Exposure–Recovery Approach for Hepatic Toxicity Analysis of Pyrethroid Lambda‐Cyhalothrin: Histopathological, Histochemical, and Biochemical Responses in Oreochromis niloticus

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT Lambda‐cyhalothrin is a synthetic pyrethroid insecticide widely used in agriculture, but its potential to contaminate aquatic ecosystems and exert high toxicity on fish at low concentrations raises ecotoxicological concerns. While standard histopathological and biochemical assessments are common, the novel integration of pigment‐based ...

Ultra‐Fast and Energy‐Efficient PZT Optical Tunable Delay Lines for Programmable Photonic Systems

open access: yesLaser &Photonics Reviews, EarlyView.
Thin‐film PZT enables optical tunable delay lines that simultaneously offer sub‐nanosecond switching, low propagation loss, and zero‐static‐power programmability. A five‐bit on‐chip delay line provides a maximum delay of 387.5 ps with a resolution of 12.5 ps, while reconfigurable MZI splitting ratios further enable non‐volatile optical arbitrary ...

Prototypes of Highly Effective Stress Balancing AlN Interlayers in MOVPE GaN-on-Si (111)

open access: yesInorganics
The GaN-on-Si virtual substrate is now an indispensable platform for the application of GaN in the fields of power devices, radio frequency, light-emitting devices, etc. Such applications are still in need of more effective stress balancing techniques to

Interdiction Models and Heuristics for Graph Propagation

open access: yesNetworks, EarlyView.
ABSTRACT Given a graph G=(V,E)$$ G=\left(V,E\right) $$ and a set S⊂V$$ S\subset V $$ of activated/infected nodes, we consider the problem of determining the set of c$$ c $$ nodes that minimizes the network propagation on the subgraph that results from the removal of those c$$ c $$ nodes. To measure network propagation, we assume that a node i$$ i $$ is

Agricultural and environmental drivers of variation in the composition of food crops: A scoping review

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Agricultural management and environmental conditions influence the biochemical composition of food crops; however, the specific drivers of this variation remain insufficiently understood, despite their importance for climate change adaptation and human health.

Thermal Instability Pathways of Aluminum‐Based Nanocomposites: The Role of Alloying‐Element‐Driven Precipitation and Amorphous Interlayers

open access: yesSmall, EarlyView.
Thermal instability mechanisms governing novel Al‐based PVD/ALD nanocomposites are uncovered through synchrotron XRD, STEM, APT, and micromechanical testing. Temperature‐dependent crystallite evolution reveals a defined stability window before degradation dominates, offering new insight into the design of thermally robust, functional Al‐based ...

Preserving Hierarchical Integrity During Primary Structure Modification of Spherulitic MOFs

open access: yesSmall, EarlyView.
A MOF‐74‐type zinc framework self‐organizes into well‐defined spherulitic superstructures while allowing precise covalent post‐synthetic modification (PSM) of the linkers. A built‐in tetrazine enables fast inverse electron‐demand Diels–Alder (iEDDA) functionalization to uniformly install primary amines.

Characterization of Nonmetallic Inclusions in Ce‐Containing Steels at the Submicroscopic Level

open access: yessteel research international, EarlyView.
Accurate detection of nonmetallic inclusions (NMIs) is crucial for ensuring high standards in steel cleanness and properties. Optimized automated SEM/EDS measurements are required for evaluating Ce‐containing NMIs. This study enhances the characterization of submicroscopic NMI in Ce‐alloyed ultralow‐carbon, high‐manganese, and electrical steels ...
