Three solvothermal systems Ln/As/Se/en, Ln/As/Se/dien and Ln/As/Se/(en+trien) (Ln = lanthanide excluding Pm, en = ethylenediamine, dien = diethylenetriamine, trien = triethylenetetramine) were investigated in detail across the lanthanide series, and ternary lanthanide selenidoarsenates [Ln(en)(3)(H(2)O)(mu-eta(1),eta(1)-AsSe(4))] (Ln = La(1a), Ce(1b), Nd(1c)), [Ln(en)(4)]AsSe(4) x 0.5 en (Ln = ...

Changes in macromolecular mobility during the thermal oxidation of epoxy-amine thermoset networks are addressed this study. Three systems, cured with DGEBA and three similar aliphatic hardeners – ethylenediamine (EDA), diethylenetriamine (DETA), triethylenetetramine (TETA) aged at 160°C characterized by dynamic mechanical analysis (DMA). Results show a split single initial α relaxation peak agi...

BACKGROUND Generally, attenuation correction is made by incorporating a linear attenuation coefficient, which is based on the attenuation coefficient map (mu-map) created from a computed tomography scan, into the ordered subsets-expectation maximization reconstruction method in non-uniform domains. A non-uniform Chang's attenuation correction method that uses the mu-map created from a computed ...

Zinc (Zn) deficiency constrains crop yield and quality, but soil factors influencing Zn availability to plants reactions of applied fertilizer are not fully understood. This work is aimed at studying in the use efficiency fertilizers by as affected properties particularly available P. We performed a pot experiment involving four consecutive crops fertilized with sulfate using 36 soils. The cumu...
