A solid mixture of zinc salts (0.55 g zinc acetate) and 0.41 g 2-MIM was dissolved in 50 mL methanol. The molar ratio of 2-MIM/Zn2+ in this mother solution was 2:1. The mixed solution was treated by ultrasonication to dissolve all the chemicals. Preparation of ZIF-8 membra...
However, the new grains on the basal plane were associated with the nucleation on prior deformed grains which indicates the transformation from CDRX to the discontinuous dynamic recrystallization (DDRX) in this plane. At lower processing temperatures (less than 250 °C), a mixture of equiaxed ...
A high rate of formation of a biphase boride coating (80–90μ) was attained in the first hour of boriding steel 40Kh in a mixture of 80% B+16% Na 2 B 4 O 7 +4% KBF 4 . The boride coatings obtained in this mixture with holding for 2–6 h are even and dense with no ...

The quenching and partitioning (Q&P) method addressed in this paper has been specifically developed for tailoring excellent mechanical properties of conventional low-carbon steels by generating microstructures that contain a mixture of martensite and retained austenite1,2,3,4,5,6,7. Q&P processing ...
In the 1970s, BASF and Porsche co-developed plastic (polyamide-based) intake manifolds, which broke through the bottleneck of industrial development. The intake manifold, located between the vehicle's throttle valve and the engine's intake valve, distributes the air and fuel mixture to each cyli...
The invention relates to a mixture to be introduced into the slag located on a metal melt in iron and steel metallurgy, to the use of such a mixture and to a process for conditioning a slag located on a metal melt in a metallurgical vessel, for example in a converter, in an electric ...
