A series of boron doped magnetic zirconium catalysts were developed for the selective transfer hydrogenation of biomass-derived furfural (FFR) into furfuryl alcohol (FA) using 2-propanol as hydrogen source and solvent. Full characterizations with XRD, SEM, TG, Py-IR, NH3-TPD, and CO2-TPD techniques were undertaken to uncover structural properties o...

In this research, we report the structure, microstructure and conduction mechanism study of nickel and cobalt co-substituted Mn3O4 with systematic variation in cobalt concentration. Co-substituted Mn3O4 was prepared by coprecipitation technique in an aqueous solution of metal nitrates and ammonia. X-ray diffraction study of nickel and cobalt co-sub...

This paper focusses on investigating and comparing the congruent crystallization of phosphate glasses with different degrees of polymerization. The study was performed both on powders, with different size fractions, and coarse particles which can be assimilated to bulk. From DSC experiments, corroborated by SEM analysis, it was demonstrated that Li...

AA6060 aluminum alloy was subjected to severe plastic deformation (SPD) through Equal Channel Angular Pressing (ECAP) up to 8 passes via route BC. ECAPed samples isochronally annealed for 1 hour at a temperature range of 150-450°C. The microstructure and texture of the studied material were evaluated by Electron Back scatter Diffraction (EBSD), and...

A series of new imine-linked polymers reveal variations of aliphatic and aromatic linkers were synthesized via Schiff base co-condensation polymerization and fully characterized. The polymers are classified as 1,4- and 1,6-based polymers according to their preparation methodology, which depicted by the polymerization of thiophene-based aryl aldehyd...

Considering the long-term structural stability of polymer-nanotube composites under different service conditions, we investigate the tensile creep of polymer-nanotube composites consisting of poly(methyl methacrylate) (PMMA) and multiwalled carbon nanotubes (MWCNTs). The PMMA is pre-irradiated by ultraviolet light with different doses to change the...

The demand for gluten-free products has been growing over the last few years as is the need to improve their quality. The objective of this research was to develop a shelf life prediction model of gluten-free rusks. To this aim, a kinetic study of the primary and secondary oxidative process was run and the kinetic parameters (rate constant, activat...

This investigation presents novel applications for bioconvection flow of non-Newtonian fluid with diverse flow features. The developed unsteady bio-nano-transport model is formulated under the influence of some novel features such as variable thermal conductivity, heat absorption/generation and activation energy. In contrast to typical investigatio...
