Pollution and Health Risk Assessments of Potentially Toxic Elements in the Fine-Grained Particles (10–63 µm and <10 µm) in Road Dust from Apia City, Samoa

open access: yesToxics, 2022
Fine road dust is a major source of potentially toxic elements (PTEs) pollution in urban environments, which adversely affects the atmospheric environment and public health. Two different sizes (10–63 and

Extreme‐Temperature Resistant, Flexible, and Sensitive Strain Sensor for Aerospace Parachute Deployment

open access: yesAdvanced Materials Technologies, EarlyView.
In this study, we report a resistive‐type strain sensor fabricated using single‐walled CNTs, are used layer using the pray technique to deposit as conductive, and UV‐resin was spin‐coated as a protection layer. The sensor functioned in harsh temperature variation conditions from −50°C to 125°C without deterioration.

Ultrafast (1‐5 sec) Lamination of Perovskite Solar Cells With Self‐Encapsulation Using Rapid Joule Heating

open access: yesAdvanced Materials Technologies, EarlyView.
Halide perovskite solar cells are fabricated with self‐encapsulation by lamination between two glass substrates using rapid Joule heating, yielding a 99% reduction in lamination time compared to previous studies. An 18% efficient cell is laminated in 5 s, demonstrating the potential for scalable manufacturing. ABSTRACT Perovskite solar cells (PSCs) are

Downward Movement of Potentially Toxic Elements in Biosolids Amended Soils

open access: yesApplied and Environmental Soil Science, 2012
Potentially toxic elements (PTEs) in soils are mainly associated with the solid phase, bound to the surface of solid components, or precipitated as minerals. For most PTEs, only a small portion is dissolved in the soil solution.

Factors on the distribution, migration, and leaching of potential toxic metals in the soil and risk assessment around the zinc smelter

open access: yesEcological Indicators, 2022
Mining activities usually caused soil polluted by potential toxic elements (PTEs). This paper used the analysis of correlation, variance, and power analysis to clarify the relationship and migration characteristic of 90 samples in 30 sampling points at ...

Oil‐Coated Nanoplastics Induce Rapid Membrane Disruption and Severe Intestinal Injury

open access: yesAdvanced Science, EarlyView.
Oil‐rich food contact dramatically amplifies MNP release from plastic takeout containers, producing oil‐coated nanoplastics with altered surface properties and rapid membrane‐disruptive effects. These particles cause severe intestinal barrier damage and immune dysfunction in mice, and risk modeling suggests that long‐term gastrointestinal burdens may ...

Improved Mapping of Potentially Toxic Elements in Soil via Integration of Multiple Data Sources and Various Geostatistical Methods

open access: yesRemote Sensing, 2020
Soil pollution by potentially toxic elements (PTEs) has become a core issue around the world. Knowledge of the spatial distribution of PTEs in soil is crucial for soil remediation.

Tunable Negative Thermal Expansion in Fe/Cr‐Substituted Nd2Co17 Compounds via Magnetoelastic Coupling

open access: yesAdvanced Science, EarlyView.
This study achieves anisotropic thermal expansion tuning in Nd2(Co1‐xFex)17‐yCry compounds via a magnetoelastic strategy. Variable‐temperature synchrotron X‐ray diffraction reveals that increased Fe content induces switchable lattice responses. Compositional control reduces the volume expansion coefficient αV by 20% (x═0.7) and modulates TC (442–625 K),
