You are going to perform an online literature search using a few different library databases looking for two different kinds of article. The first database of scientific journals is the from the American Chemical Society (ACS), the second is EBSCO's Academic Search Complete, and the third is Elsevier's Science Direct.
Scientific research articles provide a method for scientists to communicate with other scientists about the results of their research. A standard format is used for these articles, in which the author presents the research in an orderly, logical manner.
A research article is a publication of an original, peer reviewed presentation of an experiment with results and conclusions. Usually the article has the following parts
Here's an example of scientific research article from the International Journal of Quantum Chemistry. It was found in the Ebsco database Academic Search Complete.

A review article surveys and summarizes previously published studies, rather than reporting new facts or analysis. These articles summarize a broader range of other research articles giving a summary of multiple research articles.
Review articles exist to give researchers a broad view of a particular area of research and may include findings from many different labs. They will not usually have a methodology section but they generally have very extensive bibliographies.
Here's an example of scientific review article from the journal Sensors.

What is Supplemental Information?
For scientific publications it’s typically experimental details or additional data that either cannot be included in the main article due to length constraints or is “supplementary” to the necessary information presented in the main paper. It can also be defined as additional details or data that the author thinks could be relevant to the reader but are not essential to include in the main paper. Supporting information may be needed if all the experimental details cannot be included in the main manuscript or if you want to include extra peripheral data that could be useful to the reader of your article.
How to Find Supplemental Information for Articles in Each Database
American Chemical Society
In ASC it's called "Supporting Info" and appears as a link like this:
Academic Search
In Academic Search it's called "Supplementary information" and you can get the link in the PDF itself or in the HTML version in the index to the left.
Or
