What is the difference in research culture between a University of X and a X University of Technology?
Historically speaking, it's possible there would have been differences between what the universities researched or were built to research and thus were given different names. However, research directions and capabilities change over time and I don't think it's possible to draw such distinctions based on name alone these days. Research "quality" or "standards" can also be somewhat subjective, and will definitely vary from country to country.
