Physics Department, DAV (PG) College, Bulandshahr, UP, India.

 

Theoretical study of fullerene C60 and C70 via Raman Spectra method were performed to investigate the Crystal structure of fullerene C60 and C70. . Raman Spectroscopy is particularly well suited to detect small changes in structural morphology of carbon nano materials making it an indispensable tool for many material scientists working with carbon nanostructures. Structure of fullerene C60 lead to interesting application possibilities. And its derivatives such as buckyball clusters, nanotubes, megatubes, polymers, nano onions and fullerene rings have made fullerenes as an active field of research.

Keywords: fullerene, buckminsterfullerene.

Improving Child Security using GPS Enabled Identification Card – Dr. Vaibhav Jain.

Improving Child Security using GPS Enabled Identification Card

Dr. Vaibhav Jain

Physics Department, DAV (PG) College, Bulandshahr, UP, India.

 

The burst of insecurity in the country has brought an idea to develop a Global Positioning System (GPS) based tracking system to meet the increased quantity of security issues. In this paper, we present a system – the student Identity Card, which is GPS enabled. This ID card will be linked to a dedicated mobile i.e., parents mobile. A parent at any time, even from home or from his/her office can find their child’s location. Further, this concept can also be extended to implement in the vehicles with a GPS enabled vehicle chassis for the security of vehicles and to control the vehicle’s speed.

Key words: Global Positioning system, vehicle chassis.

Cadmium precursors with acetylacetonate, less toxic than Me2Cd give one-step synthesis procedure for CdSe quantum dots (QDs). Powder X-ray diffraction shows hexagonal structure of QDs. TEM and HRTEM images of QDs reveal that they are almost mono disperse and size is of the order of  5 nm. It is observed that the precursor and reaction time affect size. The size of QDs increases with reaction time. The temporal growth was monitored by UV−Vis spectroscopy (up to 20 min).

Keywords: Cadmium selenide, X-ray diffraction, Temporal growth.

Nanotechnology has been defined as relating to material, system and processes which operate at a scale of 100 nm or less. It has interdisciplinary approaches. Nanotechnology has potential to change the entire scenario of the present food industry and agriculture with the help of nano-based technology.  Environmental pollution is threat to the world’s environment, many nano based eco-friendly tools has developed which can reduce the pollution and clean-up the existing pollutant. Nano is also playing important role in the field of medical science and veterinary science.

Key words: Nanotechnology, Food industry, Nano-particles.

Impact of Urban Air Pollution on Epidermal Traits of Amaranthus viridis Growing along the Road Side-Dr. Anita Pawar.

Impact of Urban Air Pollution on Epidermal Traits of Amaranthus viridis Growing along the Road Side

The present paper deals with the study of the impact of urban air pollution on epidermal traits. The light microscopic studies of Amaranthus viridis leaves showed marked alteration in the micromorphological parameters. Increase in the number of epidermal cells was recorded in the samples of polluted area on both upper & lower surface of leaf. But decline was noticed in stomatal frequency, dimensions of stomata and stomatal Index in stressed area leaf samples on both the surfaces. These parameters are useful as indicators of environmental stress or pollution.

 

Keywords: Epidermal traits, Amaranthus viridis, Stomatal frequency, Stomatal index.

Auto Exhaust Pollution Induced Alteration in Leaf Morphology of Some Common Road Side Plants-Dr. Anita Pawar.

Auto Exhaust Pollution Induced Alteration in Leaf Morphology of Some Common Road Side Plants

Dr. Anita Pawar

Associate Prof. & Head of Botany Department

N.R.E.C. College, Khurja, U.P. India.

 

Present paper deals with the Auto exhaust induced changes in leaf morphology of some common road side plants. The study was conducted in city Ghaziabad, three sites were selected- HPA (Highly polluted area), MPA (Medium polluted area), FA (Fresh area). Five plants – Ricinus communis (Arandi), Amaranthus viridis (chauli), Cassia obtusifolia (chakunda), Withania somnifera (ashvagandha), Calotropis procera (madar). The parameters examined were leaf length, breadth and area. Decline was recorded in the parameters considered for the study of the leaf samples collected from polluted areas. These alterations can be considered as indicators of auto exhaust pollution.

Keywords: Auto exhaust, Leaf morphology, Highly polluted area (HPA), Medium polluted area MPA, Fresh area (FA).
