Optimizing mechanical quality factor of cymbal transducer
(Taylor & Francis LTD, 2006)
In general, high mechanical quality factor 'Q(m),' which is the indication of low loss, is a desired property for transducers. However, low Q(m) and wide bandwidth are desired properties for underwater transducer. Therefore, ...
Processing and characterisation of three-layer alumina-based composites with enhanced damage tolerance
(Elsevier Sci LTD, 2005)
Three-layer alumina-based composites reinforced with iron in the inner layer and with chromium in the outer layers were fabricated by first uniaxially pressing the three-layer assembly, followed by cold isostatic pressing ...
Catalytic pyrolysis of biomass: Effects of pyrolysis temperature, sweeping gas flow rate and MgO catalyst
(Pergamon-Elsevier Science LTD, 2010)
Cotton seed, as a biomass source, is pyrolysed in a tubular fixed-bed reactor under various sweeping gas (N(2)) flow rates at different pyrolysis temperatures. In the non-catalytic work, the maximum bio-oil yield was ...
Bio-oil production from rapid pyrolysis of cottonseed cake: product yields and compositions
(Wiley, 2006)
Fixed-bed fast pyrolysis experiments have been conducted on a sample of cottonseed cake to determine the effects of pyrolysis temperature, heating rate and sweep gas flow rate on pyrolysis yields and chemical compositions ...
Fast pyrolysis of sesame stalk: yields and structural analysis of bio-oil
(Elsevier Science BV, 2004)
Sesame stalk pyrolysis experiments were conducted in a fixed-bed reactor in an attempt to determine the effects of pyrolysis temperature, particle size, heating rate and sweeping gas (N-2) flow rate on the product yields ...
Mineralogical and technological properties of underclays in Sile Region, Istanbul, Turkey
(2007)
Sile Region, northeastern Istanbul, includes the most important underclay deposit of Turkey. In the area, Upper Cretaceous calc-alkaline volcanic rocks are the major parent rocks of the Neogene sequence composed of plastic ...
Proprietà Mineralogiche e technologiche di argille sotto strato di carbone provenienti dall'area di Sile (Istanbul, Turchia)
(2007)
Sile Region, northeastern Istanbul, includes the most important underday deposit of Turkey. These days are composed of disordered kaolinite, illite, mixed-layer illite-smectite, smectite, gibbsite, quartz, pyrite, anatase, ...
Effect of activators and calcination on luminescence properties of åkermanite type phosphors
(Scientific Publishers, 2015)
Ákermanite type Ca2MgSi2O7 phosphors activated with different types of rare earths have been synthesized through a solid state reaction method under weak reducing atmosphere and/or open atmosphere. The phase properties of ...
Effect of kaolin type on pyroplastic deformation of sanitaryware porcelain body [Kaolen türünün saglik gereçleri porselen bünyesinin piroplastik deformasyonu üzerine etkisi]
(Gazi Universitesi Muhendislik-Mimarlik, 2016)
Pyroplastic deformation is one of the major problems of sanitaryware production, because of high temperature firing and high amount of glassy phase and this problem can be reduced by controlling of amount of glassy and ...
Sintering of 94Na0.5Bi0.5TiO3-6BaTiO3 with SPS and conventional methods for crystal growth
(Hanyang University, 2016)
In this study, lead-free 94Na0.5Bi0.5TiO3-6BaTiO3 (94NBT-6BT) piezoelectric ceramics and embedded single crystals in polycrystalline 94NBT-6BT matrix were sintered by conventional (CS) and spark plasma sintering (SPS) ...
