Biography

M. Periasamy, born to Duraisamy Mariappanadar and Krishnammal couple on 6 October 1952, at Srivilliputtur, a historical town in Virudhunagar district of the south Indian state of Tamil Nadu, did his early schooling at Kammapatty Primary School and C. M. S. High School, Srivilliputtur and joined St. John's College, Palayamkottai from where he completed his pre-university course in 1970. His graduate (1970–73) and master's courses (1973–75) were done at American College, Madurai and he secured a PhD from the Indian Institute of Science in 1979 studying Mechanism of Oxidation of Aromatic Rings under the guidance of M. V. Bhatt. He moved to the US the same year where he did his post-doctoral studies at the laboratory of Herbert C. Brown, a Nobel laureate at Purdue University, researching on Nonclassical Ion Problem, one of the favorite topics of Brown. On his return to India in 1982, he joined the School of Chemistry of the University of Hyderabad where he serves as a professor since 1993. In between, he served as a visiting scientist at National Center for Scientific Research in 1995 and as a visiting professor at University of Amsterdam, (1996) and University of Marburg (1997). Periasamy is married to Hemavathy Paramasivam and the couple has two children. The family lives in Hyderabad.

Legacy Periasamy is noted for his development of new synthetic protocols such as the construction of diverse types of molecular structures using carbon metal bonds. He leads a team which have developed new procedures for preparing organometallics and chiral reagents and many of them are in use with laboratories and industries, NaBH4/I2 reagent system designed by his team is one such process which has become industry standard. He has also developed cost effective process for generating electricity from biomass and solar energy. His researches have been documented in a number of articles; ResearchGate, an online article repository, has listed 276 of them. He serves as a member of the International Scientific Committee on Boron Chemistry since 2007 and has been associated with several science journals as a member of their editorial boards.

Awards and honors Periasamy received the Professor B. H. Iyer Medal of the Indian Institute of Science in 1979 and the Dr. Husain Zaheer Science Foundation Young Scientist Award of the Indian Institute of Chemical Technology in 1992. The Indian Academy of Sciences elected him as their fellow in 1994 and the Council of Scientific and Industrial Research awarded him the Shanti Swarup Bhatnagar Prize, one of the highest Indian science awards, in 1996. A J. C. Bose National Fellow of the Department of Science and Technology during 2006–11, he became a fellow of the Indian National Science Academy in 2005 and received the Silver Medal by the Chemical Research Society of India in 2007. He has delivered several award orations including Professor N. S. Narasimhan Endowment Award of Pune University (1995), Professor A. B. Kulkarni Endowment Lecture of University of Mumbai (1999), and Professor D. P. Chakraborty 60th Birth Anniversary Award of Indian Chemical Society (2004).

Worked examples

Example 1 — a first encounter with Mariappan Periasamy

Start with the simplest possible case. Write down what Mariappan Periasamy claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In chemistry, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Mariappan Periasamy before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Mariappan Periasamy ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Mariappan Periasamy

In research: Mariappan Periasamy appears in chemistry research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Mariappan Periasamy in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Mariappan Periasamy is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1952 births, Academic staff of Marburg University, Academic staff of the University of Amsterdam, so understanding it makes those chapters shorter.
In everyday life: Look for Mariappan Periasamy outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
