Investigation of Ca-alginate hydrogel rheological behaviour in conjunction with immobilized yeast cell growth dynamics
(Taylor & Francis Ltd, Abingdon, 2007)
The rheological model is developed to elucidate the mechanism of Ca-alginate microbead deformation in the course of cell growth within. It is a complex process influenced by relaxation of the expanded polymer network inside ...
Barium titanate screen-printed thick films
(Elsevier Sci Ltd, Oxford, 2002)
Barium titanate (BT) thick films were prepared from mechanically activated powders based on BaCO3 and TiO2. After homogenization and milling in a high-energy vibro mill, the powders were calcined at 700 degreesC for 2 h ...
Synthesis, characterization and antimicrobial activity of Ni(II) and Zn(II) complexes with N ',N '(2)-bis[(1E)-1-(2-pyridyl)ethylidene]propanedihydrazide. Crystal structures of two highly solvated bimetallic complexes of Ni(II)
(Pergamon-Elsevier Science Ltd, Oxford, 2009)
The bimetallic [Ni-2(H(2)L2)(2)](ClO4)(4) (1), [Ni-2(HL2)(H(2)L2)](ClO4)(3) (2) and [Zn-2(H(2)L2)(2)](BF4)(4) (3) complexes (H(2)L2 = N',N'(2)-bis[(1E)-1-(2-pyridyl)ethylidene]propanedihydrazide) were synthesized and ...
