Abstract
Purpose
The purpose of this paper is to show that the droplet impact phenomenon is important for the advancement of industrial technologies in many fields such as spray cooling and ink jet printing. Droplet bouncing on the nonwetting surfaces is a special phenomenon in the impact process which has attracted lots of attention.
Design/methodology/approach
In this work, the authors fabricated two kinds of representative nonwetting surfaces including superhydrophobic surfaces (SHS) and a slippery liquid-infused porous surface (SLIPS) with advanced UV laser processing.
Findings
The droplet bouncing behavior on the two kinds of nonwetting surfaces were compared in the experiments. The results indicate that the increasing Weber number enlarges the maximum droplet spreading diameter and raises the droplet bounce height but has no effect on contact time.
Originality/value
In addition, the authors find that the topological SHS and SLIPS with the laser-processed microwedge groove array produce asymmetric droplet bouncing with opposite offset direction. Microdroplets can be continuously transported without any additional driving force on such a topological SLIPS. The promising method for manipulating droplets has potential applications for the droplet-based microfluidic platforms.

Abstract
Purpose
This paper aims to investigate whether executive compensation and internal control can prevent overseas compliance risks through the mediating influence of multinational corporation (MNC) legitimacy and the moderating role of institutional distance.
Design/methodology/approach
Based on a law and economics perspective and the “bad apple,” the “red barrel” and the “bad cellar” theory of business misconduct, this paper constructs a systematic framework of “compliance motivation MNC legitimacy overseas compliance risk prevention” from the individual, organizational and systematic levels and uses data of Chinese MNCs for empirical analysis.
Findings
Empirical data from Chinese MNCs show that overseas compliance risks are comprehensively affected by the factors of the individual, organizational and systematic levels. Higher executive compensation and internal control will reduce MNCs’ overseas compliance risks through MNC legitimacy acquisition; institutional distance hinders the positive effect of internal control on MNC legitimacy and therefore aggravates overseas compliance risks.
Practical implications
This paper contributes to the understanding of the overseas law-abiding and offence behavior of MNCs from a law and economics perspective and offers valuable insights on how to prevent the ever-increasing overseas compliance risks.
Originality/value
Although the literature has analyzed the factors of compliance behavior, they are not interrelated, let alone integrated in a systematic risk prevention framework. This paper applies a law and economic analysis framework to the study of the overseas compliance risks for the first time.
