Record‐Low Compressibility in [N(C2H5)3CH3]FeCl4 Expands Phase Engineering Horizons in Hybrid Molecular Ferroelectrics

Small, EarlyView.
High‐pressure studies of the lead‐free hybrid organic–inorganic ferroelectric [N(C2H5)3CH3]FeCl4 demonstrate record low compressibility, establishing it as the least compressible molecular ferroelectric known. In situ diamond anvil cell experiments identify halide selection and inorganic sublattice tuning as key compressibility controls, advancing ...

Long-period gratings in chalcogenide fibers

, 2010
Les verres chalcogénures sont des matériaux optiques connus depuis 50 ans. Ils sont fortement non-linéaires, transparents dans l'infrarouge et photosensibles à la lumière visible. Grâce à des percées récentes du côté des procédés de fabrication, leurs applications dans divers domaines sont devenus possibles, notamment dans les capteurs biochimiques, le

A flexible arched artificial photoreceptor constructed by photodeformable liquid crystal polymers and its application in vision restoration

Smart Molecules, EarlyView.
A flexible arched artificial photoreceptor with high stability and biocompatibility was fabricated by integrating liquid crystal polymers with polyvinylidene fluoride‐trifluoroethylene. This device exhibits robust photoelectric responses under low‐intensity illumination and demonstrates efficacy in restoring visual responses in blind rats following ...

Dimensional stability and water transport behavior of concrete with high contents of wind‐turbine blade waste

Structural Concrete, EarlyView.
Abstract Fiber addition is a common strategy to enhance concrete's durability, avoiding cracks and reducing penetration of harmful agents. In this research, a sustainable fiber‐like material obtained from mechanical recycling of dismantled wind‐turbine blades and made up of glass fiber‐reinforced polymer (GFRP) fibers and microfibers, balsa wood, and ...

Evaluation of prestress losses in concrete beams using destructive and non‐destructive methods

Structural Concrete, EarlyView.
Abstract Over the past few decades, prestressing techniques have become essential in the construction of key structures, infrastructure, and bridges. The serviceability and safety of prestressed concrete (PC) elements are closely tied to the effectiveness of the prestressing process.

Ungulate substrate use in fauna passages

Wildlife Biology, EarlyView.
Fauna passages are increasingly constructed at major roads and railways to mitigate the negative effects of infrastructure and traffic on wildlife. The function of such passages depends on design, including the construction materials, soil, and vegetation.

Breakdown and Discharge Characteristics of High Repetition Frequency Nanosecond Pulsed Air Dielectric Barrier Discharge

High Voltage, EarlyView.
ABSTRACT This study explores the breakdown characteristics and discharge modes in a parallel plate air dielectric barrier discharge system using repetitive nanosecond pulses, with pulse repetition frequencies (PRFs) from 0.1 to 100 kHz. It examines how pulse parameters—PRF, pulse number and gas pressure—affect the memory effect, leveraging current and ...
