Patient Dose Optimisation of Abdominopelvic Protocols During X‐Ray Imaging
Journal of Medical Radiation Sciences, EarlyView.This study evaluates organ doses in abdominopelvic radiography for both erect and supine positions, addressing dose optimisation concerns in Ghana. Using CalDose X and thermoluminescence dosimeters, organ doses and image quality were analysed, revealing significant dose reductions with optimised exposure parameters (70 kVp, 10 mAs, 110 cm FDD).

Interfacial Energy and Composition Controlled Self‐Stratification in Polyurethane Coatings
Macromolecular Materials and Engineering, EarlyView.This study elucidates self‐stratification in polyurethane coatings driven by interfacial energies and composition‐dependent phase separation. Using XPS, SIMS, and Raman analyses, we reveal rapid formation of hydrophobic and hydrophilic layers and substrate‐dependent interfacial structures.

Influence of EDTA Coverage Density on Optical Fiber Sensor for Heavy Metal Ion Detection
Nano Select, EarlyView.This study investigates the influence of chelating agent coverage on the performance of optical fiber sensors for heavy metal ion detection. Ethylenediaminetetraacetic acid (EDTA) was employed to functionalize single‐mode 28 optical fibers (SMF‐28), and the influence of surface coverage uniformity on zinc ion sensing performance was investigated ...
