Effect of Postweld Heat Treatment on Laser‐Welded Duplex Stainless Steel: Crystallographic Patterns and Fatigue Behavior

steel research international, EarlyView.
Laser welding of duplex stainless steel disrupts phase balance, promotes nitride precipitation, and reduces fatigue resistance. Postweld heat treatment restores austenite and dissolves nitrides, but the resulting crystallography and phase morphology still impair fatigue performance.

Ecotoxicological Evaluation of Organic Sunscreens Used Worldwide, Alone and in Mixture, on Terrestrial Plants

Environmental Toxicology, EarlyView.
ABSTRACT The environmental hazards of sunscreens are discussed worldwide. However, there are few ecotoxicological studies on these compounds alone for edaphic organisms, and none for their mixtures. Avobenzone (1 and 10 ng/L), octocrylene (10 and 100 μg/L), and oxybenzone (2 and 20 μg/L), alone and in binary combinations (between the lowest and the ...
