paper that stores electricity

15.12.2015

In Sweden, created "paper" that stores the energy of electricity. Researchers working at Linköping University have developed a material with an outstanding ability to store electricity. Scientists themselves call it "energy paper".

The material consists of cellulose nanofibers and a conductive polymer. A sheet of such "paper" with a diameter of 15 cm and a thickness of less than 1 mm has a capacitance of 1 F. This is comparable to the capacitance of supercapacitors available on the market today. The sheet can withstand hundreds of recharge cycles and recharges in seconds. The new material demonstrates record values for organic electronics in four parameters, including capacitance and current strength.

One of the most promising areas of application of a material capable of storing energy, scientists consider power supply systems using renewable sources - for example, wind generators or solar panels. The fact is that such systems are characterized by fluctuations in the amount of generated energy, and the presence of a capacity for its storage allows for uniform power supply to the load, regardless of weather conditions, time of day or year.

The advantages of the material, its creators include the ability to produce sheets of arbitrary thickness, as well as the fact that a sheet of "energy paper" can be folded like a sheet of ordinary paper.

Machine for thinning flowers in gardens 02.05.2024

In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers. ... >>

Advanced Infrared Microscope 02.05.2024

Microscopes play an important role in scientific research, allowing scientists to delve into structures and processes invisible to the eye. However, various microscopy methods have their limitations, and among them was the limitation of resolution when using the infrared range. But the latest achievements of Japanese researchers from the University of Tokyo open up new prospects for studying the microworld. Scientists from the University of Tokyo have unveiled a new microscope that will revolutionize the capabilities of infrared microscopy. This advanced instrument allows you to see the internal structures of living bacteria with amazing clarity on the nanometer scale. Typically, mid-infrared microscopes are limited by low resolution, but the latest development from Japanese researchers overcomes these limitations. According to scientists, the developed microscope allows creating images with a resolution of up to 120 nanometers, which is 30 times higher than the resolution of traditional microscopes. ... >>

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

The threat of space debris to the Earth's magnetic field 01.05.2024

More and more often we hear about an increase in the amount of space debris surrounding our planet. However, it is not only active satellites and spacecraft that contribute to this problem, but also debris from old missions. The growing number of satellites launched by companies like SpaceX creates not only opportunities for the development of the Internet, but also serious threats to space security. Experts are now turning their attention to the potential implications for the Earth's magnetic field. Dr. Jonathan McDowell of the Harvard-Smithsonian Center for Astrophysics emphasizes that companies are rapidly deploying satellite constellations, and the number of satellites could grow to 100 in the next decade. The rapid development of these cosmic armadas of satellites can lead to contamination of the Earth's plasma environment with dangerous debris and a threat to the stability of the magnetosphere. Metal debris from used rockets can disrupt the ionosphere and magnetosphere. Both of these systems play a key role in protecting the atmosphere and maintaining ... >>

Solidification of bulk substances 30.04.2024

There are quite a few mysteries in the world of science, and one of them is the strange behavior of bulk materials. They may behave like a solid but suddenly turn into a flowing liquid. This phenomenon has attracted the attention of many researchers, and we may finally be getting closer to solving this mystery. Imagine sand in an hourglass. It usually flows freely, but in some cases its particles begin to get stuck, turning from a liquid to a solid. This transition has important implications for many areas, from drug production to construction. Researchers from the USA have attempted to describe this phenomenon and come closer to understanding it. In the study, the scientists conducted simulations in the laboratory using data from bags of polystyrene beads. They found that the vibrations within these sets had specific frequencies, meaning that only certain types of vibrations could travel through the material. Received ... >>

Performed quantum teleportation 02.01.2020

Scientists from the UK and Denmark have conducted the world's first quantum teleportation - they were able to transfer the quantum state of a particle between two chips. This should be the cornerstone for quantum communication technologies. The accuracy of data transmission was 91%.

Scientists from the University of Bristol in the UK and the Technical University of Denmark have created chip-like devices that can generate and manipulate individual light particles in programmable nanoscale circuits, thus implementing the laws of quantum physics.

These chips are able to encode quantum information in the light that is generated inside the circuit and can process this information with high efficiency and extremely low noise. The invention should help humanity move on to creating more complex circuits for quantum computing and communications than those that exist today.

Initially, the photons in each chip were in the same quantum state. Each chip was then programmed to perform a series of entanglement manipulations. In the main experiment, two microcircuits were involved. Between them, it was possible to transfer the individual quantum state of the particle after quantum measurements. During the measurements, a phenomenon of quantum physics was used, in which the entangled bond is simultaneously destroyed, and the state of the particle is transferred to another particle already in the receiver chip.

As a result, an even more complex scheme was created, containing four single-photon sources. All sources have been tested and found to be virtually identical, i.e., emitting almost the same photons, which is extremely important for entanglement exchange.

The researchers were able to demonstrate some other important functionality of their chips. These include entanglement permutation (required for quantum repeaters and quantum networks) and four-photon gigahertz states (required in quantum computing and the quantum internet).
