Mas Subramanian, (born 1954 [1] ), is a solid-state materials scientist at Oregon State University in Corvallis, Oregon. He is a University Distinguished Professor [2] and the Milton Harris Chair of Materials Science in the university's Department of Chemistry. His work in solid-state chemistry on structure-property relationships of inorganic compounds has led to several breakthrough discoveries of novel functional materials, many of which have found usage in various applications. Subramanian has authored 400 research publications and holds 60 patents. His publications have received more than 30,000 citations (h-index: 75).

Early life and education

Subramanian was born and raised in Chennai, India. [3] Subramanian received his B.S. in chemistry from the University of Madras, in 1975 and received a M.S. in inorganic chemistry from the same university in 1977. Subramanian's master's thesis featured analysis of various minerals and alloy compounds. [4] In 1982 Mas completed his Ph.D. in solid state chemistry on pyrochlore oxides at the Indian Institute of Technology, Madras, India, under the guidance of G. V. Subba Rao. The introduction to his thesis is a pyrochlore review that remains his most cited work to date. [5] From 1982 to 1984, he was a NSF Post Doctoral Fellow under the guidance of Abraham Clearfield at Texas A&M University, College Station, Texas.

Scientific career

In 1984, Subramanian joined the Central R&D department at the DuPont Experimental Station in Wilmington, Delaware, [6] eventually becoming a DuPont Research Fellow in 2002. He has made numerous contributions to the fields of ceramics, superconductors, dielectrics, catalysis, thermoelectrics, multiferroics, ionic conductors, and organic synthesis. His notable discoveries include: zeolites as precursors to electronic ceramics, [7] new Bi and Tl-containing superconductors, [8] catalysts for Fischer-Tropsch synthesis, [9] and hydrofluorocarbons (HFCs), [10] colossal dielectrics (CCTO), [11] [12] colossal magnetoresistance (GMR) oxides, [13] [14] and skutterudite thermoelectrics. [15] His work on fluoroaromatic synthesis [16] is one of his most notable achievements.

In 2006, Subramanian joined Oregon State University as the Milton Harris Chair Professor of Materials Science, where his research is dedicated to the design and synthesis of novel functional materials for emerging applications in energy, environment, and electronics. He and his team, at Oregon State University, work on various topics such as pigments, thermoelectrics, high-temperature superconductivity, magnetoresistivity, solid fast ion conductors, high-K dielectrics, and topological insulators. In 2009, his team discovered a novel durable blue pigment, YInMn Blue, [17] the first discovery of a new blue pigment since cobalt was discovered in 1802. [3] [18] Subramanian has given numerous public lectures all over the world on YInMn Blue, including TEDxSalem [19] and TEDxUNC. [20] This discovery has been featured in various international media outlets (such as The New York Times, TIME, National Geographic, Smithsonian, [21] Bloomberg Businessweek, [22] and WBUR [23] ), and has attracted global attention from corporations and museums, like Nike, Crayola, and the Harvard Art Museum. In June 2021, Subramanian provided YInMn Blue to Sir Martyn Poliakoff for use in the Periodic Videos educational web series. [24]

Subramanian has served as a member of the editorial board for the Journal of Materials Chemistry (1995–2001), Chemistry of Materials (2000–2006), Materials Research Bulletin (2006–present), and the Journal of Solid State Chemistry (2009–present), and is continues to serve as an editor for two international academic journals, Solid State Sciences, and Progress in Solid State Chemistry.

Manganese is a chemical element; it has symbol Mn and atomic number 25. It is a hard, brittle, silvery metal, often found in minerals in combination with iron. Manganese was first isolated in the 1770s. It is a transition metal with a multifaceted array of industrial alloy uses, particularly in stainless steels. It improves strength, workability, and resistance to wear. Manganese oxide is used as an oxidising agent; as a rubber additive; and in glass making, fertilisers, and ceramics. Manganese sulfate can be used as a fungicide.

Pyrochlore2Nb2O6(OH,F) is a mineral group of the niobium end member of the pyrochlore supergroup. Pyrochlore is also a term for the crystal structure Fd3m. The name is from the Greek πῦρ, fire, and χλωρός, green because it typically turns green on ignition in classic blowpipe analysis.

Colossal magnetoresistance (CMR) is a property of some materials, mostly manganese-based perovskite oxides, that enables them to dramatically change their electrical resistance in the presence of a magnetic field. The magnetoresistance of conventional materials enables changes in resistance of up to 5%, but materials featuring CMR may demonstrate resistance changes by orders of magnitude.

<span class="mw-page-title-main">Heusler compound</span> Type of metallic alloy

Heusler compounds are magnetic intermetallics with face-centered cubic crystal structure and a composition of XYZ (half-Heuslers) or X2YZ (full-Heuslers), where X and Y are transition metals and Z is in the p-block. The term derives from the name of German mining engineer and chemist Friedrich Heusler, who studied such a compound (Cu2MnAl) in 1903. Many of these compounds exhibit properties relevant to spintronics, such as magnetoresistance, variations of the Hall effect, ferro-, antiferro-, and ferrimagnetism, half- and semimetallicity, semiconductivity with spin filter ability, superconductivity, topological band structure and are actively studied as thermoelectric materials. Their magnetism results from a double-exchange mechanism between neighboring magnetic ions. Manganese, which sits at the body centers of the cubic structure, was the magnetic ion in the first Heusler compound discovered. (See the Bethe–Slater curve for details of why this happens.)

<span class="mw-page-title-main">YInMn Blue</span> Inorganic blue pigment

YInMn Blue, also known as Oregon Blue or Mas Blue, is an inorganic blue pigment that was discovered by Mas Subramanian and his (then) graduate student, Andrew Smith, at Oregon State University in 2009. The pigment is noteworthy for its vibrant, near-perfect blue color and unusually high NIR reflectance. The chemical compound has a unique crystal structure in which trivalent manganese ions in the trigonal bipyramidal coordination are responsible for the observed intense blue color. Since the initial discovery, the fundamental principles of colour science have been explored extensively by the Subramanian research team at Oregon State University, resulting in a wide range of rationally designed novel green, purple, and orange pigments, all through intentional addition of a chromophore in the trigonal bipyramidal coordination environment.

Blue pigments are natural or synthetic materials, usually made from minerals and insoluble with water, used to make the blue colors in painting and other arts. The raw material of the earliest blue pigment was lapis lazuli from mines in Afghanistan, that was refined into the pigment ultramarine. Since the late 18th and 19th century, blue pigments are largely synthetic, manufactured in laboratories and factories.
