituent in multiple biomedical processes.

Service life estimation of cracked and healed concrete in marine environment [PDF]
, 2016 In the aggressive seawater environment, the durability of concrete is strongly influenced by the presence of chlorides and sulfates. Marine structures mostly have an important social function with a high economic impact, which makes durability a key ...

Carbon Energy, EarlyView.Operando Raman spectroscopy directly captures the dynamic form conditions of the BaCoO3‐δ phase on the BSCY surface. This observation provides critical insight into the phase evolution mechanisms, which are essential for optimizing the performance and stability of BSCY‐based protonic ceramic fuel cell cathodes.

Variable Temperature Studies of Two Calcium Uranates α‐Ca3UO6 and Ca2UO5
Chemistry – A European Journal, EarlyView.The structures and thermal responses of the calcium uranates α‐Ca3UO6 and Ca2UO5 were investigated using in situ synchrotron x‐ray diffraction and neutron powder diffraction. Despite the very similar chemical compositions, the structural response of the two calcium uranates is shown to be complex and varied.

Chemistry – A European Journal, EarlyView.A2.4Cr8Te14$A_{2.4}{\rm Cr}_{8}{\rm Te}_{14}$ (A = Rb, Cs) compounds exhibit a layered, ladder‐like Cr‐Te framework uniting structural motives of hollandite‐like and delafossite‐like phases. Alkali atoms are situated both in the interlayer space and tunnels within the Cr8Te14${\rm Cr}_{8}{\rm Te}_{14}$ framework.

The Canadian Journal of Chemical Engineering, EarlyView.Abstract Industrial wastewater contamination by azo dyes poses a significant environmental challenge. This study reports the green synthesis of bimetallic iron/nickel (Fe/Ni) nanoparticles using moringa leaf extract, which acted as both a reducing and capping agent, and their incorporation into polyethersulphone (PES) membranes to produce eco‐friendly ...
