Solvent‐Free Thermal Defect Engineering in Molecular Frameworks With Volatile Linkers

open access: yesAdvanced Materials, EarlyView.
Thermal removal of neutral volatile linkers enables precise and solvent‐free generation of metal vacancies in MOFs. This strategy affords redox‐stable, coordinatively unsaturated FeII sites with tunable spin, ligand coordination, and catalytic behavior. The approach offers a general route to design defect‐functional materials through local coordination

Neither agreement nor pronouns

open access: yesIsogloss
Baker & Kramer (2018) suggests that the distribution of clitic doubling in Spanish follows from Weak Crossover. Thus, the fact that in accusative clitic doubling bare wh-phrases cannot be doubled (e.g., *¿A quién lo viste?

Electronic polarons in an extended Falicov-Kimball model

open access: yes, 2005
We examine the one-dimensional spinless Falicov-Kimball model extended by a hybridization potential between the localized and itinerant electron states.

Assembling a True “Olympic Gel” From over 16 000 Combinatorial DNA Rings

open access: yesAdvanced Materials, EarlyView.
Olympic gels are an elusive class of soft matter, consisting of molecular networks held together purely by mechanically interlocked rings. Their topological structure promises unique properties and functions, but their synthesis has proven notoriously difficult.

Crossover Between Universality Classes in the Statistics of Rare Events in Disordered Conductors

open access: yes, 2001
The crossover from orthogonal to the unitary universality classes in the distribution of the anomalously localized states (ALS) in two-dimensional disordered conductors is traced as a function of magnetic field. We demonstrate that the microscopic origin

A Global Economy Analysis of Weak Crossover

open access: yesLinguistics in the Netherlands, 1994
Reinhart (1993a,b), developing work by Golan (1993), argues that this condition, the "shortest link" condition, should be relativized to interpretation. This relativization does not apply to all economy effects, such as the "skipped landingposition" condition or other economy conditions (cf.

Self‐Regulating Sodium‐Ion Battery Materials: From Phase Reconstruction to Functional Activation

open access: yesAdvanced Materials, EarlyView.
Self‐regulating sodium‐ion batteries hinge on programmable phase behavior in layered oxides, interphases that renew without growth, and electrolytes that steer solvation and chemistry. This review distills mechanisms into design rules that span composition, site and entropy tuning, and self‐buffering anodes, linking operando evidence to choices and ...

Semiclassical dynamics of a dark soliton in a one-dimensional bosonic superfluid in an optical lattice

open access: yesPhysical Review Research, 2020
We study quantum dynamics of a dark soliton in a one-dimensional Bose gas in an optical lattice within the truncated Wigner approximation. Previous work has revealed that in the absence of quantum fluctuations, dynamical stability of the dark soliton ...
