- Title: "Environmental Forensics: The Growing Use of Forensic Techniques in Investigating Environmental Crimes"
- Abstract: Forensic investigative techniques are increasingly being applied to the investigation of environmental crimes. These applications vary widely. For example, they include: chemical fingerprinting for the attribution of liability in chemical or petroleum spills; DNA fingerprinting, ballistics, and other investigations of illegal hunting of wildlife, especially when violations of international trade agreements or the Endangered Species Act are concerned; and epidemiological investigations of disease outbreak when a source of a pathogen may be identified. This seminar will provide an overview of environmental forensic methods and will discuss cases involving these investigations as an introduction to the field.

- Title: "Turning on Chemical Reactions"
- Abstract: Turning on a chemical reaction provides a means to probe the mechanism of the reaction provided the time required to “turn on” the reaction is short in comparison to the subsequent steps leading to the chemical change. This seminar focuses on the “pump-probe” technique to study the dynamics of electron transfer and acid-base reactions. A molecule is rapidly “pumped up” in energy, and the chemistry of this energy-rich molecule with a second molecule is probed by monitoring the changes in the molecule’s absorption and/or emission spectrum as a function of time.

- Title: "The ATE Grant and Its Impact on the QCC Science Student"
- Abstract: The recently awarded ATE grant will offer QCC science students an opportunity to work in a professional environment. Paid internships in institutions such as the Food and Drug Administration (FDA) and the Division of Environmental Protection (DEP) will provide the experience a student needs before entering the workforce.
- Dr. Jun H. Shin (QCC, CUNY)

- Title: "Ansa-Effect in Permethylmetallocene Chemistry"
- Abstract: “Ansa” means “handle” in Latin and is used to describe a bridge between functional groups. When two cyclopentadienyl (Cp) groups are connected by one or more atoms (e.g. B, C, Si, P), the compound is called an ansa-bridged ligand, and a metal complex coordinated by the ansa-bridged ligand is called an ansa-bridged metallocene (ACp2M). The influence of ansa bridges on the chemistry of metallocene complexes will be discussed and compared to non-ansa bridged metallocene complexes.
- Prof. Peter Diaczuk (John Jay College of Criminal Justice)

- Title: "An Introduction to the Field of Forensic Science"
- Abstract: Forensic science has received increasing attention in recent years due to the advent of "Crime Scene Investigation" shows on TV. Yet the reality and myth created in these shows often clash. True forensic science is based on the analysis of biological, chemical, physical evidence in an objective and repeatable fashion. This presentation will provide an overview of the field and its applications.

- Title: "Bottom-Up Nanoconstruction with Metallic Nanoparticles and Biomolecules"
- Abstract: Future energy and national security capabilities will depend upon the successful implementation and integration of state of the art nanomaterials into everyday devices. Metallic nanoparticles in the size range of 1-20 nm offer many unique electronic, optic, catalytic, and sensory properties which are highly influenced by their respective size, their organization on surfaces or in solution, and on their surface chemical makeup. However, the ability to harness these properties for applications depends on our ability to utilize self-assembly approaches. This presentation describes some of these phenomena and focuses on our recent work related to the self-assembly of nanoparticles with DNA. This approach allows for the combination and exploration of both nanotechnology and biotechnology for future sensors, electronics, and advanced biodiagnostics.
