Strengthening mechanisms in Fe-Al based ferritic low-density steels
Low-density steels with different aluminium contents have been investigated with an aim to examine the occurrence of different strengthening mechanisms leading to its higher strength. A composition corresponding to 6.8wt% aluminium has been studied to understand the underlying strengthening mechanisms. Different factors contributing to the strengthening mechanisms have been separately…

Ordered Mesoporous to Macroporous Oxides with Tunable Isomorphic Architectures: Solution Criteria for Persistent Micelle Templates
Lokupitiya, Hasala N.; Jones, Alexis; Reid, Barry; Guldin, Stefan; Stefik, Morgan
Porous and nanoscale architectures of inorganic materials have become crucial for a range of energy and catalysis applications, where the ability to control the morphology largely determines the transport characteristics and device performance. Despite the availability of a range of block copolymer self-assembly methods, the conditions for tuning the key…

Blocked Shape Memory Effect in Negative Poisson’s Ratio Polymer Metamaterials
Boba, Katarzyna; Bianchi, Matteo; McCombe, Greg; Gatt, Ruben; Griffin, Anselm C.; Richardson, Robert M.; Scarpa, Fabrizio; Hamerton, Ian; Grima, Joseph N.
We describe a new class of negative Poisson’s ratio (NPR) open cell PU–PE foams produced by blocking the shape memory effect in the polymer. Contrary to classical NPR open cell thermoset and thermoplastic foams that return to their auxetic phase after reheating (and therefore limit their use in technological applications),…
Monodisperse hollow silica spheres: An in-depth scattering analysis
Ruckdeschel, Pia; Dulle, Martin; Honold, Tobias; Förster, Stephan; Karg, Matthias; Retsch, Markus
Herein, we fabricate hollow silica nanoparticles with exceptionally narrow size distributions that inherently possess two distinct length scales—tens of nanometers with regards to the shell thickness, and hundreds of nanometers in regards to the total diameter. We characterize these structures using dynamic and static light scattering (DLS and SLS), small…
Rheological Link Between Polymer Melts with a High Molecular Weight Tail and Enhanced Formation of Shish-Kebabs
Wingstrand, Sara L.; Shen, Bo; Kornfield, Julie A.; Mortensen, Kell; Parisi, Daniele; Vlassopoulos, Dimitris; Hassager, Ole
Presence of an ultra high molecular weight (UHMw) fraction in flowing polymer melts is known to facilitate formation of oriented crystalline structures significantly. The UHMw fraction manifests itself as a minor tail in the molar mass distribution and is hardly detectable in the canonical characterization methods. In this study, alternatively,…
Polymer-Grafted Nanoparticle Membranes with Controllable Free Volume
Bilchak, Connor R.; Buenning, Eileen; Asai, Makoto; Zhang, Kai; Durning, Christopher J.; Kumar, Sanat K.; Huang, Yucheng; Benicewicz, Brian C.; Gidley, David W.; Cheng, Shiwang; Sokolov, Alexei P.; Minelli, Matteo; Doghieri, Ferruccio
Polymer-based membranes play a key role in several industrially important gas separation technologies, e.g., removing CO2 from natural gas, with enormous economic and environmental impact. Here, we develop a novel hybrid membrane construct comprised entirely of nanoparticles grafted with polymers. These membranes are shown to have broadly tunable separation performance…
Phosphorylation-induced conformational dynamics in an intrinsically disordered protein and potential role in phenotypic heterogeneity
Kulkarni, Prakash; Jolly, Mohit Kumar; Jia, Dongya; Mooney, Steven M.; Bhargava, Ajay; Kagohara, Luciane T.; Chen, Yihong; Hao, Pengyu; He, Yanan; Veltri, Robert W.; Grishaev, Alexander; Weninger, Keith; Levine, Herbert; Orban, John
Intrinsically disordered proteins (IDPs) that lack a unique 3D structure and comprise a large fraction of the human proteome play important roles in numerous cellular functions. Prostate-Associated Gene 4 (PAGE4) is an IDP that acts as a potentiator of the Activator Protein-1 (AP-1) transcription factor. Homeodomain-Interacting Protein Kinase 1 (HIPK1)…
