Cation-aromatic nitrogen interaction as a design principle for sodium deep eutectic electrolytes

We report a combined experimental and ab initio molecular dynamics investigation into the role of nitrogen hybridization (sp2 vs sp3) and ring aromaticity in the sodium-based deep eutectic electrolyte formation and their potential use in sodium-ion battery electrolytes. Mixtures...

Magnetothermally Responsive Mesoporous Silica Nanocarriers: Materials Design, Thermoresponsive Gates and Controlled Drug Release

Magnetothermally responsive nanocarriers represent a promising platform for spatio-temporally controlled drug delivery by combining alternating magnetic field (AMF)-induced heating with thermally triggered cargo release. Among the available architectures, magnetite-core/mesoporou...

Happiness at work and sales performance: evidence from sales representatives

Purpose This study aims to examine the relationship between multidimensional happiness at work and sales representatives’ performance in an insurance brokerage. It analyses the associations between engagement, job satisfaction and affective commitment, while testing the mediating...

Streamlining Habitats Directive Reporting with Open Biodiversity Data: Evidence for the Nature Directives Stress Test [Policy Brief]

Biodiversity monitoring under Article 17 of the EU Habitats Directive (Council Directive 92/43/EEC) remains inconsistent across European Member States. Although all Member States follow the same reporting framework, national assessments are based on national monitoring programmes...

Reconfiguring University Missions in the Knowledge Society: The Case of Portuguese Universities in European Alliances

ABSTRACT This paper examines how European Knowledge Society policy scripts, amplified by the European Universities initiative, are appropriated in the strategic plans of Portuguese public universities. Focusing on nine universities participating in European Universities Alliances...

Bioaccumulation and exposure to potentially toxic elements (PTEs) in marine species commercialized for human consumption in the Southern Region of Rio de Janeiro (SE, Brazil)

Sepetiba Bay (Rio de Janeiro, Brazil) is a semi-enclosed coastal system subject to significant anthropogenic pressures resulting from historical industrial activities, port operations, and urban runoff. This study aimed to evaluate the occurrence, organ-specific accumulation, and...

Nanoparticle Emissions of Ageing Diesel Cars with DPF—A First European PTI-like Field Study

This paper investigates nanoparticle emissions from older diesel passenger cars in four European countries outside of PTI (periodic technical inspection) testing facilities, using a methodology similar to that of the PTI. Per opportunistic sampling and voluntary testing, 618 dies...

Long-Lived Interfacial Charge Separation in PyrenylimidazolylPhthalocyanine@Transition Metal Dichalchogenide Heterostructures

Abstract Pyrenylimidazolyl-functionalized free-base phthalocyanines (H2Pc) and their zinc complexes (ZnPc) constitute multifunctional building blocks for realizing heterostructures with liquid phase exfoliated transition-metal dichalcogenides (LPE-TMDs). Here, we report the synth...

ESG performance and business risk in Iberian companies: exploring gender diversity moderating effect

Purpose This study aims to examine the impact of Environmental, Social and Governance (ESG) performance on business risk and investigates how board gender diversity moderates this relationship. Design/methodology/approach Using panel data from 367 listed firms in Portugal and Spa...

Waste Literacy Among Portuguese First-Year Tertiary Students After Compulsory Environmental Education

Waste management is essential for addressing local and global environmental challenges. Failure to manage waste effectively results in several consequences, including environmental degradation, public health risks, and economic costs. Besides the need for adequate and up-to-date...

Highly Stretchable Eu 3+ ‐ Doped PEBAX Elastomers With Complementary Optical Readouts of Strain and Temperature

ABSTRACT Soft photonic materials capable of maintaining optical functionality under large mechanical deformation are highly desirable for wearable photonics, flexible sensors, optical and mechanically adaptive photonic systems. Here, we report highly stretchable luminescent elast...

Thermophysical behavior of clinically relevant peloid formulations: a study using residual smectitic soils and mineralized waters

Abstract Thermotherapy is widely used in thermal centers and can be beneficial for certain pathologies. Peloids are mixtures of fine-grained clay materials and waters of different mineralization and are commonly applied in thermotherapy, where key performance parameters include s...

An Empirical Express Method for Clay Slope Stability Assessment Based on Slip Surface Geometry and Factor of Safety Prediction

Clay slopes are particularly sensitive to variations in soil strength, groundwater conditions, and slope geometry, making their rapid and reliable assessment essential for geotechnical design, landslide prevention, and infrastructure risk management. This study develops and evalu...

How ageism shapes gerontogeriatric competencies in newly graduated nurses: A cross-sectional analysis

This cross-sectional study examined the association between ageism and self-perceived gerontogeriatric competence among newly graduated registered nurses (NGRNs). A total of 242 NGRNs completed an online questionnaire that included the Ambivalent Ageism Scale (AAS) and the Geront...

Primary prevention of child sexual abuse with preschool children in Portugal: A pilot feasibility trial of the CARE program

Background Child sexual abuse (CSA) is a major public health concern, yet rigorously evaluated and fully manualized primary prevention programs for preschool children remain scarce. Evidence on the feasibility and acceptability of such interventions among young children and their...

Intranasal Administration of Isoeugenol Improves Memory Deficits in APP / PS1 Old Mice—A Role Beyond Nrf2 Activation?

Alzheimer's disease (AD), a neurodegenerative disorder and the most common cause of dementia, has no cure or effective treatment; thus, identification of disease-modifying therapeutics is crucial. Nrf2 is a master controller of homeostatic functions whose activity is compromised...
