Stoichiometric Binding of Cyclophilin‐A to The HIV‐1 Capsid Modulates Its Mechanoelastic Properties

Small, EarlyView.
The HIV‐1 capsid is a protein nanocapsule that must balance rigidity and flexibility to enter the cell nucleus. Atomic force microscopy simulations reveal that binding of the host protein Cyclophilin A tunes this mechanical response: partial coverage preserves deformability, while excessive binding induces brittleness and failure.

A Dynamic Surface Metal‐Organic Framework Electrocatalyst: Potential‐Driven Activation of Atomically Defined Au Sites for the Hydrogen Evolution Reaction

Small, EarlyView.
Operando EC‐STM reveals that an NHC‐based SMOF on Au(111), initially frozen in interconnected 1D chains, dynamically reconfigures under cathodic bias into a fluxional structure bearing undercoordinated Au sites while abstracting Au atoms from the support.

A Polar Topology Network Induces Elastic Stiffening in Ferroelectric Oxide Superlattices

Small, EarlyView.
The periodicity in BiFeO3/SrTiO3 superlattices tunes the system into a dense, elastically constrained polar texture state. This topology‐rich regime reveals a collective mechanical response in which interactions among polar topological defects restrict local deformations, producing a pronounced elastic stiffening.

Atomic‐Scale Control of Substrate‐Spin Coupling Via Vertical Manipulation of a 2D Metal‐Organic Framework

Small, EarlyView.
A slightly buckled 2D kagome metal‐organic framework (MOF) adsorbed on Ag(111) hosts localized spins which are Kondo‐screened by the underlying metal substrate. Using the tip of a scanning tunneling microscope, the MOF can be vertically manipulated to controllably change its adsorption height and with it, the Kondo coupling strength.
