We report results on the flow of dilute aqueous solutions of hydrolysed poly(acrylamide) (HPAA) through beds of spheres packed in simple cubic and body-centred cubic crystallographic arrays. Pressure drop measurements made across the arrays as a function of the flow rate have been used to estimate the specific viscosities of the HPAA solutions as a function of the superficial strain rate. It is...

The twin boundary structures in the BCC transition metals are determined by analyzing generalized stacking fault energy curves and complete structural relaxation of twinned crystals utilizing both interatomic potentials density functional theory calculations. In contrast to crystallographic description elements metals, pure reflection structure has been found be unstable all seven considered. I...

Recent results for the Ising model with first ($J_1$) and second ($J_2$) neighbour interactions on body-centered cubic (bcc) lattice suggest that this can host signatures of strong frustration, including Schottky anomalies residual entropy, as well as, a spin-liquid-like phase [E. Jur\v{c}i\v{s}inov\'a M. Jur\v{c}i\v{s}in, Phys. Rev. B, 101 214443 (2020)]. Motivated by these findings, we invest...
