Department of Chemistry- University at Albany – SUNY

Posted on by

The Department of Chemistry at the University at Albany, SUNY, has never been stronger. In the area of undergraduate education, we have witnessed a steady increase in our major and overall enrollment in record numbers. On the graduate side, there are now close to 70 graduate students who are conducting innovative research in a wide variety of scientific subjects. Today, Chemistry is one of the best funded units on campus. Our faculty members publish in high-impact, peer-reviewed journals and receive the most competitive research funding from National Science Foundation (NSF), National Institutes of Health (NIH), the Department of Defense (DOD) and the National Institute of Justice (NIJ), etc. As a result, exciting research opportunities abound for our graduate students and undergraduates alike. And, we are still growing.

Last year we recruited two new faculty members in the area of organic and biophysical chemistry from the Massachusetts Institute of Technology (MIT) and Harvard Medical School. This year, we are recruiting two more faculty members in the area of forensic chemistry, analytical chemistry and toxicology to strengthen the Forensic Chemistry division, a newly minted area of growth. As you peruse our department website, I am confident that you will recognize we are a fast-growing, vibrant department in a world-class university. Our curricula, faculty research interests, and interdepartmental and multidisciplinary programs each demonstrate our long-standing commitment to the quality of education at both the undergraduate and graduate level, and to the pursuit of rigorous study and creative research anchored in the chemical science.

Atomic structure, atomic numbers, atomic mass, moles, ions (eventually), compounds (eventually)

We are now going to delve into the heart of chemistry. We learn ways of representing chemical molecules and how molecules react. To do this, we'll even think about "how many" of a molecule we have using a quantity called a "mole".

Bohr model, absorption, emission spectrum, quantum numbers, electron configurations

Classification of elements, atomic radii, ionic radii, ionization energy, electron affinity

The Nobel Prize in Chemistry 2015 – Press Release

Posted on by

7 October 2015

The Royal Swedish Academy of Sciences has decided to award the Nobel Prize in Chemistry for 2015 to

Tomas Lindahl Francis Crick Institute and Clare Hall Laboratory, Hertfordshire, UK

Paul Modrich Howard Hughes Medical Institute and Duke University School of Medicine, Durham, NC, USA

and

Aziz Sancar University of North Carolina, Chapel Hill, NC, USA

for mechanistic studies of DNA repair"

The Nobel Prize in Chemistry 2015 is awarded to Tomas Lindahl, Paul Modrich and Aziz Sancar for having mapped, at a molecular level, how cells repair damaged DNA and safeguard the genetic information. Their work has provided fundamental knowledge of how a living cell functions and is, for instance, used for the development of new cancer treatments.

Each day our DNA is damaged by UV radiation, free radicals and other carcinogenic substances, but even without such external attacks, a DNA molecule is inherently unstable. Thousands of spontaneous changes to a cells genome occur on a daily basis. Furthermore, defects can also arise when DNA is copied during cell division, a process that occurs several million times every day in the human body.

The reason our genetic material does not disintegrate into complete chemical chaos is that a host of molecular systems continuously monitor and repair DNA. The Nobel Prize in Chemistry 2015 awards three pioneering scientists who have mapped how several of these repair systems function at a detailed molecular level.

In the early 1970s, scientists believed that DNA was an extremely stable molecule, but Tomas Lindahl demonstrated that DNA decays at a rate that ought to have made the development of life on Earth impossible. This insight led him to discover a molecular machinery, base excision repair, which constantly counteracts the collapse of our DNA.

Aziz Sancar has mapped nucleotide excision repair, the mechanism that cells use to repair UV damage to DNA. People born with defects in this repair system will develop skin cancer if they are exposed to sunlight. The cell also utilises nucleotide excision repair to correct defects caused by mutagenic substances, among other things.

Paul Modrich has demonstrated how the cell corrects errors that occur when DNA is replicated during cell division. This mechanism, mismatch repair, reduces the error frequency during DNA replication by about a thousandfold. Congenital defects in mismatch repair are known, for example, to cause a hereditary variant of colon cancer.

The Nobel Laureates in Chemistry 2015 have provided fundamental insights into how cells function, knowledge that can be used, for instance, in the development of new cancer treatments.
