Reference excerpt

Onkar Nath Srivastava (31 December 1942 – 24 April 2021) was an Indian material physicist, an Emeritus professor of Banaras Hindu University and the vice president for India and South Asia of the International Association for Hydrogen Energy, who was known for his contributions to the disciplines of nanotechnology and hydrogen energy. He was the author of two books and over 440 scientific papers and a recipient of several honors including Shanti Swarup Bhatnagar Prize, the highest Indian award in the science and technology categories. The Government of India awarded him the fourth highest civilian honour of the Padma Shri, in 2016, for his contributions to science and engineering.

Biography Srivastava was born on 31 December 1942, in Varanasi, the holy city of Lord Shiva in the Indian state of Uttar Pradesh. He secured his master's degree in Physics (MSc) in 1961 from Banaras Hindu University (BHU) and followed it up with a doctoral degree (PhD) from the same institution, under the guidance of renowned physicist Ajit Ram Verma, in 1966. After doing his post doctoral research at Cornell University, USA, he returned to India to start his career as a lecturer at Banaras Hindu University where he served in different capacities as that of a reader, professor, head of the department of physics and the coordinator of the Centre of Advance Studies-Hydrogen Energy Centre. After his superannuation from service, he continues his association with the university as a professor emeritus and as an associate faculty member of Condensed Matter Experiment research program of the university. Srivastava, a former member of the board of directors of The World Academy of Sciences, was the vice president (India & South Asia) of the International Association of Hydrogen Energy, having been elected to the position in 2012, where he also serves as a member of their editorial board. Under his guidance, the Hydrogen Energy Centre of BHU was involved in advance research on the practical applications of hydrogen fuel, in association with the Ministry of New and Renewable Energy and the Department of Science and Technology (DST), of the Government of India. He published two books, Crystallography Applied to Solid State Physics and Formation and phase stability of Al based quasicrystals: Quasicrystal and over 440 scientific papers. He delivered keynote addresses in a number of science seminars and undertook several projects for various government agencies; Nanoscience and Technology of the Department of Science and Technology (2005–2010), Support to Hydrogen Energy Centre (2007–2012), Development & Demonstration of Hydrogen Catalytic Combustion Cookers (2007–2010), Development & Demonstration of Hydrogen Fueled three wheelers (2009–2012), Mission Mode Project on Hydrogen Storage Materials (Hydride) (2009–2014), all of the Ministry of New and Renewable Energy, and Synthesis Characterization and Properties of Single Walled Carbon Nanotubes (2009–2012) of the Defence Research and Development Organization are some of the notable ones. He was also involved in organizing science conferences and mentored 87 doctoral students. Srivastava died from COVID-19 in April 2021.

Awards and honors

In 1988, The Council of Scientific and Industrial Research (CSIR) awarded Srivastava the Shanti Swarup Bhatnagar Prize, the highest Indian science award for his contributions on high temperature oxide superconductors, growth, characterization and application of hydrogen storage materials. He received the Goyal Prize in Physical Sciences and K. S. Rao Memorial Award on Renewable Energy in 2000 and two years later, the Indian Science Congress Association awarded him the 2002 Homi J. Bhabha Award in Applied Sciences. In 2009, he was recognized by the ICSC with the Material Research Society of India-ICSC Award. The National Academy of Sciences, India elected him as their fellow in 1989, followed by the Indian National Science Academy in 1994 and the International Association of Hydrogen Energy in 2010. He was also an elected fellow of the Asia Pacific Academy of Materials, International Academy of Physical Sciences and the New York Academy of Sciences.

Worked examples

Example 1 — a first encounter with Onkar Nath Srivastava

Start with the simplest possible case. Write down what Onkar Nath Srivastava claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, 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 Onkar Nath Srivastava 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 Onkar Nath Srivastava 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 Onkar Nath Srivastava

In research: Onkar Nath Srivastava appears in astronomy 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 Onkar Nath Srivastava 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: Onkar Nath Srivastava is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1942 births, 2021 deaths, 20th-century Indian physicists, so understanding it makes those chapters shorter.
In everyday life: Look for Onkar Nath Srivastava 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.
