AEROGELS – A VALUE ADDITION TO HARVEST SOLAR ENERGY
Abstract: Aerogels are a class of synthetic porous ultralight material that was created in 1930 and derived from a gel, in which the liquid component has been replaced with a gas without collapsing the gel structure by freeze-drying. It is made of silica, but carbon, iron oxide, gold, copper, polymer etc. can also be used. During freeze drying the liquid in the gel is slowly dried off without collapsing the solid …

Potable Water Quality Analysis of Akbarpura, KPK, Pakistan
Abstract: In Pakistan, supply of safe drinking water of international standard is very limited. Only around 30% population has access to piped drinking water, which has rarely been completely tested for health safety. About 70% population is drinking water of unknown quality. The only testing comes through human consumption and getting sick. This study is designed to investigate the water quality problems of Akbarpura, Khyber Pukhtunkhwa. Samples were collected from the …

Influence of Catalyst Type and Reaction Conditions on Biodiesel Conversion of Pine and Soapnut Oils
Abstract: Biodiesel produced from non-edible oils is becoming an important replacement for petroleum diesel because it is renewable, environmentally friendly, and suitable for use in existing diesel engines. It helps reduce air pollution, lowers dependence on fossil fuels, and supports sustainable energy development. Pine oil and soapnut oil are two promising non-edible feedstocks because they are easy to obtain, inexpensive, and contain chemical compounds that can be effectively converted into biodiesel. …

Groundwater Quality and Its Suitability Assessment for Irrigation and Drinking in Different Aquifers of Faridpur, Bangladesh
Abstract: Abstract Thirty five groundwater samples were collected to appraise the chemical constituents in order to classify them on the basis of their suitability for irrigation and drinking. The considered water quality parameters are pH, EC, TDS, calcium, magnesium, sodium, potassium, iron, manganese, boron, sulphate, bicarbonate, chloride, sodium adsorption ratio, residual sodium carbonate, soluble sodium percentage, Kelly’s ratio, magnesium percentage and hardness. All the water samples were neutral to slightly alkaline …

Bionanocomposites in Green Synthesis of Bioplastics - The Composite Materials of Future & Their Role in Circular Bio-Economy
Abstract: The pervasive use of petroleum-derived plastics has caused severe environmental pollution, accumulating in landfills and oceans while threatening human and animal health. This ecological crisis has accelerated an urgent transition toward biodegradable polymers within the circular bioeconomy. Bionanocomposites, comprising a biodegradable polymer matrix integrated with nanoscale fillers, successfully bridge the gap between high industrial performance and environmental responsibility. By incorporating advanced nanofillers such as cellulose nanocrystals, chitin nanofibers, layered silicates …

Review on Histological Effect of Lead on Liver and Kidney
Abstract: Our environment can be polluted by environmental toxins which are chemicals and other materials produced largely from industry and its products. There are large numbers of environmental toxicants which are potentially harmful to health. These large numbers of environmental toxicants can be divided into three major categories (heavy metals, air pollutants, and pesticides) and they are commonly studied environmental toxicants. Environmental toxins can be entered into the body by various …

Corrosion and Corrosion Protection of Cast iron due to Bio-organism
Abstract: Cast iron is a high tensile strength metal. It is generally used for making tools, pipe fitting, electrical fitting equipment and rail track. It interacts with corrosive substances to develop electrochemical cell on their interface. Corrosive substances are acids, bases, salts, bio-wastes, particulates and pollutants. These substances produce hostile medium for materials. These harmful wastes discharge by industries, households, agricultural, urbanization, development of infrastructure, construction works, thermal power stations, hydropower, …
