Article
Electrochemical water splitting is one of the most efficient techniques to produce hydrogen in an environmentally friendly way. However, a sluggish anodic reaction, namely oxygen evolution reaction (OER), requires the use of an efficient electrocatalyst for achieving economic hydrogen production. Transition‐metal‐based layered double hydroxides (LD...

Full-text available
In the crystallisation of nanomaterials, an assembly-based mechanism termed ‘oriented attachment’ (OA) has recently been recognised as an alternative mechanism of crystal growth that cannot be explained by the classical theory. However, attachment alignment during OA is not currently tuneable because its mechanism is poorly understood. Here, we ide...
Article
Development of an efficient and stable electrocatalyst for oxygen evolution reaction (OER) is crucial to make hydrogen generated via water splitting as a sustainable fuel. Nickel iron layered double hydroxides...
Article
We investigated the thermoelectric transport properties of InTe1-δ (δ = 0.0, 0.1, and 0.2) compounds and interpreted their unusual behavior in terms of electronic and phonon band dispersions. The temperature-dependent electrical resistivity ρ(T) and Seebeck coefficient S(T) exhibit the charge density wave (CDW) transition near 87 K for InTe1-δ (δ =...
Article
The InTe has intrinsically low lattice thermal conductivity κL originating from the anharmonic bonding of In1+ ion in the lattice, which scatters the phonons. Here we report the enhancement of thermoelectric properties in Te-deficient InTe1−δ (δ = 0, 0.01, 0.1, and 0.2) polycrystalline compounds by lattice softening and energy band gap opening. Te-...
Article
A numerical model to predict mechanical properties of Ni-base superalloys for turbine disk applications is developed by modifying and combining previous models that consider various microstructural factors. Modifications are made so that as many necessary model parameters as possible, whose values have been obtained from mechanical measurements and...
Article
Interatomic potentials for the Ni-Ti and Ni-Al-Ti systems have been developed based on the second nearest-neighbor modified embedded-atom method (2NN-MEAM) formalism. The Ni-Ti binary potential reproduces fundamental materials properties (structural, elastic, thermodynamic, and thermal stability) of alloy systems in reasonable agreement with experi...
Article
An interatomic potential for the Ti–Al binary system has been developed based on the second nearest-neighbor modified embedded-atom method (2NN MEAM) formalism. This potential describes fundamental materials properties (structural, thermodynamic, elastic, defect, deformation and thermal properties) of Ti–Al alloys in good agreements with experiment...
Article
A mathematical model to predict creep properties of Ni-based superalloys at intermediate temperature ranges based on microstructure, process and creep condition, and material properties has been developed by modifying and combining previous models. Modifications are made so that as many necessary model parameters as possible, whose values have been...
Article
Interatomic potentials for the Ni–Co binary and Ni–Al–Co ternary systems have been developed on the basis of the second nearest-neighbor modified embedded-atom method (2NN MEAM) formalism. The potentials describe structural, thermodynamic, deformation and defect properties of solid solution phases or compound phases in reasonable agreements with ex...
Article
The effects of the porosity, size, shape and mutual connectivity of pores on the elastic property of pure titanium were investigated using an atomistic simulation (molecular statics). The study concluded that the elasticity of porous Ti is mainly governed by its porosity. The results showed that the size and shape of the pores do not have a signifi...
