The recovery of rare earth elements (REEs) from acidic wastewater is crucial to sustainable development, industrial processes, and human health. In this research, β-cyclodextrin-based nanosponges (β-CD/PVA-SA NSs) have been proposed as potential adsorbents for europium (Eu), dysprosium (Dy), gadolinium (Gd) recovery. are synthesized by cross-linking β-cyclodextrin (β-CD) functionalized polyvinyl alcohol (PVA) sodium alginate (SA). Experimental results indicate that β-CD/PVA-SA NSs exhibit favorable selectivity Eu, Dy, Gd, with the maximum adsorption capacity 222, 217, 204 mg/g, respectively, in addition stability cyclicity. maintain selective effects towards RE ions present mine drainage (AMD), thereby highlighting their practical applications. Furthermore, density functional theory (DFT) simulations unveiled fundamental interactions between groups anchored REEs, providing vital insights into mechanism. Hence, utilization has advance initiatives remediating water pollution facilitating recycling resources.

Abstract The wide range of pressure detection and the exceptional linearity are essential performance parameters for flexible sensors, enabling them to adapt diverse scenarios acquire information accurately. However, currently available “ultra‐wide range” piezoresistive sensors lack an optimal solution that effectively balances sensing properties, device thickness, process cost. This study proposes a distinctive approach by introducing Janus conductive structure assembled with dual resistive sensitive layers. design allows pressure‐induced staged transformation current transport path, mitigating variations saturation in sensor resistance over range. resulting demonstrates unprecedented 0–3800 kPa, showcasing remarkable sensitivity 4.11 kPa −1 outstanding 99.9% within 0–1000 kPa. Additionally, boasts thickness only ≈200 µm, made possible through utilization cellulose nanofibers material matrix. These achievements stand at forefront when compared existing reports. research explores potential applications these extended arrays domains human health motion monitoring. It investigates their utility gait analysis assisted posture correction, as well assessment rehabilitation instability.

The increasing utilization of X-rays has generated a growing need for efficient shielding materials. However, the existing Pb-based materials suffer from narrow X-ray absorbing range, high weight, and rigidity. Inspired by natural leaf, which can efficiently absorb light through chlorophyll carotenoids in confined cells, we engineer ultralight superelastic nanofibrous Bi2O3/Gd2O3 meta-aerogels (BGAs) with nanotrap arrays manipulating 3D assembly 1D Bi2O3 Gd2O3 nanofibers. BGAs synergistically photons complementary energy ranges into nanotraps induce cyclic collisions nanofibers, maximizing effective attenuation. meta-aerogel exhibits integrated performance efficiency (60-83%, 16-90 keV), ultralow density (10 mg cm-3), superelasticity. production these presents an avenue development next-generation protective resolution imaging systems.
