Eco-Friendly Corrosion Inhibition of Aluminum Alloys with Acacia nilotica in Acidic Media
Abstract: Gravimetric analysis was used to examine the corrosion inhibitory effects of Acacia nilotica extract in 0.5 N H2SO4 on aluminum alloy at different concentrations and at 303 K. At a corrosion inhibitor concentration 0.45% at 303 K, the inhibition efficiency is found to be remarkably high (52.25%). Results show that the extract's capacity to inhibit was caused by its adsorption onto the metal surface via the Langmuir adsorption process. For …

Corrosion and Corrosion Protection of Carbon Steel
Abstract: Carbon steel is a very important metal for petroleum industries. Petroleum refineries are used bulk amount of carbon steel for purification of crude oil. Some amount of carbon dioxide and sulphur dioxide present in crude oil. Both gases are acidic in nature so they generate hostile medium for metal. These gases convert into carbonic and sulphuric acid and develop electrochemical cell on the surface of metal and aggravate corrosion reaction. …

Spectrophtometric Study of Catalysed Oxidation of Some Cyclic Alcohols by N-bromophthalimide
Abstract: The spectrophotometric kinetic investigation of cyclohexanol and cycloheptanol catalysed by Keggin type anion [PW12O40]3- with N-bromophthalimide have been carried out in 30% acetic acid medium in absence of mercuric(II) acetate and in presence of sulphuric acid. The observed kinetic data was used for the justification of Beer-Lambert law. The reactions follow a fractional-order with respect to cyclic alcohols, PTA catalyst and first-order with respect to oxidant NBP. The added H+ …

Effect of Palm Sugar (Arenga pinnata) and Jaggery (Saccharam officinarum) on Qualitative Characteristics and Sensory Attributes of Ice Cream
Abstract: The Diabetic products demand has increased very fast due to awareness in consumers about the benefits of the products for sound health. It is estimated that around 8-12% of the global population buys diabetic products on regular basis. Sweeteners used to make sugar, palm sugar, and jaggery powder differ from one another. Hazardous substances such phosphoric acid, calcium oxide, sulphur dioxide, polyacrylamide, and bone char are utilised in the production …

Nanocoating and Electrospray Techniques Use to Mitigation Corrosion Sculptures
Abstract: The most sculptures of the world are created by the brass, bronze, iron, silver, gold and metalloid. They come in contact of corrosive pollutants to produce chemical, electrochemical and biochemical reactions and develop various form of corrosion like uniform corrosion, galvanic corrosion, pitting corrosion, stress corrosion and crevice corrosion. The corrosive gases CO2, NO2 and SO2 concentrations increase in atmosphere rapidly after industrialization. The major contributors of these gases are …

Invitro Studies on Isolation, Screening and Characterization of Streptokinase from Bacillus SPP
Abstract: Streptokinase have isolated from the Bacillus spp. by using fermentation. The soil sample have collected from the different area of the Lucknow. The Gram’s staining was used to determining Bacillus spp. The screening method was used for the characterization for the bacteria. The enzyme concentration measured by using Lowry’s protein estimation method. Caseinolytic activity have performed to study the enzyme activity. Many different enzymes are required to bring about the …

Comparative studies on the use of palm kernel and coconut oil as biodiesel fuel sources
Abstract: This research work focuses on the production of biodiesel from palm kernel oil and coconut oil. The biodiesel was prepared by trans-esterification of the oils (unsaturated fatty acid) with an alcohol in the presence of a catalyst to give mono alkyl ester. The biodiesel obtained from the two sources was characterized and the properties compared, The API gravity, Specific gravity, Flash point, Carbon residue, Sediment and Water content, sulphur content …
