Synthesis and Characterization of Nano hydroxyapatite Powder Using Wet Chemical Precipitation Reaction
Viscoelasticity of Asphalt Modified With Packaging Waste Expended Polystyrene
Polyethersulfone/poly (butylene succinate) membrane: Effect of preparation conditions on properties and performance
In this study, biodegradable polymer of poly (butylene succinate) (PBS) was blended with
polyethersulfone (PES) to prepare a novel semi-biodegradable membrane. The effect of blend ratio
and coagulation bath ...
Isolation, purification and biochemical characterization laccase enzyme from microorganisms of gut extract of termit
through the industries effluents. In this study, isolated and purification of the laccase enzyme from bacteria in the gastro-intestinal tract termite will be addressed. Then, the bacteria producing laccase were selected and characterization of laccase...
A simple recoverable titration method for quantitative characterization of amine-functionalized carbon nanotubes
A simple recoverable titration method is described for quantitative characterization of amine functions attached to the carbon nanotubes (CNTs). This titration is a two-step method, originated from the alkaline nature of amine functions. The amount...
Preparation and characterization of modified polyphenylsulfone membranes with hydrophilic property for filtration of aqueous media
In the present research, the low water flux of polyphenylsulfone (PPSU) membranes was addressed and a novel improvement in their water permeation and fouling resistance was achieved using polyethylene glycol (PEG) as the ...
Experimental study of the effect of zeolite 4A treated with magnesium hydroxide on the characteristics and gas-permeation properties of polysulfone-based mixed-matrix membranes
Nowadays, new methods for gas-separation processes are being quickly developed. The separation of CH4/CO2 and CH4/H2 is usually the subject of most related research studies, especially in the membrane gas-separation process, ...
Characterizations based on moments of the number of observations near-order statistics
random variables, see for example
Balakrishnan and Stepanov (2005) and Dembinska et al. (2007). We provide some
characterization results of F based on moments of K+(n;k;a) and K(n;k;a) using the
concept of completeness (Higgins, 2004...
