Summary: This study reported a simple and relatively low-temperature method to produce lignin-based graphene-like carbon materials. A lignin-based graphene-like film with micron thickness was successfully prepared by carbonization at a relatively low temperature using alkali lignin as a solid carbon source and metal Ni sheets as a catalyst. The research further explained the structural changes of alkali lignin and the growth process of the crystal nucleus through characterization studies of the obtained products at different temperatures. The process converted biomass resource into high value-added carbon material products, alleviating the current problems of energy consumption and climate pollution.

Summary: Silica and polystyrene spheres with a small size ratio (r = 0.005) were assembled into a binary colloidal crystal through sequential hanging drop self-assembly. The crystal could undergo calcination to transform into a silica-ordered concavity array, which exhibited light Bragg diffraction and shape dependent optical phenomena. Moreover, it could be further transformed into inverse-opal structures. Hierarchical 2D and 3D super-structures with ordered concavities as structural units were successfully fabricated in this study.

Summary: The structural and magnetic properties of iron oxide nanoparticles synthesized by laser pyrolysis, as well as their chitosan-stabilized aqueous suspensions, were studied with varying ratios of O-2 and Ar. It was found that lower O-2 concentrations resulted in the formation of smaller particles, while higher O-2 concentrations led to larger particles with higher magnetization saturation. The main components of all samples were identified as maghemite and/or magnetite phases, with minor presence of iron/iron carbides observed in all samples except for one.

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.
