Until March 2021, around 120 million coronavirus disease (COVID-19) infected cases and over 2.6 million deaths have been reported worldwide. […] Recent investigations have implied that face masks help to reduce the disease transmission and therefore slow down the growth of the epidemic curve. However, there are still ongoing debates on the efficacy of wearing masks […] since there is a general lack of information relating to the material structure of commonly used face masks.Read more

In biomedical research, a huge variety of different techniques is currently available for the structural examination of small specimens, including conventional light microscopy (LM), transmission electron microscopy (TEM), confocal laser scanning microscopy (CLSM), microscopic X-ray computed tomography (microCT), and many others. Since every imaging method is physically limited by certain parameters, a correlative use of complementary methods often yields a significant broader range of inform... Read more

Nowadays, industrial processes demand materials with specific properties and localized microstructures to improve material performance. To satisfy particular needs, the development of materials with changing mechanical properties and/or microstructures along a preferential direction has been developed. These are called Functional Graded Materials (FGMs). Among these materials, a variation on the porosity along the part is very useful for different industrial applications, such as microfiltrat...

In China’s energy consumption structure, coal is the main energy source, accounting for about 60% of primary energy consumption. Coal is a porous medium with complex pore structures. Nanopore structure in coal particle is the basic underlying factor driving coal particle strength. A better knowledge of nanopore structure – coal particle strength correlation is of great significance for coal mining and other fields of engineering problems.

The microstructure morphologies have been characterized by high resolution laboratory X-ray computed tomography in Carbon Fiber Reinforced Carbon and Silicon Carbide (C/C-SiC) ceramic composites fabricated by Gaseous Silicon Infiltration (GSI) from C/C preforms of three different architectures: 3D stitched cloth fabric; 3D orthogonal woven fabric; and needled short-cut felt. Each composites’ microstructure was influenced by the structure of the C/C preform. By incorporating tomography with ... Read more

The electrode microstructural properties significantly influence the efficiency and durability of many electrochemical devices including solid oxide fuel cells. Despite the possibility of simulating the electrochemical phenomena within real three-dimensional microstructures, the potential of such 3D microstructural information has not yet been fully exploited. We introduce here a completely new methodology for the advanced characterization of inhomogeneous current distribution base... Read more

Podocytes present a unique 3D architecture specialized for glomerular filtration. However, several 3D morphological aspects on podocyte development remain partially understood because they are difficult to reveal using conventional scanning electron microscopy (SEM). Here, we adopted serial block-face SEM imaging…

The porous transport layer (PTL) is a vital component of the polymer electrolyte membrane water electrolyser (PEMWE) as it is both a conduit for current distribution and mass transport. This study aims to examine the influence of the microstructure of the PTL on the performance of a PEMWE by the combination of ex-situ and in-situ techniques. Two PTLs with distinctly different mean pore diameter were characterized to determine key properties such as surface morphology, porosity, pore size dist... Read more

The electrochemical performance of Ni-YSZ SOFC anodes can quickly degrade during redox cycling. Mechanical damage at interfaces significantly decreases the number of active triple phase boundaries. This study firstly focuses on the sintering temperature impact on YSZ scaffold mechanical properties. The YSZ scaffold sintered at 1200 °C exhibited 56% Read more

Nickel/zirconia-based nanostructured electrodes for solid oxide fuel cells suffer from poor stability even at intermediate temperature.

This study quantifies the electrochemical and microstructural degradation of nanostructured electrodes by combining 3D tomography, electrochemical impedance spectroscopy (EIS) and mechanistic modeling. For the first time, the electrochemical degradation of nanostructured electrodes is quantified according to the fractal nature of the three-phase bounda... Read more

A simple chemical bath deposition is used to coat a complex porous ceramic scaffold with a conformal Ni layer.

The resulting composite is used as a solid oxide fuel cell electrode, and its electrochemical response is measured in humidified hydrogen. X‐ray tomography is used to determine the microstructural characteristics of the uncoated and Ni‐coated porous structure, which include the surface area to total volume, the radial pore size, and the size of the necks between the pores....
