Unlocking Solid Polymer Electrolytes: Advancing Materials through Characterization-Driven Insights.

JACS Au

August 2025

Centro de Física de Materiales (CFM-MPC), CSIC-UPV/EHU, 20018 Donostia - San Sebastián, Spain.

Solid polymer electrolytes (SPEs) hold great promise for next-generation battery technologies due to their inherent safety and mechanical stability. However, widely used poly-(ethylene oxide) (PEO)-based electrolytes face significant challenges, including high crystallinity, low ionic conductivity at ambient temperatures, and a narrow electrochemical stability window. Overcoming these limitations requires the development of novel polymer matrices alongside the refinement of advanced characterization methods that capture the fundamental dynamics of ion transport and polymer segmental mobility.

Protracted exposure to 134Cs and 137Cs gives substantial contribution to long-term thyroid absorbed dose after nuclear power plant accidents.

Radiat Prot Dosimetry

August 2025

Occupational and Environmental Medicine, Department of Medical Sciences, University of Uppsala, Akademiska Sjukhuset, 751 85 Uppsala, Sweden.

Thyroid dose estimations after nuclear power plant (NPP) accidents are traditionally based on internal uptake of radioiodine, mainly 131I, either by instrumental measurements of thyroid uptake or by ecological estimations based on geographical dispersion of the radioiodine cloud, demographics, and food habits. However, it has been shown that 134Cs and 137Cs in some cases can be the dominant contributors to the thyroid dose over long time following NPP accidents. Based on an ecological model using Swedish-specific parameters of the radioactive fallout from the Chernobyl accident in 1986, estimations of the protracted (30 years) thyroid absorbed dose were made for the population in northern Sweden (2.

Cardiovascular disease (CVD) remains the leading global cause of morbidity and mortality, largely driven by atherosclerosis, a chronic inflammatory process involving lipids and immune cells. Although traditional lipid biomarkers such as low-density lipoprotein (LDL) and high-density lipoprotein (HDL) are well-established in CVD risk stratification, the interplay between cytokines, chemokines, growth factors (CCGFs), lipid metabolism, and hematological parameters in non-cardiac populations remains underexplored. We investigated associations between plasma cytokines and lipid-related biomarkers and their relationships with circulating blood cell counts in a cohort of 164 essentially healthy adults aged 18-44 years.

The incidence of human papillomavirus positive oropharyngeal squamous cell carcinoma (HPV+ OPSCC) has increased the past decades. Initial reports disclosed that HPV type 16 (HPV16) was predominant and that patients with HPV+ OPSCC were generally younger and had a better prognosis than those with HPV negative (HPV-) OPSCC. However, recent reports suggest that age differences between patients with HPV+ and HPV-OPSCC are less pronounced and that other high-risk HPV types (HR-HPV) are becoming more common.

Water under hydrophobic confinement: entropy and diffusion.

J Chem Phys

August 2025

Ångström Laboratory, Department of Chemistry, Uppsala University, 751 21 Uppsala, Sweden.

The properties of liquid water are known to change drastically in confined geometries. A most interesting and intriguing phenomenon is that the diffusion of water is found to be strongly enhanced by the proximity of a hydrophobic confining wall relative to the bulk diffusion. We report a molecular dynamics simulation using a classical water model investigating the water diffusion near a non-interacting smooth confining wall, which is assumed to imitate a hydrophobic surface, revealing a pronounced diffusion enhancement within several water layers adjacent to the wall.

Innate behaviours allow solitary animals to complete essential tasks in the absence of social learning. However, we know little about the degree to which ecologically relevant innate preferences can change, and a complete extinction of innate preferences has rarely been shown. The hoverfly Eristalis tenax, a solitary generalist pollinator, is an ideal model for studying innate behaviour in a naturalistic context because its survival depends on the innate ability to identify flowers across many habitats, which could necessitate both learning and unlearning floral objects.
