3D characterisation of dry powder inhaler formulations

3D characterisation of dry powder inhaler formulations

Carrier-based dry powder inhaler (DPI) formulations need to be accurately characterised for their particle size distributions, surface roughnesses, fines contents and flow properties. Understanding the micro-structure of the powder formulation is crucial, yet current characterisation methods give incomplete information. Commonly used techniques like laser diffraction (LD) and optical microscopy (OM) are limited due to the assumption of sphericity and can give variable results depending on par... Read more

X-ray Micro-Computed Tomography of Polymer Electrolyte Fuel Cells: What is the Representative Elementary Area?

X-ray Micro-Computed Tomography of Polymer Electrolyte Fuel Cells: What is the Representative Elementary Area?

With the growing use of X-ray computed tomography (X-ray CT) datasets for modelling of transport properties, comes the need to define the representative elementary volume (REV) if considering three dimensions or the representative elementary area (REA) if considering two dimensions. The resolution used for imaging must be suited to the features of interest in the sample and the region-of-interest must be sufficiently large to capture key information. Polymer electrolyte fuel cells have a hier... Read more

An Anisotropic Microstructure Evolution in a Solid Oxide Fuel Cell Anode

An Anisotropic Microstructure Evolution in a Solid Oxide Fuel Cell Anode

A solid oxide fuel cell (SOFC) is an electrochemical device that converts the chemical energy of hydrogen directly into electricity. A single cell usually has a form of a flat plate in which an impervious and dense ion-conducting electrolyte is sandwiched between two porous catalytic electrodes: an anode and a cathode. Fuel is fed to the anode side, and the air is supplied to the cathode. The gasses cannot mix to avoid unproductive combustion. Instead, gasses hit catalyst material, lose their... Read more

A Neutron Tomographic Analysis of Plated Silver Coins from Ancient Greece Official or Illegal?

A Neutron Tomographic Analysis of Plated Silver Coins from Ancient Greece Official or Illegal?

In the 6th century BC different techniques of coin manufacture were employed by mints in mainland Greece and in the Greek colonies in Southern Italy. In Greece these techniques were evidently derived from the Lydians and consisted in striking a piece of cast metal of predetermined weight (a ‘blank’ or flan) between two engraved dies made of hardened bronze. Colonies in Magna Graecia, however, uniquely developed another set of minting techniques to produce what today is called incuse coina... Read more

Towards digital metal additive manufacturing via high-temperature drop-on-demand jetting

Towards digital metal additive manufacturing via high-temperature drop-on-demand jetting

Drop-on-demand jetting of metals offers a fully digital manufacturing approach to surpass the limitations of the current generation powder-based additive manufacturing technologies. However, research on this topic has been restricted mainly to near-net shaping of relatively low melting temperature metals. Here it is proposed a novel approach to jet molten metals at high-temperatures (>1000 °C) to enable the direct digital additive fabrication of micro- to macro-scale objects. […] ... Read more

Fragmentation of wall rock garnets during deep crustal earthquakes

Fragmentation of wall rock garnets during deep crustal earthquakes

Deformation of the lithosphere by seismic slip along faults dissipates energy to the immediate surroundings as heat and elastic waves. Heat effects may occasionally cause frictional melting along the slip plane, leading to the formation of pseudotachylite, a characteristic fine-grained or glassy fault rock, interpreted as the quenched melt. Recently, it has been suggested that mechanical effects due to rapid loading, such as the formation of shiny “mirror” surfaces or pulverization of roc... Read more
