course web site

Students enrolled in CHEM 125 have access to a Moodle course web site, by logging into the Moodle server. If you are a member of the Kenyon community and have a Kenyon network account, you can log into our course homepage using the login key "nano". If you are off the Kenyon network, this site is unavailable directly.

course overview

"Why cannot we write the entire 24 volumes of the Encyclopedia Brittanica on the head of a pin?"

physicist Richard Feynman famously asked.

 

Nanoscience is an emerging field that focuses on the study of materials on the nanometer (billionth of a meter) scale.  Nanoscience encompasses the principles of how to make and measure the properties of nano-scale materials for a wide variety of applications known as “nanotechnology”.  The field is interdisciplinary by nature, combining chemistry, physics, biology and engineering.  Materials Chemistry is the related field of chemistry in the solid state, at the nano-scale or larger, ranging from organic plastics to inorganic semiconductors.

 

In CHEM 125: Nanoscience and Materials Chemistry, we will explore the chemistry behind such topics as: fuel cells, photovoltaic materials for solar panels, carbon nanotubes, quantum dots, glucose and other biomedical sensors, photodynamic therapy for cancer, molecular self assembly, artificial photosynthesis, sensors for explosives and bio-warfare agents, self-cleaning windows, clear sunscreens, gold nanoparticles that cure cancer, light emitting diodes (LEDs), molecular wires, and the curse of the nanobots.  Do novels like Prey by Michael Crichton or movies like Fantastic Voyage accurately represent the nanoworld?  Could nanobots in our bloodstream cure disease, or will they cover the planet in a “grey goo”?  We will also explore some debates about the hope and hype of nanoscience.

 

CHEM 125 is a course designed to explore the principles of chemistry that are essential to nanoscience and materials chemistry.  This course or CHEM 124 (Biophysical and Medicinal Chemistry) are the second semester introductory chemistry options for students who have completed either CHEM 121 or CHEM 122.   CHEM 124 and CHEM 125 have similar requirements and expectations for homework and exams.  Either spring semester course (with lab) is appropriate for continuing your studies in Organic Chemistry next year, and either course satisfies requirements for pre-med or chemistry and biochemistry majors.

 

We recommend students registering for CHEM 125 also register for the accompanying lab course CHEM 126 section 04, if possible.  

 

CHEM 125 will use the textbook Chemical Principles (5th Ed.) by Zumdahl (same as that used in CHEM 122 in the fall semester)
