10 impressive scientific and technological inventions

The world of science - technology last week was filled with sparkling colors, from glowing mice, invisible wireless networks to projection chocolate.

In this photo, the mouse glows under ultraviolet light. Expert Warren Chan of the University of Toronto (Canada) injected nanoparticles called "quantum dots" to observe the process of tiny particles forming inside internal organs and skin after absorption. Since then, he has been able to draw conclusions about the accretion in the bodies of particles in commercial products, including food packaging, water treatment chemicals, pesticides and cosmetics.

2. Electric aircraft

Airbus is testing a new model called E-Fan, which runs a gasoline-electric hybrid engine. The goal is to build electric aircraft with a capacity of 70 to 90 passengers for regional routes.

3. Water particle system

While the world warms and the desert is expanding, water becomes more scarce. An important study conducted by US National Laboratory experts at Oak Ridge has found a way to build a water particle system model that makes them impossible to combine in the air.

This technique can help make devices that harvest dew from the air and reuse it as drinking water.

4. Solar table lamp

Sub-Saharan Africa lacks basic infrastructure to produce and use electricity. Most people use generators that run in kerosene, discharging harmful gases. Bloomberg has invested $ 5 million to bring solar-powered table lamps to some of its communities.

5. Robotic exploration of harsh environments

Humans have sent ships to travel to the moon, Mars, but to expand the scope of exploration to other planets in the solar system, scientists need to build robots that are resistant to the environment. extremely harsh.

At Keio University (Japan), experts are focusing on three areas: interactive vehicle mechanics, self-propelled mobile systems and robot equipment. The goal is to create autonomous adventurous robots in unprecedented worlds and in unusual environmental conditions.

6. 'Ghosts' in the machine

British photographer Luis Hernan has found a way to force the invisible infrastructure inside wireless networks to be 'embodied'. Accordingly, the project called Digital Spirit is primarily based on the Kirlian device, which scans wireless networks and interprets signal strength into LED colors. The visual effect is very impressive, allowing viewers to see the 'ghosts' inside networked machines.

7. In shark skin

For the first time, scientists have found a way to print shark skin. George Lauder and colleagues at Harvard University (USA) used 3D printing techniques to recreate the tiny structures called 'small serrations' that form unique patterns on shark skin.

Since printers cannot form structures at a micro level like in nature, artificial leather is printed of course, much larger than real leather. However, when tested in a water environment, the 'small jagged' images still mimic the hydrodynamic mechanism of true shark skin.

This material can boost the study of sharks and even surfaces that move in water with minimal friction.

8. Air cushion bicycle

Aerofex has been testing equipment called air-cushion bicycles since 2012. Now, the company is finalizing the final stage before launching the complete product to the market. According to the new statement, Aerofex said it would start selling the commercial version of Aero-X for $ 85,000 in 2017.

9. Chocolate projection

Switzerland is clearly the leading country in chocolate. Chocolatier Morphotonix, based in Lausanne, has introduced a new type of chocolate capable of refracting light and creating vivid projected images. This technique is similar to the way projection technology is integrated into plastic credit cards, except that it is edible and safe.

10. Tesla's Model X

One of the most appealing features of Tesla's new Model X electric vehicle is the wing-like door system (like the picture). Unfortunately, this model is not ready to be sold yet.
