Ravi Bhushan

Ravi Bhushan is a chemistry topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Ravi Bhushan rather than just read about it. In short: Ravi Bhushan (born 12 April 1953, in Muzaffarnagar, India) was a Professor of Chemistry at Indian Institute of Technology Roorkee who worked in the areas of natural products chemistry, protein chemistry, and chiral analysis by liquid chromatography. Education and academic career Bhushan began his education in his native India, completing his undergraduate and master's degrees from the University of Jodhpur.

Key takeaways

Ravi Bhushan belongs to chemistry; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Ravi Bhushan to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Ravi Bhushan from memory before moving on to harder problems.

Reference excerpt

Ravi Bhushan (born 12 April 1953, in Muzaffarnagar, India) was a Professor of Chemistry at Indian Institute of Technology Roorkee who worked in the areas of natural products chemistry, protein chemistry, and chiral analysis by liquid chromatography.

Education and academic career Bhushan began his education in his native India, completing his undergraduate and master's degrees from the University of Jodhpur. He received his Ph.D. in chemistry (working on structure elucidation of natural products isolated from certain desert plants) in 1978 at the University of Jodhpur. Bhushan joined as a lecturer at the University of Roorkee (now Indian Institute of Technology Roorkee, India) in 1979 and was later selected for the position of full professor of chemistry in 1996 and served there till retirement in 2018.

Research He started his research in the chemistry of natural products. At Washington State University he established early steps in the metabolism of d-neomethyl-α-D-glucoside in pipermint (Mentha piperita) rhizomes via in vivo studies. Bhushan developed a de novo method for direct resolution of certain racemates by liquid chromatography. Later, the approach was applied for direct enantioseparation of several active pharmaceutical ingredients (APIs). It is now an established approach in literature. 1994 onwards, the method was extended to such resolutions by ligand exchange principle. The method is of significant importance to pharmaceutical industry and analytical laboratories associated with regulatory agencies for determination and control of enantiomeric purity (and isolation of native enantiomers) of a variety of APIs since many of them are marketed and administered as racemic mixture while only one enantiomer is therapeutically useful. Bhushan supervised the Ph.D. theses of > 30 scholars and has published more than 270 research papers.

Editorial work Bhushan is a member of editorial board of

Biomedical Chromatography, (John Wiley & Sons, UK, since Jan 1996); Bioanalysis (Future Science Group, UK, since 2011), and Acta Chromatographica (Akademiai Kiado, Hungary, since 2012).

Honours and awards 1988 Alexander von Humboldt fellowship of Germany: Research with Jürgen Martens at the University of Oldenburg and Hans Brückner University of Giessen. 1992 European Economic Community Fellowship: Research with Peter Shewry University of Bristol 1993 Fellow of the Royal Society of Chemistry 2001 Fellow of the National Academy of Sciences India

Worked examples

Example 1 — a first encounter with Ravi Bhushan

Start with the simplest possible case. Write down what Ravi Bhushan 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 Ravi Bhushan 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 Ravi Bhushan 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 Ravi Bhushan

In research: Ravi Bhushan 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 Ravi Bhushan 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: Ravi Bhushan is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1953 births, 20th-century Indian chemists, 21st-century Indian chemists, so understanding it makes those chapters shorter.
In everyday life: Look for Ravi Bhushan 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.
