The synthesis of polynorbornene by ring opening metathesis polymerization (ROMP) in the presence of 1 2 generation Grubbs catalyst-functionalized nanotubes, is reported. A characterization of the 2 generation Grubbs catalystfunctionalized nanotubes was performed by TGA (Thermogravimetric Analysis) on-line connected with a quadrupole-mass spectrometer, in order to quantify the amount of catalyst...
Nano-sized ZnO particles of specific morphology were synthesized using the plant leaf extracts of Aloe vera. The structures, morphology, optical properties, surface area and thermal behavior of these fabricated ZnO nanoparticles were characterized by X-ray Diffraction (XRD), Scanning Electron Microscopy (SEM), Ultravioletvisible spectroscopy (UV-vis), Photoluminescence (PL)/flourescence spectro...
Epoxy has been widely used as a coating material to protect the steel reinforcement in concrete structures, because of its outstanding processability, excellent chemical resistance, good electrical insulating properties, and strong adhesion/affinity. The major disadvantage raised from exothermic curing reaction highly crosslinked epoxy matrix is brittleness microcracks that change performances....
The p-anisidine is widely used as chemical intermediate in the production of various dyes, pigments, and pharmaceuticals. This study was aimed to evaluate the effect of biofield energy treatment on the physicochemical and spectroscopic properties of p-anisidine. The study was performed after dividing the sample in two groups; one was remained as untreated and another was subjected to Mr. Trived...
In this study, n-dodecanol and 1-tetradecanol were nanoencapsulated by poly(methyl metharcylate-co-methacrylic acid) (p(MM-co-MA)) wall using emulsion polymerization method which was defined as one-stage (OS) or two-stage (TS). Nanocapsules analyzed Fourier-transform infrared (FT-IR) spectroscopy, transmission electron microscopy (TEM), differential scanning calorimeter (DSC) thermogravimetric ...
With the aim to enhance interfacial adhesion of a hydrophobic polymer matrix and cellulosic fibers and fillers, chemical surface modifications with silane coupling agents are performed. Thermogravimetric analysis (TGA) could be used to determine the degree of surface functionalization. However, similar thermal properties of treated and untreated cellulose hamper a precise determination of silan...
The methylsulfonylmethane (MSM) is an organosulfur compound having sulfonyl functional group. It is occurred naturally in some primitive plants and used in disease related to chronic pain, inflammation, and arthritis. This study was attempted to evaluate the impact of biofield energy treatment on the physical, thermal, and spectral properties of MSM. The study was performed in two groups viz. t...
Currently, the mechanical performances of polylactic acid (PLA) samples prepared using fused filament fabrication (FFF) technique are relatively poor. Hence, carbon fiber (CF) is used to improve thermal stability and property FFF-ed PLA in this paper. The crystalline structure, stability, melt flow rate, tensile strength fractured surface morphology PLA/CF were investigated with an X-ray diffra...
There is worldwide interest in deriving increasing amounts of energy from bio-based agricultural materials including not only lignocellulosic residues but also a significant quantity of available livestock manure. This manure can be used as a feedstock for various thermochemical conversion processes such as pyrolysis and gasification. In order to apply these processes, the manure must be proper...
