Tough Ordered Mesoporous Elastomeric Biomaterials Formed at Ambient Conditions

Rajasekharan, Anand K.; Gyllensten, Christoffer; Blomstrand, Edvin; Liebi, Marianne; Andersson, Martin

Synthetic dry elastomers are randomly cross-linked polymeric networks with isotropic and unordered higher-level structural features. However, their growing use as soft-tissue biomaterials has demanded the need for an ordered and anisotropic nano-micro (or) mesoarchitecture, which is crucial for imparting specific properties such as hierarchical toughening, anisotropic mechanics, sustained drug…

Macroscopic interpretation of nano-scale scattering data in clay

Birmpilis, G.; Ahmadi-Naghadeh, R.; Dijkstra, J.

The potential of X-ray scattering measurements for monitoring changes on the nano-scale in fine-grained materials in their natural wet state is demonstrated with a series of feasibility tests on well-controlled kaolin samples – that is, water content, pH and loading history. The results indicate that subtle changes on the nanometric…

A facile approach to thermomechanically enhanced fatty acid-containing bioplastics using metal–ligand coordination

Lamm, Meghan E.; Song, Lingzhi; Wang, Zhongkai; Lamm, Benjamin; Fu, Lin; Tang, Chuanbing

Biomass-based polymers show promise for the mitigation of environmental issues associated with petroleum-derived commodity polymers; however, due to poor entanglement, many of these polymers typically lack mechanical strength and toughness. Herein, we report a facile approach to utilizing metal–ligand coordination to create physical crosslinking, and thus chain entanglements for plant…

Application of Experimental Design to Hydrogen Storage: Optimisation of Lignin-Derived Carbons

Rowlandson, Jemma L.; Coombs OBrien, James; Edler, Karen J.; Tian, Mi; Ting, Valeska P.

Lignin is a significant by-product of the paper pulping and biofuel industries. Upgrading lignin to a high-value product is essential for the economic viability of biorefineries for bioethanol production and environmentally benign pulping processes. In this work, the feasibility of lignin-derived activated carbons for hydrogen storage was studied using a…

Synthesis, Modular Composition, and Electrochemical Properties of Lamellar Iron Sulfides

Horwitz, Noah E.; Shevchenko, Elena V.; Park, Jehee; Lee, Eungje; Xie, Jiaze; Filatov, Alexander S.; Anderson, John

Transition metal chalcogenides with layered structures have emerged as promising materials for energy storage, catalysis, and electronics, among other areas. We have identified a new layered phase of iron sulfide containing interlayer solvated cations. We present an optimized synthesis for the Li+-containing material from an Fe(III) xanthate complex. Structure and…
