A process of micromolding, delivering micro- and nanopatterned ceramic surfaces for biomaterial applications is described in this work. To create the desired structures, tape casting of ceramic slurries on microfabricated silicon mold was used. Several tape casting slurry compositions were tested to evaluate the feasibility of transferring micro- and nano-features from silicon molds. Used ceram...

Bone's microporosity plays important biological and mechanical roles. Synchrotron radiation micro-computed tomography (SR CT) is considered the gold standard when evaluating osteocyte lacunae, vascular channels and their three-dimensional (3D) distribution, yet it is a rather exclusive technique. Here, we explored nondestructive desktop micro-computed tomography (desktop CT) as an alternative...

Inorganic micro®ltration membranes with a pore size down to 0.1 mm have been made using laser interference lithography and silicon micro machining technology. The membranes have an extremely small ̄ow resistance due to a thickness smaller than the pore size, a high porosity and a very narrow pore size distribution. They are relatively insensible to fouling, because they have a smooth surface, s...

This paper reviews the available methods to study thermal applications with open-cell metal foam. Both experimental and numerical work are discussed. For experimental research, the focus of this review is on the repeatability of the results. This is a major concern, as most studies only report the dependence of thermal properties on porosity and a number of pores per linear inch (PPI-value). A ...

In natural micro-nanoscale porous media, the movable fluid porosity can effectively represent storage and permeable properties, but various mineral compositions have complicated effects on it. Taking saline lacustrine shale as an example, this study researched of composition porosity, based nuclear magnetic resonance (NMR), focused ion beam (FIB), x-ray diffraction (XRD) experiments. The result...

The ability of a rock to store and flow fluids is dependent upon the pore volume, pore geometry and its connectivity. Carbonate rocks are inherently heterogeneous having been laid down in a range of depositional environments and having undergone significant diagenesis. They are particularly difficult to characterise as the pore sizes can vary over orders of magnitudes and connectivity of pores ...

One of the dominant approaches to tissue engineering is the seeding of biodegradable, biocompatible polymer scaffolds with progenitor cells prior to 3D culture or implantation. The microarchitecture of these scaffolds has direct effects upon the ability of cells to attach, migrate, and differentiate. Microtomographic (micro-CT) scanners enable high-speed 3D characterization of the salient featu...
