In the agricultural lands of south-western Australia, salinity severely affects about 1 million hectares, and there is also widespread occurrence of potassium (K) deficiency. This study investigated whether the effects of sodium (Na) on crop K nutrition vary with plant salt sensitivity. In a glasshouse experiment with…

Polarized (VV) and depolarized (VH) static (SLS) and dynamic light scattering (DLS) experiments were conducted in dispersions of sterically stabilized silver nanoprisms in three different solvents where strong plasmon-enhanced scattering was observed. In the dilute regime, hydrodynamic sizes obtained from VV and VH we…

In this work, a spatially resolved sampling technique is applied to characterize the performance of a C 3 H 8 CPO reformer and to compare it with that of a CH 4 reformer. The case of Rh-coated honeycomb catalysts is examined. The axial profiles show that higher temperatures are reached in C 3 H 8 CPO, especially at th…

We investigated the adsorption of CO 2 on PdO(101) using temperature-programmed desorption (TPD) and dispersion-corrected density functional theory calculations (DFT-D3). We find that CO 2 desorbs from PdO(101) in two main TPD peaks (ε 1 and ε 2 ) centered at ∼176 and 120 K and estimate that the average binding energi…

Valence electron concentration is a viable chemical tool to control the crystal structure and magnetism of Gd 5 Ge 4 . A decrease in the valence electron concentration achieved through the substitution of Eu 2+ for Gd 3+ leads to the formation of the interslab Ge–Ge dimers, phase transitions to the Gd 5 Si 2 Ge 2 - an…

The aim of this study was to determine fabric shear by the yarn pull-out method. For this purpose three fabric types were tested. The fabric width/length ratio and the number of pull-out ends were identified as important test parameters. After the yarn in the fabric was pulled from the top ravel region before the star…

In order to identify the ingredients of thermal rectification, we analytically investigate the heat flow in the asymmetric classical and quantum self-consistent harmonic chains of oscillators. We confirm the absence of rectification in the classical version of the model, and, for the quantum analog, we show that the c…
