Social, Technological, Economic, and Policy Factors in the Circular Economy Transition in Brazil

open access: yesSustainable Development, EarlyView.
ABSTRACT A well‐functioning circular economy (CE) integrates resilience across economic, environmental, and social dimensions. This study identifies key drivers and barriers to Brazil's CE transition through 20 semi‐structured interviews with stakeholders. Major sociocultural barriers include inadequate education and limited CE awareness, while growing

Covalent Functionalization of NiFe Layered Double Hydroxides using Tris(Hydroxymethyl)Aminomethane

open access: yesSmall, EarlyView.
Covalent functionalization of NiFe layered double hydroxides with tris(hydroxymethyl)aminomethane enables controlled growth, enhanced structural order, and improved processability. Temporary TRIS anchoring promotes stable water‐based inks and binder‐free electrode fabrication, leading to enhanced oxygen evolution activity and long‐term stability under ...

Unlocking Nanoscale Microstructural Detail in Aluminum Alloys Through Differential Phase Contrast Segmentation in STEM

open access: yesSmall Methods, EarlyView.
Differential phase contrast (DPC) imaging in STEM is demonstrated as a rapid, versatile segmentation tool for advanced aluminum alloys. Decomposition of false‐color DPC micrographs resolves nanoclusters, precipitate variants, dislocation strain fields, nanostructures, and grain boundaries ‐ all within a single and fast acquisition.

Analysis of the influence of supplementary reinforcement on the behavior of reinforced‐concrete two‐pile caps subjected to concentric and eccentric loading

open access: yesStructural Concrete, EarlyView.
Abstract This article examines the behavior of reinforced‐concrete pile caps on two piles under concentric and eccentric loading, with emphasis on the influence of horizontal and vertical supplementary reinforcement on load‐carrying capacity. Although the Strut‐and‐Tie method does not include this reinforcement in the internal equilibrium, it was found

Agricultural Fungicide Mancozeb in Leaf Litter Enhances Survival and Growth of Aedes aegypti (Diptera: Culicidae)

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Mancozeb is one of the most widely used agricultural fungicides, exhibiting strong efficacy against a broad spectrum of phytopathogenic fungi. However, its widespread application comes at the cost of environmental contamination. Here, we show the effects of Inga vera leaf litter contamination with Mancozeb on life‐history traits of Aedes ...

The effect of seawater hardness on cotton fabric dyeing using reactive blue dye

open access: yesColoration Technology, EarlyView.
Abstract Oceans are an abundant source of water; their economic potential has not yet been fully exploited. In this context, the current study aims to apply seawater in the dyeing of cotton fabrics, evaluating the influence that total hardness has on the process results.

Effects of repeated exposure to ozonated water on hair fibre structure and integrity: Part I

open access: yesInternational Journal of Cosmetic Science, EarlyView.
Repeated exposure to ozonated water caused cumulative oxidative changes in hair, altering structural integrity, thermal behaviour and mechanical properties. The findings reveal a distinct ozone‐induced damage profile that progresses beyond the cuticle, challenging claims of hair‐revitalizing benefits. Abstract Objective Ozone has recently been marketed
