Novel near-infrared (NIR) luminescent copolymerized hybrid materials were prepared by covalently grafting and physically doping Ln complexes (Ln = Er, Sm, Yb, and Nd) into a copolymer matrix built from nanobuilding blocks. The structures of the obtained hybrid materials were investigated by Fourier transform infrared (FTIR) spectra, nuclear magnetic resonance (NMR), gel permeation chromatograph...

Carbon nanofibers (CNFs) have been incorporated into poly(methyl methacrylate) (PMMA) through electrospinning. The resulting micro- and nanofibers have been characterized by Scanning Electron Microscopy (SEM), which confirmed fiber formation and demonstrated a core-sheath structure of the PMMA fibers. Thermogravimetric Analysis (TGA) was used to obtain the thermal properties of the materials, i...

Thermal behaviors of eucalyptus wood residue (EWR) filled recycled high density polyethylene (HDPE) composites have been measured applying the thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC). Morphology of the materials was also studied using scanning electron microscope (SEM). Addition of the EWR into the recycled HDPE matrix reduced the starting of degradation tem...

TiO2 nanotube arrays are well-known efficient UV-driven photocatalysts. The incorporation of graphene quantum dots could extend the photo-response of the nanotubes to the visible-light range. Graphene quantum dot-sensitized TiO2 nanotube arrays were synthesized by covalently coupling these two materials. The product was characterized by Fourier-transform infrared spectrometry (FTIR), scanning e...

Abstrcat High density polyethylene (HDPE) composite reinforced with 20wt% orange peels ash particles (OPAp) was prepared by compression moulding. Thermogravimetric analysis (DTA/TGA) (space) was conducted on the HDPE/orange peels ash particle composite to clarify the effect of OPAp on the thermal decomposition behavior of the resultant composite. The values of the activation energy for thermal ...

The pyrolytic kinetics of Phragmites australis was investigated using thermogravimetric analysis (TGA) method with linear temperature programming process under an inert atmosphere. Kinetic expressions for the degradation rate in devolatilization and combustion steps have been obtained for P. australis with Dollimore method. The values of apparent activation energy, the most probable mechanism f...

in the present investigation, a novel adsorbent, ionic liquid modified magnetic nanoparticles (il-fe3o4), was successfully synthesized and characterized by ft-ir spectroscopy, thermogravimetric analysis (tga), xrd analysis, scanning electron microscopy (sem) and theory of brunauer, emmett, and teller (bet) for removal of reactive orange 122 (ro-122) from aqueous solutions. the effects of variou...

For the anionic polymerization of ?-caprolactam to polyamide-6 residual monomer concentration in final polymer is an important characteristic. To determine this concentration, a fast and fail-safe method was developed, which couples thermogravimetric analysis (TGA) with Fourier transform infrared spectroscopy (FTIR) gas analysis. FTIR allows identification types gasses released during heat trea...

In this research, magnetic animal bone meal nanoparticles functionalized with ethylenediaminetetraacetic acid (Fe3O4@ABM-EDTA) is reported as a green recyclable catalyst that catalyzed synthesis of biscoumarin derivatives in water. The catalyst was characterized by the Fourier transform infrared spectroscopy (FT-IR), thermogravimetric analysis (TGA), differential thermogra...

The main objective of this work was the incorporation of reactive isocyanate groups into chitin and chitosan in order to effectively use the products as reactive thickening agents in castor oil. The resulting gel-like dispersions could be potentially used as biodegradable lubricating greases. Three different NCO-functionalized polymers were obtained: two of them by promoting the reaction of chi...
