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 ...

Bioactive Gold Plasmonic Interfaces Meet Artificial Intelligence: Advancing Saliva‐Based Surface‐Enhanced Raman Spectroscopy Diagnostics

Small, EarlyView.
ABSTRACT Bioactive gold plasmonic nanostructures are enabling non‐invasive saliva diagnostics by amplifying weak Raman signals and converting complex biofluid chemistry into information‐rich spectral fingerprints. This Review examines saliva‐based Raman and surface‐enhanced Raman spectroscopy (SERS) integrated with artificial intelligence (AI) from a ...

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 ...

Simple and detailed modeling of corrosion‐affected slender shear critical RC beams

Structural Concrete, EarlyView.
Abstract The corrosion of steel bars compromises both the safety and the serviceability of reinforced concrete (RC) structures. Consequently, reliable tools are required to estimate the detrimental effects of corrosion on the structural response of RC members subjected to transverse loads.

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‐

The public agglomeration effect: Urban–rural divisions in government efficiency and political preferences

American Journal of Political Science, EarlyView.
Abstract Why and when do cities vote for the left? The emergence of the urban–rural divide in the United States in the 1930s is inconsistent with canonical theories of cleavages. This paper introduces an explanation: agglomeration effects. The provision of government services is more efficient in urban environments because of nonrivalries, economies of

From Model to Practice: Testing Near‐Infrared Spectroscopy as a Bone Collagen Prescreening Tool

Archaeometry, EarlyView.
ABSTRACT Collagen is a vital archaeological material, preserving biochemical signatures that provide insights into past environments, diets, and human–animal interactions. However, diagenetic processes can lead to rapid and often inconspicuous degradation of collagen. Given the variability in collagen preservation and its significance for analyses such

The bread of Toledo: Prices and political economy, 1535–1800

The Economic History Review, EarlyView.
Abstract We study the market for common white bread in the city of Toledo through a new 266‐year‐long series of bread prices, obtained from the cash purchases and wholesale bread‐for‐wheat contracts of large institutions. Our data are strongly consistent with fragmentary evidence on retail price regulation, as well as with shorter series from other ...
