Children’s perceptions of natural history museums: Insights from the “Young Naturalists” program in Portugal

Children and adolescents are a key audience for scientific and cultural outreach and literacy. As future citizens, voters, and taxpayers, their education—carried out in formal, informal, and non-formal contexts—is crucial for societal development. In this context, scientific cult...

Tracing source and paleoweathering conditions of the lower jurassic sandstone from sierra de santa rosa section, Northern Sonora, México

The Lower Jurassic sedimentary rocks of the Sierra de Santa Rosa Formation in northern Sonora, Mexico has been deposited in a forearc basin and its age has been assigned based on the fossil assemblages and detrital zircon U–Pb geochronology data. Neverthless, their geochemical ch...

Inhalable Dry Powders of Antimicrobial Agents in Respiratory Diseases

Background Respiratory infections remain a major global health burden despite advances in systemic antimicrobial therapy. Antimicrobial dry powder inhalers (DPIs) have emerged as precision-engineered pulmonary delivery platforms capable of achieving high local drug concentrations...

Thermally Driven Reorganization of Polytypic PbI2 Precursor Films Improves MAPbI3 Formation and Crystallization

Abstract Despite rapid progress in solution-processed MAPbI3, the role of PbI2 polytypism in two-step conversion remains largely unexplored. Here, we show that thermally driven reorganization of polytypic chemical-bath-deposited PbI2 thin films influences the subsequent formation...

Determining the Chain Conformation, Microstructure, and Antioxidant Activity of Fucoidan from Dictyota dichotoma Growing in the Sea of Cortez, Mexico

Brown algae, such as Dictyota dichotoma, contain fucoidan, whose bioactivity is linked to its molecular characteristics, which are in turn defined by environmental conditions. D. dichotoma fucoidan from the Sea of Cortez in Mexico (DDFSC) has not been previously investigated. Thi...

Antimicrobial activity of coffee bagasse (Coffea arabica) extract against phytopathogenic bacteria and fungi

Abstract Plant diseases caused by microbial pathogens represent a major challenge for global agriculture, leading to annual crop losses estimated at more than USD 220 billion. The search for sustainable antimicrobial agents derived from agro-industrial by-products has gained incr...

Coaxial Electrospun PCL/PLA-CA Polymeric Membranes for pH-Responsive Acyclovir Delivery in Antiviral Scaffolds

Herpes simplex virus types 1 and 2 (HSV-1 and HSV-2) cause recurrent skin infections that are difficult to treat because of the limited solubility and permeability of acyclovir (ACV). This study developed electrospun polymeric membranes based on polycaprolactone (PCL), poly(lacti...
