Per- and poly-fluoroalkyl substances (PFAS) are chemicals of concern—they are ubiquitous, persistent, with known and suspected health impacts. Well studied, primary sources of exposure to PFAS are drinking water and food. The presence of PFAS in human tissue of general populations suggests other important exposure sources/pathways. House dust measurements suggest widespread presence of PFAS in residences

A recent correspondence (Öberg, 2024) about our manuscript, Tampons as a source of exposure to metal(loid)s (Shearston et al., 2024), highlights the importance of data for complete risk assessment and public health communication when data gaps exist. Our study, which measured the concentration of 16 metals in tampons, detected the toxic metals lead (Pb), arsenic (As), and cadmium (Cd). Our study was

There is a body of evidence that ultrafine particles (UFP, those with diameters ≤ 100 nm) might have significant impacts on health. Accordingly, identifying sources of UFP is essential to develop abatement policies. This study focuses on urban Europe, and aims at identifying sources and quantifying their contributions to particle number size distribution (PNSD) using receptor modelling (Positive Matrix

BackgroundPrenatal per- and polyfluoroalkyl substance (PFAS) exposures are associated with adverse offspring health outcomes, yet the underlying pathological mechanisms are unclear. Cord blood metabolomics can identify potentially important pathways associated with prenatal PFAS exposures, providing mechanistic insights that may help explain the long-term health effects. MethodsThe study included 590

Efficient recovery of palladium (Pd) from waste sources is of paramount importance due to its limited natural reserves and potential environmental hazards. Herein, a carbon sorbent, namely sulfur-functionalized porous carbon microsphere (SPCM), was used to selectively capture Pd(II) from acidic solution. SPCM exhibited high efficiency for the adsorption separation of Pd(II) from 0.5 M to 6 M HNO3 solution

Suppressing energy/voltage loss and realizing efficient charge transfer at small frontier molecular orbital offsets between donor and acceptor is viable to simultaneously improve open-circuit voltage (Voc) and short-circuit current (Jsc), and thus power conversion efficiency (PCE) of organic solar cells (OSCs). Here, two A-DA’D-A type acceptors, PEH-F and TEH-F, are designed and synthesized with different

In recent years, high-entropy methods have garnered significant attention in the field of energy-storage applications, particularly in rechargeable batteries. Specifically, they can impart materials with unique structures and customized properties, thereby showcasing new attributes and application potential. In this review, we describe the various influences that the high-entropy concept exert on electrochemical

Aqueous zinc ion batteries (AZIBs) present a transformative avenue in electrochemical energy storage technologies, leveraging zinc anodes and aqueous electrolytes for safety and cost-effectiveness. The primary challenge of mitigating zinc dendrite formation in these batteries is addressed through electrolyte strategies, focusing on reducing water activities. Despite advancements in extending cycle

All-polymer solar cells (all-PSCs) are thought to be the most promising candidate for the practical application of organic solar cells (OSCs). However, the efficiencies of all-PSCs remains lower than those of small molecule acceptor (SMA)-based OSCs due to their unfavorable active-layer morphology. The complicated molecular interaction and aggregation behavior involved in all-polymer blends make it

Managing iodine formation is crucial for realising efficient and stable perovskite photovoltaics. Poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) is a widely adopted hole transport material, particularly for perovskite solar cells (PSCs). However, Improving the performance and stability of PEDOT:PSS based perovskite optoelectronics remains a key challenge. We show that amine-containing

Unravelling the volcanic history of the enigmatic lunar farside is essential for understanding the hemispheric dichotomy of the Moon1-3. Cratering chronology established for the lunar nearside has been used to suggest long-lived volcanism on the farside of the Moon3,4, but without sample verification. Here we report two newly recognized episodes of basaltic volcanism with Pb-Pb dating for basalt fragments

Despite recent advances in mammalian synthetic biology, there remains a lack of modular synthetic receptors that can robustly respond to soluble ligands and in turn activate bespoke cellular functions. Such receptors would have extensive clinical potential to regulate the activity of engineered therapeutic cells, but to date only receptors against cell surface targets have approached clinical translation1
