Interferometric Vector Piezoresponse Force Microscopy for Simultaneous Ferroelectric Domain and Crystallographic Orientation Mapping in Uniaxial Ferroelectric Polycrystals

Small, EarlyView.
Interferometric vector piezoresponse force microscopy is used to reconstruct crystallographic grain orientations in polycrystalline ferroelectrics directly from local electromechanical response. The approach reveals grain orientation, polarization direction, and domain structure simultaneously, establishing a pathway toward EBSD‐like orientation ...

HS‐AFM Reveals Hierarchical RNA Folding Driving Condensate Assembly and Material States

Small, EarlyView.
High‐speed atomic force microscopy reveals the nanoscale pathway of RNA condensate formation, from individual RNA folding to higher‐order assembly. Quantitative analyses of fusion dynamics and nanomechanical properties distinguish liquid‐like poly A condensates from solid‐like total RNA assemblies, providing a direct link between RNA self‐assembly and ...

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 ...

How We Simulate Nanopores

Small Methods, EarlyView.
Nanopore technology has revolutionized single‐molecule sensing, yet it suffers from an inherent interpretive challenge. Molecular dynamics has emerged as a go‐to method for determining the relationship between the structure of translocating molecules and the nanopore current signals.

Impact of Plasma Ashing on Mixed Monolayer Doping of Silicon

Small Methods, EarlyView.
Mixed monolayer doping provides a controllable way to introduce phosphorus dopants into silicon. A gentle oxygen‐plasma treatment removes unwanted carbon while maintaining phosphorus on the surface. Following thermal diffusion, the treated silicon shows enhanced near‐surface n‐type behavior, demonstrating how carbon removal can tune molecular doping ...

Experimental and design‐oriented research on fiber reinforced concrete segmental tunnel linings: A systematic review

Structural Concrete, EarlyView.
Abstract The use of fiber reinforced concrete (FRC) in precast tunnel segments is among the most established and representative applications of this material. Over the past two decades, numerous tunnel linings were constructed with partial or total substitution of conventional steel reinforcement by fibers, this yielding to quantifiable benefits in ...

Sensitivity study on accuracy and relevant parameters in numerical modeling of internal tendon breaks

Structural Concrete, EarlyView.
Abstract This study investigates the numerical modeling of internal tendon breaks in prestressed concrete structures and evaluates the key parameters affecting accuracy. A combined approach is followed, involving global sensitivity analysis via the Elementary Effects Method and subsequent model calibration using experimental data from distributed fiber‐
