Organic Chemistry Introduction - What Organic Chemists Do By Anne Marie Helmenstine, Ph.D. Updated April 05, 2016. Organic chemistry is more than simply the study of carbon or the study of chemicals in living organisms. Take a look at what organic chemistry is, why it is important, and what organic chemists do. What Is Organic Chemistry? Organic chemistry is the study of carbon and the study of the chemistry of life. Why Is Organic Chemistry Important? Organic chemistry is important because it is the study of life and all of the chemical reactions related to life. continue reading below our video What Does an Organic Chemist Do? An organic chemist is a chemist with a college degree in chemistry.
PubMed home Welcome to the Chemical Education Digital Library Microscale Gas Chemistry Our Gas Reaction Catalyst Tube can be used to demonstrate a variety of gas phase chemical reactions. The catalyst contains a layer of disbursed palladium atoms on a ceramic material and enclosed within a glass housing as per the fugure. Hydrogenation of alkenes occurs at very temperatures (even < 0 deg C). Gas Bags For classroom use, gases can be prepared and stored in sealable plastic food bags equipped with a dispensing tube. Mini-Ozone Generator Ozone is generated for in situ use. Left: Apparatus dispensing O3 to a flask.

[IUPAC]IUPAC.org Résumer un cours ou un article avec XMind Comment résumer un cours ? Ou un article ? Ou tout autre texte pas trop long ? Beaucoup de personnes éprouvent des difficultés à résumer : étudiants en période d’examen, journalistes qui doivent présenter une nouvelle loi en 1500 signes, cadres à qui leur supérieur vient de demander un rapport en « en deux pages maxi » sur la situation de l’agence de Trifouillis-les-Oies… Par où commencer ? Autant de points qui suscitent l’angoisse, voire la panique chez certains… et pas chez les plus stupides, contrairement à ce qu’on pourrait croire. D’abord un peu de théorie. Qu’est-ce qu’un résumé ? C’est une version raccourcie d’un texte existant. Jetez un coup d’oeil sur cette carte heuristique : elle illustre la méthode que je propose aux étudiants que j’aide en coaching scolaire et aux participants de nos Ateliers Triple A : Apprendre A Apprendre. Un résumé de cours avec XMind Première étape : la préparation Ne plongez pas directement sur votre stylo, votre crayon ou votre clavier. Comment ?
A particle like slow light: Particles known as 'Weyl fermions' were discovered in materials with strong interaction between electrons. Just like light particles, they have no mass but nonetheless they move extremely slowly. -- ScienceDaily Weyl particles are not particles which can move on their own (like electrons or protons), they only exist as 'quasiparticles' within a solid material. Now, for the first time, such Weyl particles has been found in a special kind of material, which is particularly interesting for novel technological applications: scientists have measured Weyl fermions in a material with highly correlated electrons. Surprisingly, these fermions move very slowly, despite having no mass. There was great excitement back in 2015, when it was first possible to measure these 'Weyl fermions' -- outlandish, massless particles that had been predicted almost 90 years earlier by German mathematician, physician and philosopher, Hermann Weyl. Quasiparticles: only possible in a solid state "Quasiparticles are not particles in the conventional sense, but rather excitations of a system consisting of many interacting particles," explains Prof. A "light speed" of just 100 m/s In search of new effects
