Using density functional theory calculations and ab initio atomistic thermodynamics, H2O adsorption dissociation on the Fe(110) p(4 × 4) surface at different coverages have been computed. At lowest coverage, adsorbed H2O, OH, O H species can migrate easily surface. For (H2O)n adsorption, molecules donating atoms for H-bonding adsorb more strongly than those accepting H-bonding. Monomeric is favored both thermodynamically kinetically. On nO pre-covered surfaces (n = 1-8), accessible + 1-7)...
Water adsorption and dissociation on the Fe(100) surface at different coverages have been calculated using density functional theory methods ab initio thermodynamics. For of (H2O)n clusters (3 × 4) surface, energy is contributed by direct H2O–Fe interaction hydrogen bonding. n = 1–3, dominant, bonding becomes more important for 4–5. 6–8 12, structurally configurations very close energies. Monomeric H2O favored clean than that or OH precovered surfaces. O-assisted favorable kinetically (O +...
Spin-polarized density functional theory computations have been carried out to study the adsorption and dissociation of CO on clean as well nCu-adsorbed nCu-substituted Fe(100) surfaces (n = 1–3) at different coverage explore Cu promotion effect in activation. Increasing content not only lowers energies but also increases barriers making thermodynamically less favorable, surface is most active dissociation. The can suppress more strongly than surface. stretching frequencies coverages...
A tunable dynamic cross-linked polyurethane that makes a tradeoff between superior mechanical performance and excellent self-healing ability.
The dual-dynamic networks endow polyurethane with excellent mechanical properties and autonomous self-healing ability.
Abstract Passive cooling is a technology that does not require external energy input, with most passive strategies having high manufacturing difficulty and cost. In this study, we prepared lightweight aerogels (0.093 g/cm 3 ) porosity (91.3%), directional pores, enhanced elastic recovery performance, lower thermal conductivity (0.046 W/mK) through simple mixing, freezing, freeze‐drying. The samples have reflectance of 87% in the ultraviolet—visible—near‐infrared (UV‐Vis‐NIR) range (0.2–2.5...
The adsorption and co-adsorption of CO H2 at different coverage on the CdI2-antitype metallic Mo2C(001) surface termination have been systematically computed level periodic density functional theory. Only molecular is possible monolayer (1 ML) can 16CO adsorbed top sites. Dissociative favored thermodynamically 16H hollow Since has much stronger energy than H2, pre-adsorption possible. strongly affects atomic hydrogen a high CO/H2 ratio, while hardly that low ratio. Under ultra-high vacuum...
Abstract Passive cooling technology is currently a hot research topic because it can achieve without external energy input, significantly reduce costs and mitigate global warming. At present, passive mainly used in construction, transportation, electronic equipment, other fields, but most materials do not have gas barrier performance, which limits the application of inflatable structures such as film buildings, blimp bladders so material that has both performance needed. In this paper, P X...
Spin-polarized density functional theory computations have been carried out to investigate the adsorption configurations of Cun (n = 1–7, 13) on most stable Fe(110) and Fe3C(001) surfaces. On both surfaces adsorbed clusters favor aggregation over dispersion, monolayer are more favored thermodynamically than two-layer structures because stronger Fe–Cu interaction Cu–Cu bonding. basis computed energies surface has Cu affinity surface, in agreement with experimental results. The also pronounced...
The characteristics of the vibrations induced by passage a high-speed train do not only depend on speed, axle load, and track irregularity but also properties foundation soil surrounding topography. Estimating vibration in different terrains is therefore essential. This study investigates propagation attenuation trains loess-terraced slopes. influence mechanical analyzed through numerical simulation. Field experiments are conducted to measure at slope site Qin’an, Gansu, China. measured...
