Roman Kaiser
Roman Kaiser (born in Kirchberg SG on 15 July 1945) is a Swiss fragrance chemist. Since 1968 he has been working at Givaudan, the world's largest company in the flavour and fragrance industry, where he analyzes and reconstitutes natural scents for use in perfumery using the headspace technology which he pioneered and which as a new concept made significant impact on the analysis of natural products. Career Following his chemistry studies at the Zurich University of Applied Sciences he joined the research center of Givaudan in Dübendorf near Zürich in 1968, and since then has been working as a fragrance chemist in this company. His main research activity centers around the study and the reconstitution of the scents of nature, and the search for as well as the synthesis of new odorants isolated from nature. For this purpose, he has since 1975 applied the headspace technology which leaves the plant and its flowers intact by analyzing the surrounding air with the help of gas chr ...

Organic Synthesis
Organic synthesis is a special branch of chemical synthesis and is concerned with the intentional construction of organic compounds. Organic molecules are often more complex than inorganic compounds, and their synthesis has developed into one of the most important branches of organic chemistry. There are several main areas of research within the general area of organic synthesis: ''total synthesis'', ''semisynthesis'', and ''methodology''. Total synthesis A total synthesis is the complete chemical synthesis of complex organic molecules from simple, commercially available petrochemical or natural precursors. Total synthesis may be accomplished either via a linear or convergent approach. In a ''linear'' synthesis—often adequate for simple structures—several steps are performed one after another until the molecule is complete; the chemical compounds made in each step are called synthetic intermediates. Most often, each step in a synthesis refers to a separate rea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Scentography
Scentography is the technique of creating and storing odor by artificially recreating a smell using chemical and electronic means. DigiScents Inc was among the more recent pioneers of the technology, developing DigiScent (later iSmell) in 1999 as a device that would plug into a computer's USB port and generate scents dependent on the online content being viewed. The company ceased trading in 2011. In 2013, Amy Radcliffe, a Master's student in the Textile Futures department of Central Saint Martins, London introduced a prototype of a desktop device to record aromas. For the project, she drew on headspace technology pioneered in the 1980s by Roman Kaiser to capture smells in the air around certain objects. Called the Madeleine, after the Marcel Proust episode from ''Remembrance of Things Past'', the device is a working prototype of a new kind of camera to record smell. It consists of a funnel to be placed over the object with the scent you wish to capture. This is attached to a p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Patent
A patent is a type of intellectual property that gives its owner the legal right to exclude others from making, using, or selling an invention for a limited period of time in exchange for publishing an enabling disclosure of the invention."A patent is not the grant of a right to make or use or sell. It does not, directly or indirectly, imply any such right. It grants only the right to exclude others. The supposition that a right to make is created by the patent grant is obviously inconsistent with the established distinctions between generic and specific patents, and with the well-known fact that a very considerable portion of the patents granted are in a field covered by a former relatively generic or basic patent, are tributary to such earlier patent, and cannot be practiced unless by license thereunder." – ''Herman v. Youngstown Car Mfg. Co.'', 191 F. 579, 584–85, 112 CCA 185 (6th Cir. 1911) In most countries, patent rights fall under private law and the patent holder mus ...

Academic Journal
An academic journal or scholarly journal is a periodical publication in which scholarship relating to a particular academic discipline is published. Academic journals serve as permanent and transparent forums for the presentation, scrutiny, and discussion of research. They nearly-universally require peer-review or other scrutiny from contemporaries competent and established in their respective fields. Content typically takes the form of articles presenting original research, review articles, or book reviews. The purpose of an academic journal, according to Henry Oldenburg (the first editor of ''Philosophical Transactions of the Royal Society''), is to give researchers a venue to "impart their knowledge to one another, and contribute what they can to the Grand design of improving natural knowledge, and perfecting all Philosophical Arts, and Sciences." The term ''academic journal'' applies to scholarly publications in all fields; this article discusses the aspects common to all ac ...

Tropical Rainforests
Tropical rainforests are rainforests that occur in areas of tropical rainforest climate in which there is no dry season – all months have an average precipitation of at least 60 mm – and may also be referred to as ''lowland equatorial evergreen rainforest''. True rainforests are typically found between 10 degrees north and south of the equator (see map); they are a sub-set of the tropical forest biome that occurs roughly within the 28-degree latitudes (in the equatorial zone between the Tropic of Cancer and Tropic of Capricorn). Within the World Wildlife Fund's biome classification, tropical rainforests are a type of tropical moist broadleaf forest (or tropical wet forest) that also includes the more extensive seasonal tropical forests. Overview Tropical rainforests are characterized by two words: hot and wet. Mean monthly temperatures exceed during all months of the year. Average annual rainfall is no less than and can exceed although it typically lies betw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plants
Plants are predominantly Photosynthesis, photosynthetic eukaryotes of the Kingdom (biology), kingdom Plantae. Historically, the plant kingdom encompassed all living things that were not animals, and included algae and fungi; however, all current definitions of Plantae exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria). By one definition, plants form the clade Viridiplantae (Latin name for "green plants") which is sister of the Glaucophyte, Glaucophyta, and consists of the green algae and Embryophyte, Embryophyta (land plants). The latter includes the flowering plants, conifers and other gymnosperms, ferns and Fern ally, their allies, hornworts, liverworts, and mosses. Most plants are multicellular organisms. Green plants obtain most of their energy from sunlight via photosynthesis by primary chloroplasts that are derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green colo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Philip Kraft
Philip Kraft (born in Rendsburg on March 24, 1969) is a Germans, German organic chemistry, organic chemist. Since 1996 he has been employed by Givaudan, a leading Flavor and Fragrance company, where he designs captive odorants for use in perfumes. He has lectured at the University of Bern, the University of Zurich, and the ETH Zurich. Career Kraft's interest in fragrance chemistry and perfumery was awakened in 1986 by an article on rose oxide analogs, which led to contacts with Haarmann & Reimer (now Symrise), where he was introduced to the world of scents and fragrances. After graduation from high school and military service which involved forensic and analytical chemistry, he studied chemistry from 1989–1994 at the University of Kiel. He obtained his degree while working in Werner Tochtermann's group, then continued his research with this group, producing his PhD thesis on the Organic synthesis, synthesis of macrocyclic musks in 1996. Moving to industry, he joined Givaudan's F ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Honorary Degree
An honorary degree is an academic degree for which a university (or other degree-awarding institution) has waived all of the usual requirements. It is also known by the Latin phrases ''honoris causa'' ("for the sake of the honour") or ''ad honorem '' ("to the honour"). The degree is typically a doctorate or, less commonly, a master's degree, and may be awarded to someone who has no prior connection with the academic institution or no previous postsecondary education. An example of identifying a recipient of this award is as follows: Doctorate in Business Administration (''Hon. Causa''). The degree is often conferred as a way of honouring a distinguished visitor's contributions to a specific field or to society in general. It is sometimes recommended that such degrees be listed in one's curriculum vitae (CV) as an award, and not in the education section. With regard to the use of this honorific, the policies of institutions of higher education generally ask that recipients ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gas Chromatography
Gas chromatography (GC) is a common type of chromatography used in analytical chemistry for separating and analyzing compounds that can be vaporized without decomposition. Typical uses of GC include testing the purity of a particular substance, or separating the different components of a mixture. In preparative chromatography, GC can be used to prepare pure compounds from a mixture. Gas chromatography is also sometimes known as vapor-phase chromatography (VPC), or gas–liquid partition chromatography (GLPC). These alternative names, as well as their respective abbreviations, are frequently used in scientific literature. Gas chromatography is the process of separating compounds in a mixture by injecting a gaseous or liquid sample into a mobile phase, typically called the carrier gas, and passing the gas through a stationary phase. The mobile phase is usually an inert gas or an unreactive gas such as helium, argon, nitrogen or hydrogen. The stationary phase is a microscopic la ...
