In the era of the internet of things, there exists a pressing need for technologies that meet the stringent demands of wearable, self-powered, and seamlessly integrated devices. Current approaches to developing MXene-based electrochemical sensors involve either rigid or opaque components, limiting their use in niche applications. This study investigates the potential of pristine Ti 3 C 2 T x electrodes for flexible and transparent electrochemical sensing, achieved through an exploration of how material characteristics (flake size, flake orientation, film geometry, and uniformity) impact the electrochemical activity of the outer sphere redox probe ruthenium hexamine using cyclic voltammetry. The optimized electrode made of stacked large Ti 3 C 2 T x flakes demonstrated excellent reproducibility and resistance to bending conditions, suggesting their use for reliable, robust, and flexible sensors. Reducing electrode thickness resulted in an amplified faradaic-to-capacitance signal, which is advantageous for this application. This led to the deposition of transparent thin Ti 3 C 2 T x films, which maintained their best performance up to 73% transparency. These findings underscore its promise for high-performance, tailored sensors, marking a significant stride in advancing MXene utilization in next-generation electrochemical sensing technologies. The results encourage the analytical electrochemistry field to take advantage of the unique properties that pristine Ti 3 C 2 T x electrodes can provide in sensing through more parametric studies.

Tuneable infrared properties, such as transparency and emissivity, are highly desirable for a range of applications, including thermal windows and emissive cooling. Here, we demonstrate the use of carbon nanotube networks spray-deposited onto an ionic liquid-infused membrane to fabricate devices with electrochromic modulation in the mid-infrared spectrum, facilitating control of emissivity and apparent temperature. Such modulation is enabled by intraband transitions in unsorted single-walled carbon nanotube networks, allowing the use of scalable nanotube inks for printed devices. These devices are optimized by varying film thickness and sheet resistance, demonstrating the emissivity modulation (from ∼0.5 to ∼0.2). These devices and the understanding thereof open the door to selection criteria for infrared electrochromic materials based on the relationship between band structure, electrochemistry, and optothermal properties to enable the development of solution-processable large-area coatings for widespread thermal management applications.

This article is one in a series in which contributing authors discuss how the United Nations (UN) Sustainable Development Goals (SDGs) are linked to everyday clinical issues; national public health emergencies; and other nursing issues, such as leadership, shared governance, and advocacy. The 2030 Agenda for Sustainable Development, a 15-year plan of action to achieve the goals, was unanimously adopted by all UN member states in September 2015 and took effect on January 1, 2016. The Agenda consists of 17 SDGs addressing social, economic, and environmental determinants of health and 169 associated targets focused on five themes: people, planet, peace, prosperity, and partnership. The SDGs build on the work of the UN Millennium Development Goals, which were in effect from 2000 to 2015. The current article discusses the International Council of Nurses Global Nursing Leadership Institute and its integration of the SDGs into a global leadership and policy development program., (Copyright © 2021 Wolters Kluwer Health, Inc.

Background: In 2020, the SARS-CoV-2 pandemic forced the redesign of the International Council of Nurses' (ICN) Global Nursing Leadership Institute (GNLI) that heretofore had included an intensive, week-long residential experience in Geneva, Switzerland., Aim: This paper describes the development, implementation, challenges and preliminary outcomes of an approach that regionalized GNLI and delivered it online, while preserving some cross-regional connections among participants., Results: A virtual approach to a global policy leadership programme cannot replace the richness of an intensive, concentrated residential one, but the redesign of GNLI has given ICN, its member national nursing associations and individual nurse leaders previously unexplored opportunities for networking and collaboration aligned with the six WHO regions, and for cross-region networking and discussions of global issues., Conclusion and Implications for Nursing And/or Health Policy: The SARS-CoV-2 pandemic has highlighted the need for nursing leadership in policy and practice. A virtual approach to leadership development can increase the reach of programmes that seek to build nursing's capacity to advance health-promoting policies in workplaces, organizations and nations., (© 2021 International Council of Nurses.)
