The paper results page is no longer on the chemical detail page, it is something that you would have to access once you have searched for a structure and have your results. To access the papers, when you are on the results page, you can scroll to a particular structure you are interested in and click on the number of papers, as shown below:
The papers will open in a new paper view where you have the option of viewing substances that have been tagged to a specific paper. To do that, if you click on the tick box, you will be able to extract the chemical structures from these papers, up to 100 papers each time, and view them on the Chemical platform. Furthermore, users can not only find the basic information about the paper on this page but also refine the data set with keywords (title and abstract fields).
