Naval Materials Research Laboratory
Naval Materials Research Laboratory (NMRL) is an Indian defence laboratory of the Defence Research and Development Organisation (DRDO). Located at Ambernath, in Thane district, Maharashtra. It develops materials and alloys for Naval use, and is a single-window agency for all materials requirement of the Indian Navy. NMRL is organized under the Naval Research & Development Directorate of DRDO. The present director of NMRL is Shri Prashant T Rojatkar. History NMRL was established in 1953 as the Naval Chemical and Metallurgical Laboratory, an in-house laboratory of the Navy, located at the Naval Dockyard, Mumbai. It was brought under the administrative control of DRDO in the early 1960s. The laboratory is located in its own technical-cum residential complex at Ambernath, Maharashtra. The laboratory still has its erstwhile infrastructure intact in Naval Dockyard, Mumbai, without any physical scientific or administrative presence.

24 Paraganas District
4 (four) is a number, numeral and digit. It is the natural number following 3 and preceding 5. It is the smallest semiprime and composite number, and is considered unlucky in many East Asian cultures. In mathematics Four is the smallest composite number, its proper divisors being and . Four is the sum and product of two with itself: 2 + 2 = 4 = 2 x 2, the only number b such that a + a = b = a x a, which also makes four the smallest squared prime number p^. In Knuth's up-arrow notation, , and so forth, for any number of up arrows. By consequence, four is the only square one more than a prime number, specifically three. The sum of the first four prime numbers two + three + five + seven is the only sum of four consecutive prime numbers that yields an odd prime number, seventeen, which is the fourth super-prime. Four lies between the first proper pair of twin primes, three and five, which are the first two Fermat primes, like seventeen, which is the third. On the other ha ...

Research And Development In India
Research is "creative and systematic work undertaken to increase the stock of knowledge". It involves the collection, organization and analysis of evidence to increase understanding of a topic, characterized by a particular attentiveness to controlling sources of bias and error. These activities are characterized by accounting and controlling for biases. A research project may be an expansion on past work in the field. To test the validity of instruments, procedures, or experiments, research may replicate elements of prior projects or the project as a whole. The primary purposes of basic research (as opposed to applied research) are documentation, discovery, interpretation, and the research and development (R&D) of methods and systems for the advancement of human knowledge. Approaches to research depend on epistemologies, which vary considerably both within and between humanities and sciences. There are several forms of research: scientific, humanities, artistic, economic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Materials Science Institutes
Material is a substance or mixture of substances that constitutes an object. Materials can be pure or impure, living or non-living matter. Materials can be classified on the basis of their physical and chemical properties, or on their geological origin or biological function. Materials science is the study of materials, their properties and their applications. Raw materials can be processed in different ways to influence their properties, by purification, shaping or the introduction of other materials. New materials can be produced from raw materials by synthesis. In industry, materials are inputs to manufacturing processes to produce products or more complex materials. Historical elements Materials chart the history of humanity. The system of the three prehistoric ages ( Stone Age, Bronze Age, Iron Age) were succeeded by historical ages: steel age in the 19th century, polymer age in the middle of the following century (plastic age) and silicon age in the second half of t ...

The Hindu
''The Hindu'' is an Indian English-language daily newspaper owned by The Hindu Group, headquartered in Chennai, Tamil Nadu. It began as a weekly in 1878 and became a daily in 1889. It is one of the Indian newspapers of record and the second most circulated English-language newspaper in India, after '' The Times of India''. , ''The Hindu'' is published from 21 locations across 11 states of India. ''The Hindu'' has been a family-owned newspaper since 1905, when it was purchased by S. Kasturi Ranga Iyengar from the original founders. It is now jointly owned by Iyengar's descendants, referred to as the "Kasturi family", who serve as the directors of the holding company. The current chairperson of the group is Malini Parthasarathy, a great-granddaughter of Iyengar. Except for a period of about two years, when S. Varadarajan held the editorship of the newspaper, the editorial positions of the paper were always held by members of the family or held under their direction. His ...

Adsorption
Adsorption is the adhesion of atoms, ions or molecules from a gas, liquid or dissolved solid to a surface. This process creates a film of the ''adsorbate'' on the surface of the ''adsorbent''. This process differs from absorption, in which a fluid (the ''absorbate'') is dissolved by or permeates a liquid or solid (the ''absorbent''). Adsorption is a '' surface phenomenon'', while absorption involves the whole volume of the material, although adsorption does often precede absorption. The term '' sorption'' encompasses both processes, while '' desorption'' is the reverse of it. Like surface tension, adsorption is a consequence of surface energy. In a bulk material, all the bonding requirements (be they ionic, covalent or metallic) of the constituent atoms of the material are fulfilled by other atoms in the material. However, atoms on the surface of the adsorbent are not wholly surrounded by other adsorbent atoms and therefore can attract adsorbates. The exact nature ...

Maharashtra
Maharashtra (; , abbr. MH or Maha) is a state in the western peninsular region of India occupying a substantial portion of the Deccan Plateau. Maharashtra is the second-most populous state in India and the second-most populous country subdivision globally. It was formed on 1 May 1960 by splitting the bilingual Bombay State, which had existed since 1956, into majority Marathi-speaking Maharashtra and Gujarati-speaking Gujarat. Maharashtra is home to the Marathi people, the predominant ethno-linguistic group, who speak the Marathi language, the official language of the state. The state is divided into 6 divisions and 36 districts, with the state capital being Mumbai, the most populous urban area in India, and Nagpur serving as the winter capital, which also hosts the winter session of the state legislature. Godavari and Krishna are the two major rivers in the state. Forests cover 16.47 per cent of the state's geographical area. Out of the total cultivable land in the s ...

Co-precipitation
In chemistry, coprecipitation (CPT) or co-precipitation is the carrying down by a precipitate of substances normally soluble under the conditions employed. Analogously, in medicine, coprecipitation is specifically the precipitation of an unbound "antigen along with an antigen-antibody complex". Coprecipitation is an important topic in chemical analysis, where it can be undesirable, but can also be usefully exploited. In gravimetric analysis, which consists on precipitating the analyte and measuring its mass to determine its concentration or purity, coprecipitation is a problem because undesired impurities often coprecipitate with the analyte, resulting in excess mass. This problem can often be mitigated by "digestion" (waiting for the precipitate to equilibrate and form larger and purer particles) or by redissolving the sample and precipitating it again.Harvey, D. (2000). ''Modern Analytical Chemistry''. McGraw-Hill. On the other hand, in the analysis of trace elements, as i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
