A generalization of some Huang--Johnson semifields
In [H. Huang, N.L. Johnson: Semifield planes of order 82, Discrete Math., 80 (1990)], the authors exhibited seven sporadic semifields of order 26, with left nucleus F2 3 and center F2. Following the notation of that paper, these examples are referred as the Huang-Johnson semifields of type II, III, IV, V, V I, V II and V III. In [N. L. Johnson, V. Jha, M. Biliotti: Handbook of Finite Translation Planes, Pure and Applied Mathematics, Taylor Books, 2007], the question whether these semifields are contained in larger families, rather then sporadic, is posed. In this paper, we first prove that the Huang-Johnson semifield of type V I is isotopic to a cyclic semifield, whereas those of types V II and V III belong to infinite families recently constructed in [N.L. Johnson, G. Marino, O. Polverino, R. Trombetti: Semifields of order q6 with left nucleus F q 3 and center Fq, Finite Fields Appl., 14 (2008)] and [G.L. Ebert, G. Marino, O. Polverino, R. Trombetti: Infinite families of new semifields, Combinatorica, 6 (2009)]. Then, Huang-Johnson semifields of type II and III are extended to new infinite families of semifields of order q6, existing for every prime power q

The L–G phase transition in binary Cu–Zr metallic liquids
An identified first-order glass transition from a liquid-like disordered phase (L-phase) to a heterogeneous, elastically rigid, solid-like phase (G-phase).The authors recently reported that undercooled liquid Ag and Ag–Cu alloys both exhibit a first order phase transition from the homogeneous liquid (L-phase) to a heterogeneous solid-like G-phase under isothermal evolution. Here, we report a similar L–G transition and heterogenous G-phase in simulations of liquid Cu–Zr bulk glass. The thermodynamic description and kinetic features (viscosity) of the L-G-phase transition in Cu–Zr simulations suggest it corresponds to experimentally reported liquid–liquid phase transitions in Vitreloy 1 (Vit1) and other Cu–Zr-bearing bulk glass forming alloys. The Cu–Zr G-phase has icosahedrally ordered cores versus fcc/hcp core structures in Ag and Ag–Cu with a notably smaller heterogeneity length scale Λ . We propose the L–G transition is a phenomenon in metallic liquids associated with the emergence of elastic rigidity. The heterogeneous core–shell nano-composite structure likely results from accommodating strain mismatch of stiff core regions by more compliant intervening liquid-like medium.An identified first-order glass transition from a liquid-like disordered phase (L-phase) to a heterogeneous, elastically rigid, solid-like phase (G-phase).The authors recently reported that undercooled liquid Ag and Ag–Cu alloys both exhibit a first order phase transition from the homogeneous liquid (L-phase) to a heterogeneous solid-like G-phase under isothermal evolution.
