The utilization of waste materials in concrete manufacture provides a satisfactory solution to some of the environmental concerns and problems associated with waste management. Agro wastes such as rice husk ash, wheat straw ash, hazel nutshell and sugarcane bagasse ash are used as pozzolanic materials for the development of blended cements. India being one of the largest producers of sugarcane in the world, produces 300 million tons per year and large quantity of sugarcane bagasse is available from sugar mills. Sugarcane bagasse is partly used as fuel at the sugar mill. In the present paper, sugarcane bagasse was burned at 600oC and the ash obtained is known as sugarcane bagasse ash (SCBA) and characterized by using different techniques. SCBA was mixed with OPC in different proportions and the hydration studies were made. Mechanism of hydration has been discussed.Keywords
Compressive Strength, Portland Cement, Bagasse Ash, DTG & FTIR.

Nanoscience first captured the world's attention when Nobel Prize winner Richard Feynman delivered his famous 1959 speech "There's Plenty of Room at the Bottom". Since Feynman's scientific call to action, nanoscience and nanotechnology have evolved into a revolutionary area of technology-based research, opening the door to precise engineering on the atomic scale and affecting everything from healthcare to the environment. This article gives an overview of Nanoscience and technology. Concept of nanoscience, its development, preparation, characterization and properties of nanomaterials have been discussed. Applications of nanomaterials in consumer products and also expected applications have been highlighted. Attentions are drawn towards risk assessment.Keywords

Hydrogen is significant and may be viewed as an alternative for main fossil fuels, coal, crude oil, and natural gas, as well as its derivatives when utilized as fuel. It has the potential to be a clean, efficient, and inexpensive energy source. The main benefit is that its oxygen-burning products are water and not carbon-containing and greenhouse gases CO and CO2. Conventional forms of energy are dependent on fossil fuels and have several consequences, namely pollution, climate change, and increased price. Promising alternatives are renewable energy sources like solar and wind energy. However, the main limitation for renewable energy sources is that they are always unavailable and provide us with interrupted energy. As a result, energy resources should be combined with energy storage devices in order to offer continuous power. This paper examines the various storage systems and concentrates on energy storage systems based on hydrogen.Keywords

Because of their various nanostructures, carbon nanotubes (CNTs) and graphene have garnered considerable attention, making it a particularly appealing and broad topic in nanotechnology. Graphene and carbon nanotubes (CNTs) both have unique electrical, mechanical, thermal, catalytic, and electrochemical features because they are made up of sp2 hybridized carbon atoms. Carbon nanotube hybrid nanostructured materials (CNT hybrid nanocomposites), Carbon nanotubes (CNTs), and nanotechnology have the potential to improve energy conversion and storage device applications. Carbon nanotubes are being evaluated for application in renewable energy sources, including solar cells and hydrogen storage. Carbon nanotubes (CNTs) are utilized in storage technologies such as Li-ion batteries, supercapacitors, and thermal energy harvesting.Keywords
