Conversion of KCl into KBH4 by mechano-chemical reaction and its catalytic decomposition
(Springer New York LLC, 2017)
Production of KBH4, in the presence of KCl, B2O3 and MgH2 by means of a mechanical reaction and a dehydrogenation kinetic, constitute the main parts of this study. Operating time and reactant ratio are considered as two ...
Efficient removal of acidic dye using low-cost biocomposite beads
(2013)
The objective of this study is to prepare and characterize chitosan/zeolite biocomposite beads and utilize them as adsorbent for removal of anionic dye, Acid Black 194 (AB194). Characterization studies of biocomposite beads ...
Influence of interstitial filling on breakage kinetics of gypsum in ball mill
(Elsevier, 2011)
Gypsum is an industrial material used in many applications such as building and chemical industry, fertilizer manufacture, medicine and dentistry. In these industries, there is need for finely ground gypsum. Energy consumption ...
An investigation on the effects of the ball filling on the breakage parameters of natural amorphous silica
(Elsevier B.V., 2016)
The effects of ball filling on the selection (Si) and breakage functions (Bi,j) for the natural amorphous silica were investigated in this paper. At four levels (20%, 30%, 40% and 50%) of ball filling, the selection functions ...
The effects of ball filling and ball diameter on kinetic breakage parameters of barite powder
(Elsevier, 2012)
The absolute fineness of the ball diameter and the ball charge grading are important factors for the optimal operation of a ball mill. Therefore, the effects on breakage kinetics of the ball diameter and the fractional ...
A new size distribution model by t-family curves for comminution of limestones in an impact crusher
(Elsevier, 2011)
In the evaluation of crushers, t-family curves obtained from single particle test methods are frequently used. It is known that there are many difficulties and problems in these tests. In this study the breakage behaviour ...
Degradation of poly(vinyl chloride) onto KF-Al 2O 3
(2010)
g-Alumina coated with potassium fluoride, KF-Al 2O 3 proved dehydrochlorination of poly(vinyl chloride), in tetrahydrofuran. The molecular changes was observed in the accurance of polyene sequence distribution by using ...
Preparation of a new polymer-dispersed liquid crystal film by using phthalocyanine-functional photocurable copolymer
(John Wiley and Sons Inc., 2015)
A new, asymmetrical zinc phthalocyanine (aZnPc)-functional photocurable copolymer was prepared by the combination of atom transfer radical polymerization and copper (I)-catalyzed azide-alkyne cyclo-addition (CuAAC) click ...
Effect of attachment types and number of implants supporting mandibular overdentures on stress distribution: A computed tomography-based 3D finite element analysis
(Elsevier Ltd, 2015)
The objective of this study was to calculate stresses in bone tissue surrounding uncoupled and splinted implants that are induced by a bite force applied to the mandible and to determine whether the number of mandibular ...
Preparation and characterization of pH responsive poly(methacrylic acid-acrylamide-N-hydroxyethyl acrylamide) hydrogels for drug delivery systems
(John Wiley and Sons Inc., 2016)
In this study, pH responsive polymers composed of methacrylic acid, acrylamide, and N-hydroxyethyl acrylamide were synthesized by free radical polymerization technique. The characterization was done with Fourier transform ...
