Resonance‐induced restoration of rock permeability degraded by heavy components of crude oil

Deep Underground Science and Engineering, EarlyView.
Resonance‐induced changes occur in filtration properties of sedimentary rocks in crude paraffin oil flow under acoustic vibrations. Experimental data on (a) pressure drop; (b) permeability; (c) pressure at the rock inlet; and (d) pressure at the rock outlet are presented.

Imaging spontaneous imbibition in full Darcy‐scale samples at pore‐scale resolution by fast X‐ray tomography [PDF]

, 2019
Spontaneous imbibition is a process occurring in a porous medium which describes wetting phase replacing nonwetting phase spontaneously due to capillary forces.

Mineral‐targeted alkaline phosphatase improves bone graft‐mediated alveolar bone defect healing in mice

Journal of Periodontology, EarlyView.
Abstract Background Alveolar bone loss challenges tooth retention and implant placement. Freeze‐dried bone allograft (FDBA) is widely used for alveolar ridge preservation but has limitations in resorption rate and healing time. In this proof‐of‐concept study, we tested whether pro‐mineralization enzyme, tissue‐nonspecific alkaline phosphatase (TNAP ...

Analysis by x-ray microtomography of a granular packing undergoing compaction [PDF]

, 2003
Several acquisitions of X-ray microtomography have been performed on a beads packing while it compacts under vertical vibrations. An image analysis allows to study the evolution of the packing structure during its progressive densification. In particular,

Bridging wheat kernel microstructure and flour rheology occurring during wheat germination

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Wheat germination increases α‐amylase activity, leading to significant biochemical and structural changes that influence flour rheological properties. Understanding the correlation between internal kernel structure and flour rheology is essential for predicting processing performance and optimizing the use of germinated wheat in ...

Microfocus X-ray imaging of Brazil nuts for quality control

Semina: Ciências Agrárias, 2015
Non-destructive quality assessment of food prior to processing is desirable in commercial facilities due to its non-invasive nature, for economic reasons and for its safety appeals. Grading Brazil nuts in this way allows for the separation of undesirable

Quantitative characterization of pore structure of several biochars with 3D imaging

, 2017
Pore space characteristics of biochars may vary depending on the used raw material and processing technology. Pore structure has significant effects on the water retention properties of biochar amended soils.
