An international team of physicists led by the Helmholtz Center Dresden-Rossendorf, the University of Rostock and the French Polytechnic School have obtained nanodiamonds from plastic bottles using laser flashes. The work was published in the journal Science Advances.
During the experiment, scientists fired intense laser flashes at a thin sheet of PET plastic used to make beverage bottles. Powerful pulses heated it up to 6,000 degrees Celsius and created a shock wave that, in a few nanoseconds, compressed the substance to a pressure millions of times higher than atmospheric pressure. The scientists found that this produced diamonds several nanometers in size.
A similar process occurs on the ice giants of the solar system – Uranus and Neptune. The experiment of scientists made it possible to confirm that diamond rain really falls on them. PET was chosen because it has the perfect balance of carbon, hydrogen, and oxygen to mimic conditions on icy planets. The presence of oxygen in the plastic composition facilitated the splitting of bonds between hydrogen and carbon. This allowed carbon atoms to combine more intensely, forming diamonds. The team conducted their experiments at the SLAC National Accelerator Laboratory in California, home to one of the world’s most powerful Linac X-ray lasers (LCLS).
Scientists suggest that the so-called superionic water could form as a result of the experiment. Its structure consists of oxygen atoms united in a crystal lattice in which hydrogen nuclei move freely. They plan to repeat the experiment at the XFEL facility in Hamburg, the world’s most powerful X-ray laser.
The scientists’ technique can form the basis of a new method for the production of nanodiamonds, which are necessary, for example, for highly sensitive quantum sensors, contrast agents for medicine, and catalysts for the splitting of carbon dioxide.
The “aged” Toyota RAV4 has become more modern. A new version of the Mitsuoka Buddy crossover is presented
The Japanese company Mitsuoka has introduced an updated retro crossover Buddy, which is an “aged” version of the popular Toyota RAV4 in the style of old American SUVs from the 70s.
According to Drom.ru, the changes include enlarged screens of the digital instrument panel and multimedia complex (the exact diagonals are not reported), as well as a full-time DVR, which will be installed from the factory.
Mitsuoka Buddy is offered in two versions to choose from. Buyers are available a pure gasoline version with a 2.0-liter engine and a hybrid with a 2.5-liter gasoline engine and an electric motor.
Production of the “aged” Toyota RAV4 began in June last year. The car differs from the Toyota crossover in its original body design. The front fenders, hood and bumper are made in the style of the Chevrolet K5 Blazer of the 1970-1980s. The headlights from the RAV4 were replaced with universal “rectangles”, the radiator grille is made in the form of a nickel-plated “grill”, and the original bumper with a chrome trim and vertical lights from Cadillac integrated through the adapter is installed at the back.
The original Buddy body panels are made from polypropylene and molded ABS plastic.
Gordon Freeman has become the hero of a new game in the Half-Life universe: it will appear soon on Steam
Developer PinkyDev has revealed that the game, codenamed Codename: Loop, which is a spin-off of the Half-Life shooter, has received permission from Valve to be placed on Steam in the near future.
The main protagonist of Codename: Loop is the protagonist of the Half-Life series, Gordon Freeman. The project will combine an isometric shooter and roguelike elements. The project is expected to be released this year.
An important point of Codename: Loop is its compatibility with the original Half-Life BSP file format. This allows Codename: Loop to take advantage of the GoldSrc engine while maintaining the look and feel of Half-Life in the Unity engine. Codename: Loop also features third-person views and a classic first-person view for fans who want to create FPS-style levels. BSP compatibility enhances the potential of Codename: Loop to support the modding community, as level designers can use existing tools to create maps and campaigns in Codename: Loop.
Keeping the classic spirit of Half-Life alive is a top priority for PinkyDev, who wrote in the project’s latest update: “I will do my best to support the Steam Workshop so everyone can share campaigns and levels and support this game forever.”
Tesla Semi production has finally begun – almost 5 years after the announcement. Pepsi will receive electric trucks on December 1, 2022
According to CEO Elon Musk’s announcement, Tesla has begun production of its Semi electric truck and plans to begin shipping it to Pepsi as early as December 1, 2022.
The soft drink company ordered 100 electric vehicles in December 2017, just a month after Tesla first unveiled its new creation to the world.
Tesla promises that the Semi can accelerate from 0 to 96 km/h mph in 20 seconds even when “fully loaded” and maintain “the same speed as on the highway, even on steep climbs.” It also promises that you can charge your battery up to 70% in just 30 minutes. The power reserve, depending on the version, will be from 480 to 800 km. In Musk’s own words, “driving a car is a lot of fun.”
Until 2022, there was little news about the car. In May, Tesla began accepting orders and taking a $20,000 deposit, and in August, Musk said deliveries of the 500-mile-range version of the truck would begin this year.
Tesla has pushed back the release dates of its vehicles many times. The Cybertruck pickup has been delayed several times, with Musk saying deliveries will now begin in 2023. The second-generation Tesla roadster that was announced alongside the Semi was originally expected in 2020 but has yet to be released.
