THERMODYNAMICS OF THE POINT DEFECTS IN THE METALLIC PHASE OF THE SAMARIUM MONOSULPHIDE
Journal of Vasyl Stefanyk Precarpathian National University, 2016 The equilibrial values of the vacancy concentration of chalcogen and antistructural samarium atoms in metallic phase of SmS were calculated by minimization the crystal thermodynamic potential. It was determined that the dominant defects are

Tripyrrolidinophosphoric acid triamide as an activator in samarium diiodide reductions
, 2010 The electrochemical and spectrophotometric characterization of the complex formed from samarium diiodide and 4 equiv of tripyrrolidinophosphoric acid triamide (TPPA) is presented. Kinetic studies indicate that the SmI(2)/TPPA complex possesses reactivity

Reductive Samarium Catalysis Enabled By A Thermochemical Roadmap [PDF]
Samarium diiodide is a versatile single-electron reductant. Its reactivity is modulated by recruitment of a wide range of additives to its large coordination sphere. Binding of strong Lewis bases produces more potent Sm(II) reductants, while polar protic

Particle-Size-Induced Valence Changes in Samarium Clusters [PDF]
, 1981 Samarium clusters exhibit mixed-valence behavior which is sensitive to particle size. XPS and UPS data show samarium to be primarily divalent (4f{sup 6} ) at small particle size.

Radioactivity of Samarium [PDF]
Nature, 1935 SEVERAL workers have investigated the radioactivity of samarium, and it is established that this element emits short-range-particles. Mader1 has also reported the existence of a group of particles of range 1.37 cm., which he believes to be protons. To obtain fuller information about these particles, I have introduced samarium sulphate into the emulsion

Hydrothermal synthesis, characterization and catalytic performance of La3+ and Sm3+ - doped Bi2Mn2O7 nanocatalysts for Biginelli reactions [PDF]
Journal of Nanostructures, 2019 La3+ and Sm3+ - doped Bi2Mn2O7 nanocatalysts were synthesized in 1 M NaOH aqueous solution, via a stoichiometric 1:1 Bi:Mn molar ratio hydrothermal method at 180 °C for 48 h. Bi(NO3)3, MnO2, La(NO3)3 and Sm2O3 were used as raw materials.

Central Nervous System Tumors Among Infants in Canada: A Report From CYP‐C
Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Central nervous system (CNS) tumors in infants are rare, pose unique clinical challenges, and lack large‐scale evidence‐based data to guide management. This study seeks to describe CNS tumors in Canadian infants and to compare their outcomes with those of older children.
