The characterisation of porous crystalline solids often relies on single crystal X-ray diffraction, which does not give direct information about the surface of the material. Here, crystals of a porous organic cage, CC3-R, are investigated by atomic force microscopy and shown to possess two distinct gas-solid interfaces, proving that the bulk crystal structure is preserved at the porous crystal ...

Porous nanospheres have a wide range of applications such as in catalysis, separation and controlled delivery. Among these nanospheres, syntheses and applications of porous silica nanospheres have been investigated extensively. Uniform porous silica nanospheres can be synthesized using a modified Stöber method. In the present study, porous silica spheres were prepared in the pre-formed emulsion...

In this article, composites consisting of porous Ni cores coated with boehmite/nickel aluminum oxide nanoflakes were successfully prepared by a versatile method. The crystal constituents and shapes of the boehmite/nickel aluminum oxide nanoflakes were strongly influenced by reaction temperature, and their microwave absorption properties were investigated in terms of complex permittivity and per...

FEATURE ARTICLE Serena A. Corr et al. Spontaneously formed porous and composite materials PAPER Dan Du et al. One-step electrochemical deposition of Prussian Blue–multiwalled carbon nanotube nanocomposite thin film In recent years, a number of routes to porous materials have been developed which do not involve the use of pre-formed templates or structure-directing agents. These routes are usual...

This thesis details the process taken for the computational modelling of convective heat transfer in porous media with the objective of improving the accuracy of porous continuum models. CFD simulations were performed to predict convective heat transfer resulting from forced flow through highly conductive porous blocks. For the pore-level predictions, an idealized geometric model for spherical-...

A unique methodology of fabricating Si anodes for lithium-ion batteries with porous carbon scaffold structure is reported. Such carbon scaffold Si anodes are fabricated via carbonization of porous Si-PVdF precursors which are directly deposited on the current collector. Unlike the conventional slurry casting method, binder and conductive additives are not used in the preparation of the carbon s...

Porous anatase TiO(2) single crystal architectures with large specific surface area and remarkable crystalline phase-stability were fabricated via a green microwave-assisted process. Ionic liquid was chosen as both an essential structure-directing agent for the formation of the {001} facets exposed TiO(2) and an etching agent source for selective erosion of the exposed {001} facets, leading to ...

A photocatalytic reaction involves charge separation and transfer under photoirradiation, and the photogenerated charge carriers (holes and electrons) are responsible for the photocatalytic activity of the catalyst. The active centres in a single-site photocatalyst are the isolated and spatially separated sites that may interact with reactants after photo-irradiation. Generally, single-site pho...
