Science and the Scientist: How we communicate complex ideas, from comic books to journal articles (Fall 2023; Veronica Berns)

Clear and concise communication is highly valued in many STEM fields. Whether conveying the technical details of an experiment for a colleague or translating the impact of a study for the public, scientists need to discuss complex ideas with different audiences. This course analyzes the goals of scientific writing by examining texts that represent different levels of communication, including how to use auditory podcasts and the visual language of comic books for conveying complex scientific ideas.

What's So Special About Nanomaterials? (Fall 2023; Katherine Gesmundo)

Over the past 20 years, nanotechnology has been a booming area of research in chemistry, biology, physics, engineering, and medicine. Modern techniques have allowed scientists to better study small materials, and the nanotech we read about in science fiction novels can now become real products found in our world. In this seminar, we will discuss what is so special about the size range of 1-100 nm (the nanoscale) and why particles of this size have a such a unique niche in nature and technology. We will explore the properties of these materials and why quantum mechanical effects allow for this scale to be so important. Discussions of medicines, electronics, catalysts, additives, and imaging agents that include nanoparticles will allow us to explore the wide range of current directions of nanotechnology. As we look to future applications, we will debate the implications of these materials on the environment, human health, and safety. Regulatory bodies in the United States and around the globe have discussed the ethical and social impact of nanomaterials, and we will investigate their role is assuring the nanomaterials we use leave a positive impact on the world.

This course covers basic concepts in Inorganic Chemistry. It is designed to introduce students in key subjects which are used over and over again in chemistry and uses inorganic chemistry systems to illustrate the concepts. The course covers the donor-acceptor concept, hard-soft acids-bases, advanced concepts of basicity and acidity and acid-base view of salvation phenomena. The course also delves into introductory solid state chemistry including unit cells and the structure of simple solids, structure types and electronic structure and Band Theory (with the aim of understanding properties). 

A certain fraction of the time is also devoted to descriptive chemistry which utilizes the concepts learned in the first part of the course and the focus is generally on main group chemistry. This includes the chemistry of hydrogen and the chemistry of the elements of Group 12, 13, 14, 15 and 16.

The aim of this course is to provide graduate students with an intuitive understanding of quantum mechanics in preparation of advanced quantum chemistry courses and their research. Basic topics will be covered such as the Schrödinger equation, the Heisenberg uncertainty principle, operators, and commutation relations, and simple quantum systems will be solved using analytical techniques. A basic understanding of algebra and differential equations is required. Throughout this course, an emphasis will be put on how the quantum mechanical concepts are related to one another, as well as to everyday classical phenomena.

The goal of Responsible Conduct of Research (RCR) training is for researchers to perform the most ethical research possible. RCR training is critical to prepare undergraduate students, graduate students, and postdoctoral researchers for ethical challenges that may arise when conducting research. RCR is mandatory for all Department of Chemistry researchers. Undergraduate researchers are required to complete the on-line course only.
