Thermal energy has been considered to propagate by wave-like phonons with well-defined wave vectors in crystalline materials. In this work, we demonstrate a completely different thermal conduction scenario in crystalline rare earth niobates, RE3NbO7

We report the pressure (P) dependent Curie temperature, Tc (P) in a FeCoNiCuMn high entropy alloy (HEA). We analyze Tc (P) in terms of d-orbital contraction to explain changes in magnetic exchange interactions (Jex). Considerations of the d-radius co

Single-crystalline niobium pentoxide nanowires (NWs) of length 10–15 μm and diameter 100–200 nm are synthesized by thermal oxidation of niobium substrates in a mild vacuum (3–10 mbar). Amorphous Al₂O₃ shells of varying thicknesses (10, 30,

The structure and energy associated with interfaces between the BCC and HCP lattices (β and α phase, respectively) in titanium alloys with commonly used β stabilizers were analyzed. For this purpose, the crystallographic structure of the matching

The edge-to-edge matching (E2EM) model and electron back-scatter diffraction (EBSD) technique are used to explore the grain refinement mechanism of commercially pure Al through the addition of Ti and Zr elements. EBSD results show that there are favo

In this manuscript, we attempt to clarify the capability of utilisation of α-FeSi2 nanocrystals as a buffer layer for growth of monocrystalline/high-quality β-FeSi2 direct-gap semiconductor from the point of view of the crystal lattice misfits and

As a kind of ternary diboride ceramic phase, MgAlB4 can grow into whiskers via in situ reaction in aluminum matrix, which effectively solves the reinforcement dispersion and interface bonding problems in the preparation of the whiskers reinforced alu

High temperature thermal transport in insulators has been conjectured to be subject to a Planckian bound on the transport lifetime $\tau \gtrsim \tau_\text{Pl} \equiv \hbar/(k_B T)$, despite phonon dynamics being entirely classical at these temperatu

Four double atom catalysts (DACs) with controllable interatomic distances were achieved via solventless ball-milling, among which double-atom Ni2/N–C showed good selectivity and superior catalytic activity to single-atom Ni1/N–C for r-WGS reactio
