Graphene has perfectly coped with the protection of the pipes from bacterial corrosion

Graphene continues to amaze scientists with its “talents”: in the near future it can be used in the fight against bacterial corrosion of metal pipes.

In wastewater treatment plants widespread sulphate reducing bacteria, which live in colonies in the form of biofilms on the surface of pipes and other equipment. Within 10 days after cleaning, the metal surfaces of the bacteria reappear in them, causing corrosion and subsequent failure.

Bacteria hit the pipe and from the inside, even though the polymer coating, they turned out to be quite well fed. Over time, these coatings become brittle, crack and their fragments fall into the water.

Researcher-School of mining and mining technology in South Dakota (USA) Govind Chilkur proposed to solve this problem, using as pipe coating graphene. In laboratory tests he found that even a single layer of graphene with thickness less than 1 nm prevents sulfatoxymelatonin of bacteria on the inner surface of metal pipes.

Given the fact that graphene is one of the most durable artificial materials, it should be used when creating the protective coating is so popular polymers.

Physicists have learned to turn plastic bottles in supercapacitors

Scientists from the University of California, riverside have developed a technology to produce components for supercapacitors from regular waste. We are talking about polyethylene terephthalate or PET, which is made most of plastic bottles. This material is from an economic point of view is significantly superior to high-tech raw materials, like graphene or carbon nanotubes. […]

Looks like a screwdriver of the XXI century

Recently Techcult wrote about the drill of the XXI century with a touchscreen and lasers. But the screwdriver is traditionally considered to be more simple, reliable and very straightforward tool. What similar high-tech screwdriver advanced Italian production? And it is similar to the Kinetic device Driver. Kinetic Driver designed by the Italian designer Giacomo Di […]

Our Solar system is most similar to space croissant

The sun emits powerful electromagnetic winds that envelop the planet in our solar system like a giant bubble. This magnetic bubble is called the heliosphere and protects the planet from dangerous space radiation. Scientists have long believed that the heliosphere is in the form of a comet – with a distinct nose and long flowing […]

Some homemade masks turned out to be more dangerous than no

Despite the fact that the industry has recovered from the shock of the first days of the pandemic COVID-19 and now produces enough facial masks of different types, most people in the world due to various reasons use homemade versions. Everyone understands that they are less effective than professional medical model, but the question is: […]
