Surface polar optical phonon interaction induced many-body effects and hot-electron relaxation in graphene

, 2013
We theoretically study various aspects of the electron-surface optical phonon interaction effects in graphene on a substrate made of polar materials. We calculate the electron self-energy in the presence of the surface phonon-mediated electron-electron ...

Constructing Stable Sub/Surface Structure to Boost Superior Cyclabilities of Single‐Crystalline Ni‐Rich Cathode

Advanced Science
Under prolonged high‐voltage cycling, single‐crystalline Ni‐rich cathodes are prone to severe transition metal dissolution, irreversible phase transformations, and reduced structural stability, which significantly hinder their practical application ...

Solar energy converter using surface plasma waves [PDF]

, 1984
Sunlight is dispersed over a diffraction grating formed on the surface of a conducting film on a substrate. The angular dispersion controls the effective grating period so that a matching spectrum of surface plasmons is excited for parallel processing on

Dissociation of hydrogen molecules on the clean and hydrogen-preadsorbed Be(0001) surface

, 2011
Using first-principles calculations, we systematically study the potential energy surfaces and dissociation processes for hydrogen molecules on the clean and hydrogen-preadsorbed Be(0001) surfaces.

Enhanced hydrogen evolution reaction activity through samarium-doped nickel phosphide (Ni2P) electrocatalyst

Scientific Reports
Hydrogen evolution reaction (HER) stands out among conventional hydrogen production processes by featuring excellent advantages. However, the uncompetitive production cost due to the low energy efficiency has hindered its development, necessitating the ...

Oxidation and mineralization rates of harmful organic chemicals in hydroxyl radical induced reactions

Ecotoxicology and Environmental Safety
In most of advanced oxidation processes (AOPs) used to destroy harmful organic chemicals in water/wastewater hydroxyl radical (•OH) reactions oxidize (increasing the oxygen/carbon ratio in the molecules) and mineralize (transforming them to inorganic ...

Symmetry and Surface Symmetry Energies in Finite Nuclei

, 2010
A study of properties of the symmetry energy of nuclei is presented based on density functional theory. Calculations for finite nuclei are given so that the study includes isospin dependent surface symmetry considerations as well as isospin independent ...

Bent surface free energy differences from simulation

, 2000
We present a calculation of the change of free energy of a solid surface upon bending of the solid. It is based on extracting the surface stress through a molecular dynamics simulation of a bent slab by using a generalized stress theorem formula, and ...

Artificial intelligence approach for estimating energy density of liquid metal batteries

Scientific Reports
Achieving a high energy density in liquid metal batteries (LMBs) still remains a big challenge. Due to the multitude of affecting parameters within the system, traditional ways may not fully capture the complexity of LMBs.

Non-universal equilibrium crystal shape results from sticky steps

, 2011
The anisotropic surface free energy, Andreev surface free energy, and equilibrium crystal shape (ECS) z=z(x,y) are calculated numerically using a transfer matrix approach with the density matrix renormalization group (DMRG) method.
