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

Assessment of effective elastic properties and residual stresses in directionally solidified eutectic Al2O3/YAG/ZrO2 ceramics by finite element analysis

Assessment of effective elastic properties and residual stresses in directionally solidified eutectic Al2O3/YAG/ZrO2 ceramics by finite element analysis

Current materials such nickel based superalloys cannot be used anymore and new materials are thus considered. For the hottest parts of jet engines, eutectic ceramics have potentially interesting features. In order to assess the thermo-mechanical properties of this material, numerical multi-scale analyses may be performed. Thus, a 3D finite element model was generated from a CT scan, representative of the microstructure and with a similar volume fraction. Effective elastic properties were calc... Read more

Revisiting the lacquer peels method with pyroclastic deposits: sediment plates, a precise, fine scale imaging method and powerful outreach tool

Revisiting the lacquer peels method with pyroclastic deposits: sediment plates, a precise, fine scale imaging method and powerful outreach tool

Sediment plates (a type of lacquer peels) represent a sampling method whereby a thin plate of undisturbed sediments is obtained directly from the outcrop. A low-viscosity, hardening epoxy resin is applied to a freshly exposed cross-section of an unconsolidated deposit and impregnates a surface layer of the cross-section via capillary forces before solidifying. Upon hardening, a solid plate (0.5–5 cm thick and up to 2 m in length) of the sedimentary formation can be recovered and transported... Read more

In situ characterization of immiscible three-phase flow at the pore scale for a water-wet carbonate rock

In situ characterization of immiscible three-phase flow at the pore scale for a water-wet carbonate rock

X-ray micro-tomography is used to image the pore-scale configurations of fluid in a rock saturated with three phases – brine, oil and gas – mimicking a subsurface reservoir, at high pressure and temperature. We determine pore occupancy during a displacement sequence that involves waterflooding, gas injection and water re-injection. In the water-wet sample considered, brine occupied the smallest pores, gas the biggest, while oil occupied pores of intermediate size and is displaced ... 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...

Metal-Organic Framework Crystal-Glass Composites

Metal-Organic Framework Crystal-Glass Composites

The majority of research into metal-organic frameworks (MOFs) focuses on their crystalline nature. However, in recent research the vitrification of a number of MOFs has been revealed. We propose that the solid-liquid phase transitions involved in MOF-glass formation can provide unique opportunities for the creation of a new class of functional, stable and porous composite materials. Described herein is the design, synthesis, and characterisation of novel metal-organic framework (MOF) crystal-... Read more

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...

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

Air bubbles in calcium caseinate fibrous material enhances anisotropy

Air bubbles in calcium caseinate fibrous material enhances anisotropy

Dense calcium caseinate dispersions can be transformed into hierarchically fibrous structures by shear deformation. This transformation can be attributed to the intrinsic properties of calcium caseinate. Depending on the dispersion preparation method, a certain amount of air gets entrapped in the sheared protein matrix. Although anisotropy is obtained in the absence of entrapped air, the fibrous appearance and mechanical anisotropy of the calcium caseinate materials are more pronounced with... Read more
