Scandium is a chemical element; it has symbol Sc and atomic number 21. It is a silvery-white metallic d-block element. Historically, it has been classified as a rare-earth element, together with yttrium and the lanthanides. It was discovered in 1879 by spectral analysis of the minerals euxenite and gadolinite from Scandinavia.
William Prout FRS was an English chemist, physician, and natural theologian. He is remembered today mainly for what is called Prout's hypothesis.
James Bryant Conant was an American chemist, a transformative President of Harvard University, and the first U.S. Ambassador to West Germany. Conant obtained a Ph.D. in chemistry from Harvard in 1916. During World War I, he served in the U.S. Army, where he worked on the development of poison gases, especially Lewisite. He became an assistant professor of chemistry at Harvard University in 1919 and the Sheldon Emery Professor of Organic Chemistry in 1929. He researched the physical structures of natural products, particularly chlorophyll, and he was one of the first to explore the sometimes complex relationship between chemical equilibrium and the reaction rate of chemical processes. He studied the biochemistry of oxyhemoglobin providing insight into the disease methemoglobinemia, helped to explain the structure of chlorophyll, and contributed important insights that underlie modern theories of acid-base chemistry.
The American Chemical Society (ACS) is a scientific society based in the United States that supports scientific inquiry in the field of chemistry. Founded in 1876 at New York University, the ACS currently has more than 155,000 members at all degree levels and in all fields of chemistry, chemical engineering, and related fields. It is one of the world's largest scientific societies by membership. The ACS is a 501(c)(3) non-profit organization and holds a congressional charter under Title 36 of the United States Code. Its headquarters are located in Washington, D.C., and it has a large concentration of staff in Columbus, Ohio.
The National Chemical Laboratory (NCL) is an Indian government laboratory based in Pune, in western India.
In organic chemistry, crown ethers are cyclic chemical compounds that consist of a ring containing several ether groups (R−O−R’). The most common crown ethers are cyclic oligomers of ethylene oxide, the repeating unit being ethyleneoxy, i.e., −CH2CH2O−. Important members of this series are the tetramer (n = 4), the pentamer (n = 5), and the hexamer (n = 6). The term "crown" refers to the resemblance between the structure of a crown ether bound to a cation, and a crown sitting on a person's head. The first number in a crown ether's name refers to the number of atoms in the cycle, and the second number refers to the number of those atoms that are oxygen. Crown ethers are much broader than the oligomers of ethylene oxide; an important group are derived from catechol.
Saxitoxin (STX) is a potent neurotoxin and the best-known paralytic shellfish toxin (PST). Ingestion of saxitoxin by humans, usually by consumption of shellfish contaminated by toxic algal blooms, is responsible for the illness known as paralytic shellfish poisoning (PSP).
The American Institute of Chemical Engineers (AIChE) is a professional organization for chemical engineers. AIChE was established in 1908 to distinguish chemical engineers as professionals independent of chemists and mechanical engineers.
Chemistry education is the study of teaching and learning chemistry. It is one subset of STEM education or discipline-based education research (DBER). Topics in chemistry education include understanding how students learn chemistry and determining the most efficient methods to teach chemistry. There is a constant need to improve chemistry curricula and learning outcomes based on findings of chemistry education research (CER). Chemistry education can be improved by changing teaching methods and providing appropriate training to chemistry instructors, within many modes, including classroom lectures, demonstrations, and laboratory activities.
Bioorganic chemistry is a scientific discipline that combines organic chemistry and biochemistry. It is that branch of life science that deals with the study of biological processes using chemical methods. Protein and enzyme function are examples of these processes.
The Papyrus Graecus Holmiensis is a collection of craft recipes compiled in Egypt c. 300 AD. It is written in Greek. The Stockholm papyrus has 154 recipes for dyeing, coloring gemstones, cleaning (purifying) pearls, and imitation gold and silver. Certain of them may derive from the Pseudo-Democritus. Zosimos of Panopolis, an Egyptian alchemist of c. 300 AD, gives similar recipes. Some of these recipes are found in medieval Latin collections of technological recipes, notably the Mappae clavicula.
Passade is a municipality in the district of Plön, in Schleswig-Holstein, Germany. Passade was first mentioned in 1373. The picturesque location and the intact village structure was appreciated in 2003 with the first prize in the competition "Unser Dorf soll schöner werden". In 2004, the award was appropriated at federal level.
Staniszewo is a village in the administrative district of Gmina Barciany, within Kętrzyn County, Warmian-Masurian Voivodeship, in northern Poland, close to the border with the Kaliningrad Oblast of Russia.
Gordon Research Conferences are a group of international scientific conferences organized by a non-profit organization of the same name, since 1931 covering frontier research in the chemical, and physical and later biological, sciences, and their related technologies. The conferences have been held in the US since 1931, and have expanded to almost 200 conferences per year, since 1990 also in Europe and Asia. Conference locations are chosen partly for their scenic and often isolated nature, to encourage an informal community atmosphere. Contributions are off the record, with references to the conference in any publication strictly prohibited to encourage free discussion, often of unpublished research. In 1991, conferences were extended to cover science education.
Hitit University is a university in Çorum, Turkey, founded in 2006. The university was affiliated to Gazi University before splitting into an independent university, with existing educational units affiliated to this newly founded university in 2006.
THJ-2201 is an indazole-based synthetic cannabinoid that presumably acts as a potent agonist of the CB1 receptor and has been sold online as a designer drug.
THJ-018 (SGT-17) is a synthetic cannabinoid that is the indazole analogue of JWH-018 and has been sold online as a designer drug.
The Columbia Journal of Environmental Law is a student-run law review published at Columbia University's School of Law. The journal primarily publishes articles, notes, and book reviews discussing environmental law and policy and related subjects.
Foil Allan Miller was an American chemist and philatelist best known for his work in infrared and Raman spectroscopy. He was head of the spectroscopy division of the Mellon Institute and later professor and head of the spectroscopy laboratory at the University of Pittsburgh. Among other publications, he co-authored the books Course Notes on the Interpretation of Infrared and Raman Spectra (2004) and A Philatelic Ramble Through Chemistry (1998).
Neil Elbridge Gordon was an American chemist and educator. He is known for founding the Journal of Chemical Education and establishing the Gordon Research Conferences.
