Energy from space for Starship 08.05.2024

Producing solar energy in space is becoming more feasible with the advent of new technologies and the development of space programs. The head of the startup Virtus Solis shared his vision of using SpaceX's Starship to create orbital power plants capable of powering the Earth. Startup Virtus Solis has unveiled an ambitious project to create orbital power plants using SpaceX's Starship. This idea could significantly change the field of solar energy production, making it more accessible and cheaper. The core of the startup's plan is to reduce the cost of launching satellites into space using Starship. This technological breakthrough is expected to make solar energy production in space more competitive with traditional energy sources. Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

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, ... >>

Major risk factor for gambling addiction 07.05.2024

Computer games are becoming an increasingly popular form of entertainment among teenagers, but the associated risk of gaming addiction remains a significant problem. American scientists conducted a study to determine the main factors contributing to this addiction and offer recommendations for its prevention. Over the course of six years, 385 teenagers were followed to find out what factors may predispose them to gambling addiction. The results showed that 90% of study participants were not at risk of addiction, while 10% became gambling addicts. It turned out that the key factor in the onset of gambling addiction is a low level of prosocial behavior. Teenagers with a low level of prosocial behavior do not show interest in the help and support of others, which can lead to a loss of contact with the real world and a deepening dependence on virtual reality offered by computer games. Based on these results, scientists ... >>

Traffic noise delays the growth of chicks 06.05.2024

The sounds that surround us in modern cities are becoming increasingly piercing. However, few people think about how this noise affects the animal world, especially such delicate creatures as chicks that have not yet hatched from their eggs. Recent research is shedding light on this issue, indicating serious consequences for their development and survival. Scientists have found that exposure of zebra diamondback chicks to traffic noise can cause serious disruption to their development. Experiments have shown that noise pollution can significantly delay their hatching, and those chicks that do emerge face a number of health-promoting problems. The researchers also found that the negative effects of noise pollution extend into the adult birds. Reduced chances of reproduction and decreased fertility indicate the long-term effects that traffic noise has on wildlife. The study results highlight the need ... >>

ultrasonic magic wand 12.01.2015

"Wingardium Leviosa" - such a spell was used by characters from the fairy tale series about Harry Potter to make objects fly through the air with a wave of a magic wand. But while writers and directors come up with new fantastic stories, science, step by step, brings to life things that seemed impossible before. This time it was about moving objects through the air, or levitation. Levitation can be called such a physical effect in which an object without visible support is or moves in the air. For example, if an ordinary magnet is placed over a superconducting material that was previously cooled to a low temperature, then a "miracle" will happen - the magnet will float freely in the air at a low altitude. This is due to the special behavior of the magnetic field in superconductors.

Such a phenomenon, although very curious, is of little use for practical use: the need to move magnets over a superconductor cooled to the temperature of liquid nitrogen will not arise for everyone. It is a completely different matter if a method is invented to move any objects contactlessly, regardless of their nature. Such an invention will be widely demanded in those areas where the extreme purity of materials is important. For example, in pharmaceuticals or microelectronics: there any extra contact with the material can bring unwanted impurities into it. Physicists from the University of Sao Paulo in Brazil have proposed a way to make small objects not only float in the air, but also move them in the right direction.

To overcome the force of gravity, the researchers used the pressure exerted by sound waves. You can feel the power of sound if you stand in front of a powerful speaker operating at full volume. Sound is a vibration that occurs in any medium. It can be air, water or solid materials. There are no sound waves in space, because there is no medium in which they can propagate: vacuum is a silent void. From a physical point of view, the transmission of sound in air is the movement of areas of high and low pressure. Pressure fluctuations create a force that can act on mechanical objects. This is how our ear is arranged, where the sounds of the world around us are transmitted to the brain through vibrations of the eardrum.

Now we need to remember one more feature of oscillations - the existence of standing waves. The simplest example: if you fix one end of a long rope, and move the other up and down at a constant frequency, then some points of the rope will remain motionless. The formation of such a standing wave occurs due to the superposition of two waves - the original, created by the movement of the free end of the rope, and the reflected wave. The effects that arise when sound waves are superimposed on each other formed the basis of the developed method of ultrasonic levitation. The emitter emits ultrasonic waves that are reflected from a surface located at some distance. The radiated and reflected waves add up, forming something like a corridor, in which areas of high and low pressure alternate. If an object falls into the area of ​​a standing ultrasonic wave, the energy of the waves is enough to compensate for the force of gravity, and we observe the effect of levitation.

Despite the fact that the method of ultrasonic levitation began to develop a few years ago, it was not easy to achieve a stable hold of objects in the air. For a long time it was not possible to create a stable standing ultrasonic wave of sufficient power: a slight movement of the emitter or reflector - and the effect disappeared. To solve this problem, Marco Andrade and his colleagues used the principle of standing wave formation based on multiple reflections. They made a special concave ultrasonic reflector with which they managed to achieve levitation of small plastic balls without fine-tuning the system. Even if you hold the wave reflector in your hand, the levitation effect does not disappear - until recently it seemed impossible. This technology has much more chances for real application.
