Single-atom catalysis is a powerful and attractive technique with exceptional performance, drastic cost reduction and notable catalytic activity and selectivity. In single-atom catalysis, supported single-atom catalysts contain isolated individual atoms dispersed on, and/or coordinated with, surface atoms of appropriate supports, which not only maximize the atomic efficiency of metals, but also provide an alternative strategy to tune the activity and selectivity of catalytic reactions. This review will highlight the attributes of single-atom catalysis and summarize the most recent advancements in single-atom catalysts with a focus on the design of highly active and stable single atoms. In addition, new research directions and future trends will also be discussed.

Strategic communication (StratCom) is established as one of the key functions and interests of contemporary organisations and governments. The usefulness and importance of strategic communication becomes even more essential when the organisation is defence and security-focused or involved in crisis management. The objective of this study was to assess the strategic communication practices, and inherent challenges of communicating Common Security and Defence Policy (CSDP) and present relevant reflections. A documentary analysis of the relevant EU websites and social media pages of 16 CSDP missions and operations was conducted. This was supplemented with eight key-informant interviews with Press and Public Information Officers (PPIOs) of CSDP and EU strategists. The research demonstrated that most CSDP missions and operations are present on most social media platforms but they often garner very small number of likes, comments, shares, replies or interactions from their targeted audiences. Features of an echo-chamber are also observed. The study also found that public affairs (information) and public diplomacy were the two main forms of strategic communication that the CSDP utilises. CSDP’s strategic communication also tends to take a one-way StratCom process. The challenges faced in terms of StratCom by CSDP are not uniform; they are contextual ranging from resource, translation to mismatch of expectations. The major challenge, however, emanates from the structural problems of CSDP or the EU itself that are beyond the European External Action Service (EEAS) or the relevant Press and Public Information Offices (PPIOs). The study recommendations include quicker EU level political and policy compromise on CSDP, training and resource improvements for StratCom, ‘storytelling and use of real people’, highlighting gender, rights and local ownership, increasing the link with the international media and regular and appropriate self-appraisals.
