Facile fabrication of networked patterns and their superior application to realize the virus immobilized networked pattern circuit

A facile route to fabricate a protein-immobilized network pattern circuit for rapid and highly sensitive diagnosis was developed via the evaporation directed impromptu patterning method and selective avian influenza virus (AIV) immobilization. The response to the 10 fg mL(-1) anti-AI antibody demonstrates that this easy and simple circuit has about 1000 times higher sensitivity compared to those of conventional approaches.     

Microfluidics assisted synthesis of well-defined spherical polymeric microcapsules and their utilization as potential encapsulants

In this article, the development of a novel technique to fabricate spherical polymeric microcapsules by utilizing microfluidic technology is presented. Atom transfer radical polymerization (ATRP) was employed to synthesize well-defined amphiphilic block copolymers. An organic polymer solution was constrained to adopt the spherical droplets in a continuous water phase at a T-junction microchannel, and the generation of the droplets was studied quantitatively. The flow conditions of two immiscible solutions were adjusted for the successful generation of the polymer droplets. The morphology of the microcapsules was examined. The efficiency of these polymer microcapsules as containers for the storage and controlled release of loaded molecules was evaluated by encapsulating the microcapsules with Congo-red dye and investigating the release performance using temperature controlled UV-VIS spectroscopy.     

Determination of the hyperpolarizability components of hemicyanine dyes by measuring the anisotropic fluorescence and second harmonic of the dyes uniformly aligned within zeolite channels

A unidirectional ensemble of hemicyanine molecules was prepared by inserting the molecules into the vertical channels of a uniformly oriented zeolite (silicalite-1) film grown on a glass substrate. Fluorescence from this sample excited with light polarized along the vertical channel was 50 times larger than that excited with light polarized orthogonal to the vertical channel direction. These vertically aligned hemicyanine dyes were used to determine the ratio of the molecular hyperpolarizability components beta(zxx)/beta(zzz) of hemicyanine.     

On Boundary Points at Which the Squeezing Function Tends to One

J. E. Fornæss posed the question whether the boundary point of smoothly bounded pseudoconvex domain is strictly pseudoconvex, when the asymptotic limit value of the squeezing function is 1. The purpose of this paper is to give an affirmative answer if the domain is in \(\mathbb {C}^{2}\) with smooth boundary of finite type in the sense of D’Angelo (Ann Math (2) 115(3):615–637, 1982).     

Macroscopic Alignment Control of Liquid Crystal Molecule in Optical Film for 3D Display

The optical film made of liquid crystal molecules can have useful anisotropic optical properties by controlling the alignment of molecules. In order to apply those films to commercial display, we have to know the way to control the thickness, appearance, refractive index, adhesion, and many properties in macroscopic scale. In this presentation, we show how can we control alignment of liquid crystal molecules in macroscopic scale and make the Film Patterned Retarder (FPR^TM) used in the polarization type stereoscopic 3D-displays.     

Exact classical solutions of nonlinear sigma models on supermanifolds

We study two-dimensional nonlinear sigma models with target spaces being the complex super-Grassmannian manifolds, that is, coset supermanifolds G(m,p|n,q)≅U(m|n)/[U(p|q)⊗U(m−p|n−q)]$G(m,p|n,q)\cong U(m|n)/[U(p|q)\otimes U(m-p|n-q)]$ for 0?p?m$0?p?m$, 0?q?n$0?q?n$ and 1?p+q$1?p+q$. The projective superspace CPm−1|n${\mathbf{CP}}^{m-1|n}$ is a special case of p=1$p=1$, q=0$q=0$. For the two-dimensional Euclidean base space, a wide class of exact classical solutions (or harmonic maps) are constructed explicitly and elementarily in terms of Gramm–Schmidt orthonormalisation procedure starting from holomorphic bosonic and fermionic supervector input functions. The construction is a generalisation of the non-super-case published more than twenty years ago by one of the present authors.     

Oxidative rearrangement of spiro cyclobutane cyclic aminals: efficient construction of bicyclic amidines

A new rearrangement reaction of spirocyclic cyclobutane N-halo aminals is described. This process, promoted by treatment of the aminals with N-halosuccinimides (NXS, X = Br or Cl), efficiently produces bicyclic amidines by a pathway involving initial N-halogenation of one of the aminal nitrogens followed by cyclobutane ring expansion through 1,2-C-to-N migration with simultaneous N-X bond cleavage.
