    Nano-SiO2 and PVA Fiber Synergistically Strengthened Concrete to Optimize the Antifreeze, Antipermeability, and Anticorrosion Performance of Roads by Li Tang

    Published 2022-01-01
    “…After the test piece is immersed in water to reach a saturated state, we check the appearance size of the test piece, wipe the surface of the test piece clean with a rag, weigh the unfreeze-thaw test piece, then measure the ultrasonic wave speed of the test piece with a nondestructive testing instrument, and do good record. After every 25 freeze-thaw cycles, we measure the mass and relative dynamic elastic modulus of each group of specimens, make corresponding records, then put them into the freeze-thaw box, and add clean water as the freeze-thaw medium to continue the test. …”

    Evaluation of the Effect of Nanosilver and Bismuth oxide on the Radiopacity of a Novel Hydraulic Calcium Silicate-based Endodontic Sealer: An In vitro Study by Teena Sheethal Dsouza, Aditya Shetty, Kelvin Peter Pais, Meenakumari Chikkanna, Fahad Hamoud Almutairi, Yazeed Abdulaziz Alharbi, J. Suresh Babu, C. Swarnalatha, Abhishek Singh Nayyar

    Published 2024-12-01
    “…Materials and Methods: The structural characteristics of the novel cement material (Nano CS) were observed using energy-dispersive X-ray analysis under a Zeiss Gemini 500 Field Emission Scanning Electron Microscope, while radiopacity of the test material (Nano CS) was assessed with the help of an aluminum (Al) step‐wedge using a nondestructive testing method following ISO guidelines. The optical density of the test material (Nano CS) was tested with the specimens of mineral trioxide aggregate (MTA) as the standard cement material along with the specimens of enamel and dentin that were 1 mm thick, and Al of appropriate thickness with the desired and equivalent radiopacity. …”
