paper transistors

11.02.2009

Portuguese engineers at the New University of Lisbon have developed a way to print transistors on paper.

The paper, coated with a thin layer of zinc oxide with additions of gallium and indium, serves as both a semiconductor and an insulator between the two parts of the transistor printed on opposite sides of the sheet. In terms of characteristics, paper transistors are close to ordinary silicon ones, but they are much cheaper and can be bent without harm.

It is assumed that electronic circuits with such transistors can be printed, for example, on banknotes in order to facilitate their recognition in vending machines and make counterfeiting more difficult.

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 ... >>

The secret to a good sense of rhythm in musicians 14.09.2020

The ability to hit the beat turned out to be associated with the speed and degree of synchronization of the given rhythm and the rhythm of brain activity.

Researchers at McGill University in Toronto have studied how the synchronization of the brain waves of musicians with the rhythm of the audio recordings they listened to is related to the ability of the same musicians to reproduce a given tempo without error. The results of the work showed that this is what distinguishes a solid master from one who can "miss" past the beat. The ability to simultaneously listen and perform synchronized movements, such as in dance or when playing an instrument under a metronome, contains three levels of activity: listening, synchronization, reproduction.

In the experiment, 29 experienced musicians aged 18 to 30 listened to and reproduced different rhythmic patterns by tapping their fingers on the table. At this time, scientists measured their brain activity using an electroencephalogram. The first rhythm was a simple repetition of evenly spaced identical notes. The second, medium in complexity, was an alternation of high and low notes. The third rhythm, the most intricate, was the superimposition of four low notes on three high notes: the notes were evenly distributed in one measure.

It turned out that those participants whose brainwaves synchronized more accurately and faster with the rhythm track were better at identifying versions of rhythms with previously skipped notes. Also, these musicians more accurately reproduced the rhythm they heard: both at the same time as listening to the track, and from memory. The authors of the study emphasized that the degree of synchronization of brain waves with musical rhythm is a feature that can be trained, and the sense of rhythm can be “improved” by regularly practicing listening and reproducing rhythmic patterns.
