“…The application of game theory to analyze the strategic choices of a firm in EIS literature has gained attention in recent times (Wu et al , 2017; Qian et al , 2018; Miaoui and Boudriga, 2019; Xu and Zhuang, 2019; Feng et al , 2020; Li and Xu, 2020; Peng et al , 2020; Wu et al , 2020; Zhai et al , 2020). Laszka et al (2015) provide a detailed literature review of existing research on strategic games under a full-information setting.…”

“…We observe that broadly two forms of probability functions are adopted in the extant game-theoretic EIS literature: BPF first proposed by Gordon and Loeb (2002), modified by Cavusoglu et al (2008) and used in a multitude of cybersecurity investment problems (Huang et al , 2008; Kim and Kim, 2016; Young et al , 2016; Ezhei and Ladani, 2017; Qian et al , 2017; Wu et al , 2017; Ezhei and Ladani, 2018; Qian et al , 2018; Miaoui and Boudriga, 2019; Dou et al , 2020; Feng et al , 2020; Gordon et al , 2020; Li and Xu, 2020; Wu et al , 2020).

Purpose This paper aims to examine optimal decisions for information security investments for a firm in a fuzzy environment. Under both sequential and simultaneous attack scenarios, optimal investment of firm, optimal efforts of attackers and their economic utilities are determined. Design/methodology/approach Throughout the analysis, a single firm and two attackers for a “firm as a leader” in a sequential game setting and “firm versus attackers” in a simultaneous game setting are considered. While the firm makes investments to secure its information assets, the attackers spend their efforts to launch breaches. Findings It is observed that the firm needs to invest more when it announces its security investment decisions ahead of attacks. In contrast, the firm can invest relatively less when all agents are unaware of each other’s choices in advance. Further, the study reveals that attackers need to exert higher effort when no agent enjoys the privilege of being a leader. Research limitations/implications In a novel approach, inherent system vulnerability of the firm, financial benefit of attackers from the breach and monetary loss suffered by the firm are considered, as fuzzy variables in the well-recognized Gordon – Loeb breach function, with the help of fuzzy expectation operator. Practical implications This study reports that the optimal breach effort exerted by each attacker is proportional to its obtained economic benefit for both sequential and simultaneous attack scenarios. A set of numerical experiments and sensitivity analyzes complement the analytical modeling. Originality/value In a novel approach, inherent system vulnerability of the firm, financial benefit of attackers from the breach and monetary loss suffered by the firm are considered, as fuzzy variables in the well-recognized Gordon – Loeb breach function, with the help of fuzzy expectation operator.

“…MoS 2 quantum dots (QDs) with ultra-small sizes and many more active sites are beneficial for HER. Based on this, many methods including hydrothermal method [8][9][10], microwaveassisted synthesis [11], sono-chemical exfoliation [12] are developed to prepare MoS 2 QDs. However, MoS 2 QDs with ultra-small sizes are easy to aggregate and has poor conductivity, which seriously affects their electrocatalytic performance toward HER.…”

Ultra-small MoS 2 quantum dots (QDs) with an average size of 2.48 nm coated on Au nanoparticles with a core-satellite structure (Au/MoS 2 QDs) are successfully prepared by a self-assembly strategy through the strong bonding between Au and S. Benefited from the unique structure, the Au/MoS 2 QDs hybrid exhibits outstanding electrocatalytic performance toward hydrogen evolution reaction (HER). The Au/MoS 2 QDs hybrid needs overpotentials of 112, 146, and 206 mV to approach current densities of 10, 20, and 50 mA•cm −2 in 0.5 mol•L −1 H 2 SO 4 (pH = 0.3), respectively. And a low Tafel slope (83 mV•dec −1) is obtained. The catalyst also displays satisfactory stability and durability, indicating a negligible current density loss after 20 h of electrolysis. The high hydrogen generation activities and stability are attributed to the great number of active sites, high conductivity and synergistic effects between gold nanoparticles (Au NPs) and MoS 2 QDs. Last but not least, this strategy opens up a favorable way to combine MoS 2 QDs with other metals.
