The Ebola virus VP40 matrix layer undergoes endosomal disassembly essential for membrane fusion

The Ebola virus VP40 matrix layer undergoes endosomal disassembly essential for membrane fusion

Ebola viruses (EBOVs) assemble into filamentous virions, whose shape and stability are determined by the matrix viral protein 40 (VP40). Virus entry into host cells occurs via membrane fusion in late endosomes; however, the mechanism of how the remarkably long virions undergo uncoating, including virion disassembly and nucleocapsid release into the cytosol, remains unknown. Here, we investigate the structural architecture of EBOVs entering host cells and discover that the VP40 matrix disassem... Read more

Over the rainbow? Micro-CT scanning to non-destructively study Roman and early medieval glass bead manufacture

The usefulness of desktop Micro-CT scanners for the study of archaeological artefacts is demonstrated in a non-destructive study of manufacturing methods of Roman and Early Medieval monochrome and polychrome glass beads. Differences in glass colours show up in these scans as differences in attenuation. The presence and distribution of bubbles and various inclusions (metal, opacifier) are also well visible. Shaft shapes and patterns of bubbles inside the glass make it possible in most cases to... Read more

Improving microstructural quantification in FIB/SEM nanotomography

Improving microstructural quantification in FIB/SEM nanotomography

Advanced nanotomographic analysis is still far from routine, and a number of challenges remain in data acquisition and post-processing. In this work, we present a number of techniques to improve the quality of the acquired data, together with easy-to-implement methods to obtain “advanced” microstructural quantifications. The techniques are applied to a solid oxide fuel cell cathode of interest to the electrochemistry community, but the methodologies are easily adaptable to a wide range of... Read more

Investigation of Hot Pressed Polymer Electrolyte Fuel Cell Assemblies via X-ray Computed Tomography

Investigation of Hot Pressed Polymer Electrolyte Fuel Cell Assemblies via X-ray Computed Tomography

The hot pressing process for fabricating membrane electrode assemblies (MEAs) has been widely adopted, yet little is known of its effects on the microstructural properties of the different components of the MEA. In particular, the interaction of the electrolyte, electrode and gas diffusion layer (GDL) due to lamination is difficult to probe as conventional imaging techniques cannot access the internal structure of the MEA. Here, a novel approach is used, which combines characterisation of hot... Read more

Characterization of the bone marrow adipocyte niche with three-dimensional electron microscopy

Characterization of the bone marrow adipocyte niche with three-dimensional electron microscopy

Unlike white and brown adipose tissues, the bone marrow adipocyte (BMA) exists in a microenvironment containing unique populations of hematopoietic and skeletal cells.

To study this microenvironment at the subcellular level, we performed a three-dimensional analysis of the ultrastructure of the BMA niche with focused ion beam scanning electron microscopy (FIB-SEM). This revealed that BMAs display hallmarks of metabolically active cells including polarized lipid deposits, a dense mitoch... Read more

Spiny fruits revealed by nano-CT scanning: Pseudoanacardium peruvianum (Berry) gen. et comb. nov. from the early Oligocene Belén flora of Peru

Spiny fruits revealed by nano-CT scanning: Pseudoanacardium peruvianum (Berry) gen. et comb. nov. from the early Oligocene Belén flora of Peru

Fossil fruits formerly described as cashews from the Oligocene of Peru are reinvestigated based on the original specimens and newly collected materials. The recovery of an outer spiny layer, preserved in the sedimentary molds surrounding the locule casts, indicates that these disseminules do not represent Anacardium. Imagery from nano-CT scans of the specimens documents a distinctive morphology which does not resemble any fruits or seeds of Anacardiaceae. We describe the morphology in more de... Read more

Tomographic investigation of the effects of second phases on the biodegradation and nano-mechanical performance of a Mg-Zn-Ca alloy

Tomographic investigation of the effects of second phases on the biodegradation and nano-mechanical performance of a Mg-Zn-Ca alloy

A combination of 3D tomography techniques provides direct evidence that links the phase assemblage to the bio-corrosion behaviour of a magnesium-zinc-calcium (Mg-Zn-Ca) alloy. The true shape, connectivity and volume fraction of the components have been determined using focused ion beam (FIB) tomography. The mechanism of the effect of the components with different morphologies on biodegradation was studied with the help of FIB. Micro X-ray CT (MicroCT) was used to investigate the degradation o...

Three-dimensional thermal stress analysis of the re-oxidized Ni-YSZ anode functional layer in solid oxide fuel cells

Three-dimensional thermal stress analysis of the re-oxidized Ni-YSZ anode functional layer in solid oxide fuel cells

Nickel-yttria-stabilized zirconia (Ni-YSZ) cermet is widely used as an anode material in solid oxide fuel cells (SOFCs); however, Ni re-oxidation causes critical problems due to volume expansion, which causes high thermal stress. We fabricated a Ni-YSZ anode functional layer (AFL), which is an essential component in high-performance SOFCs, and re-oxidized it to investigate the related three-dimensional (3D) microstructural and thermo-mechanical effects. A 3D model of the re-oxidized AFL ... Read more

High performance anode with dendritic porous structure for low temperature solid oxide fuel cells

High performance anode with dendritic porous structure for low temperature solid oxide fuel cells

A dendritic porous supported microstructure simultaneously creates small pore size and broad gas diffusion pathways in a solid oxide fuel cell anode membrane. This microstructure also achieves pore sizes that reduce with increasing depth within the membrane without increasing the structure tortuosity. Such a microstructure supplies high triple phase boundary density, fast gas diffusion and low polarization resistance. Here we characterise the performance of a porous anode with such a dendriti...

Mesoscale characterization of local property distributions in heterogeneous electrodes

Mesoscale characterization of local property distributions in heterogeneous electrodes

The performance of electrochemical devices depends on the three-dimensional (3D) distributions of microstructural features in their electrodes. Several mature methods exist to characterize 3D microstructures over the microscale (tens of microns), which are useful in understanding homogeneous electrodes. However, methods that capture mesoscale (hundreds of microns) volumes at appropriate resolution (tens of nm) are lacking, though they are needed to understand more common, less ideal electrode...
