Removal of lead from water by amino modified multi-walled carbon nanotubes
(Elsevier Science Sa, Lausanne, 2011)
Pristine, oxidized, ethylenediamine, diethylenetriamine and triethylenetetramine modified multi-walled carbon nanotubes (raw-MWCNT, o-MWCNT, e-MWCNT, d-MWCNT and t-MWCNT, respectively) were employed as adsorbents in order ...
Electrochemical determination of glucose using polyaniline electrode modified by glucose oxidase
(Elsevier Sci Ltd, Oxford, 2011)
Polyaniline (PANI) enzyme electrode was formed by immobilisation of Glucose oxidase (GOx) via glutaraldehyde into electrochemically polymerised PANI on graphite electrode. Electrochemical polymerisation of PANI on graphite ...
Tube for obtaining crystals in a laboratory furnaces
(Maik Nauka/Interperiodica/Springer, New York, 2011)
A model of an air-cooled tube with a number of movable plugs, installed in a laboratory tube furnace is presented. The setup (modular "crystallization shelf-comb") allows easy regulation and simultaneous crystallization ...
Carnauba wax microparticles produced by melt dispersion technique
(Springer International Publishing Ag, Cham, 2011)
Melt dispersion technique was investigated for carnauba wax microparticles production. Microbeads with spherical shape and narrow size distribution were produced. The main objective of this study was to investigate the ...
The effect of the shape and size of the pores on the mechanical properties of porous HAP-based bioceramics
(Elsevier Sci Ltd, Oxford, 2011)
In this study, the influence of the shape and size of the pores on the mechanical properties of the obtained porous HAP-based bioceramics was investigated. The porous HAP-based bioceramics were obtained starting from ...
Thermoplastic Copolyester Elastomers
(Handbook of Engineering and Speciality Thermoplastics: Polyethers and Polyesters, 2011)
In this chapter the preparation, structure and properties of thermoplastic copolyester elastomers, TPEE, are presented. TPEEs are multiblock copolymers built up from so-called short crystallizable hard segments and long ...
Biodegradable polyesters: Synthesis and physical properties
(RSC Green Chemistry, 2011)
Structural changes of Ca-alginate beads caused by immobilized yeast cell growth
(Elsevier Science Bv, Amsterdam, 2015)
Structural changes of Ca-alginate bead due to yeast cell loading and the impact on their mechanical properties were studied based on experimental data of cell number density per beads, cell rearrangement within the bead ...
Impact of sodium sulfate solution on mechanical properties and structure of fly ash based geopolymers
(Springer, Dordrecht, 2015)
In this paper, geopolymers based on two different fly ash samples were exposed to sodium sulfate (Na2SO4) solution (50 g/l) over a period of 365 days. It was found that sulfate solution attack caused a small decrease in ...
