Kyushu University
, abbreviated to , is a Japanese national university located in Fukuoka, on the island of Kyushu. It was the 4th Imperial University in Japan, ranked as 4th in 2020 Times Higher Education Japan University Rankings, one of the top 10 Designated National University and selected as a Top Type university of Top Global University Project by the Japanese government. Kyudai is considered one of the most prestigious research-oriented universities in Japan and is a member of the Alliance of Asian Liberal Arts Universities along with the University of Tokyo, Waseda University, Peking University and others.

Boronic Acid
A boronic acid is an organic compound related to boric acid () in which one of the three hydroxyl groups () is replaced by an alkyl or aryl group (represented by R in the general formula ). As a compound containing a carbon–boron bond, members of this class thus belong to the larger class of organoboranes. Boronic acids act as Lewis acids. Their unique feature is that they are capable of forming reversible covalent complexes with sugars, amino acids, hydroxamic acids, etc. (molecules with vicinal, (1,2) or occasionally (1,3) substituted Lewis base donors (alcohol, amine, carboxylate)). The p''K''a of a boronic acid is ~9, but they can form tetrahedral boronate complexes with p''K''a ~7. They are occasionally used in the area of molecular recognition to bind to saccharides for fluorescent detection or selective transport of saccharides across membranes. Boronic acids are used extensively in organic chemistry as chemical building blocks and intermediates predominantly in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kyushu University Alumni
is the third-largest island of Japan's five main islands and the most southerly of the four largest islands ( i.e. excluding Okinawa). In the past, it has been known as , and . The historical regional name referred to Kyushu and its surrounding islands. Kyushu has a land area of and a population of 14,311,224 in 2018. In the 8th-century Taihō Code reforms, Dazaifu was established as a special administrative term for the region. Geography The island is mountainous, and Japan's most active volcano, Mount Aso at , is on Kyushu. There are many other signs of tectonic activity, including numerous areas of hot springs. The most famous of these are in Beppu, on the east shore, and around Mt. Aso in central Kyushu. The island is separated from Honshu by the Kanmon Straits. Being the nearest island to the Asian continent, historically it is the gateway to Japan. The total area is which makes it the 37th largest island in the world. It's slightly larger than Taiwan island . T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Royal Society Of Chemistry
The Royal Society of Chemistry (RSC) is a learned society (professional association) in the United Kingdom with the goal of "advancing the chemistry, chemical sciences". It was formed in 1980 from the amalgamation of the Chemical Society, the Royal Institute of Chemistry, the Faraday Society, and the Society for Analytical Chemistry with a new Royal Charter and the dual role of learned society and professional body. At its inception, the Society had a combined membership of 34,000 in the UK and a further 8,000 abroad. The headquarters of the Society are at Burlington House, Piccadilly, London. It also has offices in Thomas Graham House in Cambridge (named after Thomas Graham (chemist), Thomas Graham, the first president of the Chemical Society) where ''RSC Publishing'' is based. The Society has offices in the United States, on the campuses of The University of Pennsylvania and Drexel University, at the University City Science Center in Philadelphia, Pennsylvania, in both Beijing a ...

Izatt-Christensen Award
Reed McNeil Izatt (born 10 October 1926 in Logan, Utah) is a Charles E. Maw Professor of Chemistry, Emeritus, at Brigham Young University in Provo, Utah. His field of research was macrocyclic chemistry and metal separation technologies. Early life and education Izatt was born in 1926 in Logan, Utah. His first ten years were spent on a ranch in Sumpter Valley, Oregon where he attended school in a two-room schoolhouse. He developed an interest in geology and astronomy. His family then returned to Logan, Utah and he graduated from Logan High School in 1944. On 6 June 1944, Izatt enrolled at Utah State Agricultural College (now Utah State University).

Molecular Machine
A molecular machine, nanite, or nanomachine is a molecular component that produces quasi-mechanical movements (output) in response to specific stimuli (input). In cellular biology, macromolecular machines frequently perform tasks essential for life, such as DNA replication and ATP synthesis. The expression is often more generally applied to molecules that simply mimic functions that occur at the macroscopic level. The term is also common in nanotechnology where a number of highly complex molecular machines have been proposed that are aimed at the goal of constructing a molecular assembler. For the last several decades, chemists and physicists alike have attempted, with varying degrees of success, to miniaturize machines found in the macroscopic world. Molecular machines are at the forefront of cellular biology research. The 2016 Nobel Prize in Chemistry was awarded to Jean-Pierre Sauvage, Sir J. Fraser Stoddart, and Bernard L. Feringa for the design and synthesis of molecula ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aggregation-induced Emission
Aggregation-induced emission (AIE) is a phenomenon that is observed with certain organic luminophores (fluorescent dyes). The photoemission efficiencies of most organic compounds is higher in solution than in the solid state. Photoemission from some organic compounds follows the reverse pattern, being greater in the solid than in solution. The effect is attributed to the decreased flexibility in the solid. Aggregation-induced emission enhancement The phenomenon in which organic luminophores show higher photoluminescence efficiency in the aggregated state than in solution is called aggregation-induced emission enhancement (AIEE). Some luminophores, e.g., diketopyrrolopyrrole-based and sulfonamide In organic chemistry, the sulfonamide functional group (also spelled sulphonamide) is an organosulfur group with the structure . It consists of a sulfonyl group () connected to an amine group (). Relatively speaking this group is unreactive. ...-based luminophores, only displa ...

Combinatorial Chemistry
Combinatorial chemistry comprises chemical synthetic methods that make it possible to prepare a large number (tens to thousands or even millions) of compounds in a single process. These compound libraries can be made as mixtures, sets of individual compounds or chemical structures generated by computer software. Combinatorial chemistry can be used for the synthesis of small molecules and for peptides. Strategies that allow identification of useful components of the libraries are also part of combinatorial chemistry. The methods used in combinatorial chemistry are applied outside chemistry, too. History Combinatorial chemistry had been invented by Furka Á (Eötvös Loránd University Budapest Hungary) who described the principle of it, the combinatorial synthesis and a deconvolution procedure in a document that was notarized in 1982.Furka Á.
