Defect Engineering in Large‐Scale CVD‐Grown Hexagonal Boron Nitride: Formation, Spectroscopy, and Spin Relaxation Dynamics

open access: yesSmall, EarlyView.
The controlled formation of defects in large‐area CVD‐grown hBN using various irradiation methods is demonstrated. Defect type and properties depend on particle type (He+, Ne+, Ar+, neutrons, and electrons), substrate effects, and film thickness.

Discrimination of Tryptophan Enantiomers at Sub‐pm Level by Multiparametric Analysis of a Label‐Free Organic Immunosensor

open access: yesSmall Methods, EarlyView.
Multiparametric analysis is a crucial aspect for enhancing the final sensitivity of biosensors based on organic transistors. The traditional approaches to treat the experimental data are not always suitable to extract the correct response. In this work EGOT characteristics are processed to achieve enantiodiscrimination of free Tryptophan enantiomers ...

3D Customized Silica‐Based AFM Probes Fabricated by Selective Laser Etching

open access: yesSmall Methods, EarlyView.
Selective laser etching (SLE) enables the monolithic fabrication of customized, fully 3D silica AFM probes integrating both cantilever and tip with controlled 3D geometries. The process allows the production of either sharp or spherical tips with high design flexibility, reproducibility, and yield.

High Power Density for All‐Fe2VAl‐based Thermoelectric Module by Enhancing the Power Factor of p‐type Leg Through Defect‐Engineering and Wetting Effect

open access: yesSmall Methods, EarlyView.
ABSTRACT The high thermoelectric performance of Fe2VAl stems from its sharply rising band edges on either side of the band gap, which is highly sensitive to composition. Addressing reproducibility and scale‐up challenges, we have developed a strategy to enhance its p‐type thermoelectric performance by defects and grain boundary engineering through ...

A Systemic Reflection On Why Biology Is Best : E(s) ∞$$ \infty $$ mc2 Sentience, Consciousness and Transcendance?

open access: yesSystems Research and Behavioral Science, EarlyView.
ABSTRACT The short essay makes a case that a post biological world will be a devolution. Sentience is a relational process linked with the awe and wonder we experience in relation to one another and our shared habitat. The voiceless need to be protected by extending solidarity on the basis of sentience—a normative plea, but also on the basis of ...

Influence of Competitive C–P Segregation on Austenite Grain Growth in Iron Alloys

open access: yessteel research international, EarlyView.
This study investigates how carbon influences phosphorus‐induced solute drag effects during isothermal annealing of austenite grain growth in Fe–C–P alloys. Using in situ high‐temperature laser scanning confocal microscopy and density functional theory simulations, it demonstrates that carbon above a critical temperature significantly reduces P ...

Calibration of equivalent geometric imperfections for second‐order theory analysis of hot‐rolled U‐profiles

open access: yesSteel Construction, EarlyView.
Abstract The stability behaviour of steel structures is important when performing design. Standards (such as EN 1993‐1‐1 – Eurocode 3 Part 1‐1) take the stability of steel members into account and allow for verifications using reduction factors or by second‐order theory analysis considering equivalent geometric imperfections.

The Pier Luigi Nervi's concrete structure of Palazzetto dello Sport: Modeling and dynamic characterization

open access: yesStructural Concrete, EarlyView.
Abstract This paper presents a numerical and experimental study aimed at the modeling and dynamic characterization of the reinforced concrete structure of the Palazzetto dello Sport in Rome, designed and by Pier Luigi Nervi with Annibale Vitellozzi, and built by Nervi & Bartoli contractors in 1956‐57.
