James M. Tour is an American nanotechnologist and both Professor of Materials Science and NanoEngineering, and Professor of Computer Science at Rice University in Houston, Texas, United States.


Tour received degrees from Syracuse University (BS, 1981), Purdue University (PhD, 1986) and completed postdoctoral work at the University of Wisconsin–Madison (1986–1987) and Stanford University (1987–1988).[1]


He worked in molecular electronics and molecular switching molecules. Tour's work on carbon materials chemistry is broad and encompasses fullerene purification,[2][3] composites,[4][5] conductive inks for radio frequencies identification tags,[6][7] carbon nanoreporters for identifying oil downhole,[8][9] graphene synthesis from cookies and insects,[10] graphitic electronic devices,[11][12] carbon particle drug delivery for treatment of traumatic brain injury,[13][14] the merging of 2D graphene with 1D nanotubes to make a conjoined hybrid material,[15] a new graphene-nanotube 2D material called rebar graphene,[16] graphene quantum dots from coal,[17] gas barrier composites,[18] graphene nanoribbon deicing films,[19] supercapacitors and battery device structures,[20][21] and water splitting to H2 and O2 using metal chalcogenides.[22] His work with the synthesis of graphene oxide,[23] its mechanism of formation,[24] and its use in capturing radionuclides from water is extensive.[25] Tour has developed oxide based electronic memories that can also be transparent and built onto flexible substrates.[26] More recently, he has been using porous metal structures to make renewable energy devices including batteries and supercapacitors, as well as electronic memories.[27] Tour also worked on nanocars, single-molecule vehicles with four independently rotating wheels, axles, and light-activated motors.[28] Tour was the first to show that Feringa-based motors[29] can be used to move a molecule on a surface using light[30] as opposed to electric current from an STM tip. His early independent career focused upon the synthesis of conjugated polymers and precise oligomers.[31] Tour was also a founder of the Molecular Electronics Corporation. He holds joint appointments in the departments of chemistry, computer science, and materials science and nanoengineering at Rice University.

He has also been involved in other work, such as NanoKids, an interactive learning DVD to teach children fundamentals of chemistry and physics, SciRave, Dance Dance revolution and Guitar Hero packages to teach science concepts to middle-school students and SciRave-STEM for elementary school children, and much work on carbon nanotubes and graphene.[32][33][34][35] Tour has over 640 research publications and over 120 patents, with an H-index = 129 (107 by ISI Web of Science) and i10 index = 538 with total citations over 77,000 (Google Scholar).

In the Scientific American article "Better Killing Through Chemistry",[36] which appeared a few months after the September 11 attacks, Tour highlighted the ease of obtaining chemical weapon precursors in the United States.

In 2001, Tour signed the Discovery Institute's "A Scientific Dissent From Darwinism", a controversial petition which the intelligent design movement uses to promote intelligent design by attempting to cast doubt on evolution.[37][38] To those who "are disconcerted or even angered that I signed a statement back in 2001" he responded "I have been labeled as an Intelligent Design (ID) proponent. I am not. I do not know how to use science to prove intelligent design although some others might. I am sympathetic to the arguments on the matter and I find some of them intriguing, but the scientific proof is not there, in my opinion. So I prefer to be free of that ID label."[39]

He had also said that he felt the explanations offered by evolution are incomplete, and he found it hard to believe that nature can produce the machinery of cells through random processes.[37] On his website, he writes that "From what I can see, microevolution is a fact" and "there is no argument regarding microevolution. The core of the debate for me, therefore, is the extrapolation of microevolution to macroevolution."[39]

In Lee Strobel's book The Case For Faith - the following commentary is attributed to Tour: "I build molecules for a living, I can't begin to tell you how difficult that job is. I stand in awe of God because of what he has done through his creation. Only a rookie who knows nothing about science would say science takes away from faith. If you really study science, it will bring you closer to God."[40]


Tour was inducted into the National Academy of Inventors in 2015.[41] He was named among "The 50 most Influential Scientists in the World Today" by TheBestSchools.org in 2014.[42] Tour was named "Scientist of the Year" by R&D Magazine in 2013.[43] Tour won the ACS Nano Lectureship Award from the American Chemical Society in 2012. Tour was ranked one of the top 10 chemists in the world over the past decade by Thomson Reuters in 2009. That year, he was also made a fellow of the American Association for the Advancement of Science. Other notable awards won by Tour include the 2008 Feynman Prize in Nanotechnology, the NASA Space Act Award in 2008 for his development of carbon nanotube reinforced elastomers, the Arthur C. Cope Scholar Award from the American Chemical Society (ACS) for his achievements in organic chemistry in 2007, the Small Times magazine's Innovator of the Year Award in 2006, the Southern Chemist of the Year Award from ACS in 2005, the Honda Innovation Award for Nanocars in 2005, the NSF Presidential Young Investigator Award in 1990, and the Office of Naval Research Young Investigator Award in 1989. In 2005, Tour's journal article "Directional Control in Thermally Driven Single-Molecule Nanocars" was ranked the Most Accessed Journal Article by the American Chemical Society.[44] Tour has twice won the George R. Brown Award for Superior Teaching at Rice University in 2007 and 2012. In 2016, Tour was listas as an ISI highly cited researcher.[45]

A Scientific Dissent From Darwinism[edit]

Tour was one of a small number of nationally prominent researchers among five hundred scientists and engineers whose names appear on Discovery Institute's petition, "A Scientific Dissent From Darwinism",[37] which states "We are skeptical of claims for the ability of random mutation and natural selection to account for the complexity of life. Careful examination of the evidence for Darwinian theory should be encouraged."[46] The two-sentence statement has been widely used by its sponsor, the Discovery Institute, and some of their supporters in a national campaign to discredit evolution and to promote intelligent design.

Tour said that the explanations offered by evolution are incomplete, and he found it hard to believe that nature can produce the machinery of cells through random processes. Despite this, he said he remained open-minded about evolution. He was quoted as saying "I respect that work" and being open to the possibility that future research will complete the explanations.[37]
