Responses of primary producers, anoxia, and chemical feedback to Late Glacial climate change: Insights from a paired lake approach

Journal of Quaternary Science, EarlyView.
Abstract Worldwide, lacustrine ecosystems are threatened by eutrophication and deoxygenation. Both processes are driven by the combined effects of human activities and climate change. Understanding the pre‐anthropogenic nexus between warming, eutrophication, deoxygenation, and related feedback is essential to determine how lakes respond to rapid ...

Efficient and Tunable Narrowband Second‐Harmonic Generation by a Large‐Area Etchless Lithium Niobate Metasurface

Laser &Photonics Reviews, EarlyView.
An etchless lithium niobate (LN) metasurface with a slanted periodic TiO2 grating enables efficient and narrowband second‐harmonic generation (SHG) thanks to the light confinement in the LN film granted by quasi‐bound‐state‐in‐the‐continuum (q‐BIC) modes.

Nature of Surface Microcracks on Phosphorus Micro‐Alloyed Copper

Materials and Corrosion, EarlyView.
SSRT tests and microscopic characterization methods were used to study the effect of plastic deformation and environment on the formation of surface microcracks on Cu‐OFP. Results show that, while ambient conditions produced thousands of microcracks per mm2, exposure to sulfide water resulted in fewer microcracks with no evidence of crack growth ...

Guidelines for Meta‐Analytic Structural Equation Modeling: Steps, Resources, and Illustrations

Psychology &Marketing, EarlyView.
ABSTRACT The goal of science is to build incremental, structured, and reliable knowledge over time. Yet, many strands of marketing and related disciplines exhibit symptoms of cumulative stagnation, including lack of replicability and weak theoretical integration. Existing remedies such as replication studies, multistudy investigations, and open science

How can children and young people have a voice in urban treescapes?

People and Nature, EarlyView.
Abstract Scientific understanding of climate change has, to date, failed to result in sufficient action. This paper proposes that a deficit model of top‐down learning and dissemination in relation to public engagement with science may be part of the problem, particularly when considering the attitudes, values and empowerment of children and young ...

Combined Effects of Thermal Cycling Aging and Reinforcement Content on the Ball‐On‐Disk Wear of Additively Manufactured Polylactic Acid Composites

Polymer Composites, EarlyView.
Thermal Aging and Tribological Tests of Additive Manufactured PLA Composites. ABSTRACT This study focuses on the additive manufacturing of pure polylactic acid (PLA) specimens and milled glass fiber (GF)‐filled PLA composites under thermal cycling aging and wear tests. Wear tracks have been analyzed via 3D optical profiling and SEM imaging.

Piper nigrum Has an Antitumor Effect Through Regulation of the Phosphatidylinositol 3‐Kinase Signaling Pathway in a Murine Model of Acute Myeloid Leukemia

Phytotherapy Research, EarlyView.
Overview of the antileukemic effects of Piper nigrum extract in AML. P. nigrum reduced leukemic cell proliferation and glycolytic metabolism through modulation of the PI3K/AKT/mTOR pathway. In vivo, treatment reduced leukemic burden, improved hematological parameters, prolonged survival, and modulated antitumor immune responses.

Osmotic Remodeling of Extracellular Vesicles for Precision Nanomedicine

Small, EarlyView.
Hypotonic lysis in bidistilled water is used to remodel B lymphocyte–derived extracellular vesicles into cargo‐depleted, structurally preserved nanovesicles. The process reduces intraluminal proteins and nucleic acids, reshapes membrane composition, and enhances tumor‐cell uptake in vitro, while allowing proof‐of‐concept reloading with exogenous agents,

Electrocatalytically Amplified Immunosensing Enabled by Titanium Oxynitride‐Supported Ru Nanodots on Graphene Oxide Hybrid Architecture

Small, EarlyView.
A synergistic effect among the electrocatalytic Ru/TiON‐GO nanocomposite, biorecognition elements, and the [Fe(CN)6]3−/4− redox probe for highly sensitive and selective impedimetric detection of PSA protein in human serum was demonstrated. The immunosensor exhibited a limit of detection of only 0.06 ng mL−1 PSA protein, underscoring the importance and ...
