A ComputationalStudy on Type-I Sn Clathrateswith Inorganic and Organic Guests

Abstract Semiconducting clathrates are a class of inclusion compounds where monatomic cations or anions are encapsulated in a framework made mainly of Si, Ge, Sn, and Sb atoms. In this study, we use density functional theory (DFT) computations to investigate a series of type-I cl...

Dicyandiamide-driven surface reconstruction of high-loading highly-dispersed Fe-N-C catalysts for enhanced acidic durability

The development of highly active and durable electrocatalysts with no platinum-group metals remains a critical challenge for the widespread commercialization of Proton-Exchange Membrane Fuel Cells. While Fe-N-C materials offer promising initial performance, their structural insta...

High-temporal-resolution chemical characterization of PM0.1 at a Mediterranean background site

Ultrafine particles can penetrate sensitive human organs and are strongly associated with adverse health effects. This study presents the first high-temporal-resolution chemical characterization of PM 0.1 at a Mediterranean background site under conditions in which photochemistry...

Gut Microbiota Signatures and Ecological Network Alterations Associated with Hemodialysis

Hemodialysis (HD) is the most widely used renal replacement therapy for patients with end-stage renal disease (ESRD) and is frequently accompanied by long-term complications that impair quality of life, including metabolic and inflammatory disturbances. Growing evidence suggests...

Sirolimus-eluting balloon for the treatment of peripheral artery disease: SUCCESS PTA real-world single-arm study

BACKGROUND: Outcomes with sirolimus-coated drug-eluting balloons (DEB) have been positive for the treatment of femoropopliteal arterial lesions but have not been studied in a broader patient population. OBJECTIVES: Collect real-world safety and effectiveness data on the SELUTION...

Baseline Investigation of Non-Wild-Type Bacterial Indicators and Antibiotic Resistance Genes in Urban Wastewater from Patras, Greece

Antimicrobial resistance (AMR) is a major public health concern, and wastewater monitoring can complement clinical surveillance by capturing resistance signals at the population level. This exploratory study assessed selected antibiotic-resistant bacteria and antimicrobial resist...

The Optimal Design of a Renewable Energy Production System Including Green Hydrogen Production to Support a Public Building

This study presents a mathematical programming approach for the optimal design of a renewable energy system in a grid-connected public building, incorporating green hydrogen production for surplus energy storage. The system includes wind turbines, solar panels, batteries, a hydro...
