Poly(acrylamide-co-itaconic acid) and semi-IPNS with poly(ethylene glycol): Preparation and characterization
(Wiley-VCH Verlag Gmbh, Weinheim, 2004)
A pH-responsive poly(acrylamide-co-itaconic acid) (PAAm/IA) hydrogel and semi-interpenetrating networks (semi-IPNs) with 5, 10 and 15 wt.-% of poly(ethylene glycol) (PAAm/IA/PEG), were synthesized. Their swelling behavior ...
Semi-interpenetrating polymer networks composed of poly(N-isopropyl acrylamide) and polyacrylamide hydrogels
(John Wiley and Sons Inc., 2004)
Three series of semi-interpenetrating polymer networks, baaed on crosslinked poly(N-isopropyl acrylamide) (PNIPA) and 1 wt % nonionic or ionic (cationic and anionic) linear polyacrylamide (PAAm), were synthesized to improve ...
One-dimensional random walk of nanosized liquid Pb inclusions on dislocations in Al
(Taylor & Francis, 2004)
Migration of nanosized liquid Pb inclusions attached to dislocations in Al
has been observed during in-situ transmission electron microscopy heating
experiments and monitored by real-time video recordings. The movements ...
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 ...
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 ...
Random vibration movements of liquid nanosized Pb inclusions in Al
(Elsevier B.V., 2004)
Transmission electron microscopy has been used to study the behavior of liquid nanosized Pb inclusions in Al ribbons made by rapid solidification. In situ heating experiments carried out in the temperature range from around ...
Characterization of Structure and Properties of As-cast AlCuMg Alloys
(Japan Institute of Metals (JIM), 2004)
Early stages of transformation of a metastable AlCuMg alloy have been studied by DSC, X-ray powder diffraction method, quantitative microstructure analysis, hardness, compression strength and by scanning electron microscope. ...
The elusive metastable peak.
(Wiley-Blackwell, 2004)
Prediction of ductile fracture initiation using micromechanical analysis
(Pergamon-Elsevier Science Ltd, Oxford, 2004)
In the paper ductile fracture initiation analysis of low-alloyed ferritic steel has been made by application of two micromechanical models: the Rice-Tracey void growth model and the Gurson-Tvergaard-Needleman (GTN) model. ...
