Roy A. Periana
Roy A. Periana is a Guyanese-American organometallic chemist. Biography Early life He was born in Georgetown, Guyana in 1957. After moving to the United States after high school, Periana studied and received a B.S. in chemistry at the University of Michigan in 1979. He then worked in industry at the Dow Chemical Company in Midland, Michigan. In 1981, he returned to graduate school at the University of California Berkeley where he received his Ph.D. in 1985 under Robert G. Bergman. His work with Bergman focused on the development of novel rhodium complexes that undergo C-H and C-C bond activation of alkanes. His dissertation was entitled, "Mechanism of Oxidative Addition of Cyclopentadienyl-Rhodium Complexes to Carbon-Hydrogen and Carbon-Carbon Bonds." Career After graduation, Periana joined the Monsanto Company as a research chemist. In 1988, he moved to Silicon Valley and joined Catalytica, Inc. as a Team Leader. Several years later, his group spun off from Cataly ...

Alkanes
In organic chemistry, an alkane, or paraffin (a historical trivial name that also has other meanings), is an acyclic saturated hydrocarbon. In other words, an alkane consists of hydrogen and carbon atoms arranged in a tree structure in which all the carbon–carbon bonds are single. Alkanes have the general chemical formula . The alkanes range in complexity from the simplest case of methane (), where ''n'' = 1 (sometimes called the parent molecule), to arbitrarily large and complex molecules, like pentacontane () or 6-ethyl-2-methyl-5-(1-methylethyl) octane, an isomer of tetradecane (). The International Union of Pure and Applied Chemistry (IUPAC) defines alkanes as "acyclic branched or unbranched hydrocarbons having the general formula , and therefore consisting entirely of hydrogen atoms and saturated carbon atoms". However, some sources use the term to denote ''any'' saturated hydrocarbon, including those that are either monocyclic (i.e. the cycloalkanes) or po ...

Petroleum
Petroleum, also known as crude oil, or simply oil, is a naturally occurring yellowish-black liquid mixture of mainly hydrocarbons, and is found in geological formations. The name ''petroleum'' covers both naturally occurring unprocessed crude oil and petroleum products that consist of refined crude oil. A fossil fuel, petroleum is formed when large quantities of dead organisms, mostly zooplankton and algae, are buried underneath sedimentary rock and subjected to both prolonged heat and pressure. Petroleum is primarily recovered by oil drilling. Drilling is carried out after studies of structural geology, sedimentary basin analysis, and reservoir characterisation. Recent developments in technologies have also led to exploitation of other unconventional reserves such as oil sands and oil shale. Once extracted, oil is refined and separated, most easily by distillation, into innumerable products for direct use or use in manufacturing. Products include fuels such as gasol ...

Greenhouse Gas
A greenhouse gas (GHG or GhG) is a gas that Absorption (electromagnetic radiation), absorbs and Emission (electromagnetic radiation), emits radiant energy within the thermal infrared range, causing the greenhouse effect. The primary greenhouse gases in Atmosphere of Earth, Earth's atmosphere are water vapor (), carbon dioxide (), methane (), nitrous oxide (), and ozone (). Without greenhouse gases, the average temperature of Earth#Surface, Earth's surface would be about , rather than the present average of . The atmospheres of atmosphere of Venus, Venus, atmosphere of Mars, Mars and atmosphere of Titan, Titan also contain greenhouse gases. Human activities since the beginning of the Industrial Revolution (around 1750) have increased the Carbon dioxide in Earth's atmosphere, atmospheric concentration of carbon dioxide by over 50%, from 280 parts per million, ppm in 1750 to 421 ppm in 2022. The last time the atmospheric concentration of carbon dioxide was this high was over 3&nbs ...

History TSRI was founded as the Scripps Metabolic Clinic in 1924 by the philanthropist Ellen Browning Scripps in La Jolla, California. The Scripps Metabolic Clinic eventually evolved into the Scripps Clinic and Research Foundation. In 1991, the Scripps Clinic and the Research Foundation became separate corporations, and the Scripps Research Institute was founded. In 1989, TSRI established a graduate program. A second campus was opened in Jupiter, Florida in 2005. In 2007, TSRI president Richard Lerner hired internationally renowned chemist Roy A. Periana to lead what would become the Scripps Energy & Materials Cen ...
