Yu, K. (author), Spiesz, E.M. (author), Balasubramanian, S. (author), Schmieden, D.T. (author), Meyer, Anne S. (author), Aubin-Tam, M.E. (author)Sustainable structural materials with excellent impact-resistance properties are urgently needed but challenging to produce, especially in a scalable fashion and with control over 3D shape. Here, we show that bacterial cellulose (BC) and bacterially precipitated calcium carbonate self-assemble into a layered structure reminiscent of tough...journal article 2021

Liang, K. (author), Spiesz, E.M. (author), Schmieden, D.T. (author), Xu, An Wu (author), Meyer, Anne S. (author), Aubin-Tam, M.E. (author)Graphene oxide (GO) has recently been highlighted as a promising multipurpose two-dimensional material. However, free-standing graphene oxide films suffer from poor strength and flexibility, which limits scaling-up of production and lifetime structural robustness in applications. Inspired by the relationship between the organic and inorganic...journal article 2020

Spiesz, E.M. (author), Schmieden, D.T. (author), Grande, Antonio M. (author), Liang, K. (author), Schwiedrzik, Jakob (author), Natalio, Filipe (author), Michler, Johann (author), Garcia, Santiago J. (author), Aubin-Tam, M.E. (author), Meyer, Anne S. (author)The impressive mechanical properties of natural composites, such as nacre, arise from their multiscale hierarchical structures, which span from nano- to macroscale and lead to effective energy dissipation. While some synthetic bioinspired materials have achieved the toughness of natural nacre, current production methods are complex and...journal article 2019

Lehner, B. (author), Janssen, V.A.E.C. (author), Spiesz, E.M. (author), Benz, D. (author), Brouns, S.J.J. (author), Meyer, Anne S. (author), van der Zant, H.S.J. (author)Graphene's maximized surface-to-volume ratio, high conductance, mechanical strength, and flexibility make it a promising nanomaterial. However, large-scale graphene production is typically cost-intensive. This manuscript describes a microbial reduction approach for producing graphene that utilizes the bacterium Shewanella oneidensis in...journal article 2019
