Konstrukcije koloseka na čvrstoj podlozi primenjuju se vise od stotinu godina, najpre u metroima i tunelima, a danas kao standardno rešenje u urbanom okruženju i kao jedno od rešenja na prugama za velike brzine. U upotrebi su sledeći sistemi konstrukcija koloseka na čvrstoj podlozi: monolitni sistemi sa pragovima na betonskoj ploči sa diskretnim ...

Fluorene‐functionalized spiro‐phenothiazine (PTZ‐Fl) exhibits strong Li+ affinity and thermal stability, enabling a PCE of 25.75% in small‐area cells and 22.07% in 25 cm2 modules. Under ISOS‐L3 conditions, PTZ‐Flbased devices retain over 80% efficiency after 1000 hours, demonstrating superior stability and scalability compared to spiro‐OMeTAD for next ...

The need and benefit of slab track: case of Lithuania
Slab track structures have been used in the world for several decades now. However, the ballasted track is still much more popular compared to slab track structures, which is primarily due to its lower price. This article reviews and analyses development

Polymorph‐Specific Electronic Transduction in WO3 during Molecular Sensing
Metal‐oxide polymorphs with similar surface chemistry can nevertheless exhibit distinct sensing properties. In γ‐ and ε‐WO3, analyte adsorption appears comparable; yet, only ε‐WO3 induces a pronounced lattice electronic perturbation that accommodates charge in sub‐conduction band minimum states.
