Abstract. Dry reforming of methane (DRM) is a trendy topic investigation as means reducing global warming. However, the adoption DRM for commercial purpose still question due to deactivation and sintering catalysts. The performance 5Ni/KCC-1 catalyst by using ultrasonic-assisted impregnation method was examined in this study. micro-emulsion were used prepare KCC-1 support respectively. characte...

In this work, natural-based and biodegradable nanofibers were produced by electrospinning for drug delivery wound dressing applications, using gelatin (Gel), chitosan (CS), cellulose nanocrystals (CNC) natural propolis extract. The polymeric formulations parameters optimized, resulting in the development of Gel/CS with mean diameters 97 nm. CNC successfully introduced into optimized solution vi...

Identification and characterization play an essential role in the study of non-metallic inclusions (NMIs) monitoring steel casting process product quality. This uses Raman spectroscopy, a versatile, relatively fast, non-destructive technique for characterizing oxide sulfide-based inclusion phases samples. The relative peak intensities positions were used to qualitatively estimate Al2O3, CA, C12...

Preservation of cultural heritage is of paramount importance worldwide. Microbial colonization of construction materials, such as wood, brick, mortar, and stone in historic buildings can lead to severe deterioration. The aim of the present study was to give modern insight into the phylogenetic diversity and activated metabolic pathways of microbial communities colonized historic objects located...

A sol-gel derived ZnO-p-Si heterojunction structure were fabricated and investigated as a potential methane sensor. Three configurations with different contacts (Pd-Ag contact both on ZnO and Si / Pd-Ag on ZnO side and Au on Si / and Au on both sides of the junction) were fabricated in order to study the impact of the catalytic contact on the methane sensing properties. Structural characterizat...

WO₃-decorated TiO₂ nanotube arrays were successfully synthesized using an in situ anodization method in ethylene glycol electrolyte with dissolved H₂O₂ and ammonium fluoride in amounts ranging from 0 to 0.5 wt %. Anodization was carried out at a voltage of 40 V for a duration of 60 min. By using the less stable tungsten as the cathode material instead of the conventionally used platinum electro...

We have designed a nano-sheet-like porous organic polymer (POP) constructed via schematic hydrothermal process and characterized it using PXRD, N 2 adsorption–desorption studies, UV-vis, XPS microscopic analyses (TEM FESEM).
