Exposure-Integrated Risk Prioritization of Legacy and Emerging PFAS: A Case Study of a Major River Basin in South Korea via High-Resolution Mass Spectrometry

This study pioneers an exposure-integrated risk prioritization framework for the Geum River basin in South Korea by combining high-resolution mass spectrometry with QSAR-based hazard assessment, revealing that while long-chain PFAS possess the highest intrinsic toxicity, short-chain variants like PFBS and PFHxA along with PFOA constitute the greatest management priority due to their widespread environmental loading.

Synthesis of a superabsorbent with low residual monomer content by gamma irradiation and improving gel strength through surface treatment

This study demonstrates that gamma irradiation can efficiently synthesize acrylic acid superabsorbents with negligible residual monomers, while subsequent surface cross-linking with DEGDGE significantly enhances gel strength and absorption under load, making the material ideal for hygiene and biomedical applications.

Anisotropy in thermoelectric properties of textured ZnSb nanomaterial by high Zn occupancy (132) crystallographic planes

This study reports the cost-effective synthesis of textured ZnSb nanomaterials via spark plasma sintering, revealing that anisotropic thermoelectric properties arise from preferential crystallographic orientations where higher Zn occupancy on (132) planes enhances the Seebeck coefficient while electrical conductivity is maximized along the (211) planes.
