Tailoring single-ion magnet properties of coordination polymer CHDyNO (Dy-CP) using the radial effective charge model (RECM) and superposition model (SPM).

We investigate Dy-based coordination polymer CHDyNO (Dy-CP) exhibiting single-ion magnet (SIM) properties, , quantum tunnelling of magnetization (QTM), magnetic anisotropy, magnetic relaxation, and effective energy barrier (). To elucidate the underlying mechanisms, crystal field parameters (CFPs) for Dy ions were modelled using the radial effective charge model (RECM) and superposition model (SPM), and the computational packages SIMPRE and SPECTRE. The modelled CFPs enable the prediction of the energy levels and associated wave functions, which successfully explain the field-induced Dy-CP SIM properties.

Eu ions as a crystal-field probe for low-symmetry sites in doped phosphors - a case study: Eu at triclinic sites in LiRE(BO) (RE = Y, Gd), YBO and ZnO and at trigonal sites in YAl(BO).

We present crystal-field (CF) calculations of energy levels () of Eu ions doped in various hosts aimed at exploring the low-symmetry properties of CF parameters (CFPs) and reliability of CFP modelling with decreasing site symmetry. The hosts studied are: LiY(BO), LiGd(BO), YBO, and ZnO with Eu at triclinic sites; YAl(BO) with Eu ions at trigonal symmetry. Two independent CFP modelling approaches utilizing the hosts' structural data are employed: the exchange charge model (ECM) and the superposition model (SPM).

Influence of e-Beam Irradiation on the Physicochemical Properties of Poly(polyol Succinate-co-Butylene Succinate) Ester Elastomers.

The purpose of this research was synthesis and electron beam modification of novel ester elastomers consisting of sugar alcohol-succinic acid block and butylene glycol-succinic acid block. Four different alditols were used in the synthesis-sorbitol, erythritol, xylitol, and glycerol. The materials were irradiated with doses of 50, 100, and 150 kGy in order to determine which dose is the most beneficial.
