This paper presents a new type of capacitor and deals with a hybrid approach where the advantages of two systems, dielectric capacitors and the ultracapacitor are combined. The objective is to increase the capacitance and the energy storage capability, while or at least preserving or decreasing the volume of the passive components. In this aim, the surface area and structural properties of ultr...

We present a thermal activated solvent bonding technique for the formation of embedded microstrucutres in polymer. It is based on the temperature dependent solubility of polymer in a liquid that is not a solvent at room temperature. With thermal activation, the liquid is transformed into a solvent of the polymer, creating a bonding capability through segmental or chain interdiffusion at the bon...

The mapping ~= 1+x~2_ 1is studied. The x,, i= 1, 2, 3, are independent random variables with common distribution. This mapping describes growth under fluctuating conditions, as may occur,e.g., in biology and economics. It also shows up in the grand canonical description of a directed polymer, bound to a wall of a random (1 + 1)-dimensional medium, in the limit where the polymer length goes to i...

Topological constraints, referred to as entanglements in the literature, dominate the viscoelastic behavior of high molecular weight polymeric liquids. To give a microscopic foundation of the phenomenological tube models which successfully describe this behavior, we have recently introduced a method for identifying the so-called primitive path mesh that characterizes the microscopic topological...

In transmission-reflection method, the microstrip transmission line coated with an organic polymer as an overlay is used to estimate the permittivity of the polymer film. Scattering parameter response of the microstrip line varies as the permittivity of the overlay or its thickness changes. The permittivity is estimated by minimizing the difference between the theoretical (computed from the ana...

        The purpose of this study was to prepare and characterize nimodipine loaded microspheres using ethyl cellulose (EC) as a carrier polymer through an emulsion solvent evaporation method. These evaluations characterized the pattern of drug release from prepared microspheres. Nimodipin loaded microspheres were prepared using an emulsification solvent evaporation method. The effect of proces...

Sandrine Martin Michael Hamilton Jerzy Kanicki* Abstract — Organic-polymer-based thin-film transistors (OP-TFTs) look very promising for flexible, large-area, and low-cost organic electronics. In this paper, we describe devices based on spin-coated organic polymer that reproducibly exhibit field-effect mobility values around 5×10–3 cm2/V-sec. We also address fabrication, performance, and stabil...

We reviewed recent advances in high-performance organic field-effect transistors (OFETs) based on organic semiconductor/insulator polymer blends. Fundamental aspects of phase separation in binary blends are discussed with special attention to phase-separated microstructures. Strategies for constructing semiconductor, semiconductor/dielectric, or semiconductor/passivation layers in OFETs by blen...
