Soft Matter, 2011, 7, 4147-4151. High-throughput evaluation of interactions between biomaterials, proteins and cells using patterned superhydrophobic substrates
We propose a new low cost platform for high-throughput analysis that permits screening the biological performance of independent combinations of biomaterials, cells and culture media. Patterned superhydrophobic flat substrates with controlled wettable spots are used to produce microarray chips for accelerated multiplexing evaluation.

Soft Matter, 2010, 6, 5868-5871. Bioinspired Methodology to Fabricate Hydrogel Spheres for Multi-applications Using Superhydrophobic Substrates
Inspired by the rolling of water drops over the lotus leaf, we propose a new biomimetic fabrication process for hydrogel and polymeric spheres over a superhydrophobic substrate. This method may be potentially applied in tissue engineering or as support for cell expansion,cell encapsulation and as spherical structures for controlled release of molecule.

GLASS TRANSITION BEHAVIOR OF THE SPIN-COATED THIN FILMS OF A HYDROPHILIC POLYMER ON THE SUPPORTED SUBSTRATES
Using ellipsometry, we found the glass transition temperature of the spin-coated polyacrylamide (PAL) thin films on the supported silicon (Si) substrates with an oxide layer decreases with decreasing the film thickness. But Tgs of the as-prepared thin films are much higher than that of the bulk sample. Such observations may be attributed to the combined result of the “surface effect” and...

Monitoring extent of curing and thermal-mechanical property study of printed circuit board substrates
Precise control of curing conversion for epoxy-based printed circuit board (PCB) substrates and clarification of curing-property relationship are critical for the performance and reliability assessment, and for the design optimization of electronic systems. In this article, various epoxy composites for PCB substrates were analyzed by infrared spectroscopy (IR), differential ...

Galvanic Replacement Approach for Bifunctional Polyacrylonitrile/Ag-M (M=Au or Pd) Nanofibers as SERS-active Substrates Monitoring Catalytic Reaction
SERS has been applied to monitor different types of catalytic reactions on the surface of metal NPs in recent years, which requires bifunctional metal structures with plasmonic properties as well as catalytic activity. Monitoring catalytic reactions with SERS technology in previous reports was usually performed in metal solution, using metal electrodes or on a glass/silica substrate with an immobi...

Surface-enhanced Raman Scattering-active Substrates of Electrospun Polyvinyl alcohol/gold–silver Nanofibers
Surface-enhanced Raman scattering (SERS)-active substrates of polyvinyl alcohol/gold–silver (PVA/Au–Ag) nanofibers were prepared using a simple approach involving electrospinning. The tunable surface plasmon resonance (SPR) of gold–silver alloy (Au–Ag alloy) nanoparticles (NPs) was achieved by controlling the feed ratio between gold and silver precursors. A higher concentration of Au–Ag alloy...

53. Crystal Pattern Formation and Transitions of PEO Monolayers on Solid Substrates from Nonequilibrium to near Equilibrium
The crystal pattern formation and transition of the monolayers of a low-molecular-weight poly(ethylene oxide) (n = 5000 g/mol) on the surface of silicon wafer were studied using atomic force microscopy with a hot stage in the temperature range 25 ≤ Tc ≤ 59 °C. Our observations show that the crystal patterns are greatly dependent on the crystallization temperature, Tc. At 25 ≤ Tc <...

50. Spontaneous and Inductive Thickenings of Lamellar Crystal Monolayers of Low Molecular Weight PEO Fractions on Surface of Solid Substrates
Crystalline macromolecules form folded-chain lamellar and metastable crystals. Annealing at a temperature below melting point results in a thickening of the metastable crystals to construct more stable ones. Such a process was visualized by AFM equipped with a hot stage in monolayers of poly(ethylene oxide) lamellar crystals on a silicon wafer surface. Our observations show that the monolayer...

Abnormal current– voltage characteristics and metal– insulator transition of amorphous Fe-doped carbon films on Si substrates
Amorphous Fe0.05–C0.95 films have been deposited on n-type Si substrates using direct current magnetron sputtering. The structure and electrical properties of the films/Si are investigated. The film/Si deposited at room temperature exhibits abnormal current–voltage (I–V) characteristics, whose current
increases slowly at first, and then increases to a very large value when the v...
