medium density fiberboard (mdf) was produced using moist depithed bagasse stored dry or wet. the duration of storage for either method varied between 0 to 4 months. two steaming temperatures of 175c and 185c were also used. mdf boards were produced in the laboratory and the common mechanical and physical properties were measured and compared. results showed that an increased steaming temperat...

Front cover: The four images (in clockwise order) illustrate biofilm development on paper machine surfaces. FESEM image of Deinococcus geothermalis cells attached to a stainless steel surface ⇒ FESEM image of interconnected cells of D. geothermalis within a cell cluster ⇒ Stereomicroscope image of biofilm microcolonies ⇒ Photograph of mature biofilms adhering to stainless steel surfaces in the ...

zno nanocrystalline thin films were synthesized using cathodic reduction of zn foil in aqueous electrolyte containing  zncl2 and h2o2, followed by annealing at 400 oc in the air. the x-ray diffraction pattern exhibited a set of well-defined diffraction peaks corresponding to the zno wurtzite phase. scanning electron microscope and transmission electron microscope images clearly revealed formati...

physicochemical and mechanical properties of wheat grains can have a great impact on the quality of the final products (bread). therefore, correct selection of wheat cultivar for specific applications seems to be crucial. in this study, the differences in the physicochemical and mechanical properties (under compression and impact loadings) of ten iranian wheat cultivars (azar2, alamut, bam, bah...

Effect of zirconia nanoparticles (zirconia NPs/ZrO2 NPs) modified by 3 wt.% (glycidyloxypropyl) triethoxysilane – GPTES (m-ZrO2 on some properties epoxy coating such as mechanical properties, thermal stability and anti-corrosion performance was investigated. The obtained results indicated that the addition to could enhance this coating. 2 pure ZrO2 NPs (u-ZrO2 matrix increase (hardness adhesion...

Zinc oxide (ZnO) thin films were prepared by modified Successive Ionic Layer Adsorption and Reaction (SILAR) method. The optical, structural and antibacterial properties of the prepared ZnO films were analyzed as a function of its annealing temperature lying in the range of 250oC to 450oC. Optical properties were studied using UV-Visible spectroscopy and Photoluminescence spectroscopy (PLS). Op...

Backscattered electron (BSE) imaging is most commonly performed by applying accelerating voltages of 10kV and above to the specimen. For imaging of surface detail, the application of a lower accelerating voltage results in less beam penetration, spread and overall specimen damage. A field emission scanning electron microscope (FESEM) operated with high emission current (50μA) was used to increa...

In this paper, 2wt.% Fe doped TiO2 nanopowder was prepared by a combination of sol-gel and mechanical alloying methods. The mechanical alloying of Fe powder with Ti(OH)4 gel produced from the sol-gel method was used to produce Fe doped TiO2 nanopowder. The synthesized samples were characterized by X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM) and diffuse reflectan...
