Materials engineering is a branch of engineering that aims to create materials with specific physical properties to perform a specific task. Materials Science and Engineering (MSE) is a branch of engineering that combines engineering, physics, and chemistry principles to tackle real-world challenges in nanotechnology, biotechnology, information technology, energy, manufacturing, and other important engineering fields. Everything is made up of some sort of material. Materials scientists look into how materials work and why they break down. They discover novel ways to combine chemical elements into materials with extraordinary functional capabilities by studying the structure of matter at all scales, from the atomic to the millimetre. Other branches of engineering rely heavily on materials scientists and engineers to design and manufacture advanced materials used in products like safer cars with better gas mileage, faster computers with larger hard drive capacities, smaller electronics, threat-detecting sensors, renewable energy harvesting devices, and better medical devices. MSE is the field that is at the forefront of discovering and developing the components that make everything operate.
