Adsorption and Separation by Flexible MOFs

open access: yesAdvanced Materials, EarlyView.
Flexible metal–organic frameworks (MOFs) present significant potential for gas storage and separation due to their structural dynamic. This review explores the rationale behind the flexible MOFs' enhanced working capacity and separation factors. It also addresses key challenges, including phase transition kinetics, crystal robustness, cycling, shaping,

Manipulating Ferroelectric Topological Polar Structures with Twisted Light

open access: yesAdvanced Materials, EarlyView.
We demonstrate dynamic control of ferroelectric order in quasi‐2D CsBiNb2O7 using twisted ultraviolet light carrying orbital angular momentum. Our approach harnesses non‐resonant multiphoton absorption and induced strain to modulate topological of ferroelectric polarization textures.

State‐of‐the‐Art, Insights, and Perspectives for MOFs‐Nanocomposites and MOF‐Derived (Nano)Materials

open access: yesAdvanced Materials, EarlyView.
Different approaches to MOF‐NP composite formation, such as ship‐in‐a‐bottle, bottle‐around‐the‐ship and in situ one‐step synthesis, are used. Owing to synergistic effects, the advantageous features of the components of the composites are beneficially combined, and their individual drawbacks are mitigated.

Iodine‐Doped Sodium Vanadate Cathode for Improved Zn Ion Diffusion Kinetics

open access: yesAdvanced Materials, EarlyView.
An iodine‐doping strategy is developed to modify the Na2V6O16·3H2O cathode for aqueous zinc‐ion batteries, effectively reducing the electrostatic interaction between zinc ions and the host structure. This modification enables faster diffusion and higher storage capacity of zinc ions. Abstract The electrostatic interaction between zinc ions and the host

The impurity-impurity interaction in aluminum

Physics Letters A, 1973
Abstract The interaction between a Cu atom and a Sn atom in aluminum was calculated by the pseudopotential method. It is shown that there is a rather weak coupling between these different types of impurity atoms.

Theory of impurity scattering: Interstitial impurities [PDF]

open access: possiblePhysics of Condensed Matter, 1975
A framework for studying impurity scattering in dilute, non-magnetic, metal alloys can be developed from a knowledge of the exact electronic eigenstates of a single impurity in an otherwise perfect lattice of muffin tin potentials. Such an approach has been developed for systems in which the impurity occupies a substitutional site of the lattice, as ...

Vacancy-vacancy, vacancy-impurity, and impurity-impurity interactions in aluminum

Physical Review B, 1974
Electronic interactions between vacancies and impurity atoms have been generally studied using the pseudopotential formulation based on the second-order perturbation theory. The distortions of the lattice around vacancies and impurity atoms were conventionally neglected because of their great complexity.

Impurities in graphene

physica status solidi (a), 2010
AbstractWe report the transport properties of graphene in the presence of topological and (non‐topological) long‐range impurities, in the framework of a tight‐binding model. We first investigate the electronic transport properties of a zigzag edge graphene nanoribbon with several kinds topological defects: a pentagon, a heptagon, and a pentagon ...
