Pre-Inscribed Laser Surface Pattering for Increased Joining Strength in Laser Fusion Bonding of CFRP and Zinc-Coated Steel

In this study, we present improved fusion-bonding strength results between carbon fiber-reinforced polyetheretherketone (CFR-PEEK) and zinc-coated steel through the introduction of pre-inscribed laser surface patterns.Optimized laser welding parameters, including laser power, focal position, pitch, number of passes, and clamping pressure, are prese

The importance of cylinder passivation for preparation and long-term stability of multicomponent monoterpene primary reference materials

Monoterpenes play an important role in atmospheric chemistry due to their large anthropogenic and biogenic emission sources and high chemical reactivity.As a consequence, measurements are required to assess how changes in emissions of monoterpenes impact air quality.Accurate and comparable measurements of monoterpenes in indoor and outdoor environm
