Using grape seed extract to reduce erosive potential of drinks
Abstract The aim of this study was to verify whether supplementation of grape seed extract (GSE) to different erosive beverages reduces their erosive potential on dentine in vitro. One‐hundred dentine specimens were randomly assigned to 5 groups (n = 20/group): control‐deionized water, 1%‐citric acid, Red Bull, Coca‐Cola, and Powerade.

ABSTRACT The present study proposes a combined approach of infrared thermography and 3D XFEM numerical models for crack process investigation in mechanical components such as gears. Over the years, fatigue crack analysis based on energy dissipations in the form of heat generated during fatigue tests has been widely reported, although mainly limited to ...

Key Points Higher laser repetition rate, fluence and larger spot size increase signal intensity. Higher laser repetition rate produces overlaps in aerosolised particles, improving signal stability and precision. For Sr‐rich materials, moderate spot diameter (≤ 60 μm), 3 J cm‐2 fluence and ≥ 12 Hz repetition rate are recommended.
