Investigations of cell immobilization in alginate: rheological and electrostatic extrusion studies
(Wiley, Hoboken, 2006)
In this study, the process of electrostatic extrusion as a method for cell immobilization was investigated. We have assessed the effects of concentrations of yeast cells (as a model cell type) and Na alginate on the size ...
SmartMetals: a new method for metal identification based on fuzzy logic
(John Wiley & Sons Ltd, Chichester, 2009)
This paper presents a method of searching, identifying and cross-referencing metal alloys based on their chemical composition and/or mechanical properties, typically obtained by analysis and tests. The method uses a general ...
Prediction of single particle settling velocities through liquid fluidized beds
(Powder Technology, 2009)
Single particle settling velocities through water fluidized beds of mono-sized glass spheres (dp = 0.645, 1.20, 1.94, 2.98 and 5 mm in diameter) were studied experimentally using a column, 40 mm in diameter. The settling ...
The effect of the mass ratio of hard and soft segments on some properties of thermoplastic poly(ester-siloxane)s
(John Wiley and Sons Ltd, 2004)
A series of thermoplastic elastomers based on soft polydimethylsiloxane (PDMS) and hard poly(butylene terephthalate) (PBT) segments was synthesized using a two-step transesterification reaction in the melt. The molar mass ...
Leaching of copper(I) sulphide by sulphuric acid solution with addition of sodium nitrate
(Elsevier, Amsterdam, 2003)
Finely grained samples of copper(I) sulphide were leached by H2SO4 solution with added NaNO3. The occurrence probability of chemical reactions was analysed based on literature data and products which were formed during the ...
Influence of the common varistor dopants (CoO, Cr2O3 and Nb2O5) on the structural properties of SnO2 ceramics
(Elsevier Science Inc, New York, 2004)
The influence of dopants commonly used in SnO2 varistor ceramics, such as CoO, Cr2O3 or Nb2O5, on the structural properties of SnO2 was investigated. Several SnO2-based ceramics containing only one of the dopants were ...
Microstructural dependence of fracture toughness in high-strength 7000 forging alloys
(Pergamon-Elsevier Science Ltd, Oxford, 2008)
The effects of microstructural parameters associated with the coarse intermetallic phases particles and precipitates on the fracture toughness of the overaged 7000 alloy forgings are investigated. Detailed microstructural ...
Synthesis and single-crystal structure analysis of a new layered zinc phosphate
(Pure and Applied Chemistry, 2005)
A new 2D zinc phosphate [H3NCH(CH3)CH 2NH3]2+0.75[COOH(CH 2)COOH]0.25 (Zn3P3O 11OH)2-* 0.5NH4+ consists of zinc phosphate layers, which are intercalated by diprotonated 1,2-diaminopropane, malonic acid, and NH4+ ions. The ...
Polarization curves in the ohmic controlled electrodeposition of metals
(Oxford : Pergamon-Elsevier Science Ltd, 2009)
The conditions under which ohmic controlled metal electrodeposition occurs are discussed using a simple mathematical model. it is shown that ohmic controlled electrodeposition can be operative if the value of the exchange ...
Modelling of ductile fracture initiation in strength mismatched welded joint
(Pergamon-Elsevier Science Ltd, Oxford, 2008)
In this paper, the effect of strength mismatch and width of the welded joints oil the stress-strain distribution in the crack tip region has been discussed. The single-edge notched bend (SENB) specimens (precrack length ...
