The authors report a novel detection technique for two types of common heavy metal contaminants in water, copper sulphate and ferric chloride, by analyzing the transmittance measurement of a supercontinuum laser source on the samples. In the past, the detection of heavy metal contaminants in water was done conventionally by using atomic spectroscopy method. This method requires a series of steps such as atomization of water sample by burning the sample with flame and then shines a specific wavelength of light on that cloud of atoms in order to determine the presence of that particular heavy metal contaminant. The authors aim to demonstrate a more convenient method, which is by shining a broadband supercontinuum light source directly on the water sample and performing transmittance measurement. Instead of shining a light source with certain wavelength, supercontinuum laser source allows emission of light ranging from 600 nm to 1600 nm wavelength simultaneously. By measuring the amount of light transmitted through the water sample, the concentration of heavy metal contaminants can be determined. The laser source, which comprises of a Master Oscillator Power Amplifier (MOPA) paired with a 15 meters long Photonic Crystal Fiber (PCF) has the ability of producing broad bandwidth light source with an average power of 1W. The experimental results were further analyzed using Analysis Of Variance (ANOVA) in which, the authors have identified that wavelength, concentration of heavy metal contaminants and the types of contaminants that will affect the transmittance of the supercontinuum laser source.
Chemical Engineering is the distinct branch of the Engineering profession. Chemical engineering activity is mainly concerned with the exploitation of chemical reactions on commercial scales. Chemistry is one of the basic and important subjects to build the best chemical engineers. The basic aim of the present work is to understand the 3rd year chemical engineering students’ approaches, observations and outlooks towards chemistry and chemical engineering subjects they learnt. They learn 3-4 chemistry subjects in 1st year and 2nd year of chemical engineering and almost all major chemical engineering subjects. Certain questionnaire was formulated to collect the respective data. The data of 64 students of chemical engineering have been collected and analyzed with respect to their experience of chemistry learnt in the first and second year of chemical engineering and its concerns for chemical engineering. The results are presented in terms of bar charts and exhuastively interpreted. Overall, the results suggest that, the students’ experience for urban students is better than the rural student in all aspects. Further, more specific teaching – learning system should be developed to create the interest of the students in chemistry and so on chemical engineering.
Biomechanics is a field that combines with disciplines of Biology, Engineering Mechanics, and Mathematics, utilizes the tools of Physics, Computer Aided Design, Computer Aided Manufacturing, and Engineering to describe the properties of biological materials. These measurements are used to estimate the fracture risk in people of all ages. The theme of this present work is to carry out the finite element analysis of femur bone during the static condition. Finite element analysis has been widely used to describe the mechanical behavior of the long bones, which have been created from CT (Computer Tomography) images. In this work, a three dimensional model of the human femur bone has been modeled by using Bio-CAD software and analysis is done by using COMSOL Multiphysics software. This method helps to find out risk factor in bone fractures and finds a region of fracture zones.
In the present scenario, Nanophysics and Nanochemistry are relatively new areas of science arisen in the last decade after the discovery of fullerenes and nanotubes. Nano sized materials are used in numerous applications ranging from electric storage device, science and engineering, which will bring a wave of radical innovation .

This paper describes introduction to the most interdisciplinary integrated modern science known as nanotechnology. Classification and properties of nanomaterials, synthesis of Nanomaterial, and its growth, significance, applications in various fields. The new material terminologies associated with this field. This paper gives a short overview of some of the different types of nanomaterials such as graphite, fullerenes and carbon nanotube, etc.
One of the most important environmental problems faced by the world is management of wastes. Industrial processes generate a variety of molecules that may pollute air and waters due to negative impacts such as Toxicity, Carcinogenic and Mutagenic properties. The aim of the present paper is, it provides an outline of the Physico-Chemical characteristics, hazards and remediation measures for control of phenol toxicity. Phenol and its components are extremely toxic and can be easily be isolated from different industrial sewage such as oil refinery, petrochemical industry and mines, especially collier and chemical factories. Hence, the presence of these compounds in the environment could cause environmental pollution, especially in water resources. The purpose of the study is crucial to perpetuate the environment and individual. Various methods are recommended for removal of the phenol from wastewater include physico-chemical and biological like steam stripping, solvent extraction, adsorption, chemical oxidation and biodegradation methods are discussed. The work reported in this study is, the complete removal of the pollutants by the use of physical and chemical processes is not possible. Critical appraisal of the literature reveals that, biological treatment is economical, practical and the most promising and versatile approach as it leads to complete mineralization of phenol producing non toxic end products.
