This article is focused main problem during and after FSW especially when joining blanks AA2024 embedded with interlayer strip widths AA7075, in microstructure of the welded zone, that will in turn affect its mechanical properties of the welded joints. So, a number of interlock strip widths of AA7075 as 1, 1.5, 2, 2.5 and 3 mm were added bet...... hiện toàn bộ
Betaine-based deep eutectic solvents with diol, acid and amine hydrogen bond donors for carbon dioxide absorptionJournal of Physics: Conference Series - Tập 1295 Số 1 - Trang 012039 - 2019
Kamarza Mulia, Elsa Anisa Krisanti, Nasruddin Nasruddin, Elbert Libriandy
Abstract
Deep eutectic solvents (DESs) are known as alternative green solvents due to their ease of synthesis, availability, biodegradability and negligible volatility. DESs consisted of betaine as the hydrogen bond acceptor with 1,2-propanediol, levulinic acid and methyl diethanolamine (MDEA) as the hydrogen bond donors, were prepared in 1:3 and 1:6...... hiện toàn bộ
