Influence of temperature and alumina catalyst on pyrolysis of corncob
(Elsevier, 2009)Corncob has been investigated as an alternative feedstock to obtain fuels and chemicals via pyrolysis infixed-bed reactor. The influence of pyrolysis temperature in the range 300–800°C as well as the catalysteffects on the ... -
Enrichment and Determination of Ni2+ions in Water Samples with Adiamino-4-(4-nitro-phenylazo)-1H-pyrazole (PDANP) by Using FAAS
(Elsevier, 2010)Nickel, as a heavy metal, is toxic for many living species. Thus, the determination of trace amounts of nickelin environmental samples is of great importance. In the present study, new, sensitive, simple and validatedsolid ... -
Adsorption of Reactive Red 120 from aqueous solutions by cetylpyridinium-bentonite
(Wiley, 2010)BACKGROUND: The removal of Reactive Red 120 (RR 120) from aqueous solutions using cetylpyridinium modified Resadiye bentonite (CP-bentonite) prepared by ion exchange was investigated with particular reference to the effects ... -
Synthesis and characterization of Ba/MCM-41
(TÜBİTAK, 2010)Mesoporous Ba/MCM-41 type materials (Ba/MCM-41) with high Ba/Si molar ratios between 0.025 and 0.1 were synthesized by direct hydrothermal synthesis. The samples were characterized by XRD, nitrogen adsorption, TGA-DTA, ... -
Adsorption Performance and Mechanism in Binding of Azo Dye by Raw Bentonite
(Wiley, 2010)The adsorption behavior of methyl orange (MO) from aqueous solution onto rawbentonite (RB) sample was investigated as a function of parameters such as pH, inor-ganic anion, contact time, and temperature. The Langmuir and ... -
Influence of Beta-Si3N4 Particle Size and Heat Treatment on Microstructural Evolution of Alpha:Beta-SiAlON Ceramics
(Elsevier, 2011)In the present study, we report the effects of starting beta-Si3N4 particle sizes and post-sintering heat treatment on microstructure evolution and mechanical properties of prepared alpha-beta SiAlON ceramics. Three different ... -
Synchronous-Reference-Frame-Based Control Method for UPQC Under Unbalanced and Distorted Load Conditions
(IEEE, 2011)This paper presents a new synchronous-referenceframe (SRF)-based control method to compensate power-quality (PQ) problems through a three-phase four-wire unified PQ conditioner (UPQC) under unbalanced and distorted load ... -
Effects of titanium addition on mechanical and corrosion behaviours of AZ91 magnesium alloy
(Elsevier, 2011)The mechanical properties and corrosion behaviour of AZ91 magnesium alloy containing 0.2–0.5wt.%Ti were investigated in this study. Results demonstrate that the enhancement of the ultimate tensilestrength by 18% and yield ... -
On compact operators and some EulerB(m)-difference sequence spaces
(Elsevier, 2011)Altay and Basar (2005) [1] and Altay, Basar and Mursaleen (2006) [2] introduced the Euler sequence spaces e(0)(t), e(c)(t) and e(infinity)(t). Basarir and Kayikci (2009) [3] defined the B-(m)-difference matrix and studied ... -
Effect of sintering conditions and heat treatment on the properties, microstructure and machining performance of α-β-SiAlON ceramics
(Elsevier, 2012)The properties of SiAlON ceramics are strongly affected by the composition and structure of the intergranular phase, which are controlled by dopants, sintering conditions and starting silicon nitride (Si3N4) powder ... -
On compact operators on the Riesz B-m-difference sequence space
(Springer, 2012)In this paper, we give the characterization of some classes of compact operators given by matrices on the normed sequence space rpq(Bm), which is a special case of the paranormed Riesz Bm-difference sequence space rq, (p, ... -
Utilization of marble dust, fly ash and waste sand (Silt-Quartz) in road subbase filling materials
(Korean Society of Civil Engineer-KSCE, 2012)Large volumes of earthen materials are used in construction each year in Turkey and elsewhere. The wastes generated from these materials can be utilised in various applications including road subbase filling materials. In ... -
A Comparative Study of SiAlON Ceramics
(Elsevier, 2012)Two different varieties of Si3N4 powders were used to prepare SiAlON ceramics. 100% b-Si3N4 was used from refractory grade powders (B1) and another purer 98% a-Si3N4 (50A) powder was used to prepare the SiAlON samples. ... -
Characterization of Unye Bentonite After Treatment with Sulfuric Acid
(Sociedade Brasileira de Química, 2013)Unye bentonite was found to consist predominantly of a dioctahedral smectite along with quartz, tridymite, cristobalite, and minor fractions of feldspar and anatase. A considerable amount of Al was retained as a constituent ... -
Closed-Form Solutions for Gradient Elastic Beams with Geometric Discontinuities by Laplace Transform
