== Chemistry Department Periodic Table of Elements ==

This wiki page will be used as a centralized means of keeping track of the progress made on our periodic table.

=== Instructions for Using the Laser ===

Step 1. Turn on laser by turning on the power strip to the left of the laser. You will be able to tell if it is on. You may want to turn on the emergency exhaust for the adjacent fume hood while the laser is in use.

Step 2. While the laser is initializing, log onto the computer.

Step 3. Click on the RetinaEngrave3D program. Click on the Generation 5 Hobby 20x12" laser.

Step 4. Home the laser by pressing the home button on the laser.

Step 5. Put a piece of wood in the engraving area so that it is laying flat. Use the arrow buttons on the laser to move the guide laser (red dot) to the point that you would like the laser to begin at. Focus the laser for this thickness of material.

Step 6. Open the Element Template Document, located below. Go to the page containing the element that you would like to print, then hit CTRL+P to print.

[[:File:Elements_Template.docx]]

Step 7. Ensure that you select "Full Spectrum Engineering Driver" as your printer and change the print setting to print only the current page.

Step 8. Click on the RetinaEngrave3D program. You should see that your element has loaded. Click on the Vector Cut tab. Click on the box outlining the element and change it to a color that is not black.

Step 9. On the right-hand side, you should see options under "Vector Layers" for two colors: the color of the box and the color of the rest of the element. Change the Number of Passes for the Black Color to 0 and the Speed for the Yellow Color to 15. Leave the remaining settings alone.

Step 10. Still on the right-hand side, you should see an option for "Raster Speed". Change this to 40.

Step 11. Towards the top-middle portion of the screen, you should see an option called Vector Mode. Change this to Raster then Vector.

Step 12. Hit the Start Job button. (This looks like a play button.) The laser should start engraving your wood! Keep an eye on the laser while it is engraving, as there is a potential fire risk whenever we engrave.

Step 13. Enjoy your newly engraved element! If you are finished engraving, turn off the laser. If not, you can repeat the process beginning with step 5.

This is a person walking at a normal pace with shoes on. When you put your foot on the ground, you are applying a force to it while this is happening the ground also applies an equal force onto your foot, in the opposite direction, pushing you forward. Walking involves the connection of surfaces (that is your shoe and the ground) without any relative movement. This is static friction which essentially gives off heat leaving a "ghost" foot print behind. In other terms it takes a certain amount of work (w) and energy (U) to walk that puts off heat (q).

While watching the film "Nova: Absolute Zero" it was interesting to learn about the historical evolution on the idea of cold. Willis Carrier is known for being the head engineer in inventing the first air conditioning machine in 1902 along side several other men. He got the idea while working in a fan warehouse and implemented his idea to help a printing copy keep the ink on the page during a hot Brooklyn day. The air conditioning system he made was more than just cold, it could also heat and keep a constant humidity. Carrier was always ahead of the game and changed from ammonia to using CFC two years before it was required. Now Carrier is using CO2 systems that reduce the green house gas admission.

==Research Times==
Thur 9-12 pm

==Proposed Research Project==
===Examining the Effects of Propolis on Cancer Cell Membranes and Bacterial Cell Membranes===

===General Information===
:Advisor: Audra Sostarecz
:Other research student collaborators: Ben, Kelly, Nichole Musselman, and Izabela Sartori
:Other Research Collaborators: Colorado State University, Prof. Debbie Crans

===Abstract===
Langmuir-Blodgett Monolayers of propolis and phospholipids can be examined for antibacterial and anti-cancerous properties. The Langmuir Monolayer technique allows for the analysis of the organization of amphiphilic molecules at an air-water interface and is, therefore, a useful technique for the formation of model cell membranes. What is propolis? Propolis is a green-yellow to red-brown resinous material collected from various vegetation around the hive and used to cover the walls of the hive, keep out intruders, and keep out harmful pathogens. There are different chemical composition of the propolis based on the vegetation at the geological location. As a result the biological activity of the propolis is related to the plants native to the site of collection (toreti, 2013). Langmuir monolayers of American propolis are found to have a higher degree of order (less fluidity) and to be more stable indicated by a higher surface pressure at low molecular areas when incorporated into a film with phospholipids such as dipalmitoylphosphatidylcholine (DPPC) and dipalmitoylphosphatidylethanolamine (DPPE).
