Bioaccessibility of Metal(loid)s From Anthropogenic Contamination in Dry Riverbed Sediments in the Cartagena–La Unión Mining District (Murcia, SE Spain): Implications for Human Health Risk Assessment

Environmental Toxicology, EarlyView.
ABSTRACT This study assessed the contamination levels, bioaccessibility, and potential health risks of As, Cd, Cu, Pb, and Zn in sediments from three dry riverbeds (El Beal‐EB, Las Matildes‐LM, and Ponce‐PN) impacted by historical mining activities in the Cartagena‐La Unión Mining District.

Quantitative collagen and proteoglycan imaging reveal organic layering, gradients and regional texture in young mature dental cementum

VIEW, EarlyView.
Cementum, the mineralized tissue covering all mammalian tooth roots, helps maintain tooth stability, but its internal organization is still poorly understood. In this study, we combine quantitative histologial methods to map the regional distributions of collagen fibers and proteoglycan‐rich matrix layers in porcine cementum.

Polyaniline as a dual flame retardant and electrostatic dissipative additive in polyethylene nanocomposites

Journal of Vinyl and Additive Technology, Volume 31, Issue 2, Page 339-355, March 2025.
Effecft of co‐doping polyaniline with phosphoric acid and phytic acid on the heat release rate of polyethylene. Abstract Polyolefins, such as polyethylene (PE), are highly flammable and electrically insulative, limiting their applicability. The study explored the flame‐retardancy and electrical conductivity of PE/polyaniline (PE/PANI) nanocomposites ...

YK‐4‐250, a synthetic telmisartan–tempol conjugate: crystal structure of a stabilized free radical containing an angiotensin AT1 receptor inhibitor

Acta Crystallographica Section C, EarlyView.
The first crystal structure of the telmisartan–tempol conjugate YK‐4‐250 is reported, revealing the intramolecular C–H…π interactions that stabilize the nitroxide radical while preserving the angiotensin AT1 receptor antagonist pharmacophore.We report the first crystal structure of the telmisartan–tempol conjugate 2,2,6,6‐tetramethyl‐1‐(λ′‐oxidaneyl ...
