stonework components to develop an appropriate coating for it. They have found that the building was mainly magnesian limestone, which oxides and sulfur pollutants in the rain can harm. The rain can cause small cracks and crevices in parts of the stone, weakening it and can let the building eventually break down and washed away. Wilson and her team formulated a coating from oleic acid, the main ingredient of olive oil, and a compound called perfluoro-declytrimethoxysilane, C10H4F17Si(OMe)3. This coating was tested on a sample from the Minister, exposing it to sulfuric acid. Results of the testings have shown promising results. More testings will take place in multiple parts of the building so that they are exposed to the atmosphere directly. Since air pollution have caused serious salt weather and decay on the buildings, Wilson and her team’s findings at Cardiff University adds an alternative option to conserving ancient buildings. Although the chemistry of atmospheric pollutants has been detrimental to ancient buildings, scientists are able to use chemistry to protect them. Wilson and her team used hydrophobic ingredients to guard the ancient stones from the harmful rain, which consisted of polar molecules and water. I chose this article because in class, we learned that “like dissolves like” in terms of polarity. This article is an example of a use of a solution of non-polar molecules to repel polar molecules. To solve a complicated problem such as protecting ancient stones from acidic rain and atmospheric pollutants, the simple molecule structures must be considered first.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
