Morphine. Synthesis of morphine-like alkaloids in chemistry describes the total synthesis of the natural morphinan class of alkaloids that includes codeine, morphine, oripavine, and thebaine and the closely related semisynthetic analogs methorphan, buprenorphine, hydromorphone, hydrocodone, isocodeine, naltrexone, nalbuphine, oxymorphone, oxycodone, and naloxone.
RXNO:0000021. The Sandmeyer reaction is a chemical reaction used to synthesize aryl halides from aryl diazonium salts using copper salts as reagents or catalysts. [1][2][3][4] It is an example of a radical-nucleophilic aromatic substitution. The Sandmeyer reaction provides a method through which one can perform unique transformations on benzene ...
The GATE is used as a requirement for financial assistance (e.g. scholarships) for a number of programs, though criteria differ by admitting institution. [2] In December 2015, the University Grants Commission and MHRD announced that the scholarship for GATE-qualified master's degree students is increased by 55% from ₹ 8,000 (US$96) per month to ₹ 12,400 (US$150) per month.
The Debye–Hückel theory was proposed by Peter Debye and Erich Hückel as a theoretical explanation for departures from ideality in solutions of electrolytes and plasmas. [1] It is a linearized Poisson–Boltzmann model, which assumes an extremely simplified model of electrolyte solution but nevertheless gave accurate predictions of mean activity coefficients for ions in dilute solution.
t. e. Physical chemistry is the study of macroscopic and microscopic phenomena in chemical systems in terms of the principles, practices, and concepts of physics such as motion, energy, force, time, thermodynamics, quantum chemistry, statistical mechanics, analytical dynamics and chemical equilibria. Physical chemistry, in contrast to chemical ...
A candidate should have appeared for the Class XII (or equivalent) examination for the first time in either 2023 or 2024 with Physics, Chemistry, and Mathematics as compulsory subjects with a minimum of 75% aggregate marks or in the top 20 percentile in their 10+2 Board Examination conducted by their respective board for General,EWS and OBC ...
Biotechnology is a multidisciplinary field that involves the integration of natural sciences and engineering sciences in order to achieve the application of organisms and parts thereof for products and services. [1] The term biotechnology was first used by Károly Ereky in 1919 [2] to refer to the production of products from raw materials with ...
Solid-state chemistry, also sometimes referred as materials chemistry, is the study of the synthesis, structure, and properties of solid phase materials.It therefore has a strong overlap with solid-state physics, mineralogy, crystallography, ceramics, metallurgy, thermodynamics, materials science and electronics with a focus on the synthesis of novel materials and their characterization.
