Printed on a 3D printer biocoral surpassed his natural ancestor

Corals and algae are in close symbiosis with each other: the body of the coral is home to algae, and they, in turn, produce sugar, which feeds on the host. But what is interesting – specially printed on a 3D printer biocoral been found for algae-even more favourable than their natural ally. The scientists have a chance to solve the problem of the extinction of corals and at the same time to provide tseny source of biofuels.

Researchers from Cambridge and the University of California San Diego have developed a biocompatible algae and synthetic coral. They used the technology of rapid photopolymer print, allowing you to create objects with a precision micrometer for a few minutes. Printed biocoral is a skeleton of the “coral tissue”. It is made of polymer gel “PEGDA” with the addition of the cellulose nanocrystals. The fabric itself consists of a polymeric hydrogel based on gelatin “GelMA” – it is combined with living cells of algae and other cellulose.

Thanks to the nanocrystals and porous structure of the skeleton biocoral much better than the present, absorbs the light and sends it into the weeds. In fact, microalgae Marinichlorella kaistiae implanted into the artificial polyp, settled on it 100 times denser than in natural coral.

This technology can be further developed for use in more efficient and compact mechanisms for growing algae for biofuels. But most importantly – it can help to slow the destruction of algae and global extinction of coral.

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: […]
