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.

NanoDMA and Nanoscratch Study of (Visco)‐Elastic and Plastic Behaviors of a Thin Film of a Molecular Spin Crossover Complex

Small, EarlyView.
Thin films of a molecular spin crossover complex are investigated across its thermally induced spin transition using quasi‐static and dynamic indentation techniques as well as nanoscratch experiments. When going from the low‐spin to the high‐spin state a sudden drop of elastic modulus is observed, but only a weak modulus relaxation occurs at the ...

The First Electrochemical Cycle: State‐of‐Charge Dependent Formation and Evolution of the Solid Electrolyte Interphase on Hard Carbon Anodes in Sodium‐Ion Batteries

Small Methods, EarlyView.
The formation and evolution of the solid electrolyte interphase on hard carbon electrodes is tracked at defined states of charge during the first galvanostatic cycle in sodium half‐cells. Combining SEM/EDS, XPS, ToF‐SIMS, SECM, and c‐AFM reveals how the SEI's morphology, chemistry, and interfacial reactivity develop during sodiation and partially ...

Strain-voltage and current-voltage Scanning Probe Microscopy (SPM) response of ionic semiconductor thin films: probing of deformation potential

, 2010
We performed analytical calculations of the current-voltage and strain-voltage response of the heterostructure like "charged SPM tip electrode / gap / ionic-semiconductor film" caused by the local changes of (a) ions concentration (stoichiometry contribution); (b) acceptors (donors) charge state (recharging contribution via ionic radius variation); (c)

Resonance‐Enhanced Four‐Wave Mixing Imaging for Mapping Defect Regions in Vanadium‐Doped WS2 Monolayers

Small Methods, EarlyView.
Resonant four‐wave mixing (FWM) microscopy reveals a spatial modulation of the third‐order nonlinear optical response in vanadium‐doped WS2 monolayers. This robust nonlinear contrast technique tracks the preferential accumulation of vanadium dopants along the structural bisection lines of the synthesized flakes.

Peptide Fingerprinting of Single Protein Molecules Using In‐Plane Nanopore Sensors Integrated to an Extended Immobilized Nanoscale Enzymatic Reactor (eINER)

Small Methods, EarlyView.
The protein Time‐of‐Flight (P‐ToF) chip can peptide fingerprint a single protein molecule by subjecting it to a solid phase endopeptidase cleavage reaction in‐line with a combination of resistive pulse sensing of the resulting single peptides and machine‐learning aided identification.
