Electrochemical Exfoliation of Graphene and its Characterisation

A green approach is reported for the production of few layered graphenes (FLGs) via electrochemical route utilising the benefits of anodic exfoliation process, wherein electrochemical intercalation of nitrate ions into pyrolytic graphite resulted in electrochemical exfoliation of nitrate ions-intercalated graphite electrode. The role of applied potential in intercalation and concentrations of nitric acid are well defining factors in controlling the number of layers in FLGs. The success of this approach was confirmed by FTIR, wherein smaller particles of intercalated graphite led to broader peaks due to increased interaction with light wave. The SEM images showed several layers of graphene stacked together and slightly twisted at edges. An increased exfoliation in intercalated graphite was revealed by XRD patterns. Desirable conductive properties of the FLGs synthesised makes it a viable option for utility as conductive ink

Effect of internet on the psychosomatic health of adolescent school children in Rourkela - A cross-sectional study

Objective: The objective of the study was to determine the effect of internet use on the psychosomatic health of adolescent school children in Rourkela. Methods: The study involved a population of 484 school students of Rourkela in the age groups of 13-18 years. History taking and clinical examination were done to know any existing health problem. Young people’s internet usage questionnaire” was handed over to enquire internet use practices. The parents of these children were asked to fill in “pediatric symptom checklist” to know psychological problems. Each answered questionnaire was given a specific serial number. The data collected from these matched sets of questionnaires as per serial number were analyzed using Chi-square test and ANOVA (to compare average number of health problems among the groups). A p<0.05 is considered significant. Results: It was found that more frequent internet user suffered from sleeplessness (p=0.048), increased interest in sexual activity (p<0.001), and conduct problems (p=0.013). Getting cyberbullied had statistically significant association with increased interest in sex (p=0.012), low mood (p=0.001), lack of concentration (p<0.001), anxiety (p=0.002), aggression (p=0.003), backache (p=0.001), headache (p=0.001), eye pain (p<0.001), and attention problems (p=0.017). Visiting porn sites were associated with interest in sex (p<0.001), low mood (p<0.001), lack of concentration (p=0.020), and unexplained anxiety (p<0.001). Conclusions: Frequency of internet use, cyberbullying, and visiting pornographic sites had a significant association with some physical and psychological health problems. For the victims of cyberbullying, average number inexplicable diseases/problems are significantly more than that of nonvictims (p<0.001)

Numerical Analysis on MHD mixed convection flow of Al_2O_3/H_2O (Aluminum-Water) Nanofluids in a Vertical Square Duct

In this work, we have considered steady laminar magnetohydrodynamics (MHD) mixed convection flow of an electrically conducting fluid in presence of nanoparticles while water as the base fluid in a vertical square duct. The walls of the duct are thermally insulated. In the energy equation, the effect of viscous dissipation and Joule heat is also considered. In this case, the walls of the duct are kept at a constant temperature. By using dimensionless quantities the governing equations of momentum, induction, and energy are first transformed into dimensionless equations. The velocity, temperature, and induced magnetic field profiles are plotted to analyze the effect of different flow parameters. It is found that the nanofluid motion expedite with the increase of the value of the parameters magnetic Reynolds number and Prandtl number. There are some important industrial applications and cooling shows in the industry of the current research. This study observed its importance with the view to increasing the heat transfer efficiency practical application relevant to industry and engineering issues. The issues discussed in this study have not been included in the earlier investigation for steady nanofluid flow due to a square duct. Numerical results are matched with an earlier published work and an excellent agreement between two are observed.
