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.

After a three-year sojourn in Europe, Gibbs spent the rest of his career at Yale, where he was professor of mathematical physics from 1871 until his death. Working in relative isolation, he became the earliest theoretical scientist in the United States to earn an international reputation and was praised by Albert Einstein as "the greatest mind in American history". In 1901 Gibbs received what was then considered the highest honor awarded by the international scientific community, the Copley Medal of the Royal Society of London, "for his contributions to mathematical physics".
Chemical heritage - history by people. The story of chemistry is a human adventure of both mind and action.
From very early times, chemists have sought to expand our understanding of matter, from the atomic to the galactic. Meanwhile, they have contributed to the modern world as we know it, through new materials, medicines, and technologies, as well as environmental problems and solutions. Look for an expanding set of themes under which chemists have pursued their investigations over time. Early Chemistry and Gases › Linus Pauling and The Nature of the Chemical Bond: A Documentary History. Revised and Expanded Utilizing over 2,500 manuscript pages, nearly 100 photographs, and more than four hours of audio and video, this website tells the story of a cornerstone achievement of twentieth century science.
In 1926 Linus Pauling, then a promising young doctoral candidate, set sail for Europe to study quantum mechanics with an eye toward applying this new physics to problems in structural chemistry. Pauling's ensuing program of research would result in a remarkable series of landmark publications that revolutionized the scientific world's conception of how atoms join together to form molecules. In 1939 Pauling's ideas were bundled into a book that was uniformly recognized as an instant classic. Chemistry resources (C2k) Welcome to ChemWeb.

The left column shows MO's which are occupied in the ground state, with the lowest-energy orbital at the top. The white and grey line visible in some MO's is the molecular axis passing through the nuclei. The orbital wave functions are positive in the red regions and negative in the blue. The right column shows virtual MO's which are empty in the ground state, but may be occupied in excited states.
Overview A molecular orbital (MO) can be used to represent the regions in a molecule where an electron occupying that orbital is likely to be found. Formation of molecular orbitals Molecular orbitals arise from allowed interactions between atomic orbitals, which are allowed if the symmetries (determined from group theory) of the atomic orbitals are compatible with each other.

This site contains popular-science style articles describing many aspects of electrochemistry, electroanalytical chemistry, electrochemical engineering, and electrochemical technology, written by international experts in the field. It is crosslinked with the ELECTROCHEMISTRY DICTIONARY for definitions. New articles are added at irregular intervals, and all articles are periodically updated as recent developments occur in the field. ( The Encyclopedia is hosted by the Ernest B.
