U-shaped computer keyboard

25.06.2003

The American company SafeType has released an original ergonomic keyboard, which is designed to save computer users from the inconvenience of traditional text input devices.

The new keyboard has a U-shape. On the two side panels are alphanumeric and function keys. In this case, the keys that on a conventional keyboard fall under the left hand are on the left panel, and under the right hand - on the right. On the horizontal part of the keyboard there are control keys, multimedia keys, cursor control and an additional numeric keypad.

Such an unusual keyboard configuration is due to the fact that with the vertical arrangement of the keys, the forearms are in the so-called neutral position (thumbs pointing up), in which the wrists practically do not strain. This is especially noticeable when working for a long time. However, such a keyboard also has serious drawbacks. To work with it, you need to know the method of touch typing, since looking at the keyboard is very uncomfortable.

The last two rows of keys are practically impossible to see without turning your head. Therefore, the keyboard is equipped with two mirrors that reflect these keys, and the inscriptions on the keys themselves are written in a mirror version.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

Recycling plastic into graphene with the release of pure hydrogen 13.09.2023

The problem of environmental pollution from plastic waste continues to require new solutions, motivating scientists around the world to look for innovative ways to combat this environmental threat. However, what if plastic could be made into a valuable resource rather than just waste? This question remains open, but scientists from Rice University in the US are proposing a unique solution that could change the plastic industry and make it more environmentally sustainable.

A team of scientists from Rice University's Department of Materials Science and Nanoengineering has developed a technology to convert waste plastic into valuable graphene, releasing pure hydrogen in the process. Hydrogen is considered one of the potential fuels of the future, since its combustion can provide high levels of energy and only produce ordinary water as a byproduct. This makes hydrogen cleaner than refined petroleum and more convenient as a vehicle fuel than electric batteries, which require a long charge.

It should be noted that hydrogen is already used in industry, but current methods of its production are associated with carbon dioxide emissions, and for every ton of hydrogen, 10 to 12 tons of carbon dioxide are produced.

The new method developed by the scientists involves a technology known as "pulsed Joule heating". By passing a short electrical pulse through the plastic, which instantly heats up to 2,5 thousand degrees Celsius due to the resistance of the current, carbon atoms are bonded into the graphene structure, and hydrogen atoms are released as a pure gas.

Despite the need to further reduce the cost of production, this method has the potential to change the game, allowing for more efficient recycling of plastic waste, the production of green hydrogen and the creation of graphene, which on the market costs between $60 and $200 per ton.

Kevin Vis, one of the authors and a chemist, said: "Our method reduces CO2 and greenhouse gas emissions from hydrogen production by 84% compared to existing industrial steam methane reforming methods." This approach could be the key to a cleaner, more sustainable future energy and plastic waste management.
