Chemistry Road Show to Hahnville High!

Chemistry Students and Faculty take the Chemistry Road Show to Hahnville High School

  On Friday, May 13th, 2016 students in the Chemistry club and chemistry faculty spent the day at Hahnville High School in Boutte, Louisiana.   11th grade students in Ms. Grunblatt’s Chemistry I classes learned about some of the exciting things that chemists do.  

  Students participated in hands on activities such as the analysis of vinegar by titration, spectroscopic analysis of atoms and molecules, gas chromatography,  polymer synthesis and making ice cream with liquid nitrogen (yum yum)!  

  Scott Hutchinson, Lauren Luce, Dr. Cortez, Dr. Marlow, Mrs. Wayment. and Dr. Wayment all assisted with the project.

Dr. Cortez teaches about polymers and later on liquid nitrogen ice cream.

Chemistry students present research

Four chemistry students recently presented their research results at the 11th Annual Research Week held on the Nicholls campus from February 29th – March 3rd.

Courtney Beamer, Michael Kramer, Shane Swan and Cyrus PIcou each presented posters on a variety topics, ranging from environmental chemistry to molecular modeling.  

Courtney Beamer showcased her work in developing liquid phase microextraction for the detection of polyaromatic hydrocarbon (PAH) compounds in Bayou Lafourche.  Many of these compounds are carcinogenic and pose a health hazard.

Michael Kramer investigated the presence of inorganic pollutants in Bayou Lafourche using the newly acquired ion chromatogaph.  This instrument is capable of measuring ions and carbohydrates on the order of parts per million or lower.

Shane Swan presented his results of investigations of organic pollutants in Bayou Lafourche.  He used the newly acquired gas chromatograph – mass spectrometer (GC-MS) to identify compounds related to the weathering of oil from oil spills.

Cyrus Picou investigated the use of molecular modeling techniques to develop a simple model that allows the prediction of physical properties of hydrocarbons based on calculated molecular surface areas and volumes.

Chemistry department acquires powerful new instrument

The chemistry faculty are celebrating the installation of a powerful new instrument that will allow researchers to study the chemical structure of molecules. The new 400 MHz NMR Spectrometer will be used to study physical, chemical, and biological properties of matter and has applications in many areas of science.

The molecules under study are placed in a high magnetic field and exposed to pulses of radio waves.  Specific atomic nuclei then absorb and re-emit radio waves at specific frequencies  The frequency emitted depends upon the electronic environment of each atom and allows scientists to know how the atoms are connected together within the molecule.   

The main component of the instrument is a superconducting magnet that is cooled to a bone chilling temperature of 4.2 K (-269 ºC), which is just above the temperature of deep space.

Students in chemistry laboratories will gain valuable hands-on experience with a powerful, high-tech instrument that previously was not available to them.  In addition to use in the teaching labs, the instrument will be used by Nicholls State University faculty and students to study the structures of synthesized molecules, such as biomedical polymers and organic solar cells.  Other research will involve studying the structure of catalysts for the synthesis of stereo-specific antitumor drugs and in the identification of the microbial metabolites of pesticides, petroleum hydrocarbons and explosives in the environment.  The chemistry degree at Nicholls is accredited by the American Chemical Society and opens the door for many careers in industry and teaching, as well as graduate and professional schools.  Acquisition of this special instrument is important for this accreditation.The instrument was purchased with assistance from the Louisiana Board of Regents Support Fund and Nicholls State University.
