Sony Triporous Fiber sock material

27.10.2019

Sony's new high-tech fibers for textiles and garments promise extremely high levels of absorption of unwanted odors emitted through perspiration during active life.

Earlier this year, Sony began licensing proprietary porous organic material technology under the brand name Triporous. Now the company said that the first products based on this technology - threads, fabrics and clothes under the brand name Triporous FIBER - have begun to be delivered to the market.

Triporous is made from rice husks in a controlled combustion process. The result is a porous carbon structure that absorbs the entire spectrum of molecules from light to heavy. Triporous contains pores ranging in diameter from 2 nm to 50 nm and 1 µm. For example, ordinary activated carbon cannot absorb large molecules efficiently, while Triporous will absorb small and large molecules with equal efficiency.

Triporous FIBER fabrics and clothing, says Sony, effectively absorb the odors (molecules) of ammonia, acetic acid and isovaleric acid, substances normally released during human perspiration. Also, the new material has bactericidal properties, which prevents unpleasant odors from wet clothes. Most importantly, the Triporous FIBER material easily regains its absorbent properties after a normal wash in the washing machine. By the way, it would be great to see Triporous filters for vacuum cleaners and other cleaning household appliances that require periodic replacement of filter cartridges.

Finally, the production of Triporous FIBER is completely ecological and makes it possible to utilize organic plant residues. Up to 2 million tons of rice husks are utilized annually in Japan alone, and up to 100 million tons worldwide. This knowledge will help to warm the soul, just as the Triporous FIBER material will warm the body.

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. ... >>

MATSUSHITA Starts DVD-RAM Promotion 22.06.2003

The Matsushita Electric Industrial Corporation is about to launch one of the biggest advertising campaigns ever in the world.

The campaign will aim to promote Panasonic's new DIGA consumer DVD recorders and related DVD-RAM media format globally. One result should be the establishment of DVD-RAM as the world standard.

To implement this difficult task, they even attracted the famous film director Oliver Stone. It will deal with some aspects of the campaign, and at the same time serve as an advertisement in itself, drawing attention to the same DIGA brand.

We will be jammed with ads everywhere, with the exception of Japan and some other countries, throughout the entire time from June of this year to next May. Against this background, somewhere in late summer or early autumn, the first truly massive deliveries of these devices to literally all countries of the world will begin.
