Make it snappy! The use of compressed sensing to reconstruct multidimensional NMR spectra enables significant reductions in recording time. Thus, 3D HNCA (blue) and HN(CO)CA (green) sufficient quality for rapid protein-backbone assignment were reconstructed from only 16 % the fully sampled data. generality method its robustness noise should make more broadly applicable, example, solid-state spectroscopy. Detailed facts importance specialist readers are published as ”Supporting Information”....
Recent advances in additive manufacturing technology have enabled rapid and inexpensive prototyping of designs to explore shape effects across a range engineering applications. In this work, we measure the heat transfer performance exchangers based on triply periodic minimal surfaces (TPMS). The results showed that sheet gyroid TPMS design produced high rate moderate pressure drop. was further investigated determine its over porosities ranging from 40% 85%, hydraulic diameters 2 10 mm, wall...
In this paper, we apply electron tomography (ET) to the study of three-dimensional (3D) morphology iron oxide nanoparticles (NPs) with reactive concave surfaces. The ability determine quantitatively volume and shape NP concavity is essential for understanding key-lock mechanism responsible destabilization gold nanocrystals within concavity. We show that quantitative ET enhanced greatly by application compressed sensing (CS) techniques tomographic reconstruction. High-fidelity tomograms using...
This paper investigates the spatial resolution of computational fluid dynamics–discrete element method (CFD-DEM) simulations a bubbling fluidized bed for seven different void fraction schemes. Fluid grids with cell sizes 3.5, 1.6, and 1.3 particle diameters were compared. The velocity maps from all schemes in good qualitative agreement experimental data collected using magnetic resonance imaging (MRI). Refining grid improved quantitative due to more accurate representation flow near gas...

Ultrafast magnetic resonance imaging, employing spiral reciprocal space sampling and compressed sensing image reconstruction, is used to acquire velocity maps of the liquid phase in gas-liquid multiphase flows. Velocity were acquired at a rate 188 frames per second. The method enables quantitative characterization wake dynamics single bubbles bubble swarms. To illustrate this, we use new technique demonstrate role vorticity driving secondary motions, governing structure turbulence
Electrical capacitance tomography (ECT) is well established for 2D imaging of multiphase flow. Increasingly, ECT now being used to image in 3D. In this paper we examine the challenges 3D reconstruction using simulations a 24 electrode (4 planes 6 electrodes each) sensor. particular, demonstrate that changes sensor can be as much an order magnitude less than and condition number 106. We show with dominated by contributions from most widely separated electrodes. If these pairs are eliminated...
Electrical capacitance tomography (ECT) provides a means for non-invasively imaging multiphase flows, such as those in fluidised beds. Traditionally ECT images are reconstructed using the assumption that distribution of permittivity varies smoothly throughout sensor region. However, many applications there step changes permittivity, example, between bubble and particulate phases bed, smoothness is flawed. In this article Total Variation Iterative Soft Thresholding (TV-IST) algorithm used to...
Benchtop NMR analysis combined with model-based fitting protocols can detect commercial honey adulteration down to 5 wt%.
Additive manufacturing (3D printing) is enabling novel porous structures such as triply periodic minimal surfaces (TPMS) that may help improve the efficiency of various applications in chemical engineering. In this work, a range Schwarz–Diamond TPMS were examined experimentally terms printability and pressure drop. X-ray computed tomography scans used to show shape was accurately printed, however systematic reduction porosity observed compared with each designed structure. The drop through...
The flexibility, affordability and ease of use benchtop 1H NMR spectroscopy makes it potentially very interesting for assessing the quality wine types monitoring fermentation process. However, low spectral resolution complexity mixtures hinder direct quantification important parameters and, thus, prevent its widespread as an analytical tool in wineries. We show here that these problems can be solved using model-based data processing. In a first step, accuracy new approach was evaluated by...
