MDPI.com is a website that publishes articles written by scientists who study a wide range of topics in science. They write about things like new scientific discoveries, advances in technology, and different ways to solve scientific problems.
In order to write these articles, scientists use a lot of big words and complicated ideas that are difficult for most people to understand. But MDPI.com takes these complex topics and tries to explain them in a way that is easier for regular people, like you and me, to understand.
So, when you read an article on MDPI.com, you're essentially learning about science from some of the smartest people in the world, but they're explaining it to you in a way that you'll be able to understand. It's like having a teacher who is really good at explaining things in simple terms so that you can follow along and learn something new.
