Jeanette G. Grasselli
Jeanette Grasselli Brown (born Jeanette Gecsy; August 4, 1928) is an American analytical chemist and spectroscopist who is known for her work with Standard Oil of Ohio (now BP America) as an industrial researcher in the field of spectroscopy. Spectroscopy is a technique used to measure the interaction of electromagnetic radiation with matter. Her areas of expertise encompass fields such as vibrational spectroscopy, combined instrumental techniques, computerized spectroscopy, and environmental spectroscopy. She developed new techniques to solve problems like identifying contaminants in gasoline, analyzing the makeup of new plastics, and analyzing environmental problems such as pollution. During her career, Grasselli Brown has striven to bridge the gap between research and practical applications between industry and academia. She is considered one of the foremost contributors to infrared and Raman spectrometry of the 20th century. Early life Grasselli Brown was born in 1928 to H ...

Analytical Chemistry
Analytical skill, Analytical chemistry studies and uses instruments and methods to Separation process, separate, identify, and Quantification (science), quantify matter. In practice, separation, identification or quantification may constitute the entire analysis or be combined with another method. Separation isolates analytes. Qualitative inorganic analysis, Qualitative analysis identifies analytes, while Quantitative analysis (chemistry), quantitative analysis determines the numerical amount or concentration. Analytical chemistry consists of classical, wet chemistry, wet chemical methods and modern analytical techniques. Classical qualitative methods use separations such as Precipitation (chemistry), precipitation, Extraction (chemistry), extraction, and distillation. Identification may be based on differences in color, odor, melting point, boiling point, solubility, radioactivity or reactivity. Classical quantitative analysis uses mass or volume changes to quantify amount. Ins ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mount Union College
The University of Mount Union is a private liberal arts university in Alliance, Ohio, United States. Founded in 1846, the university was affiliated with the Methodist Church until 2019. It had an enrollment of 2,100 students as of 2023. History Mount Union was founded in 1846 by Orville Nelson Hartshorn as the Select School as "a place where men and women could be educated with equal opportunity, science would parallel the humanities, and there would be no distinction due to race, color, or sex." Only three years after opening, in 1849, it was renamed as the Mount Union Seminary. The school would not be chartered under Ohio state law until June 9, 1856, after which it adopted the name Mount Union College.

United States Department Of Energy
The United States Department of Energy (DOE) is an executive department of the U.S. federal government that oversees U.S. national energy policy and energy production, the research and development of nuclear power, the military's nuclear weapons program, nuclear reactor production for the United States Navy, energy-related research, and energy conservation. The DOE was created in 1977 in the aftermath of the 1973 oil crisis. It sponsors more physical science research than any other U.S. federal agency, the majority of which is conducted through its system of National Laboratories. The DOE also directs research in genomics, with the Human Genome Project originating from a DOE initiative. The department is headed by the secretary of energy, who reports directly to the president of the United States and is a member of the Cabinet.

Infrared Spectrometer
Infrared spectroscopy (IR spectroscopy or vibrational spectroscopy) is the measurement of the interaction of infrared radiation with matter by absorption, emission, or reflection. It is used to study and identify chemical substances or functional groups in solid, liquid, or gaseous forms. It can be used to characterize new materials or identify and verify known and unknown samples. The method or technique of infrared spectroscopy is conducted with an instrument called an infrared spectrometer (or spectrophotometer) which produces an infrared spectrum. An IR spectrum can be visualized in a graph of infrared light absorbance (or transmittance) on the vertical axis vs. frequency, wavenumber or wavelength on the horizontal axis. Typical units of wavenumber used in IR spectra are reciprocal centimeters, with the symbol cm−1. Units of IR wavelength are commonly given in micrometers (formerly called "microns"), symbol μm, which are related to the wavenumber in a reciprocal way. A ...

University Of Pécs
The University of Pécs ( , PTE; ) is one of the largest higher education institutions in Hungary. The history of the university began in the Middle Ages, when in 1367, at the request of Louis I of Hungary, King Louis I the Great, Pope Urban V granted permission to found the institution. This made it the first university in Hungary and the fourth in Central Europe. The official successor of the university is the :hu:Erzsébet Tudományegyetem, Elisabeth University of Bratislava, Pozsony (Bratislava), founded in 1912.
