Resistive switching phenomena in Li xCoO 2 thin films
(2011)A substantial resistive switching of Li xCoO 2 mixed-conductor thin films is observed for the first time. The occurrence of possible bipolar switching in these oxide thin films is by current-voltage curves, investigated ...

Structural characterization of glassy and rubbery model anionic amphiphilic polymer conetworks
(2008)The structure of two series of model amphiphilic polymer conetworks based on the hydrophilic anionic methacrylic acid was characterized by atomic force microscopy (AFM) and small-angle neutron scattering (SANS). In the ...

Study of optical fiber structures using atomic force microscopy and scanning near-field optical microscopy
(1996)Atomic force microscopy (AFM) and scanning near-field optical microscopy (SNOM) were used to study optical fiber structures. The refractive index profile of fiber was disclosed by surface topography of etched fiber endface ...

Styrene-vinyl pyridine diblock copolymers: Synthesis by RAFT polymerization and self-assembly in solution and in the bulk
(2012)Reversible addition-fragmentation chain transfer (RAFT) polymerization along with benzyl dithiobenzoate chain transfer agent was employed for the controlled preparation of four diblock copolymers of styrene (St, less polar ...

Synthesis and characterization of hyperbranched amphiphilic block copolymers prepared via self-condensing RAFT polymerization
(2015)Four families of hyperbranched amphiphilic block copolymers of styrene (Sty, less polar monomer) and 2-vinylpyridine (2VPy, one of the two more polar monomers) or 4-vinylpyridine (4VPy, the other polar monomer) were prepared ...

Synthesis and characterization of large-core star polymers and polymer networks: Effects of arm length and composition of the cross-linking mixture
(2009)Large-core star polymers (LCSPs) and polymer networks were prepared using sequential group transfer polymerization (GTP) for the synthesis of linear poly(methyl methacrylate) (polyMMA) arms, followed by their cross-linking ...

Synthesis and characterization of shell-cross-linked polymer networks and large-core star polymers: Effect of the volume of the cross-linking mixture
(2009)Group transfer polymerization and sequential addition of monomer and cross-linker were employed for the preparation of two new polymer structures, one of a polymer network and the other of a star polymer. The synthesis was ...

Synthesis and characterization of well-defined optically active methacrylic diblock copolymers
(2012)A new, simple, and cost-effective approach toward the development of well-defined optically active diblock copolymers based on methacrylate monomers is described for the first time. Starting from the low-cost optically ...

Transforming growth factor-β modulates pancreatic cancer associated fibroblasts cell shape, stiffness and invasion
(2018)Background: Tumor microenvironment consists of the extracellular matrix (ECM), stromal cells, such as fibroblasts (FBs) and cancer associated fibroblasts (CAFs), and a myriad of soluble factors. In many tumor types, including ...
