    Trends in Aerosol Optical Depth over Indian region: Potential causes and impact indicators (2013)
    Wiley
    Details
    Publication Date: 2013-10-16
    Description: [1]  The first regional synthesis of long-term ( go back to ~ 25 years at some stations) primary data (from direct measurement) on aerosol optical depth, from the ARFINET (Network of Aerosol observatories established under the ARFI project of ISRO over Indian sub-continent) have revealed a statistically significant increasing trend with a significant seasonal variability. Examining the current values of turbidity coefficients with those reported ~ 50 years ago reveal the phenomenal nature of the increase in aerosol loading. Seasonally, the rate of increase is consistently high during the dry months (December to March) over the entire region where as the trends are rather inconsistent and weak during the pre-monsoon (April to May) and summer monsoon period (June to September). The trends in the spectral variation of AOD reveal the significance of anthropogenic activities on the increasing trend in AOD. Examining these with climate variables such as seasonal and regional rainfall, it is seen that the dry season depicts a decreasing trend in the total number of rainy days over the Indian region. The insignificant trend in AOD observed, over the Indo-Gangetic Plain (IGP), a regional hot spot of aerosols, during the pre-monsoon and summer monsoon season is mainly attributed to the competing effects of dust transport and wet removal of aerosols by the monsoon rain. Contributions of different aerosol chemical species to the total AOD simulated using GOCART over the ARFINET stations, showed an increasing trend for all the anthropogenic components and a decreasing trend for dust AOD, consistent with the inference deduced from trend in Angstrom exponent.

    Dielectric properties of epoxy resin fly ash composite (2016)
    Institute of Physics (IOP)
    Details
    Publication Date: 2016-03-05
    Description: Epoxy resin is widely used as an insulating material in high voltage applications. Ceramic fillers are always added to the polymer matrix to enhance its mechanical properties. But at the same time, filler materials decreases the electrical properties. So while making the fly ash epoxy composite, it is obvious to detect the effect of fly ash reinforcement on the dielectric nature of the material. In the present research work, fly ash is added to four different weight percentages compositions and post-curing has been done in the atmospheric condition, normal oven and micro oven. Tests were carried out on the developed polymer composite to measure its dielectric permittivity and tan delta value in a frequency range of 1 Hz - 1 MHz. The space charge behaviours were also observed by using the pulse electroacoustic (PEA) technique. The dielectric strength and losses are compared for different conditions.

    Development of Ceramic Coating on Metal Substrate using Industrial Waste and Ore Minerals (2017)
    Institute of Physics (IOP)
    Details
    Publication Date: 2017-03-04
    Description: The technological advancement in modern era has a boon for enlightening human life; but also is a bane to produce a huge amount of (industrial) wastes, which is of great concern for utilization and not to create environmental threats viz. polution etc. In the present piece of research work, attempts have been made to utilize fly ash (wastes of thermal power plants) and along with alumina bearing ore i.e. bauxite, for developing plasma spray ceramic coatings on metals. Fly ash and with 10 and 20% bauxite addition is used to deposit plasma spray coatings on a metal substrate. The surface morphology of the coatings deposited at different power levels of plasma spraying investigated through SEM and EDS analysis. The coating thickness is measured. The porosity levels of the coatings are evaluated. The coating hardness isalso measured. This piece of research work will be beneficial for future development and use of industrial waste and ore minerals for high-valued applications.

    Influence of Temperature on Pyrolysis of Biomass (2018)
    Institute of Physics (IOP)
    Details
    Publication Date: 2018-04-11
    Description: The Antimicrobial and anti-inflammatory nature of the castor oil is used for the treatment of constipation and also used to clean the intestine before a surgical treatment. The growing demand castor oil due to its cheaper price and have much demand to grow hairs faster which give proteins to hair and increases the life span of hair and increases the hair capacity and provide hair smoothness because it has high ricinoleic ratio which is beneficial for skin and hair. The main objective of this paper is by observing its usefulness and the current aim for the research work is to produce bio-char/carbon compounds and extraction of higher carbon content. The castor leaves are collected and dried in the sun light to get it moisture free and proximate analysis is studied that reveals 14% of fixed amount of carbon. The dried leaves of castor plant are pyrolized at different temperature ranges 250°C, 350 °C, 450°C, 600°C and 900°C. The pyrolised specimens were studied by Fourier-transform...

    Sea water Corrosion of Nickel based Plasma Spray Coating (2018)
    Institute of Physics (IOP)
    Details
    Publication Date: 2018-04-11
    Description: Different types of erosion resistant coatings are applied/deposited on aero components, depending on the operating/working temperatures. Nickel based coating are applied on the air craft (compressor) components, which can sustain up to working temperature of 650°C. In the present investigation, to improve the compatibility between substrate (i.e. the machine component) and the top coat, application of bond coat is there. The application of Nickel based coating by thermal plasma spray technique has proven to be a satisfactory means of producing acceptable sealing surface with excellent abradability. Before the corrosion study, coated sample is subjected to hardness, thickness and porosity testing. Hence the result is being evaluated. The corrosion behavior of coating was studied by sea water immersion with a time period of 16 weeks. It is observed that, up to 9 weeks increase in weight of coating occurs in a sharp trend and then takes a decreasing trend. The weight gain of the sa...

    Effect of carbonization temperatures on biochar formation of bamboo leaves (2018)
    Institute of Physics (IOP)
    Details
    Publication Date: 2018-04-11
    Description: Bamboo is a typical plant native in Asia, been used in many sectors, which also produces a large volume of leaves which goes waste and not find its application for any useful purposes; is often considered as a bio-waste and normally incinerated or dumped; as its applications are not yet fully explored. However, some research work done on bamboo fibers for use as a reinforcement in making polymer matrix composite. In the present piece of research work, the influence of burning/carbonization of bamboo leaves (at different temperatures) have been studied and characterized. Proximate analysis gave the fixed carbon content (of ~nearly21%). X-Ray diffraction results revealed the presence of various phases viz. cristobalite (SiO 2 ), Calcite (Ca 2 O 3 ) etc. accompanied with changes in crystal structures. Fourier transform infrared spectroscopy results showed various modes of vibrations viz. O-H stretching bending of other bonds; (for aromatic benzene derivat...
