Summary: The current challenges in dewatering oil sand mature fine tailings by flocculation using a single flocculant include the requirement of very high doses and high cost, inefficient flocculation, and low content of solids in sediment. It has been found that using dual polymers in combination with varying sand-to-fines ratios can improve flocculation efficiency and increase solid content in the sediment.

Summary: This paper investigates the application of electrochemical chloride extraction (ECE) technology in sea-sand concrete. It demonstrates that utilizing a strong electric field can effectively reduce the chloride ion content, improve the durability performance, and enhance the mechanical properties of the concrete columns. The research findings indicate that the strong electric field with specific electrifying time can significantly enhance the efficiency of ECE, meeting the required specifications for chloride ion content. Additionally, standard curing for 28 days further increases the ultimate bearing capacity of the electrified concrete columns.

Summary: Binder Jet Additive Manufacturing (BJAM) is a versatile technique that can form complex geometries using a variety of powdered materials, with the discovery of a versatile polyethyleneimine (PEI) binder improving the flexural strength of parts significantly. Through secondary infiltration with ethyl cyanoacrylate, the flexural strength of the printed parts can be further increased. This technology has the potential to revolutionize various applications including construction and tooling.

Summary: Diatom frustules, made of hydrated silica, are unicellular eukaryotic microalgae widely distributed in aquatic environments, and are considered sustainable sources for industrial applications due to their high biocompatibility and surface functionalisation ease. Although suitable for biomedical applications, biosilica frustules have not yet been officially recognized as safe by governmental food and medical agencies.
