Abstract
Purpose The purpose of this study is to determine the effect of board effectiveness (BE) on financial performance and operational risk (OR) disclosure and the interaction effect of a bank's Sharia Supervisory Board quality (SSB) with religious and ethical principles. Design/methodology/approach The data were collected from the annual financial reports of 25 Islamic banks (IBs) in the Gulf Cooperation Council countries over 2008-2017. The OR disclosure, the SSB quality and BE were measured using self-developed indices. The Tawhidi string relation methodology was used to establish the circular causal model. The moderating effect of the SSB quality on the performance, OR disclosure and board structure relationship was examined using the hierarchical regression analysis. Findings The main finding of this study is related to the positive moderating effect of SSB quality on the relationship between performance, OR disclosure and BE. This result seems to indicate that at a high level of SSB quality, even when the performance increase the IBs engage in complying with OR disclosure to inform the stakeholders on the real situation of the bank. Practical implications The finding of this research would be of great support to stakeholders and policymakers to make more pressure on IBs to improve the quality of their SSB structure and show more compliance with the governance recommendations. As an extension to this research, further study can examine other Islamic governance mechanisms such as Shari?ah-compliant banks. Originality/value The present study provides a new addition to the prior literature by investigating the relationship between performance, BE, OR disclosure and the interaction effect of SSB quality. From an Islamic ethical, this research can also contribute to the growing discussion on SSB quality and performance.

Abstract
Li-ion batteries have revolutionized the portable electronics industry and empowered the electric vehicle (EV) revolution. Unfortunately, traditional Li-ion chemistry is approaching its physicochemical limit. The demand for higher density (longer range), high power (fast charging), and safer EVs has recently created a resurgence of interest in solid state batteries (SSB). Historically, research has focused on improving the ionic conductivity of solid electrolytes, yet ceramic solids now deliver sufficient ionic conductivity. The barriers lie within the interfaces between the electrolyte and the two electrodes, in the mechanical properties throughout the device, and in processing scalability. In 2017 the Faraday Institution, the UK's independent institute for electrochemical energy storage research, launched the SOLBAT (solid-state lithium metal anode battery) project, aimed at understanding the fundamental science underpinning the problems of SSBs, and recognising that the paucity of such understanding is the major barrier to progress. The purpose of this Roadmap is to present an overview of the fundamental challenges impeding the development of SSBs, the advances in science and technology necessary to understand the underlying science, and the multidisciplinary approach being taken by SOLBAT researchers in facing these challenges. It is our hope that this Roadmap will guide academia, industry, and funding agencies towards the further development of these batteries in the future.
