On 5 May 2021, Joko Widodo signed Presidential Decree No. 33/2021, effectively establishing BRIN as the sole national research agency and decreeing that all Indonesian national research agencies—such as the Indonesian Institute of Sciences (LIPI), the Agency for the Assessment and Application of Technology [] (BPPT), the National Nuclear Energy Agency of Indonesia [] (BATAN), and the ...
The Dutch returned to Indonesia and resumed control of the council, the institute was renamed Organisatie voor Natuurwetenschappelijk Onderzoek (OPIPA, Organisation for Scientific Research) in 1948. In 1956 the organization was nationalized as Majelis Ilmu Pengetahuan Indonesia (MIPI, Indonesian Sciences Council).
Organic chemistry is a subdiscipline within chemistry involving the scientific study of the structure, properties, and reactions of organic compounds and organic materials, i.e., matter in its various forms that contain carbon atoms. [1]
Elution principle of column chromatography. In analytical and organic chemistry, elution is the process of extracting one material from another by washing with a solvent: washing of loaded ion-exchange resins to remove captured ions, or eluting proteins or other biopolymers from a gel electrophoresis or chromatography column.
In one important reaction type, a main group organometallic compound of the type R-M (where R = organic group, M = main group centre metal atom) reacts with an organic halide of the type R'-X with formation of a new carbon-carbon bond in the product R-R'. The most common type of coupling reaction is the cross coupling reaction.
The competition puts students from the thirty-four provinces of Indonesia, and winners of the competition are further selected to represent Indonesia in their respective subjects' International Science Olympiad. [1] In addition, Indonesian public universities are required to accept medal-winners of the competition into their undergraduate ...
Organic synthesis is an important chemical process that is integral to many scientific fields. Examples of fields beyond chemistry that require organic synthesis include the medical industry, pharmaceutical industry, and many more. Organic processes allow for the industrial-scale creation of pharmaceutical products.
Acetic anhydride, like most organic acid anhydrides, is a flexible molecule with a nonplanar structure. [4] The pi system linkage through the central oxygen offers very weak resonance stabilization compared to the dipole-dipole repulsion between the two carbonyl oxygens. The energy barriers to bond rotation between each of the optimal aplanar ...
