Nowadays, the synthesis of metal chalcogenides has received wide attention because of their suitability, simplicity and cost-effectiveness for large scale deposition by the selection of suitable chemical methods. Predominantly, thin-film technology has led to large-scale deposition techniques, using the variety of substrates such as insulators, semiconductors and metals. These methods are applicable at low temperatures, reducing the chances of oxidation and corrosion of the substrate. Among the various methods, Chemical Bath Deposition is highly attractive, owing to its advantages over conventional thin film deposition method. Moreover, it does not require high temperature as well as sophisticated and expensive equipment. Most researchers focused on the metal sulphides; they have a wide range of applications like sensors, modulators, dielectric filters, LEDs, efficient phosphors in flat panel display and buffer layers in the solar cells. A comprehensive review has been attempted in this work with necessary background theory for the thin film depositions. The Chemical Bath Deposition method has been reviewed in detail to obtain well-adherent and uniform zinc sulphide thin films. Bath parameters and structural, morphological, optical, and electrical properties were highlighted.

The high performance symmetric supercapacitor electrodes were fabricated using peanut shell activated porous carbon synthesized by chemical activation method. The textural and surface morphology were analysed. The Electrochemical studies of fabricated electrodes were investigated by 6M KOH as an aqueous electrolyte using two electrodes system. From chargedischarge process, gravimetric capacitance and volumetric capacitance values were calculated such as 160 Fg and 116.8 Fcm at current density of 1 Ag in 6M KOH solution .Energy density and Power density values were calculated as 5.5 WhKg for 1 Ag and 4 KwKg for 10 Ag respectively. This electrode has excellent cyclic stability and has revealed 80% capacitance retention even after 8,000 charge/discharge cycles at 1 Ag. The result clearly demonstrated that the natural resource of specific biomass could be an economic, eco-friendly and alternative raw material for supercapacitor electrodes with efficient volumetric Energy and Power density

Natural disasters have become fast growing epidemics around the world in general, the disasters like earthquakes, landslides, floods, cyclones and other coastal hazards etc., are already crippling the development and growth of the country. In the recent decades, the “Earth Observing Satellites” which are producing unparallel pictures on various spectral, spatial and temporal resolutions, where as the fast emerging “Geospatial Technology” (GIS) has proved its credentials beyond doubt in storing, manipulating, modeling and visualizing various phenomena related to Earth System Dynamics. In this context, the present paper discusses to map the disasters like earthquakes, landslides, soil erosion, floods and cyclone on their pattern and spatial variation. The Geomatics based integrated terrain analysis, leading to the detection of landslide prone areas, causative factors, predictive models leading to the early warning system etc., Flood is yet another major disaster causing greater impediment to country, which are aspiring to grow faster. Though methodologies have been developed for flood hazard zonation mapping, the geomatics has not been utilized to its deserving levels. And concluded that the geospatial data bases which provide important inputs for studies in the emerging areas of environmental monitoring, global warming and climate change.
