Nanotube cooler


American scientists have used carbon nanotubes to cool microcircuits.

Veterans of computerization remember that the 386th processor worked without any fan, the 486th needed a heatsink with a fan, the heatsink for the first Pentiums was already recommended to be put on thermal paste, and now neither the central processor nor the video card works without it. And there is no end in sight. So, heating engineers need to look for new answers to the question: how to remove the maximum heat in the shortest time?

Another idea came from materials scientists from Purdue University (USA). The new material is carbon nanotube parquet, which is applied directly to the silicon substrate of the microcircuit, as well as to the surface of the heat sink using plasma evaporation and condensation.

"The nanotubes that cover both bonding surfaces are firmly intertwined. We are not talking about a mechanical connection - however, heat passes excellently, ten times faster than without nanotubes. Moreover, if the nanotube coating is impregnated with thermal paste, the heat removal rate will become even faster ", - says the head of the work, Associate Professor Timothy Fisher.

Blinking of the magician and his audience 19.05.2024

Magic and illusions have always captured the attention of the public, but what happens behind the scenes of the magician and in the brains of his audience? Scientists from the UK decided to solve this mystery by conducting a new study involving ten illusionists of varying experience. Illusionists, some of whom had been practicing magic for more than half a century, others for only six months, were invited to demonstrate the same trick - the popular coin trick. Recordings of their performances during training and on stage showed that each of them began to blink significantly more often at the moment of performing the trick. The study's findings indicate that magicians' blink rate may be related to unconscious aspects of their performance. At the same time, as scientists have found, spectators also begin to blink more often, following the movements of the illusionist. This observation supports the idea that magicians may be catalysts for blinking in audiences. Additional research has shown that magicians blink more often during ... >>

Ultrasonic coffee machine 19.05.2024

Iced coffee has become an integral part of coffee culture in recent years. Therefore, engineers from the University of New South Wales decided to improve its preparation. They have developed an ultrasonic coffee machine that reduces the cold brew time for ground coffee beans from 12-24 hours to significantly less time. Iced coffee, or "Cold brew", is popular due to its smoothness, low acidity and low bitterness. It is prepared by steeping ground coffee in cold water for a long time. Unlike traditional hot brewing, which often imparts bitterness to coffee, cold brewing extracts more delicate and complex flavors from the coffee beans. The innovative system, presented by a team of engineers, introduces ultrasonic technology into the coffee preparation process. The system uses ultrasonic waves to speed up the process of extracting oils, flavor and aroma from ground coffee. This allows you to significantly reduce the time ... >>

The speech of sperm whales is similar to that of humans 18.05.2024

In the world of the ocean, where the mysterious and unknown coexists with the studied, sperm whales, with their huge brains, are of particular interest to science. Researchers, working with a huge array of audio recordings collected during the Dominica Sperm Whale Project (DSWP) - more than 8000 recordings, seek to unravel the secrets of their communication and understand the structure and complexity of the language of these mysterious creatures. By studying in detail the recordings of 60 sperm whales in the eastern Caribbean, scientists have revealed surprising features of their communication, revealing the complexity of their language. "Our observations indicate that these whales have a highly developed combinatorial communication system, including rubato and ornaments, which indicates their ability to quickly adapt and vary during communication. Despite significant differences in evolution, sperm whales have elements in their communication that are characteristic of human communication," says Shane Gero, a biologist at Carleton University and director of the CETI project. Issl ... >>

Electron spin for quantum information transfer 18.05.2024

The transfer of quantum information remains one of the key tasks of modern science. Recent advances in the use of electron spin to expand the capabilities of information transfer in quantum systems have become very important. Researchers at Lawrence Berkeley National Laboratory are pushing the frontiers of quantum information science by experimenting with the possibilities of electron spin. Electron spin, a natural quantum bit, is a potentially powerful means for storing and transmitting information in quantum systems. Magnon wave packets, collective excitations of electron spin, have revealed their potential to transmit quantum information over significant distances. The work of Berkeley Lab researchers has revolutionized the way such excitations propagate in antiferromagnets, opening up new prospects for quantum technologies. Using pairs of laser pulses, scientists disrupted antiferromagnetic order in one place and simultaneously studied it in another, creating ... >>

Sound-absorbing silk 17.05.2024

In a world where noise is becoming increasingly intrusive, the emergence of innovative materials that can reduce its impact is of great interest. MIT researchers have unveiled a new sound-absorbing silk fabric that promises to revolutionize quiet spaces. The Massachusetts Institute of Technology (MIT) has made significant breakthroughs in the field of sound absorption. Researchers have developed a special silk fabric that can effectively absorb sound and create cozy, quiet environments. The fabric, thinner than a human hair, contains a unique vibrating fiber that is activated when voltage is applied to it. This feature allows the fabric to be used to suppress sound waves in two different ways. The first method uses fabric vibrations to generate sound waves that cover and cancel out unwanted noise, similar to noise-canceling headphones. This p ... >>

Xiaomi Mi Powerbank Pro portable battery with USB Type-C port 14.03.2016

Xiaomi has announced the Mi Powerbank Pro pocket battery, designed to charge mobile devices away from the mains.

The novelty uses a battery capacity of 10 mAh. It is claimed that a full charge will be enough to replenish the iPhone 000's energy reserve four times. iPad mini can be fully charged once and half charged once.

One of the features of the novelty is the presence of a symmetrical USB Type-C port. This allows you to power the next generation of mobile devices, such as the 12-inch Apple MacBook and the second generation Google Chromebook Pixel.

Another feature of Mi Powerbank Pro is the fast charging function. It takes no more than three and a half hours to fully replenish the energy reserve.

The portable battery measures 128,5 x 75 x 12,6 mm and weighs approximately 220 grams. The housing has an LED status indicator. It will be possible to buy a novelty at an estimated price of 20-25 US dollars.
