Lithium-ion Battery Recycling   Introduction and uses: Lithium-ion batteries are amongst the most commonly used in the world, with the usage varying from handheld small electronic devices such as electronics, toys, wireless headphones to electric cars and energy storage systems we use today. These batteries are greatly preferred due to their high energy density, i.e. the ability to store energy efficiently in a given amount of space. Lithium batteries are smaller and lighter than other types of batteries, and have a greater energy density, leading to its greater use compared to other kinds of batteries. Lithium cells are of two types- one made of lithium metal which are single use and non-rechargeable, and the other which are made out of lithium and polymer and are multi use and non-rechargeable.   Structure of a li-ion battery: A lithium-ion battery comprises of a cathode, an anode and an electrolyte. The anode is usually made of carbon(graphite), the cathode of a metal ox

  Introduction:   The advancement of technology has led to the development of electronic devices that are becoming increasingly complex and powerful. However, with this increase in power comes an increase in heat generation, which can lead to device failure if not managed properly. This is where heat sink materials come into play. In this blog, we will discuss the findings of a recent study titled "Numerical Investigation on Heat Sink Material for Temperature Control of Electronics" and how it contributes to the field of thermal management. Background:   The study was conducted by Shankar Durgam, Bharati Ghodake, and Suhas Mohite from the Department of Mechanical Engineering at the College of Engineering Pune in India. The researchers investigated different heat sink materials for their effectiveness in enhancing heat transfer and cooling electronic devices. The cooling medium used for analysis was water. Findings: The study found that advanced heat sink materials can signifi

  INDIAN RAILWAY: LIFELINE THE TO NATION   Chapter 1: The Rise   On April 16th, 1853 (Chaitra Shukla Saptami, Shake 1775) , a historic moment took place in India's transportation history. The first passenger train in India ran between Mumbai and Thane, covering a distance of 34 kilometers. This was the birth of Indian Railways, which today stands as one of the largest railway networks in the world. As we celebrate the 170th anniversary of this significant event, let us take a journey through the history of Indian Railways.                 Pic Credit: The train, travelling from Bori Bunder (CST) to Tannah (Thane), left the station at precisely 3.30 pm on 16 April, 1853. (Photo courtesy: Pinterest)   The idea of a railway system in India was first proposed in 1832 by Warren Hastings, the Governor-General of India. However, it was only in 1844 that the first railway company, the Great Indian Peninsula Railway (GIPR), was established. The GIPR was tasked with building a

                                               Failure is another step of success   Wounded and weak. His fur bleached red from the blood. Hind legs screaming from pain and    uncertainty in his mind. The lion roars and readies himself again for yet another battle…   In the face of defeat the lion roars and beckons it to try him. Today I want to share the story of one such lion. A story about a time when he felt lost and felt the hands of defeat creeping in , slow and inevitable but found courage from the ones around him. Found  courage  to face his fear. A story of my oldest friend.   I was awake all night to prepare for an    exam we had on the next day.    The most dreaded subject in class twelfth: maths. This was just pre-board so there was very little pressure , but one such as myself always desires for a higher score even if the  stakes  are not as high. I got to the exam hall half an early but it was still filled with students of all divisions trying to cram in just one last top
