Non-destructive Fourier Transform InfraRed (FTIR) mapping of Eocene aged fossil reptile skin shows that biological control on the distribution of endogenous organic components within fossilized soft tissue can be resolved. Mapped organic functional units within this approximately 50 Myr old specimen from the Green River Formation (USA) include amide and sulphur compounds. These compounds are mo...

7 Abstract 8 A systematic investigation of the thermal decomposition of viscoelastic memory 9 foam (VMF) was performed using thermogravimetric analysis (TGA) to obtain the 10 kinetic parameters, and thermogravimetric analysis coupled to Fourier Transformed 11 Infrared Spectrometry (TGA-FTIR) and thermogravimetric analysis coupled to Mass 12 Spectrometry (TGA-MS) to obtain detailed information o...

The present study deals with the assessment of antimicrobial activity (antibacterial, antifungal and antiyeast) of bio-oil from Pongamia glabra, Mesua ferrea and Parachlorella spp deoiled cake. The bio-oil from the respective deoiled cakes were obtained via the process of pyrolysis (ambient to 500°C at a heating rate of 40°C/min) in a vertical tubular fixed bed reactor in nitrogen atmosphere. B...

An accurate understanding of molecular structure evolution during pyrolysis is essential for the clean utilization coal. In this study, middle-rank coal was taken as research subject, and vitrinite inertinite samples were stripped from using a hand picking sink–float separation process. situ Fourier transform infrared (FTIR) spectroscopy in X-ray diffraction (XRD) performed to compare macromole...

Composite molecular sieves, FAU/SBA-15, having core-shell structure were synthesized. The synthesized composite sieves were characterized by X-ray diffractometry (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), energy dispersive X-ray spectroscopy (EDS), pyrolysis fourier transform infrared (Py-FTIR) spectroscopy, temperature programmed desorption spectra (NH3-...

Bismuth oxide thin films were obtained by the spray pyrolysis method using bismuth acetate as the precursor salt. The films were characterized by X-ray diffraction (XRD), Fourier Transform Infrared (FTIR), UV-vis diffuse reflectance, X-ray Photoelectron Spectroscopy (XPS) and Scanning Electron Microscopy (SEM). The XRD patterns indicated that the pure β phase is obtained at 450 °C and was also ...

Biomass was subjected to conventional and microwave pyrolysis, to determine the influence of each process on the yield and composition of the derived gas, oil and char products. The influence of pyrolysis temperature and heating rate for the conventional pyrolysis and the microwave power was investigated. Two major stages of gas release were observed during biomass pyrolysis, the first being CO...

This study investigates the efficacy of a prepared Ni/θ-Al 2 O 3 catalyst during pyrolytic conversion Parachlorella kessleri HY-6 and compares results with non-catalytic conversion. The was characterized by techniques such as Brunauer–Emmett–Teller (BET) for surface area, acidity, X-ray powder diffraction (XRD). Isoconversional combined kinetic methods were used to kinetics process. at 10, 20, ...
