Physical and mechanical properties of wood composite from oil palm (Elaeis guineensis Jacq.) fronds
This study involves the production of wood composite from oil palm fronds (OPF). The aim was to determine the wood composite properties fabricated from three different OPF sections, i.e., bottom, middle and top sections bonded with either phenol formaldehyde (PF) or urea formaldehyde (UF). The results showed that rega…

Опыт применения капсулированного ингибитора коррозии Scimol WSC в скважинах Когалымского месторождения
Corrosion control is an important area on the way to minimize costs in the process of oil production. Innovative solution to the «Mirrico» GC in this area is the development of encapsulated corrosion inhibitors. The article contains results of pilot testing of a new product, showed a high protective effect and prolong…
Fabrication of Flexible Follow Fibers of Mesoporous Silica
Hollow nanofibers with mesoporous silica walls have been fabricated using electrospun polymer nanofibers and surfactant micelles as templates. The nanofibers are the possible candidates for insulating materials due to their high porosity. We aimed to remedy the fragility of the nanofibers by introducing the organo-sil…
Study ofAl-Al3Fe in high frequency magnetic induction fusionAlÃÂFe
The materials under consideration are binary aluminium-iron alloys (5at.% to 58at.%) elaborated by high frequency magnetic induction fusion. The resulting microstructures have been observed by standard metallography, x-ray powder diffraction and microhardness measurements. Structure of eutectic Al3Fe phase is describe…
Development of Zeolite Catalyst Which has High Selectivity by Mechanochemical Treatment
A new method for the surface deactivation of zeolite catalyst was tested via a mechanochemical approach using powder composer. Post-synthetic mechanochemical treatment of ZSM-5 zeolite causes a selective deactivation of catalytically active sites only existing on the external surface, giving a unique ZSM-5 zeolite cat…
Synthesis of a rare Earth Free Oxynitride Phosphor for white LED Application
The purpose of this research was to promote the performance of rare earth free oxynitride phosphor (BCNO: boron carbon oxynitride) for next generation of white LED. In particular, I undertook the following research topics, (1) Preparation of spherical BCNO phosphor particle via spray pyrolysis and (2) Enhancement of P…
Synthesis of Perovskite Oxide Nanocubes
Synthesis of barium zirconate (BaZrO3) nanocubes with perovskite structure was carried out by the composite-hydroxide-mediated (CHM) approach. The synthesis was conducted using zirconium dioxide (ZrO2) as a zirconium-source starting material and barium hydroxide［Ba(OH)2］ as a barium-source starting material. Through t…

Influences of the rate and of the direction of plastic deformation on the corrosion behaviour of compressed iron-based alloys
After having been subjected to intense stresses metallic alloys can be partially or totally affected by a permanent geometric change. The resulting much higher dislocations densities may lead to severe microstructure disorder inducing possibly changes in the surface reactivity of the piece, after or not machining. It…

Characterization of mechanochemically synthesized CaO·ZnO.K2CO3
The mixed oxide of CaO·ZnO and K2CO3 were prepared by ball milling of CaO and ZnO powders and water, with addition of K2CO3 and afterward by calcination at 700 oC. Influence of different molar ratio of K2CO3 and CaO (x=1, 2 and 4 moles of K2CO3 per 10 moles of CaO) was studied . The prepared samples were characterized…
