Superheated steam acts as both a heat source and a drying medium. The study sought to predict the evolution of the moisture transport behaviour of the corn kernel at various axial distances at varying instantaneous time. The equations describing the drying phases were solved using numerical solutions with the Eulerian technique in ANSYS software. Cone geometry was used to simulate the corn kernel with initial moisture content at 20% w.b. Steam conditions were similar to what is encountered in industry, with temperatures ranging (from 120–200°C) at 1.5 m s−1 velocity. ANOVA was used to determine if there was difference between the conditions. The temporal change in moisture from the apex to the periphery varied at superheated steam temperatures 120, 160 and 200°C. At 10, 100 and 200 s the drying rate and effective moisture diffusivity of corn kernel from the centre towards the periphery differed. Post‐hoc analysis with Bonferroni adjustment revealed that moisture content (w.b.%) differed between 10 and 100 s, 10 and 200 s and 100 and 200 s. The mean difference was attributed to the drying being in the falling drying phase at 200 s and initial condensation at 10 s. Thus, at high superheated steam temperatures, dry zones can be seen as the axial distance from the apex increases toward the periphery.

Bimodal Ultrasound and X-ray Bioimaging Properties of Particulate Calcium Fluoride Biomaterial

Ultrasound (US) and X-ray imaging are diagnostic methods that are commonly used to image internal body structures. Several organic and inorganic imaging contrast agents are commercially available. However, their synthesis and purification remain challenging, in addition to posing safety issues. Here, we report on the promise of widespread, safe, and easy-to-produce particulate calcium fluoride (part-CaF2) as a bimodal US and X-ray contrast agent. Pure and highly crystalline part-CaF2 is obtained using a cheap commercial product. Scanning electron microscopy (SEM) depicts the morphology of these particles, while energy-dispersive X-ray spectroscopy (EDS) confirms their chemical composition. Diffuse reflectance ultraviolet-visible spectroscopy highlights their insulating behavior. The X-ray diffraction (XRD) pattern reveals that part-CaF2 crystallizes in the face-centered cubic cell lattice. Further analyses regarding peak broadening are performed using the Scherrer and Williamson–Hall (W-H) methods, which pinpoint the small crystallite size and the presence of lattice strain. X-ray photoelectron spectroscopy (XPS) solely exhibits specific peaks related to CaF2, confirming the absence of any contamination. Additionally, in vitro cytotoxicity and in vivo maximum tolerated dose (MTD) tests prove the biocompatibility of part-CaF2. Finally, the results of the US and X-ray imaging tests strongly signal that part-CaF2 could be exploited in bimodal bioimaging applications. These findings may shed a new light on calcium fluoride and the opportunities it offers in biomedical engineering.
