A generalized hydrothermal strategy for fabricating three-dimensional (3D) battery electrodes is presented. The hydrothermal growth deposits electrochemically active nanomaterials uniformly throughout the complex 3D mesostructure of the scaffold. Ni inverse opals coated with SnO2 nanoparticles or Co3O4 nanoplatelets, and SiO2 inverse opals coated with Fe3O4 are fabricated, all of which show att...

The shear response of a model polymer–clay gel is measured using small-angle neutron and light scattering, optical microscopy, and rheometry. As the flow disrupts the transient network that forms between clay and polymer, coupling between composition and stress leads to the formation of a macroscopic domain pattern, while the clay platelets orient with their surface normal parallel to the direc...

Continuous-fiber-reinforced ceramic matrix composites (CMC) have been proposed as candidates for high-temperature applications. Their architecture and network of porosity have a strong effect on the mechanical behavior. X-ray tomography is a non-destructive technique that allows studying the volume mesostructure of these porous materials. The volume porosity, the open porosity fraction, the con...

In confined flows of initially homogenous nematic polymers, a key factor in the evolution of mesostructure is the likely timescale, denoted by ÆtæA, on which monodomain mesophase attracting states, denoted by A, are resonated by the imposed flow. These monodomain modes (flow-aligning (FA), logrolling (LR), tumbling Xiaoyu Zheng M. Gregory Forest Ruhai Zhou Qi Wang Likelihood and expected-time s...

This paper presents a meso-scale modelling framework to investigate the fracture process in concrete subjected uniaxial and biaxial compression accounting for its mesostructural characteristics. 3D mesostructure of consisting coarse aggregates, mortar interfacial transition zone between them was developed using an in-house code based on Voronoi tessellation splining method, which enables genera...

In this work, a magnetic Fe3O4@SiO2@mesoporous-SiO2 (F@S@m-S) material was successfully prepared by three-step method: firstly, Fe3O4 particles were synthesized through hydro-thermal synthesis process; secondly, Fe3O4@SiO2 materials fabricated via template method using tetraethyl orthosilicate (TEOS) as silicon sources and cetyltrimethylammonium chloride (CTAC) templates; lastly, F@S@m-S well. ...

The calendering process aims at enhancing the electrode energy density, and improving electronic conductivity, determines final porous micro/mesostructure. In this sense, one of main parameters interest is its impact in porosity (?) electrochemical performance. Here, we present a systematic study conditions (applied calender pressure roll temperature) effect on NMC-based electrodes ? terms acti...
