Laser powder bed fusion (LPBF) additive manufacturing of 2XXX series Al alloys could be used for low volume specialist aerospace components, however, such exhibit hot cracking susceptibility that can lead to component failure. In this study, we show two approaches suppress the formation cracks by controlling solidification behaviour using: (1) TiB2 additions; and (2) optimisation LPBF process parameters. Using high-speed synchrotron X-ray radiography, monitored Al-2139 in situ, with without...
Although a great variety of strategies to suppress Li dendrite have been proposed for lithium metal batteries (LMBs), deeper understanding the factors playing crucial role during extended electrochemical cycling is often lacking. Herein, morphological reversibility Li-based anode next-generation under three prevalent strategies, i.e., use Li–Al alloys, polymer coating, and anodic aluminum oxide (AAO) membrane attachment, has sophisticatedly investigated by nondestructive visualization. The...
Lithium sulfur (Li–S) batteries have great potential as a successor to Li-ion batteries, but their commercialization has been complicated by multitude of issues stemming from complex multiphase chemistry. In situ X-ray tomography investigations enable direct observations be made about battery, providing unprecedented insight into the microstructural evolution cathode and shedding light on reaction kinetics phase. Here, for first time, morphology was visualized in 3D function state charge at...
Capillary-driven ink infiltration through a porous powder bed in three-dimensional (3D) binder jet printing (inkjet onto bed) controls the resolution and as-printed "green" strength of resulting object. However, full understanding factors controlling kinetics remains incomplete.

A static drop-on-demand inkjet printer was to...
To understand fracture behaviour in battery materials, X-ray computed tomography (X-ray CT) has become the primary technique for non-destructive particle analysis. Cracking causes performance decline polycrystalline NMC811 by exposing new surfaces parasitic electrolyte reactions and disconnecting active material from electrode matrix. First cycle crack formation been documented, but definitive electrochemically induced is challenging to assess due complex sample preparation high-resolution...
Molluscan brains are composed of morphologically consistent and functionally interrogable neurons, offering rich opportunities for understanding how neural circuits drive behavior. Nonetheless, detailed component-level CNS maps often lacking, total neuron numbers unknown, organizational principles remain poorly defined, limiting a full systematic characterization circuit operation. Here, we establish an accessible, generalizable approach, harnessing synchrotron X-ray tomography, to rapidly...
Anion exchange membrane water electrolysers are held back by the low durability of ionomer in and catalyst layers. Studying degradation these systems is challenging because main mechanisms, which result detachment, thinning loss cationic functionality, have opposing effects on cell potential; electrochemical measurements alone therefore insufficient for elucidating underlying causes. To address this, a bespoke miniature-electrolyser-cell was developed X-ray microtomography imaging electrode...

Grating-based X-ray and neutron interferometry tomography using phase-stepping methods generates large data sets. An improved algorithm is presented for solving the parameters to calculate transmissions, differential phase contrast, dark-field images.

All of motions are motorized; hence, it is much easier and quicker to switch between different modes operation. A novel aspect this new instrument its designed portability. While primarily used 1-BM, could potentially deployed other APS...
Swelling of shale in response to interaction with water is an important consideration within subsurface energy systems. In the case waste disposal, swelling can provide barriers around and enhance sealing ability rocks. For gas exploration purpose, however, may cause wellbore instability. Therefore, a careful study critical for related applications. Here, effects were imaged at nanoscale using advanced synchrotron Transmission X-ray Microscopy (TXM) imaging technique first time, spatial...
We present a reflection based coherent diffraction imaging method which can be used to reconstruct non periodic surface image from amplitude measured in geometry. Using He-Ne laser, we demonstrated that reconstructed solely the reflected intensity without relying on any prior knowledge of sample object or support. The phase exit wave is particularly interesting since it obtain quantitative information depth profile change during process. believe this work will broaden application areas...
Transverse coherence of the x-ray beam from a bending magnet source was studied along multiple directions using 2-D π/2 phase grating by measuring interferogram visibilities at different distances behind grating. These measurements suggest that preferred orientation checkerboard is diagonal square blocks, where interferograms have higher visibility and are not sensitive to deviation duty cycle period. observations verified thorough wavefront propagation simulations. The accuracy measured...
Dental caries is a widespread disease that proceeds by damaging superficial tooth enamel heterogeneous dissolution. Conventional histology identifies different zones within carious lesions their optical appearance, but fails to quantify the underlying nanoscale structural changes as function of specific location, impeding better understanding demineralisation process. We employ detailed collocative analysis using imaging modalities, resolutions and fields view. Focused ion beam-scanning...
Oleofoams are a novel, versatile, and biocompatible soft material that finds application in drug, cosmetic or nutraceuticals delivery.

Paleoclimatic and paleoceanographic studies routinely rely on the usage of foraminiferal calcite through faunal, morphometric physico-chemical proxies. The application such proxies presupposes extraction cleaning these biomineralized components from ocean sediments in most efficient way, a process which is often labor intensive time consuming. In this respect, study we performed systematic experiment for planktonic specimen using different chemical treatments evaluated resulting data Late...
