The Frustration-induced Ferroelectricity of a Manganite Tricolor Superlattice with Artificially Broken Symmetry

open access: yesScientific Reports, 2017
In this paper, [(La0.9Sr0.1MnO3)n/(Pa0.9Ca0.1MnO3)n/(La0.9Sb0.1MnO3)n]m superlattices films have been deposited on (001) Nb:SrTiO3 substrates by a laser molecular-beam epitaxy technology.

Effect of Alloying on the Nucleation and Growth of Laves Phase in the 9–10%Cr-3%Co Martensitic Steels during Creep

open access: yesMetals, 2020
Five Co-modified P92-type steels with different contents of Cr, W, Mo, B, N, and Re have been examined to evaluate the effect of the chemical composition on the evolution of Laves phase during creep at 650 °C. The creep tests have been carried out at 650

pkCSM: Predicting Small-Molecule Pharmacokinetic and Toxicity Properties Using Graph-Based Signatures

open access: yesJournal of Medicinal Chemistry, 2015
Drug development has a high attrition rate, with poor pharmacokinetic and safety properties a significant hurdle. Computational approaches may help minimize these risks.

Properties of patchy colloidal particles close to a surface: a Monte Carlo and density functional study [PDF]

open access: yes, 2012
We investigate the behavior of a patchy particle model close to a hard-wall via Monte Carlo simulation and density functional theory (DFT). Two DFT approaches, based on the homogeneous and inhomogeneous versions of Wertheim's first order perturbation ...

Embedding Properties of sets with finite box-counting dimension [PDF]

open access: yes, 2019
In this paper we study the regularity of embeddings of finite--dimensional subsets of Banach spaces into Euclidean spaces. In 1999, Hunt and Kaloshin [Nonlinearity 12 1263-1275] introduced the thickness exponent and proved an embedding theorem for ...

Coal Permeability Variation during the Heating Process considering Thermal Expansion and Desorption Shrinkage

open access: yesAdsorption Science & Technology, 2022
In order to explore the influence of coal deformation caused by temperature and desorption on seepage characteristics in the process of heat injection mining of coalbed methane, the permeability test, thermal expansion, and constant temperature ...

Optical properties of lowest-energy carbon allotropes from the first-principles calculations [PDF]

open access: yes, 2017
We study the optical properties of lowest-energy carbon allotropes in the infrared, visible and ultra-violet ranges of light in the general gradient approximation of the density functional theory.

Influence of the Heating Rate on the Foaming Behavior of Various Aluminium Alloys

open access: yesMetals, 2017
Powders of metallurgically prepared precursors expand to a foam differently depending on how fast they are heated to their foaming temperature. The foaming behavior of four alloys was studied with heating rates varying from 0.1 K/s to 18 K/s.

Comparative study on the evolution of fracture structure of bituminous coal based on different pyrolysis methods

open access: yesMeitan xuebao, 2023
Underground in-situ pyrolysis of coal is a new trend in the utilization of coal resources in the future. It is especially critical to investigate the coal pore-fissure structure, its spatial distribution and connectivity under different pyrolysis methods,
