carbon dioxide from moist air

30.01.2016

There are different technologies for capturing carbon dioxide without the help of living organisms. For example, if you pass the gases emitted by the pipes of the power plant through a solution of calcium chloride, calcium carbonate will precipitate, which can then be decomposed, returning calcium to circulation, and carbon dioxide sent for processing. Or you can try to collect carbon dioxide with a sorbent, so that then again it is isolated, sent for processing, and the sorbent is returned to business.

Until recently, there was no good sorbent: as a rule, carbon dioxide molecules stick to the same active sites as water molecules, and there is incomparably more moisture in the air than CO2. An international team of researchers has managed to create a sorbent in which moisture and carbon dioxide sit on different active sites. It was named SGU-29 after Korea's Seogang University, where the material took its final form. The basis was crystalline copper silicate.

"The sorbent is the most difficult part of the work. Now it is behind us, and carbon dioxide processing technologies are ahead. In about five years we will finish the work," says research participant Professor Osamu Terasaki from Stockholm University.

However, carbon dioxide must be extracted not only from the emissions of a factory or power plant. In the air of residential and office premises, an excess of carbon dioxide is also undesirable. It would be interesting to know whether the new sorbent can be useful here as well.

A New Way to Control and Manipulate Optical Signals 05.05.2024

The modern world of science and technology is developing rapidly, and every day new methods and technologies appear that open up new prospects for us in various fields. One such innovation is the development by German scientists of a new way to control optical signals, which could lead to significant progress in the field of photonics. Recent research has allowed German scientists to create a tunable waveplate inside a fused silica waveguide. This method, based on the use of a liquid crystal layer, allows one to effectively change the polarization of light passing through a waveguide. This technological breakthrough opens up new prospects for the development of compact and efficient photonic devices capable of processing large volumes of data. The electro-optical control of polarization provided by the new method could provide the basis for a new class of integrated photonic devices. This opens up great opportunities for ... >>

Primium Seneca keyboard 05.05.2024

Keyboards are an integral part of our daily computer work. However, one of the main problems that users face is noise, especially in the case of premium models. But with the new Seneca keyboard from Norbauer & Co, that may change. Seneca is not just a keyboard, it is the result of five years of development work to create the ideal device. Every aspect of this keyboard, from acoustic properties to mechanical characteristics, has been carefully considered and balanced. One of the key features of Seneca is its silent stabilizers, which solve the noise problem common to many keyboards. In addition, the keyboard supports various key widths, making it convenient for any user. Although Seneca is not yet available for purchase, it is scheduled for release in late summer. Norbauer & Co's Seneca represents new standards in keyboard design. Her ... >>

The world's tallest astronomical observatory opened 04.05.2024

Exploring space and its mysteries is a task that attracts the attention of astronomers from all over the world. In the fresh air of the high mountains, far from city light pollution, the stars and planets reveal their secrets with greater clarity. A new page is opening in the history of astronomy with the opening of the world's highest astronomical observatory - the Atacama Observatory of the University of Tokyo. The Atacama Observatory, located at an altitude of 5640 meters above sea level, opens up new opportunities for astronomers in the study of space. This site has become the highest location for a ground-based telescope, providing researchers with a unique tool for studying infrared waves in the Universe. Although the high altitude location provides clearer skies and less interference from the atmosphere, building an observatory on a high mountain poses enormous difficulties and challenges. However, despite the difficulties, the new observatory opens up broad research prospects for astronomers. ... >>

Controlling objects using air currents 04.05.2024

The development of robotics continues to open up new prospects for us in the field of automation and control of various objects. Recently, Finnish scientists presented an innovative approach to controlling humanoid robots using air currents. This method promises to revolutionize the way objects are manipulated and open new horizons in the field of robotics. The idea of controlling objects using air currents is not new, but until recently, implementing such concepts remained a challenge. Finnish researchers have developed an innovative method that allows robots to manipulate objects using special air jets as "air fingers". The air flow control algorithm, developed by a team of specialists, is based on a thorough study of the movement of objects in the air flow. The air jet control system, carried out using special motors, allows you to direct objects without resorting to physical ... >>

Purebred dogs get sick no more often than purebred dogs 03.05.2024

Caring for the health of our pets is an important aspect of the life of every dog owner. However, there is a common assumption that purebred dogs are more susceptible to diseases compared to mixed dogs. New research led by researchers at the Texas School of Veterinary Medicine and Biomedical Sciences brings new perspective to this question. A study conducted by the Dog Aging Project (DAP) of more than 27 companion dogs found that purebred and mixed dogs were generally equally likely to experience various diseases. Although some breeds may be more susceptible to certain diseases, the overall diagnosis rate is virtually the same between both groups. The Dog Aging Project's chief veterinarian, Dr. Keith Creevy, notes that there are several well-known diseases that are more common in certain breeds of dogs, which supports the notion that purebred dogs are more susceptible to disease. ... >>

wifi on sheep 28.12.2014

British researchers plan to equip sheep with Wi-Fi hotspots to bring high-speed Internet access to rural areas. Sheep are no strangers to wearing equipment: in the summer of 2014, they played the role of operators in the Tour de France.

A team of researchers led by Lancaster University professor Gordon Blair plans to explore the possibility of installing Wi-Fi hotspots on sheep farms in British Wales, reports The Daily Mail.

According to the researchers, this can solve the problem of providing high-speed Internet access to remote rural areas. The group received 171,5 thousand pounds sterling (about 14,5 million) for this project.

Researchers suggest that it would be possible to equip remote areas with Internet access by turning sheep grazing in wide open spaces into a chain of wireless signal transceivers.

"This could address the typically slow access speeds and poor network coverage in much of the UK's rural areas," notes The Daily Mail.

Wi-Fi modules can be integrated into digital collars - devices for monitoring the movement of sheep that farmers use.

We add that earlier sheep were already used as a kind of transport for equipment. In July 2014, these animals were equipped with cameras to film the prestigious Tour de France cycling race held in Yorkshire. The cameras on the sheep were controlled remotely.

In addition to the Internet, Blair's team will study the problems of pollution, floods and droughts. Within the framework of the project, water level sensors will be installed in the rivers on the banks and precipitation sensors. A similar system has been installed in Honduras by researchers at the Massachusetts Institute of Technology and Microsoft.

The authors of the project will try to implement one of the basic principles of the "Internet of things" - the ability of electronic devices to communicate with each other and send data to the Internet without human intervention. The researchers note that in rural areas such a concept is more difficult to organize due to the more complex landscape. However, the results are obvious - high-quality network coverage of remote areas and the availability of all kinds of sensors will help to cope with natural disasters and increase the efficiency of agriculture.
