Chemistry Central blog We are pleased to announce that Professor Liang-Nian He, a Professor of Chemistry at the State Key Laboratory of Elemento-Organic Chemistry, Nankai University, China has joined the Editorial Board for Sustainable Chemical Processes. His research interests include: green synthetic chemistry; synthesis and application of task-specific ionic liquids; catalysis in green solvents such as ionic liquids, PEG and water; CO2 chemistry; biomass conversion, particularly chemical transformations of CO2 into fuels, chemicals and materials; and CO2 capture and utilization. Associate Professor Michael Oelgemöller from James Cook University, Australia also joins us on the Editorial Board. His research activities include synthetic organic photochemistry, solar photochemistry, microflow photochemistry, the development of new photochemical synthesis tools and photochemical water treatment. He is a leading expert in …
My window is too large and wider than my screen. How to I resize it back? Something was downloaded to my computer while I was away this week. (My husband probably thought it was ok.) Now when I open an email thru Outlook it’s huge – it goes way off the screen to the right. I don’t know how to resize this or fix this.
What is a synchrotron? A synchrotron is an extremely powerful source of X-rays. These are produced by highly energetic electrons moving in a large circle in the synchrotron. The entire world of synchrotron science depends on one physical phenomenon: When a moving electron changes direction, it emits energy. When the electron is moving fast enough, the emitted energy is at X-ray wavelength.
Molecule of the Month Welcome to the Molecule of the Month page! This is one of the longest running chemistry webpages on the internet (started in January 1996). Each month since then a new molecule has been added to the list on this page. UNC Chemistry Fundamentals An Interactive Educational Exercise Because of special formatting tags needed to display exponents, this site is best viewed with Netscape 3.0 or higher. If needed, use the link under Useful Materials to download Netscape About the Chemistry Fundamentals Course This exercise is designed for anyone who wants an introduction or review of the fundamentals of chemistry that will be used in freshman level chemistry classes. This interactive course was used for the first time during the summer of 1997.
Covalent radius The covalent radius, rcov, is a measure of the size of an atom that forms part of one covalent bond. It is measured either in picometres (pm) or ångströms (Å), with 1 Å = 100 pm. In principle, the sum of the two covalent radii should equal the covalent bond length between two atoms, R(AB) = r(A) + r(B). theconversation Science is like high-performance racing: today’s Formula One machine is all too soon the jalopy of tomorrow. The Australian Synchrotron, opened in 2007 and located in Melbourne, is currently at the F1 end of the spectrum. Needless to say, its 120 staff and thousands of active researchers would like to keep it that way. Which raises a pertinent and obvious question: what does it actually do? Technically speaking, a synchrotron is a large machine that accelerates electrons to almost the speed of light. As those electrons are deflected through magnetic fields they create extremely bright light, meaning a synchrotron is also a “light source”.
Site-offline The Department of Chemistry at McGill University provides a comprehensive teaching and research environment in the chemical sciences. With 35 faculty and 4 research-active emeritus faculty members, the Department presently hosts over 150 graduate students and 60 PDFs/RAs. The Department is emerging from a period of unprecedented renewal of its laboratory infrastructure, with $50M investment yielding state-of-the-art research and teaching laboratories. Honours, Majors, Minor, and Liberal BSc programs in Chemistry are offered, leading to ca. 40 p.a. students graduating with a Chemistry degree. There are currently over 200 students enrolled in our undergraduate programs. BSc graduates from the Majors and Honours go on to graduate studies, positions in industry and teaching as well as further studies in professional programs in medicine, law, business administration, and public health.
