The vibration theory of smell proposes that a molecule's smell character is due to its vibrational frequency in the infrared range. This controversial theory is an alternative to the more widely accepted docking theory of olfaction (formerly termed the shape theory of olfaction), which proposes that a molecule's smell character is due to a range of weak non-covalent interactions between its ...
An olfactometer is an instrument used to detect and measure odor dilution. Olfactometers are used in conjunction with human subjects in laboratory settings, most often in market research, to quantify and qualify human olfaction. [1] Olfactometers are used to gauge the odor detection threshold of substances. To measure intensity, olfactometers ...
Researcher sampling the volatile organic compounds of a historic book using solid phase microextraction at the Heritage Science Lab in University College London Institute for Sustainable Heritage. Olfactory heritage science is an emerging field of research, focused on the scientific techniques to analyse, document and preserve odours and the ...
Her work examines with how language and emotion can affect odor perception and her laboratory has empirically demonstrated the first instance of olfactory illusions created by words alone. [ 9 ] [ 10 ] Herz also studies how we perceive food and how food-based emotions influence us.
The DeGennaro Lab seeks to determine the odors and olfactory receptors that contribute to host detection in mosquitoes, analyze nectar-seeking behavior and examine vector ecology. [3] DeGennaro also intends to establish a model for coral symbiosis and chemosensation using the upside-down jellyfish, Cassiopea xamachana , in order to study new ...
The odor detection threshold is the lowest concentration of a certain odor compound that is perceivable by the human sense of smell. The threshold of a chemical compound is determined in part by its shape, polarity, partial charges, and molecular mass. The olfactory mechanisms responsible for a compound's different detection threshold is not ...
Aromachology is a relatively new science that explores positive feelings induced by odors far from any holistic or healing process. The term covers both natural and synthetic scents. The term aromachology is sometimes mistaken by companies with several other terms such as "essential oils" or "aromatherapy" as marketing phrases.
