Fracture Toughness of Co4Sb12 and In0.1Co4Sb12 Thermoelectric Skutterudites Evaluated by Three Methods

Creator:: Eilertsen, James, Subramanian, M. A., and Kruzic, J. J.
Abstract:: Interstitially filled skutterudites are a promising class of state-of-the-art thermoelectric materials. Although thermoelectrics are exposed to significant thermal stresses, little information is known about the fracture toughness of interstitially doped skutterudites. This work explores the fracture toughness of undoped Co₄Sb₁₂ and indium doped In₀.₁Co₄Sb₁₂ skutterudites using three methods: 1) Vickers...

Coriolis analysis of several high-resolution infrared bands of bicyclo[111]pentane-d₀ and -d₁

Creator:: Perry, A., Martin, M. A., Nibler, J. W., Maki, A., Weber, A., and Blake, T. A.
Abstract:: High-resolution infrared absorption spectra have been analyzed for two bicyclo[111]pentane isotopologues, C₅H₈ (-d₀) and C₅H₇D (-d₁), where in the latter the D-atom replaces a hydrogen on the C₃ symmetry axis such that the molecular symmetry is reduced from D₃ₕ to C₃ᵥ. Two (a"₂) parallel bands, v₁₇ and v₁₈, of bicyclopentane-d₀...

Fusion of Sn-124,Sn-132 with Ca-40,Ca-48

Creator:: Kolata, J. J., Roberts, A., Howard, A. M., Shapira, D., Liang, J. F., Gross, C. J., Varner, R. L., Kohley, Z., Villano, A. N., Amro, H., Loveland, W., and Chavez, E.
Abstract:: Fusion excitation functions for the reactions of Sn-¹²⁴,Sn-¹³² with Ca-⁴⁰,Ca-⁴⁸ were measured at energies near and below the Coulomb barrier. Weak sub-barrier fusion enhancement accounted for by coupling to the first 2(+) and 3(-) states in the target and projectile was observed for Sn-¹²⁴,Sn-¹³² + Ca-⁴⁸. However, the Sn-¹²⁴,Sn-¹³² +...

Topotactic Reduction and Reoxidation of Hexagonal RCu0.5Ti0.5O3 (R =Y, Eu-Lu) Phases

Creator:: Jiang, Peng, Berthelot, Romian, Li, Jun, Sleight, A. W., and Subramanian, M. A.
Abstract:: Hexagonal AMO₂ and AMO₃ phases have the same basic structure, and intermediate compositions for this structure have been prepared by topotactic oxidation of AMO₂ phases such as RCuO₂, where R is a trivalent rare earth cation. We now find that such intermediate phases can also be prepared by topotactic reduction...

Laboratory-frame electron angular distributions: Probing the chemical environment through intramolecular electron scattering

Creator:: Patanen, M., Travnikova, O., Zahl, M. G., Söderstrom, J., Decleva, P., Thomas, T. D., Svensson, S., Mårtensson, N., Børve, K. J., Sæthre, L. J., and Miron, C.
Abstract:: Carbon 1s photoelectron asymmetry parameters β for the chlorinated and the methyl carbon atom of CH₃CH₂Cl, CH₃CHCl₂, and CH₃CCl₃ have been measured using synchrotron radiation in the 340-600 eV energy range. We provide experimental evidence that the intramolecular scattering strongly affects beta values, even far from the ionization threshold. The...

Probing structural evolution along multidimensional reaction coordinates with femtosecond stimulated Raman spectroscopy

Creator:: Frontiera, Renee R., Fang, Chong, Dasgupta, Jyotishman, and Mathies, Richard A.
Abstract:: Mapping out multidimensional potential energy surfaces has been a goal of physical chemistry for decades in the quest to both predict and control chemical reactivity. Recently a new spectroscopic approach called Femtosecond Stimulated Raman Spectroscopy or FSRS was introduced that can structurally interrogate multiple dimensions of a reactive potential energy...

Measurement of the fusion probability, P[subscript CN], for hot fusion reactions

Creator:: Yanez, R., Loveland, W., Barrett, J. S., Yao, L., Back, B. B., Zhu, S., and Khoo, T. L.
Abstract:: Abstract: Background: The cross section for forming a heavy evaporation residue in fusion reactions depends on the capture cross section, the fusion probability, P[subscript CN], i.e., the probability that the projectile-target system will evolve inside the fission saddle point to form a completely fused system rather than reseparating (quasifission), and...

High-resolution infrared studies of the ν10, ν11, ν14, and ν18 levels of [1.1.1]propellane

Creator:: Kirkpatrick, Robynne, Masiello, Tony, Martin, Matthew, Nibler, Joseph W., Maki, Arthur, Weber, Alfons, and Blake, Thomas A.
Abstract:: This paper is a continuation of earlier work in which the high resolution infrared spectrum of [1.1.1]propellane was measured and its k and l structure resolved for the first time. Here we present results from an analysis of more than 16,000 transitions involving three fundamental bands v₁₀ (E' - A'₁),...

Catalyst selective and regiodivergent O- to C- or N-carboxyl transfer of pyrazolyl carbonates: synthetic and computational studies

Creator:: Gould, Eoin, Walden, Daniel M., Kasten, Kevin, Johnston, Ryne C., Wu, Jiufeng, Slawin, Alexandra M., Mustard, Thomas J. L., Johnston, Brittany, Davies, Tony, Cheong, Paul Ha-Yeon, and Smith, Andrew D.
Abstract:: The regiodivergent O- to C- or N-carboxyl transfer of pyrazolyl carbonates is described, with DMAP giving preferential N-carboxylation and triazolinylidenes promoting selective C-carboxylation (both with up to >99 : 1 regioselectivity). An enantioselective O- to C-carboxyl variant using NHC catalysis is demonstrated (up to 92% ee), while mechanistic and DFT studies outline...

Synthesis of α-Ketoester- and α-Hydroxyester-Substituted Isoindazoles via the Thermodynamic Coarctate Cyclization of Ester-Terminated Azo-Ene-Yne Systems

Creator:: McClintock, Sean P., Forster, Nathan, Herges, Rainer, and Haley, Michael M.
Abstract:: The synthesis of isoindazoles bearing α-ketoester and α-hydroxyester groups via the coarctate cyclization of ester terminated azo-ene-yne precursors is described. Whereas previous studies on isoindazole formation have shown the reaction to proceed through a kinetic coarctate pathway, functionalization of the terminal acetylene with a methyl ester sufficiently stabilizes the carbene...
