Effect of Microstructure of Porous Transport Layer on Performance in Polymer Electrolyte Membrane Water Electrolyser

Effect of Microstructure of Porous Transport Layer on Performance in Polymer Electrolyte Membrane Water Electrolyser

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

A separated vortex ring underlies the flight of the dandelion

A separated vortex ring underlies the flight of the dandelion

Wind-dispersed plants have evolved ingenious ways to lift their seeds. The common dandelion uses a bundle of drag-enhancing bristles (the pappus) that helps to keep their seeds aloft. This passive flight mechanism is highly effective, enabling seed dispersal over formidable distances; however, the physics underpinning pappus-mediated flight remains unresolved. Here we visualized the flow around dandelion seeds, uncovering an extraordinary type of vortex. This vortex is a ring of recirculating... Read more

Partial dissolution of carbonate rock grains during reactive CO2-saturated brine injection under reservoir conditions

Partial dissolution of carbonate rock grains during reactive CO2-saturated brine injection under reservoir conditions

Our novel procedure of injecting oil after reactive transport has revealed previously unidentified (ghost) regions of partially-dissolved grains of carbonate rock. X-ray micro-tomography and FIB-SEM techniques were used to identify and resolve these ghost regions in three-dimensions at the nm- to µm-scale. Considering the solid part of the ghost regions as macro (bulk) pore space can result in the overestimation of porosity and permeability predi...

Laser-matter interactions in additive manufacturing of SS316L and 13-93 bioactive glass revealed by in situ X-ray imaging

Laser-matter interactions in additive manufacturing of SS316L and 13-93 bioactive glass revealed by in situ X-ray imaging

Laser-matter interactions in laser additive manufacturing (LAM) occur on short time scales (10-6 – 10-3 s) and have traditionally proven difficult to characterise. We investigate these interactions during LAM of stainless steel (SS316 L) and 13-93 bioactive glass powders using a custom built LAM process replicator (LAMPR) with in situ and operando synchrotron X-ray radiography. This reveals a range of melt track solidification phenomena as... Read more

REGIONAL DIVERSITY IN THE MURINE CORTICAL VASCULAR NETWORK IS REVEALED BY SYNCHROTRON X-RAY TOMOGRAPHY AND IS AMPLIFIED WITH AGE

REGIONAL DIVERSITY IN THE MURINE CORTICAL VASCULAR NETWORK IS REVEALED BY SYNCHROTRON X-RAY TOMOGRAPHY AND IS AMPLIFIED WITH AGE

Cortical bone is permeated by a system of pores, occupied by the blood supply and osteocytes. With ageing, bone mass reduction and disruption of the microstructure are associated with reduced vascular supply. Insight into the regulation of the blood supply to the bone could enhance the understanding of bone strength determinants and fracture healing. Using synchrotron radiation-based computed tomography, the distribution of vascular canals and osteocyte lacunae was assessed in murine cortica... Read more
