Supercapacitors made from cigarette butts

18.08.2014

Scientists from South Korea have found a way to turn cigarette butts into supercapacitors. The resulting energy storage can be used to power a variety of devices.

According to one of the authors of the study, Jeong Hep Yi, used cigarette filters can be converted into high-efficiency carbon material through a simple one-step process, which, among other things, is an environmentally friendly solution to the problem of significant energy demand.

The supercapacitor, which the scientists ended up with, can store a significant amount of energy. At the same time, it is able to charge quickly and it holds a charge longer than many alternative designs.

It is worth noting that cigarette butts are a very common type of garbage all over the world. Every year more than 765 thousand tons of cigarette butts are thrown away in the world. Thanks to the development of Korean scientists, this garbage can now be used rationally.

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 ... >>

Embryo from stem cells 10.09.2023

Scientists from the University of Cambridge and the California Institute of Technology have made significant progress in growing artificial "near-embryos" from stem cells. The experiment provides new opportunities for research into genetic disorders, but also raises serious questions about morality and legality by creating structures that closely resemble the human embryo.

The embryo created had absolutely no relation to eggs or sperm and was devoid of a heart or brain development. However, it contained cells that form the placenta, the yolk sac, and the embryo itself.

This progress has been achieved by reprogramming embryonic stem cells. Despite this, the use of synthetic embryos for clinical purposes is not possible in the near future. This would be a flagrant violation of the law and it remains unclear whether such structures can develop further after the early stages of formation.

The researchers hope that these models will be useful in understanding the "black box" of human development, that is, the period after 14 days from the moment of fertilization, which is legally established as the deadline for culturing and studying embryos in the laboratory.

Robin Lovell-Bedge, head of the department of stem cell biology and developmental genetics at the Francis Crick Institute in London, explained: "The idea is that by creating normal human embryonic development using stem cells, we can gain a lot of information about the early stages of development and identify potential harm by avoiding the use of early embryos for research."

Previously, the same team of scientists demonstrated how mouse stem cells are able to develop into early embryo-like structures. These structures included the intestines, early forms of the brain, and even the beating heart. Currently, researchers are actively working on creating similar human models.
