3D-printed ceramic tiles will save coral reefs from extinction

For many years coral reefs are under threat of extinction. The solution to this problem was proposed by scientists from Hong Kong University. Using the technology of 3D printing, they have created a special mosaic tiles to be placed on the bottom of shallow areas.

As a result you can create a structure that resembles a natural reef. But coral polyps are free to colonize it. The tile does not exceed a few tens of centimeters in diameter and produced on a 3D printer from terracotta clay. After high temperature firing are resistant to moisture, the elements which can be grouped in any quantity.

In the experiment, the scientists combined 128 tiles, which became the basis for the future of the reef in the Marine Park of Hong Kong. For the resulting design will follow within a few years. You can then assess the success of this approach, which in contrast to the use of analogs of metal promises the best survival rate of corals and compliance with strict environmental requirements.

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: […]
