Introduction to Solid-State Chemistry

Why This Matters

“Why This Matters” is a brief portion of each lecture focusing on how the topic covered relates to important innovations (and sometimes unexpected consequences) in science and in life, demonstrating real world applications, and suggesting creative directions for research.

Chemistry is connected to the questions surrounding us. For example:

  • why the Haber-Bosch Process helped world population to soar,

  • how painting with electrons led to color television, how defects cause the same jewel to have different colors,

  • just how efficient batteries really are,

  • how automobiles became safer through tempered glass as well as less polluting through the catalytic converter,

  • how graphene can help us obtain clean drinking water,

  • why tires can’t be recycled,

  • how nanotechnology requires an understanding of chemistry,

  • why chlorofluorocarbons stopped being used in refrigeration, and

  • what is happening to the oceans as they absorb excess carbon.

For more information about the origin and reason for the creation of the Why This Matters segments, see this description in the Instructor Insights.
