Abstract:

The formation of metastable alumina phases due to the oxidation of commercial FeCrAl alloy wires (0.5 mm thickness) at various temperatures and time periods has been examined. Samples were isothermally oxidised in air using a thermogravimetric analyzer (TGA). The morphology of the oxidised samples was analyzed using an Electronic Scanning Electron Microscope (ESEM) and X-ray on the surface analysis was done using an Energy Dispersive X-Ray (EDX) analyzer. The technique of X-Ray Diffraction (XRD) was used to characterize the phase of the oxide growth. The entire study showed that it was possibl

Abstract:

An inexpensive and simple multi-sample holder assembly was designed and constructed for the Quantasorb® surface area analyzer which is based on the BET gas adsorption isotherm principle. Four sample holder U-tubes were connected in parallel in order to maintain all samples equidistant from the detector. This arrangement keeps high gas detection sensitivity and minimizes the occurrence of unwanted turbulent gas flows in the system. The system was tested by measuring surface areas of reference standard samples. Excellent agreement was obtained. Key words: BET method, gas adsorption, gas flow syt

The evolution of the kinetic energy distribution of photoelectrons from a cube-oriented aluminum sample during tensile deformation was probed with a retarding field energy analyzer. Because of the anisotropy of the aluminum work function, the electron-energy distribution is altered as the area fractions of the major surface planes change during deformation. In cube-textured aluminum, deformation reduces the {100} area fraction and the relatively low energy electrons from these surfaces. Conversely, the {110} and {111} area fractions and the relatively high energy electrons from these surfaces

Abstract:

The present work reported the adsorption of Cr (VI) from aqueous solutions on activated carbon prepared from mango kernel, a seasonal wastefrom mango fruits. Kernels from dried mango fruit shells were taken out and pulverized in a micro-pulverizing mill. The powder thus obtained wasactivated with 40% H3PO4 and carbonized at 600 °C for 1 hour in an inert atmosphere. Physico-chemical characteristics such as elementalcomposition, surface area, functional groups and surface morphology of the activated carbon were analyzed using elemental analyzer, BET surfacearea analyzer, FTIR spectroscopy and SE

Abstract:

Layer by layer metal-organic framework (MOF) supported on zirconium phosphate (ZrP) was synthesized at very mild conditions and used for the liquid phase oxidation of cyclohexene in solvent free condition in the presence of molecular oxygen. The MOF-ZrP was characterized by X-ray diffractometer (XRD), scanning electron microscope (SEM), thermal gravimetric analyzer (TGA), Fourier-transform infrared spectrometer (FT-IR) and Brunauer-Emmett-Teller (BET) surface area analyzer. The characterization shows a smooth morphology of MOF-ZrP with good stability under 200 °C having surface area 285 m2/g.

Abstract:

The internal structure of diatomite has nanometer-level micropore and fine adsorptivity, but internal porosities of crude diatomite were blocked by impurities which should be removed. The characteristics of original and scrubbed diatomite were compared by SEM,TEM,specific surface area analyzer and FT-IR. The test results indicated that the SiO2content of scrubbed diatomite increased from 80.61% to 89.56%, specific surface area increased from 7.96 m2/g to 14.39 m2/g and the external activity improved, and the adsorption of performance of scrubbed diatomite was better than that of original diato
