Chemistry mainly deals with chemical and physical changes associated with any substances. All chemical changes can be represented with the help of chemical equations which are symbolic representations of chemical reactions. The physical changes are mainly associated with the change in state of matter. Chemistry also provides necessary information related to the physical state of matter with their inter-conversion into each other. Chemistry explains the atomic structure of any substance with the help of atomic models and theories. These concepts help us to understand some common concepts which we can observe in our surroundings such as cooking, burning, melting of ice etc. These are either chemical changes or physical changes. But how can you identify them? Definitely chemistry can help you with this. You can take help of online tutor to understand the basic concepts of chemistry such as atomic models, atomic theories, thermodynamic, Thermochemistry, chemical kinetics etc. All these topics are connected with each other and easy to understand if you are aware about the basics of chemistry. Chemistry is the study of matter and the ways in which matter changes. Matter is anything that takes up space and has mass. Chemistry therefore takes in all that we see … Continue reading →

Deoxyribonucleic acid (DNA) is a nucleic acid that contains the genetic instructions for the development and function of living organisms. All living things contain DNA, with the exception of some viruses with RNA genomes. The main role of DNA in the cell is the long term storage of information. It is often compared to a blueprint, since it contains the instructions to construct other components of the cell, such as proteins and RNA molecules. The DNA segments that carry genetic information are called genes, but other DNA sequences have structural purposes, or are involved in regulating the expression of genetic information. DNA is a long polymer of simple units called nucleotides, which are held together by a backbone made of sugars and phosphate groups. This backbone carries four types of molecules called bases and it is the sequence of these four bases that encodes information. The major function of DNA is to encode the sequence of amino acid residues in proteins, using the genetic code. To read the genetic code, cells make a copy of a stretch of DNA in the nucleic acid RNA. These RNA copies can then be used to direct protein synthesis, but they can also be … Continue reading →

The Central Science. Chemistry is the link that connects problems in the fundamental nature of matter to the most complex problems in the processes of life. Members of our department bring chemistry to life as cutting-edge researchers and as teachers for students across the university. Undergraduates majoring in chemistry can go on to several professional fields, including medicine and graduate study, and are also in high demand in fields like secondary education. Our commitment to teaching is also reflected in our desire to build a community environment and provide every opportunity of success for our undergraduates. Toward that end, we have initiated a Chemistry Learning Community for our first year and transfer students. Our Ph.D. program has a history of cutting edge and often interdisciplinary research that will teach you to be an independent scientist, ready for a career in industry or academia. Our goal is to help you learn the most modern research techniques and to think creatively about solutions to major scientific problems. Undergraduate Graduate The Department of Chemistry is pleased to announce new faculty joining us in 2015. Robbyn K. Anand Robbyn K. Anand will join the chemistry faculty in August 2015 as an Assistant Professor. She … Continue reading →

New Fundraising Campaign Underway We, the junior faculty of the Department of Chemistry, have launched a fundraising effort specifically aimed at supporting the Chemistry graduate students. We see great promise in our graduate students and, in order to improve recruitment and retention, their merits must be better supported. As such, we have each donated to one of two existing endowed funds aimed at increasing merit-based funding opportunities for graduate student summer research. Front: Prof. Sam Pazicni and Prof. Meg Greenslade Back: Prof. Erik Berda, Prof. Leila Deravi and Prof. Gonghu Li These funds include: the Clarence L. and Helen M. Garland Grant Fellowship fund and Mary Zoukis Papastavros 60 Chemistry fund. Our ultimate goal is an increased ability to provide adequate and competitive compensation to all of our graduate students. We hope you can contribute as well!
