This template is adapted from the previous template I wrote in 2017:
University of Nottingham Thesis and Dissertation Template
The current one includes more sample scripts in Chapter 4 Main Chapter, demonstrating the use of figures, tables, lists (for Research Questions and Hypotheses, etc.), equations, and PDF appendix in the Appendices chapter.
This one is specifically shaped for a PhD thesis submission.
Please double check with your faculty's thesis submission guideline.
