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 ... -
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 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 ... -
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 ... -
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 ... -
Influence of SiC addition on tribological properties of SiAlON
(Elsevier, 2011)The tribological properties of gas pressure sintered SiAlON and its composite with 18 wt% silicon carbide (SiC) against two different mating materials, i.e., alumina and SiAlON are evaluated. SiAlON and SiAlON–18%SiC ... -
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 ... -
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. ... -
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 ... -
Effect of blended cements with natural zeolite and industrial by-products on rebar corrosion and high temperature resistance of concrete
(Elsevier, 2012)In this study, influence of blended cements produced with different types of pozzolans on rebar corrosion and high temperature resistance of concrete was investigated. For this reason, natural zeolite (Z), fly ash (FA), ... -
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 ... -
Torsion of Nonlocal Bars with Equilateral Triangle Cross Sections
(American Scientific Publishers, 2013)The theory based on size dependent non-local elasticity theory can serve as a more reasonable and proper approach in mechanical modeling of micro and nano sized components of nano mechanical devices. In this work, a nonlocal ... -
Closed-Form Solutions for Gradient Elastic Beams with Geometric Discontinuities by Laplace Transform
(Hindawi, 2013)The static bending solution of a gradient elastic beam with external discontinuities is presented by Laplace transform. Its utility lies in the ability to switch differential equations to algebraic forms that are more ... -
Covalent grafting of pyridine-2-methanol into kaolinite layers
