1.Polymer Coating of Explosives
The project was done by M.Sc final year students at Terminal Ballistics Research Laboratory, DRDO, Ramgarh. The The Objective of the work was to prepare RDX coated particles to reduce the sensitivity for defence applications.
Cyclotrimethylene trinitramine (RDX) is the most widely used crystalline high explosive in military applications. RDX has been commonly used as a chief explosive ingredient for ammunition ; e.g., propellants, shells, and bombs. Many factors such as crystal size, crystal shape, crystal size distribution affects the sensitivity of explosives. For bulk of applications, RDX need a pretreatment to decrease the sensitivity. By reducing sensitivity of explosives we can improve the properties of explosives. Polymer coating was developed by some researchers to reduce sensitivity of explosives.
The structural analyses of RDX coated particles with the help of Fourier Transform Infrared technique. The coated RDX particles were analysed for its sensitivity measurement. TGA/DSC results show that the explosive composition is thermally stable. The slurry coating is a useful option for coating of explosive particles for product reliability. These explosive particles are well coated with polymer matrix, confirmed by SEM study. These coated particles are used for pressable explosive composite in defence application.
2.Extraction of essential oils
M.Sc final year students of the Department of Chemistry, MM (DU) did this project on essential oils like castor oils, peppermint oil, eucalyptus oils etc. which were extracted by using n-hexane as solvent in soxhlet apparatus.
The main objective of the students was to extract these medicinal oils and to analyze their antibacterial and antifungal activity. The oils were characterised by UV-visible and IR spectroscopy. The purity of the oils were analysed by some chemical test such as specific gravity, iodine value, saponification number, acid value etc. The peppermint oils are often used for their flavor and their therapeutic or odoriferous properties and products such as foods, medicines. Castor oil and its derivatives are used in the manufacturing of soaps, lubricants, hydraulic and brake fluids, paints, dyes, coatings, inks, cold resistant plastics, waxes and polishes, nylon pharmaceuticals and perfumes. Eucalyptus oil is used as a topical application for headache due to cold, as an expectorant component of cough and cold compounds in various oral dosage forms, including lozenges and syrups, and as an inhalant in vapour baths.
3.Preparation of Sensors
Cost effective sensors were prepared by the students of the Department using Schiff base. These sensors can be used for the removal of hazardous ions from water.
The development of Schiff base sensors has received wide attention because of their extensive use in environmental monitoring and clinical analysis via rapid, accurate, reproducible, and low-cost methods. Chemically modified CPEs have frequently been employed as potentiometric sensors in trace analysis for metal ions, organic pollutants and biological substances. Most of these electrodes are operated via the ion-exchange process of the active component incorporated into the carbon paste matrix. These sensors have high selectivity, lower detection limit, and fast response time.
4.Extraction of Rose water
Rose water was extracted by using simple distillation process by M.Sc. 2nd year students. The process can easily be
employed at laboratory scale.
Rose Water is the generic term used for all the different variations of the rose flower
water obtained through different methods of extraction. Over 6,000 varieties of roses worldwide, only few are known as
oil-bearing roses that can be used for the production of high quality Rose Water. Major factors contributing to the
quality of Rose Water are:
(i) Method of production (steam distillation)
(ii) Species of roses used; fresh or dried
(iii) Region in the world where the roses were grown and processed. The method of production is an important factor for the quality of Rose Water. One way is simply mixing rose oil with distilled water. In this way the so called “Rose Water” is not an authentic Rose.The other way, which is the authentic Rose Water production method, is through meticulous steam-distillation of the fresh organic rose petals. Rose Water produced through meticulous steam distillation of the fresh rose petals has much more health and beauty benefits than rose water made by mixing rose oil with distilled water. Rose Water produced through meticulous steam-distillation of the fresh rose petals contains nutritious juices and pure rose oil
5.Synthesis of Elephant toothpaste
Students of B.Sc prepared the elephant toothpaste by using the safe chemicals. This was used to develop the foam easily by a simple laboratory technique. Elephant’s toothpaste is a foamy substance caused by the rapid decomposition of hydrogen peroxide using potassium iodide or yeast and warm water as a catalyst. The rate of reaction depends on the concentration of hydrogen peroxide. About 50 ml of concentrated hydrogen peroxide is first mixed with liquid soap or dishwashing detergent. Then, around 10 ml potassium iodide solution or catalase from baker’s yeast, is added to make the hydrogen peroxide decompose very quickly. Hydrogen peroxide breaks down into oxygen and water. As a small amount of hydrogen peroxide generates a large volume of oxygen, the oxygen quickly pushes out of the container. The soapy water traps the oxygen, creating bubbles, and turns into foam. About 5-10 drops of food coloring could also be added before the catalyst to dramatize the effect.
