Should my supervisor acknowledge me in his recent paper? In my chemistry undergraduate I did a project with my supervisor, I worked on it for around 8 months. Around a year later they published a paper on this same topic, after my project was handed in they asked for more details about certain elements that weren't clear in my final draft and I helped the best I could. 

To be clear, none of my data was published in the paper and the research that was published was leaps and bounds more advanced anything I did. But I feel so they perhaps used my research to rule out certain things that didn't work or need repeating. Do you think my name should be mentioned anywhere in the paper as just an acknowledgement?
What deserves acknowledgment and what does not is vague. It completely depends on the author(s). In my view, what you did definitely deserves at least acknowledgment. Maybe they decided that because they did not use your data, then there is no reason to mention you. Maybe they did not really care about you and what you think, given that this was some time ago.
