Multi-functional conetworks based on cross-linked star polymers
(2010)
Three series of conetworks based on cross-linked star polymers of different architectures were prepared using group transfer polymerization. The first series of conetworks were amphiphilic, based on the hydrophobic monomer ...
Shear-induced nanometer and micrometer structural responses in nanocomposite hydrogels
(2010)
The structural responses of a polymer-clay nanocomposite hydrogel to an imposed shear field are investigated from the nanometer to the micrometer length scales. The effects of polymer molecular weight and concentration of ...
Synthesis and structural characterization of a metal cluster and a coordination polymer based on the [Mn6(μ4-O) 2]10+ Unit
(2010)
A new 1-D coordination polymer { [Mn6O2(O 2CMe)10 (H2O)4] 2.5 H 2O}λ (1 2.5 H2O) and the cluster [Mn 6O2(O2(O2CPh) 10(py) 2(MeCN)(H2O)] 2MeCN (2 2MeCN) are reported. Both compounds were synthesized by room temperature ...
Synthesis and characterization of a linear [Mn3(O 2CMe)4(py)8]2+ complex
(2010)
Two new compounds that consist of the linear trinuclear manganese(II) cation [Mn3(O2CMe)4(py)8] 2+ cocrystallizing with different counteranions (I3 -, [1]
Application of ion mobility spectrometry for the detection of human urine
(2010)
The aim of the present study was to evaluate the suitability of ion mobility spectrometry (IMS) for the detection of human urine as an indication of human presence during urban search and rescue operations in collapsed ...
Reversible hydrogels from amphiphilic polyelectrolyte model multiblock copolymers: The importance of macromolecular topology
(2010)
The association ability of model amphiphilic polyelectrolytes with multi-block architecture, i.e. ABA, BABAB, ABABABA and BABABABAB (A hydrophobic, B polyelectrolyte block) was studied in aqueous media. The gelation ...
End-linked amphiphilic polymer conetworks: synthesis by sequential atom transfer radical polymerization and swelling characterization
(2010)
Conetworks based on end-linked homopolymers and amphophilic gradient copolymers were synthesized by the atom transfer radical polymerization (ATRP) of 2-(dimethylamino)ethyl methaerylate (DMAEMA, hydrophilic monomer), ...
Structural characterization of amphiphilic polymer conetworks end-linked with the optimal amount of cross-linker
(2010)
Amphiphilic polymer conetworks were synthesized by the end-linking of ABA triblock copolymers using optimal (minimal) amount of cross-linker in pursuit of nanoscale phase separated materials with a long-range order. ...
Low-temperature catalytic decomposition of ethylene into H2 and secondary carbon nanotubes over Ni/CNTs
(2010)
The present work reports on the production of H2 and secondary carbon nanotubes (CNTs) during catalytic decomposition of ethylene over a novel catalytic system, namely, nickel supported on carbon nanotubes (Ni/CNTs) at ...
