Mechanical Behaviour and Microstructure of Aluminum-Steel Sheets Joined by FSSW [PDF]

Texture, Stress, and Microstructure, 2008
At the prospect of a lightening of the automobile structures, welded spots have been realized on a stacking of two sheets (a 6008 aluminum alloy on steel) Friction Stir Spot welding (FSSW). Different process parameters have been tested, but only the influence of the dwell time will be described in the present paper.

18O enrichment of sucrose and photosynthetic and nonphotosynthetic leaf water in a C3 grass—atmospheric drivers and physiological relations

Plant, Cell &Environment, Volume 46, Issue 9, Page 2628-2648, September 2023., 2023
Abstract The 18O enrichment (Δ18O) of leaf water affects the Δ18O of photosynthetic products such as sucrose, generating an isotopic archive of plant function and past climate. However, uncertainty remains as to whether leaf water compartmentation between photosynthetic and nonphotosynthetic tissue affects the relationship between Δ18O of bulk leaf ...
