Specific heat of calcium

As seen here, you wouldn't be able to determine the identity of a calcium unknown thru specific heat in the same manner done for less reactive metals. My CHE 113/111 students need to recognize this...

Chemical Flame Tests

Recall that each element has a characteristic atomic emission spectrum, this is a nice graphic related to this concept!

For my students, it PAY$ to be concerned about getting the structure correct!

To all my current and former students, especially those entering Orgo 1 this fall...pay close attention to get the structure right...I'm certain the folks at PSU are wishing they had!

Heat of Fusion - Heat of Vaporization

Sulfur hexafluoride LUMO

I find this to be deliciously fun!

From the Just Like Cooking blog (http://justlikecooking.blogspot.com/2014/04/science-blackout-poetry.html)...

I'm reasonably certain that is the Carbonic anhydrase (enzyme) ribbon structure above CO2, obviously it is NOT carbon dioxide!

:)

STEM Discovery Day at CU

Taught two groups of 7th graders about proteins, see some photos of their work! Lots of fun!

Coagulating casein with vinegar and filtering from milk!

Main group only Periodic table using Legos

The blue pieces represent valence electrons, you can see metals (green), metalloids (red), and nonmetals (white) AND this version shows the building up of each principal energy level!

ACS webinar AND 2 seminars upcoming that would be good for CHE class extra credit!

There is another segment on the A-Z of Drug discovery tomorrow (March 27):

Dr. Beth Richter, Eli Lilly, Friday, March 28 @ 3pm in AD-15

Amanda Fuller, KAS executive director, Friday, April 4 @ 3pm in AD-15

Afforestation event at TGKY in Lebanon, March 23, 2014

Had a lot of fun, plenty of folks from the community in Central KY taking part in an environmental stewardship project...see some photos!

Isoniazid, a tuberculosis drug

Below is the structure of Isoniazid, or Isonicotinic acid hydrazide. It finds use in treatments for tuberculosis. This compound, which incorporates a carbonyl functionality as part of the hydrazide (similar in structure to a secondary amide) and the nitrogenous heterocycle pyridine.

Chemical Equilibrium and the Haber process for Ammonia synthesis

This link provides a nice connection of equilibrium and Le Chatelier's principle and the Haber process, mentioned in my CHE 112 class today!

http://www.chem1.com/acad/webtext/chemeq/Eq-02.html#SEC4

Those curious should read about Haber in the book "From Stars to Stalagmites" by Paul Braterman, link to Amazon site here: http://www.amazon.com/From-Stars-To-Stalagmites-Everything/dp/9814324973

ACS Molecule of the Week (February 17-21, 2014)

Clothianidin is a neonicotinoid. Neonicotinoids are a class of insecticides that are chemically similar to nicotine, which has been used as a pesticide since the late 1700s.

http://www.acs.org/content/acs/en/molecule-of-the-week/archive/clothianidin.html

Here is a link regarding its synthesis:

Why is mercury a liquid?

Relates very much to our discussion of IM in CHE 112.

International REU programs

Study abroad, research...why not both?

Check into it here...but hurry, the deadline is January 31!
