Nanotechnology

Nanotechnology incorporates techniques that involve the structure and composition of materials on a nanoscale. Based on the nanometer, which is one billionth of a meter, it has become an exciting development in many fields. For example, scientists are working on miniature devices that can unclog arteries, detect and eradicate cancer cells, filter water pollution, and more. Its use in treating heart attack and stroke victims is garnering close attention in recent years. Researchers are developing nanocapsules for a “clot-busting” drug. The nanocapsule can target a specific clot, break open and release the medicine exactly at the site it’s needed. This is far more accurate than the traditional methods, such as when a drug is administered through an IV. Nanotechnology is also being developed to make computers much faster and smaller, with more memory. However, nanotechnology is currently too expensive to justify its use in many applications. Further research and development should reduce its cost in the future. In the field of information systems, the current technology for miniaturizing transistors and other micro-processor components might reach its limit in the next decade. New technologies, including nanotechnology, will be necessary.

Breakthrough Solid State Battery – 900 Wh/L Samsung

Samsung research was led by Yong-Gun Lee for an All-Solid-State-Battery (ASSBs). Their goal was to eliminate dendrites formation and increase coulombic efficiency. To do that they sandwiched layers of Lithium Nickel-Cobalt-Manganese-Oxide (NMC for short) mixed with a Sulfide Solid Electrolytes (SSE, show formula on screen), on top of nanocomposite-layer of Silver-Carbon. All of this is located in between a foil of Aluminum and Stainless steel as the current collectors. The idea behind this was to remove lithium foil from the mix and have all lithium atoms part of the NMC and SSE. This approach diminishes the costs of the overall battery manufacturing since handling lithium usually needs an oxygen free environment due to its high reactivity. This is important for a few reasons, in conventional lithium batteries, the anode comprised of lithium moves freely towards the positive electrode during discharge. Dendrites are formed during the charging process when lithium moves back to its initial location thanks to the free movement enabled by liquid or gel electrolyte. This is the main limiting factor of how much energy can be store in these batteries since to control this, the amount of lithium available in the system has to be caped, limiting the energy density.

How To Make a Quantum Bit

We have looked at how a transistor works, the fundamental unit of classical computers, and how a quantum computer works in theory, taking advantage of quantum superposition to hold exponentially more information than classical computers. Now we look at the practical side of making a quantum bit, or qubit. How do you put it in a state where it is stable? How do you read and write information on it? These processes are described for a solid-state qubit – a phosphorous atom in a silicon crystal substrate. Both the electron and the nucleus of the phosphorous atom can be used as qubits.

Smart Contracts: What Are They

The term “smart contract” sounds rather geeky and confusing but smart contracts are fairly straightforward to understand if explained the right way. Hang around until the end of the video and you will be able to explain them to anyone using real life examples. To understand how smart contracts work, we use examples of both normal contracts and smart contracts. By normal contracts we mean the contracts that are part of everyday life, for example real estate contracts, insurance contracts, employment contracts etc. We then compare how the normal contract is different from a smart contract using the same real life example.

What Is Quantum Physics, Exactly?

Our universe is an amalgamation of different objects following a wide spectrum of sizes, ranging from the smallest particles to the jumbo astronomical objects. being able to perceive the nature and behavior of all these sizes has been one ultimate goal of mankind since ages. But, as a single medicine cannot cure all the diseases, Similarly, a single scientific theory cannot work well at all the scales. So where we can efficiently describe the motion of a billiard ball or the motion of the planets around the Sun, using the same laws we cannot describe the behavior of smallest entities in the nature. This is where quantum physics comes into picture. But what it really is? What led to the development of this theory and how is it different from classical physics? This is Q and A and here is the answer to the ques What is Quantum Physics?
