Tests conducted comparing the effect exposure of Paracetamol to a laser with oven heating a sample to a temperature above its melting point, 169 degrees Celsius showed similarities. This implies that the primary cause of sample damage during Raman spectroscopy is heating. It was found that inserting a piece of glass between the sample and the microscope lens dramatically reduced the ability of the laser to damage samples. Computer models indicate that rotating a sample at 8 rotations per minute could be an effective method of limiting sample damage, and is a potential alternative to active cooling if this becomes financially and logistically viable in industry. Active sample cooling was investigated, but results proved inconclusive. This is a key area for any future research on the topic.

In this journal, I will discuss modern day environmental exploitation as it relates to native americans. In my research, I found no shortage of opposition to the dangers of natural resource extraction on tribal lands. While tribes remain sovereign nations, the overarching authority and loopholes of federal and state governments force many indigenous people to remain vulnerable to the violences of capitalism. Against all odds, native individuals and organizations throughout the country, and globe, meet these offenses with fervent opposition. Here, I will explore the tactics and victories of Indigenous North Americans.
