INDIA TO BUYS CRUDE OIL FROM RUSSIA   India is buying crude oil from Russia   Indian oil corporation and Bharat petroleum had already bought the crude oil  Russia is selling its crude oil at a discount rate IOC and BP  had already bought 2 million barrels and 1 million barrels Indian oil companies are buying oils from Russia as they are selling its oils at a low rate due to the sanction held by America and western countries due to the invasion of Russia on Ukraine Indian oil and Bharat Petroleum limits had already bought 2 million and 3 million barrels of crude oil from Russia and given a tender for buying another 1 million crude oil with the transport Russia indeed needs this contract due as the invasion is going on. when the invasions starts all their exports stops due to the sanction held by the EU and North American countries. India is buying oils despite the opposition from the EU and America. Experts say India can control the price hike in petrol and ...

 SCANNING ELECTRON MICROSCOPE It is used for the surface characterization of materials. It produces images of a sample by scanning the surface with a focused beam of electrons. It provides information about topography(surface features), morphology (shape and size), composition, and crystallographic information. PRINCIPLE The electrons interact with the atoms in the sample, producing various signals that contain information about the surface topography and composition of the sample.  The accelerated electrons in an SEM carry significant amounts of kinetic energy, and this energy is dissipated as a variety of signals produced by electron sample interactions. Backscatter electrons are incidental electrons reflected backward which provide composition data related to element and compound detection. Diffracted backscatter electrons determine crystalline structures as well as the orientation of minerals and micro-fabric, X-rays emitted from beneath the sample surface, can provide ele...

 GAS CHROMATOGRAPHY It is used for the separation as well as analysis of gaseous mixture and volatile organic compounds. Principle The components of a mixture are separated depending upon the extent of adsorption or partition of the stationary phase and at the rate at which the component is carried out by the mobile phase.  The mobile phase is a gas like Argon, Nitrogen, Helium, or hydrogen. The stationary phase may be solid or liquid. If the stationary phase consists of a solid material like silica, alumina, then chromatography is termed as Gas Solid Chromatography (GSC), and if the stationary phase is a liquid held as a thin layer on a solid support, then the technique is known as Gas-Liquid Chromatography (GLC)GSC- adsorption. GLC- partition INSTRUMENTATION  Carrier gas: It is allowed to flow through the system, carrying the sample in the vapor state through the column. It should be chemically inert, suitable for the detector employed, it should give the best column pe...

OPERATION GANGA ' INDIA TO SENT C17 GLOBEMASTER III The Indian government had ordered their airforce to join the operation Ganga which is to rescue the Indians who are trapped in Ukraine  The Indian airforce comes with their C17 Globemaster3  for the rescue mission which joins with the flights of Air India, Indigo, and Spicejet  C17 Globemaster 3 can carry 381 people or more in a single flight. This military transport is so heavy that it can even carry two main battle tanks with them and carry 100 soldiers fully equipped. Indian airforce is currently operating 11 of these military transport vehicle The first flight is on 2nd March IST at 4AM from Delhi to Romania  When these flights fly to Romania the Indian government is sending medicines for the Ukraine people who are injured by the war 

"MISSION GANGA NOT UP TO THE MARK," SAYS THE STUDENTS "Mission Ganga is not efficient and not up to the mark," says the students. The Indian embassy at Keiv is not coordinating anything that the Indians need when they are trapped on the battlefield.  The Indian embassy is not providing any travel ways or rescue missions with the joining hands of the native government  The mission is aligned with Hungary, Poland , Romania, and the Slovak republic. The students in KYIV and KARKEIV are in danger. Poland and all the other country is too far away from these place if the Indian government-aligned and opened the border of Russia it would be more useful for the rescue mission.  It will be too hard to travel 1500km to reach the Poland border in a country marshal law is initiated and it is literally impossible without any strategic support from the native government. Still, there are thousands of students trapped in the capital Kyiv 

 HIGH-PERFORMANCE LIQUID CHROMATOGRAPHY It is a method used for the separation, purification, and identification of various nonvolatile high molecular weight organic compounds and natural products like cholesterol, terpenoids. ADVANTAGES High-speed separation Excellent column separation Solvent consumption is minimum Sensitive and accurate Separation can be done at an ambient temperature. PRINCIPLE The components of the mixture are separated depending upon the extent of adsorption and partition on the stationary phase and the rate at which the component is carried by the mobile phase. The mobile phase is liquid and the stationary phase can be solid or liquid. INSTRUMENTATION Solvent reservoirs are used to collect the different solvents. Pressure pump to apply pressure  Sample injector to give the mixture which is to be separated in the analytical column Regulator to adjust the flow rate Guard column to remove the particulate matter and contaminants from the solvent. The analyt...

 THIN LAYER CHROMATOGRAPHY It is a chromatographic separation method used to separate mixtures, to check the purity of a mixture, and to monitor the progress of the reaction. Procedure A glass plate coated with a material of the adsorbent will constitute the stationary phase. The material is made into a slurry or a paste and the glass plate is coated with it by a thin layer applicator and dried. This glass plate with a thin layer of stationary phase is called chromatoplate. The mixture to be separated is applied to one end of the plate and it is placed in the solvent. When the solvent reaches near the top, it is removed and dried. If the components are colored the spots can be readily located. If the components are colorless the dried plate is sprayed with a suitable reagent to make the spot colored. In this way, the position of the components is located and their Rf values are determined. Rf value is the ratio of the distance traveled by a component to the distance traveled by the...
