 Ajayan is a pioneer in the field of [[nanotechnology]].<ref>Trynano interview – {{cite web |url=http://www.trynano.org/ajayan.html |title=Archived copy |access-date=2011-06-07 |url-status=dead |archive-url=https://web.archive.org/web/20120325030855/http://www.trynano.org/ajayan.html |archive-date=25 March 2012 |df=dmy-all }}</ref> His PhD work (1989) involved the characterisation of gold nanoparticles on oxide substrates and their phase instabilities. He was involved in the early development of  carbon nanotubes. From 1991 onwards, at the NEC Fundamental Research Laboratory in Tsukuba, Japan, he worked with [[Sumio Iijima]] and [[Thomas Ebbesen]] and published some of the early works in carbon nanotubes.<ref>First papers on nanotubes {{cite web |url=http://www.owlnet.rice.edu/~Robert.Vajtai/Ajayan/smallest.pdf |title=Archived copy |access-date=2011-06-07 |url-status=dead |archive-url=https://web.archive.org/web/20120317152049/http://www.owlnet.rice.edu/~Robert.Vajtai/Ajayan/smallest.pdf |archive-date=17 March 2012 |df=dmy-all }} {{cite web |url=http://www.owlnet.rice.edu/~Robert.Vajtai/Ajayan/large_scale.pdf |title=Archived copy |access-date=2011-06-07 |url-status=dead |archive-url=https://web.archive.org/web/20120317152114/http://www.owlnet.rice.edu/~Robert.Vajtai/Ajayan/large_scale.pdf |archive-date=17 March 2012 |df=dmy-all }} {{cite web |url=http://www.owlnet.rice.edu/~Robert.Vajtai/Ajayan/capillarity.pdf |title=Archived copy |access-date=2011-06-07 |url-status=dead |archive-url=https://web.archive.org/web/20120317152149/http://www.owlnet.rice.edu/~Robert.Vajtai/Ajayan/capillarity.pdf |archive-date=17 March 2012 |df=dmy-all }}</ref> During the past two decades he has published more than 400 papers on various aspects of carbon nanostructures, mostly on nanotubes and recently on graphene <ref>J Rafiee, X Mi, H Gullapalli, AV Thomas, F Yavari, Y Shi, PM Ajayan, NA Koratkar, Wetting transparency of grapheneNature Materials 11 (3), 217–222.</ref> and other layered materials such as boron nitride. Ajayan's research interests are broad, focusing on nanomaterials development for a variety of applications such as energy storage, composites, electronics and sensors. His publications have earned more than 68,000 citations on [[Google Scholar]] and a h-index of 120 until September 2015.<ref name="Ajayan PM Google Scholar">{{cite web | url=https://scholar.google.co.in/citations?user=S5oLGEgAAAAJ&hl=en | title=Ajayan PM Google Scholar | publisher=Google Scholar | date=2015 | access-date=September 13, 2015}}</ref> He has to his credit, two Guinness World Records for creating the smallest brush<ref>Guinness record – smallest  brush http://www.nanotech-now.com/news.cgi?story_id=14632 https://www.npr.org/templates/story/story.php?storyId=4700495 (video)</ref> and the darkest material.<ref>6.
