Aqueous Complexation of Thorium(IV), Uranium(IV), Neptunium(IV), Plutonium(III/IV), and Cerium(III/IV) with DTPA

Creator:: Brown, M. Alex, Paulenova, Alena, and Gelis, Artem V.
Abstract:: Aqueous complexation of Th(IV), U(IV), Np(IV), Pu(III/IV), and Ce(III/IV) with DTPA was studied by potentiometry, absorption spectrophotometry, and cyclic voltammetry at 1 M ionic strength and 25 °C. The stability constants for the 1:1 complex of each trivalent and tetravalent metal were calculated. From the potentiometric data, we report stability...

Dielectric and polarization experiments in high loss dielectrics: A word of caution

Creator:: Maglione, M. and Subramanian, M. A.
Abstract:: The recent quest for improved functional materials like high permittivity dielectrics and/or multiferroics has triggered an intense wave of research. Many materials have been checked for their dielectric permittivity or their polarization state. In this report, we call for caution when samples are simultaneously displaying an insulating behavior and a...

Rapid Microwave Synthesis of the Iron Arsenides NdFeAsO and NdFe₀.₉Co₀.₁AsO

Creator:: Muir, Sean, Rachdi, Omar, and Subramanian, Mas
Abstract:: The future of iron pnictide superconductors in technology is still undecided. While these materials are now known to possess high critical temperatures and critical magnetic fields processing methods for these materials are still in their infancy. Recently we have been investigating possible ways to speed up the synthetic process for...

Magnetodielectric Effects from Spin Fluctuations in Isostructural Ferromagnetic and Antiferromagnetic Systems

Creator:: Lawes, G., Ramirez, A. P., Varma, C. M., and Subramanian, M. A.
Abstract:: We report on the effects of spin fluctuations, magnetic ordering, and external magnetic field on the dielectric constant of the ferromagnet SeCuO₃, and the antiferromagnet TeCuO₃. A model based on the coupling between uniform polarization and the q-dependent spin-spin correlation function is presented to explain the different behaviors for these...

Resonantly enhanced multiphoton ionization and zero kinetic energy photoelectron spectroscopy of Benzo[e]pyrene

Creator:: Harthcock, Colin, Zhang, Jie, and Kong, Wei
Abstract:: We report zero kinetic energy (ZEKE) photoelectron spectroscopy via resonantly enhanced multiphoton ionization (REMPI) for benzo[e]pyrene. Extensive vibronic coupling between the first electronically excited state and a nearby state allows b₂ symmetric modes to be observed which would normally be Franck-Condon (FC) disallowed. These vibronic modes are comparable in intensity...

Effects of molecular potential and geometry on atomic core-level photoemission over an extended energy range: The case study of the CO molecule

Creator:: Kukk, E., Travnikova, O., Mondal, S., Kimura, M., Sakai, K., Miron, C., Martín, F., Ueda, K., Ayuso, D., Thomas, T. D., Decleva, P., Patanen, M., Argenti, L., Plésiat, E., Palacios, A., and Kooser, K.
Abstract:: We report an experimental and theoretical study of single-molecule inner-shell photoemission measured over an extended range of photon energies. The vibrational intensity ratios I (nu = 1)/I (nu = 0) from the C 1s photoelectron spectra of carbon monoxide, although mostly determined by the bond length change upon ionization, are...

Composition and sources of organic tracers in aerosol particles of industrial central India

Creator:: Giri, Basant, Patel, Khageshwar S., Jaiswal, Nitin K., Sharma, Saroj, Ambade, Balram, Wang, Wentao, Simonich, Staci L. Massey, and Simoneit, Bernd R. T.
Abstract:: Organic aerosols are important atmospheric components, and their formation and sources represent important aspects of urban air quality and health effects. Asia, including India, is the largest global source of aerosol particles due to regional natural advection (e.g. desert and soil dust) and anthropogenic activities (e.g. emissions from traffic, industry...

Zero kinetic energy photoelectron spectroscopy of jet cooled benzo[a]pyrene from resonantly enhanced multiphoton ionization

Creator:: Zhang, Jie, Harthcock, Colin, Han, Fangyuan, and Kong, Wei
Abstract:: We report zero kinetic energy (ZEKE) photoelectron spectroscopy of benzo[a]pyrene (BaP) via resonantly enhanced multiphoton ionization (REMPI). Our analysis concentrates on the vibrational modes of the first excited state (S₁) and those of the ground cationic state (D₀). Similar to pyrene, another peri-condensed polycyclic aromatic hydrocarbon we have investigated, the...

Efficient Fabrication of Nanoporous Si and Si/Ge Enabled by a Heat Scavenger in Magnesiothermic Reactions

Creator:: Luo, Wei, Wang, Xingfeng, Meyers, Colin, Wannenmacher, Nick, Sirisaksoontorn, Weekit, Lerner, Michael M., and Ji, Xiulei
Abstract:: Magnesiothermic reduction can directly convert SiO₂ into Si nanostructures. Despite intense efforts, efficient fabrication of highly nanoporous silicon by Mg still remains a significant challenge due to the exothermic reaction nature. By employing table salt (NaCl) as a heat scavenger for the magnesiothermic reduction, we demonstrate an effective route to...
