The formation of a patterned nanostructure in an AgCo/Pt/MgO~001! thin film is simulated by a technique of combining molecular dynamics and phase-field theory. The dislocation ~strain! network existing in Pt/MgO is used as a template whose pattern is transferred to the AgCo phase in spinodal decomposition, resulting in regular arrays of Co islands that are attracted by the dislocations. The inf...

Abstract-The asymptotic stability regions for the patterned steady-state solution in a two-particle catalytic CSTR, established by Arce and Ramkrishna (1991, A.IC1I.E. J. 37,98-l lo), are constructed using two approaches, Liapunov’s direct method and the construction of a trapping region. In addition, the trapping regions are also constructed for uniform steady-state solutions. Stability region...

Flash illumination is widely used in imaging under low-light environments. However, intensity falls off with propagation distance quadratically, which poses significant challenges for flash at a long distance. We propose new technique, named “patterned flash”, Patterned concentrates optical power into dot array. Compared the conventional uniform where signal overwhelmed by noise everywhere, pat...

Here, we describe the in-plane patterning of thin films of poly(acrylic acid) (PAA) within microfluidic channels by crosslinking with metal cations. The patterned polymer and embedded metal ions (Pb, Ba, Zn, Pd, Cu, La, or Ho) are a platform for the rapid “on-chip” growth of patterned metallic and semiconductor nanoparticles; these particles, in turn, serve as catalysts for electroless depositi...

The in vitro selection of nucleic acid libraries has driven the discovery of RNA and DNA receptors (aptamers) and catalysts with tailor-made functional properties. Functional nucleic acids emerging from selections have been observed to possess an unusually high degree of secondary structure. In this study, we experimentally examined the relationship between the degree of secondary structure in ...

to determine the suitable indices for vegetation cover and production assessment based on the remote sensing data, simultaneous digital data with field data belonging to the spring rangeland of the semirom-isfahan province were analyzed. during two years of monitoring the annual, grass, forb, and shrub vegetation cover and the total production data from 86 were collected. the global positioning...

The view that the cortical primordium is initially patterned in similar ways to the rest of the embryo has been a conceptual breakthrough. We now have a new starting point for understanding how the cortical area map is established and how maps may change and evolve. Here we review findings that signaling molecules secreted from distinct cortical signaling centers establish positional informatio...

Purpose The aim of this study was to determine the effects of patterned human periodontal ligament stem cell (hPDLSC) sheets fabricated using a thermoresponsive substratum. Methods In this study, we fabricated patterned hPDLSC sheets using nanotopographical cues to modulate the alignment of the cell sheet. Results The hPDLSCs showed rapid monolayer formation on various surface pattern width...

Patterned surfaces with special wettability and adhesion (sliding, sticky or patterned superoleophobic surface) can be found on many living creatures. They offer a versatile platform for microfluidic management and other biological functions. Inspired by their precise arrangement of structure and chemical component, we described a facile one-step approach to construct large scale pinecone-like ...

The growth of self-catalyzed ternary core-shell GaAsP nanowire (NW) arrays on SiO2 patterned Si(111) substrates has been demonstrated by using solid-source molecular beam epitaxy. A high-temperature deoxidization step up to ∼ 900 °C prior to NW growth was used to remove the native oxide and/or SiO2 residue from the patterned holes. To initiate the growth of GaAsP NW arrays, the Ga predeposition...
