Abstract:

Through the classical molecular dynamics, the melting properties of the the tungsten and aluminum mixed clusters are explored. By using simulated annealing the structure of the mixed cluster is obtained. It is found that the Al atoms tend to locate on the surface of the clusters. The melting behaviors of the clusters are analyzed in detail by the atom-resolved Lindemann index. The curves of Lindemann index show that the melting process of the can experience three steps which is not common in the melting process of the nanoclusters.

Abstract:

The melting process of Pd-Ni alloy nanobelts with different Ni atom content has been simulated by molecular dynamic (MD) method. The radial distribution function, the Lindemann index, and pair analysis method were used to characterize Pd-Ni nanobelt models in simulation. The results indicate that the melting temperature of Pd-Ni nanobelt with composition far from pure metal was lower than that of other models, and the breaking point of the nanobelt can be illustrated by the Lindemann index. Pair analysis indicates that the number of FCC pairs will decrease and almost disappear at melting point

Abstract:

A small titanium-decorated fullerene cluster (C60[TiH2]6)7 was studied by MD simulation over a wide range of energy, from the solid state to the vaporization of the nanosystem. The low energy, solid state structure of the cluster was obtained as a deformed pentagonal bipyramid. Several physical characteristics: the radial distribution function, the mean square displacement, the translational velocity autocorrelation function, translational diffusion coefficient, Lindemann index, etc., were calculated for a wide range of energy in the system.

Molecular dynamics (MDs) simulations were used to explore the thermal stability of Au nanoparticles (NPs) with decahedral, cuboctahedral, icosahedral and Marks NPs.

The Lindemann index, radial distribution function, deformation parameters, mean square displacement and self-diffusivity have been used to characterize the structure variation during heating. This work may inspire researchers to prepare Marks NPs and apply them in d

Structural optimization of ternary Cu–Ag–Au nanoalloys with 38 and 55 atoms was performed using the basin-hopping algorithm and the Gupta many-body potential was adopted to model interatomic interactions.

It is found that the size has little effect on the segregation phenomena of Cu, Ag and Au atoms in the Cu–Ag–Au ternary nanoalloy. We es

In 2016, it is shown that the ion conductivity of La2LiHO3 can be attributed to pure H– conduction, not mixed with electron, by demonstrating the electrochemical reaction of H– charge transfer in an all-solid-state TiH2/La2LiHO3/Ti cell.1 Since the milestone study, the material investigation of hydride-ion conductors has been actively con

New approaches targeting pathways in NSCLC have emerged, resulting in encouraging new treatments that benefit LUAD patients, but very few advances have been made in the treatment options for LUSC which accounts for ~30% of lung cancer cases.

The area under the receiver operating characteristic curve values of 0.993 and 0.989 for tra

Abstract:

ABSTRACTOvergrazing affects the grass‐livestock balance and endangers grassland ecological security. Despite extensive studies conducted on identifying and quantifying grazing intensity, there is still room for improvement in the research on gridding grazing intensity, particularly in areas with limited data on the Qinghai–Tibet Plateau. Therefore, we proposed a grazing intensity spatialization method using geographically weighted random forest (GWRF) to gain further insights into the spatial heterogeneity of alpine grassland grazing intensity. This method incorporates multiple remote sensing

Abstract:

Indonesian EFL students faced online teaching and learning in such a rapid process. Therefore, this research was carried out to search for EFL students in Indonesia about their responses on teaching and learning online. This research applied the action research method with the paradigm of quantitative descriptive approach. Data for this research was collected via an online questionnaire, distributed to one class size sample consisting of 32 students in the even semester of the 2019/2020 academic year at one of the private colleges in the West Sumatra province of Indonesia. The data were analys
