Here we describe a class of electric-conducting polymers that conduct electrons via the side chain π-π stacking. These polymers can be designed and synthesized with different chemical moieties to perform different functions, extremely suitable as a conductive polymer binder for lithium battery electrodes. A class of methacrylate polymers based on a polycyclic aromatic hydrocarbon side moiety, p...

The accumulation and disposal of polymer wastes including waste plastics, waste rubber, waste synthetic fibers and waste composites is a worldwide concern. Until now, there are many technical barriers in recycling polymer wastes with crosslinked structure, such as vulcanized rubber, crosslinked polyolefine and other thermoset materials. In this study, a mechanochemical approach was used to cond...

Conjugated polymers, such as poly(3,4-ethylene dioxythiophene) (PEDOT), have emerged as promising materials for interfacing biomedical devices with tissue because of their relatively soft mechanical properties, versatile organic chemistry, and inherent ability to conduct both ions and electrons. However, their limited adhesion to substrates is a concern for in vivo applications. We report an el...

Contact thermal lithography is a method for fabricating patterns based on thermal effects. In contrast to photolithography, where resolution is limited by the wavelength of light used in the exposure process, thermal lithography is limited by thermal diffusion. A traditional metal-glass photomask is brought into contact with a wafer coated with a thermally sensitive polymer. The mask-wafer comb...

conduct disorders are a group of behavior disorders in which the basic rights of others or major age appropriate social norms or rules are violated. to evaluate the factors influencing childhood conduct disorders, we reviewed records of 43 cases (84% boys, mean age 11 years) referred to shahid esmaili psychiatric hospital, tehran. all patients fulfilled diagnostic criteria of dsmiv. 15 variable...

The authors are aware that virtually every government laboratory and agency is grappling with the problem of technology transfer to American industry. This activity is in response to the Federal Technology Transfer Acts (FTTA) of 1986 and 1989, which were conceived in an attempt to make American industry more competitive world wide. These acts in turn are a response to the fact that so many Ame...

Research Achievement Hybrid solar cells have been developed in the past decade as a promising alternative for traditional silicon-based solar cells. One approach for making inexpensive inorganic-organic hybrid photovoltaic (PV) cells is to fill nanostructured titania films with solid organic hole conductors such as conjugated polymers. These compounds can function as light-absorbing species and...

Purpose. To explore the associations and interactions among ecological factors and explain the psychosocial quality of life of children with complex needs. Methods. In this cross-sectional survey consenting parents were identified by the Children's Treatment Network. Families were eligible if the child from 0 to 19 years, resided in Simcoe/York, and there were multiple family needs. Regression ...

Sir, I read with great interest the study by Malhotra et al.(1999, 41, 111-121). This study was designed to evaluate the symptomatology and clinical variables of hyperkinetic conduct disorder (HCD) and compare it with conduct disorder (CD) and also to determine the clinical variables that can discriminate these two disorders as a validation of HCD as a category. However, this study merits certa...

objective: pmbn, poly [2-methacryloyloxyethyl phosphoryl choline (mpc)-co-n- buthyl methacrylate (bma)-co-p-nitrophenyl- oxycrabonyl poly (ethylene glycol-methacrylate (meonp)], as a biocompatible ter-polymer is a unique polymer with wide range of application from drug delivery systems to scaffolds and biomedical devices. in this research, monomer of p- nitrophenyl- oxycarbonyl poly (ethylene g...
