Polymer nanocomposite composed of polypyrrole, chitosan, and zinc oxide nanoparticles has been synthesized and it has been evaluated for various electrochemical aspects of the current electrochemical industry. The polypyrrole (PPy) was synthesized by the chemical oxidative polymerization reaction by employing ammonium persulfate as oxidizing agent. Composites of polypyrrole/chitosan (PPy/Chy) and polypyrrole/chitosan/ZnO (PCZ) composites were synthesized by the solution blending method. Detailed structural, morphological, thermal characterization of PPy, PPy/Chy, and PCZ were performed to characterize the specific features of the systems. The composites exhibit better thermal stability and high surface area and the addition of ZnO nanoparticle increase the crystallinity of the composite. Electrochemical characterization of the ITO electrodes modified with PPy, PPy/Chy, and PCZ were performed using cyclic voltammetry, electrochemical impedance spectroscopy, and amperometry techniques. The present study highlights the role of a bio‐compatible material with high surface area and conductive constituent for designing of various high performing electronic noninvasive sensors, biosensors, and so forth.
Children are the worlds precious resources and the best hope for future. During clinical experiences, observation and rapport with mothers, investigators assess many children show difference in sleep patterns and irritated with daily life. The present study was aimed to assess the parental perception on sleep habit of children in the paediatric ward. Objectives: assess the parental perception on sleep habit among children and to find relationship between sleep habit and selected socio demographic variables. Methodology: Quantitative experimental approach was used with descriptive design. The data were collected from 50 children by using random sampling technique. Data were analysed using descriptive and inferential statistics. Result and interpretation: The findings of the study had shown that majority of subjects 24(48%) of the children belongs to age group of 2 to 3 years, 27(54%) were females, 25(50) of children were moderately nourished.39(78%) of children has a meal pattern of more than one hour before sleep, 60% like outdoor play, 35(70%) does not need toys for sleep. Majority of the parents 22(44%) belongs to 26-30 age group, 25(50%) belongs to females, 17(34%) were graduates, 40(80%) were healthy. we found that there is a relationship between clinical data variables such as nutritional status(p=0.041) with sleep habit of children. By using parental perception questionnaire, we found that parents have good perception on sleep habit among children as out of 50 samples 35(70%) secure good score, 14 (28%) secure satisfactory score and only 1(2%) secure poor score.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
