This phenomenological study explores the mentoring needs of 13 Black and Latinx engineering postdoctoral scholars with an adaptation of the ideal mentoring model used as the conceptual framework. A documented four-stage process of phenomenological data analysis was employed to examine the interview data: epoché, horizontalization, imaginative variation, and synthesis. The phenomenon’s essence is Black and Latinx engineering postdoctoral scholars have primary and secondary mentoring needs pertaining to their immediate career acquisition of a position in the professoriate. Primary mentoring needs include expanding their professional networks and support in crafting competitive application packages and coaching on work-life balance. Secondary needs consist of enhancing and promoting their technical skills, as well as acquiring political guidance on matters of race/ethnicity in academia.more » « less

Abstract Batteries and supercapacitors have emerged as promising candidates for next-generation energy storage technologies. The rapid development of new two-dimensional (2D) electrode materials indicates a new era in energy storage devices. MXenes are a new type of layered 2D transition metal carbides, nitrides, or carbonitrides that have drawn much attention because of their excellent electrical conductivity, electrochemical and hydrophilic properties, large surface area, and attractive topological structure. This review focuses on various synthesis methods to prepare vanadium carbide MXenes with and without etchants like hydrofluoric acid, lithium fluoride, and hydrochloric acid to remove the ‘A’ layers of the MAX phase. The goal is to demonstrate the utilization of a less toxic etching method to achieve MXenes of comparable properties to those prepared by traditional methods. The influence of intercalation on the effect of high interlayer spacing between the MXene layers and the performance of MXenes as supercapacitor and battery electrodes is also addressed in this review. Lastly, the gaps in the current knowledge for vanadium carbide MXenes in synthesis, scalability, and utilization in more energy storage devices were discussed.more » « less

This phenomenological study (Moustakas, 1994) explores the mentoring needs of 11 engineering postdoctoral scholars of color with an adaptation of the ideal mentoring model (Zambrana et al., 2015) used as the conceptual framework. A critical theory lens (Morrow & Brown, 1994) is applied to Moustakas’ (1994) four-stage process of phenomenological data analysis to examine the interview data: epoché, horizontalization, imaginative variation, and synthesis. The essence of the phenomenon is engineering postdoctoral scholars of color have primary and secondary mentoring needs pertaining to their immediate career acquisition of a tenure-track faculty position. Primary mentoring needs include expanding professional networks for the tenure-track faculty job search and receiving guidance on work-life balance and enhancing technical skills. Secondary needs consist of refining research directions and research expertise promotion, as well as acquiring political guidance on matters of race/ethnicity in academia. These findings reveal the importance of higher education institutions and postdoctoral supervisors assuming greater responsibility for ensuring postdoctoral scholars receive the mentorship and career support they desire, which may require a systematic change in the postdoctoral training environment.more » « less
