The linear thermosensitivity of colloidal crystals immobilized in a copolymer hydrogel film composed PNIPAM and PNMAM could be enhanced by chemically binding them on glass substrate using silane coupling agent.

in this study, the effect of nanoclay particles content on the physical properties and flammability of composite made of high density polyethylene and wood flour was investigated. for this aim, wood flour was combined with hdpe at 50% by weight, and nanoclay was used in 0, 2, 4 and 6%, also 2% of mape as the coupling agent was used in all formulations. the samples were made in injection molding...

The present study attempts to incorporate methacrylate-based polymers into ordered lamellar organic/inorganic nanocomposite films composed of alternating SiO2/polymer layers. The films are prepared by dip-coating from a solution containing the monomers and silica precursors, thus leading to composite lamellar mesostructured materials through evaporation-induced self-assembly (EISA). A polymeriz...

This study evaluated the effect of air drying temperature and different silane coupling agents on the bond strength between glass fiber posts and composite resin core. The post surface was cleaned with alcohol and treated with different silane coupling agents, being three prehydrolyzed silanes [Silano (Angelus), Prosil (FGM), RelyX Ceramic Primer (3M ESPE)] and one two-component silane [Silane ...

BACKGROUND Chemical bonding of the drug onto surfaces by means of spacer molecules is accompanied with a reduction of the biological activity of the drug due to a constricted mobility since normally only short spacer molecule like aminopropyltrimethoxysilane (APMS) are used for drug coupling. This work aimed to study covalent attachment of heparin to titanium(oxide) surfaces by varying the leng...

This paper is concerned with sequential decision making by self-interested agents when their decision processes are largely independent. This situation can be formulated as a stochastic game which would traditionally be represented in extensive form (a single game tree), a representation that fails to exploit the loose coupling in the game. We propose a new representation for 2-agent loosely co...

This paper presents a fully automated procedure for controller synthesis for multiagent systems under coupling constraints. Each agent is modeled with dynamics consisting of two terms: the first one models the coupling constraints and the other one is an additional bounded control input. We aim to design these inputs so that each agent meets an individual high-level specification given as a Met...

Theoretical arguments and empirical evidence in neuroscience suggests that organisms represent or model their environment by minimizing a variational free-energy bound on the surprise associated with sensory signals from the environment. In this paper, we study phase transitions in coupled dissipative dynamical systems (complex Ginzburg-Landau equations) under a variety of coupling conditions t...

This paper presents a study of the dynamic coupling between a user and a virtual character during body interaction. Coupling is directly linked with other dimensions, such as co-presence, engagement, and believability, and was measured in an experiment that allowed users to describe their subjective feelings about those dimensions of interest. The experiment was based on a theatrical game invol...

The synthesis of a cyclic peptide-Gd(III)DTPA molecule equipped with biotin is presented, yielding a well-defined multivalent MRI contrast agent after its coupling to avidin.
