Emma Schymanski (née Craven) is an Australian chemist known for her work identifying unknown organic compounds, particularly pollutants, and is an advocate for open science. She is currently a Professor of Cheminformatics at the University of Luxembourg .
Forensic chemistry is the application of chemistry and its subfield, forensic toxicology, in a legal setting. A forensic chemist can assist in the identification of unknown materials found at a crime scene. [1] Specialists in this field have a wide array of methods and instruments to help identify unknown substances.
GC–MS is used for the analysis of unknown organic compound mixtures. One critical use of this technology is the use of GC–MS to determine the composition of bio-oils processed from raw biomass. [29] GC–MS is also utilized in the identification of continuous phase component in a smart material, magnetorheological (MR) fluid. [30]
In organic chemistry, the bromine test is a qualitative test for the presence of unsaturation (carbon-to-carbon double or triple bonds), phenols and anilines. An unknown sample is treated with a small amount of elemental bromine in an organic solvent, being as dichloromethane or carbon tetrachloride. Presence of unsaturation and/or phenol or ...
The identification of unknown small molecules is considered a critical bottleneck in metabolomics, natural product research, and related fields, given that widely over 90% of all small molecules remain unknown. [32] [33] Commonly, analyses were based on targeted approaches that are limited to the rediscovery of known molecules.
For that, a specific task in science was chosen: help organic chemists in identifying unknown organic molecules, by analyzing their mass spectra and using knowledge of chemistry. [1] It was done at Stanford University by Edward Feigenbaum , Bruce G. Buchanan , [ 2 ] Joshua Lederberg , and Carl Djerassi , along with a team of highly creative ...
It is commonly used for the identification of organic compounds from electron ionization mass spectrometry. [3] [4] Organic chemists obtain mass spectra of chemical compounds as part of structure elucidation and the analysis is part of many organic chemistry curricula.
This is a list of unsolved problems in chemistry. Problems in chemistry are considered unsolved when an expert in the field considers it unsolved or when several experts in the field disagree about a solution to a problem.
