Ziliang Chen, Hongyuan Yang, Zhenhui Kang, Matthias Driess, more

Advanced Materials > 34 > 18 > n/a - n/a

Transition metals, in particular noble metals, are the most common species in metal‐mediated water electrolysis because they serve as highly active catalytic sites. In many cases, the presence of nontransition metals, that is, s‐, p‐, and f‐block metals with high natural abundance in the earth‐crust in the catalytic material is indispensable to boost efficiency and durability in water electrolysis...

Modulation of the secondary Bjerknes force in multi-bubble systems

Haiyan Chen, Ziliang Chen, Yi Li

Ultrasonics Sonochemistry > 2020 > 61 > C

The behaviours of insonated bubble clusters are regulated by the secondary Bjerknes force between bubble pairs. While the force has been investigated extensively for two-bubble systems, the modulation of the force by nearby bubbles remains unclear. This problem is investigated in this paper by theoretical analyses and numerical simulations of a three bubble system. For weak oscillations, the third...

Concurrency and Computation: Practice and Experience > 31 > 20 > n/a - n/a

Similarity join on high‐dimensional data is a primitive operation. It is used to find all data pairs that with distance no more than ϵ from the given data set according to a specific distance measure. As the data set scale and dimension increase, computation cost increases vastly. Hadoop and Spark have become the popular platforms for big‐data analysis. Because Spark has native advantages in iterative...
