Ram Seshadri is an American materials scientist,chemist and academic. He is the associate dean for research in the College of Engineering as well as distinguished professor in the Materials Department and the Department of Chemistry and Biochemistry,and the Fred and Linda R. Wudl Professor of Materials Science at University of California,Santa Barbara. [1]
Seshadri is known for his contributions to understanding the relationships between structure,composition,and properties in functional inorganic materials. His research also encompasses materials for energy conversion and storage,such as Li-ion and related battery materials,magnetocaloric materials,and hybrid halide optoelectronic materials. Furthermore,he is the recipient of 2004 National Science Foundation Career Award,and the 2005 Exxon Mobil Solid State Chemistry Faculty Fellowship of the American Chemical Society. Furthermore,he has published over 400 scientific research publications in leading academic journals. [2]
Seshadri has served on the editorial boards of numerous academic journals and is the editor of the journal Annual Review of Materials Research . [3]
Seshadri completed his Bachelor's in Chemistry from St. Stephen's College at Delhi University in 1989. Later,he earned his M.S. in chemistry,followed by a Ph.D. under the supervision of professor C. N. R. Rao in Solid State Chemistry,from the Indian Institute of Science,in 1995. [1]
Seshadri began his academic career in 1999 as an assistant professor in the Solid State and Structural Chemistry Unit at the Indian Institute of Chemistry. From 2002 to 2006,he was an assistant professor in the Materials Department at the University of California,Santa Barbara. In 2006,he was promoted to associate professor in the Department of Chemistry and Biochemistry,serving until 2008. He then became a professor in the Materials Department and the Department of Chemistry and Biochemistry at the same institution. Furthermore,he is a fellow of Royal Society of Chemistry,American Association for the Advancement of Science,American Physical Society and the Neutron Scattering Society of America. [4] Since 2020,he has served as a distinguished professor in the Materials Department and the Department of Chemistry and Biochemistry,as well as the associate dean for research in the College of Engineering at the University of California,Santa Barbara. [1]
Seshadri research is multi-faceted. In 2013,he co-authored a paper on phosphor materials for solid-state white lighting,focusing on Ce3+ and Eu2+ doped materials,their excitation and reemission properties,and guidelines for developing new host materials. [5] That same year,he worked with to optimize Ce3+ phosphors for high-brightness LEDs. They used the Debye temperature and band gap of host materials to assess structural rigidity and efficiency,proposing a sorting diagram for identifying suitable hosts and addressing related challenges. [6] In 2014,Seshadri investigated the superior thermal stability and luminescence efficiency of intermediate compositions of SrxBa2–xSiO4 phosphors. He attributed these properties to optimal cation bonding and lattice rigidity,based on experimental and theoretical analyses. [7]
Seshadri has also researched the behavior of compounds with lone pair ions and developed guidelines for determining when these lone pairs influence the crystal chemistry of the compounds. In 2003,he collaborated with others to us density functional theory to explore lone pair behavior and material instabilities in IV-VI chalcogenides,revealing that anion 𝑝states played a significant role in lone pair localization and that these materials exhibited a balance between structural distortions and metallic tendencies,affecting their dielectric properties and phonon modes. [8] Through his 2016 study,he examined how the lone pair electrons of Sn2+ in CsSnBr3 influenced its structural and optical properties,revealing temperature-dependent distortions and transitions between different crystal structures. [9] Furthermore,in 2023,he examined how lone pairs of electrons influence the electronic structure and properties of crystalline solids,highlighting their role in various materials and their potential as a design element for tuning material functions. [10]
Seshadri has also conducted research on the rapid screening of magnetocaloric materials and photovoltaics,and has made significant contributions to the fields of frustrated magnetism and magnetoelectric multiferroics. In this regard,his 2014 study explored how Mn₃O₄exhibited phase coexistence and lattice strain below 42 K due to magnetic ordering,with a nearly equal presence of tetragonal and orthorhombic phases. This study suggested that such phase coexistence might be common in other magnetic spinels at low temperatures. [11] Later in 2017,Seshadri introduced a computational method to predict the magnetocaloric effect of materials using the magnetic deformation ΣM,which was validated experimentally and used to identify promising new compounds for magnetic refrigeration. [12] More recently in 2019,he evaluated around 33,000 inorganic compounds for their potential as photovoltaic materials,identified about 200 high-performing candidates with promising efficiencies and carrier properties,and provided detailed data for further research.

Gadolinium is a chemical element;it has symbol Gd and atomic number 64. Gadolinium is a silvery-white metal when oxidation is removed. It is a malleable and ductile rare-earth element. Gadolinium reacts with atmospheric oxygen or moisture slowly to form a black coating. Gadolinium below its Curie point of 20 °C (68 °F) is ferromagnetic,with an attraction to a magnetic field higher than that of nickel. Above this temperature it is the most paramagnetic element. It is found in nature only in an oxidized form. When separated,it usually has impurities of the other rare earths because of their similar chemical properties.
The lanthanide or lanthanoid series of chemical elements comprises at least the 14 metallic chemical elements with atomic numbers 57–70,from lanthanum through ytterbium. In the periodic table,they fill the 4f orbitals. Lutetium is also sometimes considered a lanthanide,despite being a d-block element and a transition metal.
Zinc phosphide (Zn3P2) is an inorganic chemical compound. It is a grey solid,although commercial samples are often dark or even black. It is used as a rodenticide. Zn3P2 is a II-V semiconductor with a direct band gap of 1.5 eV and may have applications in photovoltaic cells. A second compound exists in the zinc-phosphorus system,zinc diphosphide (ZnP2).

Iron boride refers to various inorganic compounds with the formula FexBy. Two main iron borides are FeB and Fe2B. Some iron borides possess useful properties such as magnetism,electrical conductivity,corrosion resistance and extreme hardness. Some iron borides have found use as hardening coatings for iron. Iron borides have properties of ceramics such as high hardness,and properties of metal properties,such as thermal conductivity and electrical conductivity. Boride coatings on iron are superior mechanical,frictional,and anti-corrosive. Iron monoboride (FeB) is a grey powder that is insoluble in water. FeB is harder than Fe2B,but is more brittle and more easily fractured upon impact.
Werner Urland is a German chemist whose name is imprinted in the pioneering implementation of the Angular Overlap Model for the interpretation of optical and magnetic properties of rare-earth coordination compounds.
