Advances in science and engineering both solve problems and create new ones—with every technological innovation, a supply chain of materials, processes, and technology is growing to capitalize on it.
FREMONT, CA: Materials science and engineering in general, particularly surface coatings, are critical for commercializing laboratory discoveries. They enable previously impossible or prohibitive tasks, such as coating light metals to make them resistant to severely corrosive and high-temperature situations. Additionally, coatings speed up the development and implementation of innovative technology.

Some trends that will dominate and influence the direction of materials and surface coatings development are as follows:
Preparedness and response to pandemics: The coronavirus crisis of 2020 demonstrated how ill-prepared most of the globe was to respond to a global pandemic, despite prior regional pandemics such as SARS, Ebola, and MERS. It also shows what an innovative, collaborative, unyielding, and resourceful species people can be when confronted with global threats.
Pandemic-driven innovation included repurposing existing supply chains and infrastructure from the manufacture of diggers to the manufacture of ventilators and the creation of a dozen world-class vaccinations in a tenth of the time it generally takes. The Manufacturer has created a database of various businesses that have shifted their primary focus to pandemic response production. The issue today is to prepare for the inevitable next pandemic.
A vast array of remedies is being developed to aid in the fight against pandemics. For instance, the European Commission alone is sponsoring more than a dozen digital health initiatives to combat pandemics, including revolutionary air purification devices, diagnostic testing, and telemedicine platforms.
Nanomaterials and nanostructures: The ability of materials to behave as waves and particles at nanoscales (1-100 nanometers) underpins the prospects given by nanotechnologies (there are 1 million nanometers in a millimeter). In materials science jargon, Nanomaterials have a high surface area to volume ratio. This results in more nanomaterial coming into touch with the surrounding materials, resulting in increased reactivity.
There are uses of nanomaterials in research that would sound like science fiction if they were not so close to commercialization. They involve nanoparticles to transport dental repair ingredients, allowing teeth to self-heal. Similarly, osseointegration of medical implants could be aided by this strategy.
For instance, a team of US and Israeli researchers has discovered a means to produce 3D superconducting nanostructures by combining DNA with superconducting niobium and silicon. DNA origami is a method that has applications in medical and geophysical sensors and quantum computing.
Additionally, incorporating titanium dioxide nanoparticles, tiny supercatalysts, into plasma electrolytic oxidation (PEO) surface coatings might impart photocatalytic capabilities on the surfaces of light metals.
