How has nanotechnology become so important in recent years? This article will show you how necessary it is and help you understand the concept in general.
Have you heard about nanotechnology before? You probably heard about the term, but you never got to research the subject more profoundly, did you? We’re here to help you understand this vital subject.
What Is Nanotechnology?
Nanotechnology can be considered a set of activities or mechanisms that occur on a tiny scale but have real-world implications. But what would these mechanisms be? They are beyond the perception of human eyes and operate on a so-called nanometer scale.
One of the nanotechnology principles is the construction of structures and new materials from atoms. They aim to craft stable and better designs than they would be in their “normal” form.
If you are reading this article and want to learn more about another technology, here is a free eBook on Data Science, a multidisciplinary field of study that encompasses data, algorithms, and technologies capable of extracting value from structured data. With it, you will undoubtedly stand out in the job market!
How Did Nanotechnology Come About?
In 1959 it was the first time that the American physicist Richard Feynman spoke about nanotechnology, where he briefly commented on this technology’s concept. He highlighted the power of the possibility of manipulating atoms and molecules, which would result in small components that would not be possible to visualize with the naked eye.
A few years later, scientists Gerd Bering and Heinrich Rohmer created a tunneling microscope to encourage nanotechnology. When this happened, the microscope was advanced because it did not require light and also worked through the tunnel effect, allowing the visualization of individual atoms and molecules.
In addition, nanotechnology research has increased significantly. Did you know that electronic components, especially processors, are the ones that use technology the most? It is already possible to find 45-nanometer processors on the market which have high technology, to work at high speed.
What Are The Benefits Of Nanotechnology?
Nanotechnology is present in our daily lives, such as in sunscreens, sports shoes, cell phones, fabrics, cosmetics, automobiles, and medicines, among others; it is also very active in several sectors, such as energy, agriculture, treatment and remediation water, ceramics and coatings, composite materials, plastics, and polymers, etc.
Its nanoparticles can also catalyze chemical reactions, reducing the number of catalysts used to produce the chemical reactions needed in the industry. This saves money and even reduces the pollutants released into the atmosphere.
What Are The Dangers Of Nanotechnology?
Did you know that it can be harmful to the environment? Nanomaterials, or nanoscale materials, hold great promise for medicine, electronics, water treatment, and various other fields.
However, when synthetic materials are designed without critical information about their environmental impacts early in the process, their long-term effects can undermine these advances or cause what was believed to advance to become problems.
Nanotechnology can also be toxic in certain situations, as there is a lack of information to consider the impacts caused on the environment, which can mean unintended consequences go unnoticed.
However, there is a problem with applying nanotechnology to everyday products. Food, clothing, and cosmetics may contain nanomaterials without the public’s knowledge, which could pose a problem for large companies using this technology.
How Is Nanotechnology Applied Today?
Currently, nanotechnology encompasses several research areas from the most varied sectors of industry and strategic regions. Its development is significant, considering that the industry competes directly in search of new products and a better economy.
This competition will become successful when innovative products and processes emerge that compare or surpass the products offered by international industries.
