Frost-resistant lithium-ion battery

15.03.2024

An international team of scientists led by Zhejiang University professor Fan Xiulin has developed a new type of electrolyte that allows lithium-ion batteries to function at extremely low temperatures. This new breakthrough opens the door to using batteries even at -80°C.

Research into a new electrolyte for lithium-ion batteries represents a significant step forward in the development of energy-dense and cold-resistant batteries. This breakthrough could have far-reaching implications for various industries that require power supply in extreme temperature environments.

Xiulin emphasizes that such batteries can be used in various fields, including telecommunications, transportation, Arctic research, aviation and others.

Scientists have created an innovative electrolyte that consists of rare solvent molecules that allow them to achieve characteristics previously unavailable for modern electrolytes.

This electrolyte enables fast charging in cold conditions, allowing lithium-ion batteries to operate with high capacity and stability even at -80°C. Also, in extremely low temperatures, the battery can be charged to 80% of its capacity in just 10 minutes.

The scientists note that their electrolyte design is effective not only for lithium-ion batteries, but also for sodium-ion and potassium batteries. However, more research and experimentation is required for this technology to be used more widely.

Recently, scientists from Harvard University introduced a low-cost sodium-ion battery using waste tea leaves. This is another example of innovation in the development of energy-dense batteries.

Artificial leather for touch emulation 15.04.2024

In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>

Petgugu Global cat litter 15.04.2024

Taking care of pets can often be a challenge, especially when it comes to keeping your home clean. A new interesting solution from the Petgugu Global startup has been presented, which will make life easier for cat owners and help them keep their home perfectly clean and tidy. Startup Petgugu Global has unveiled a unique cat toilet that can automatically flush feces, keeping your home clean and fresh. This innovative device is equipped with various smart sensors that monitor your pet's toilet activity and activate to automatically clean after use. The device connects to the sewer system and ensures efficient waste removal without the need for intervention from the owner. Additionally, the toilet has a large flushable storage capacity, making it ideal for multi-cat households. The Petgugu cat litter bowl is designed for use with water-soluble litters and offers a range of additional ... >>

The attractiveness of caring men 14.04.2024

The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>

Electronic helmet for truck drivers 14.04.2024

Road safety, especially for drivers of heavy construction equipment, is a top priority for engineers and scientists. In light of this, the German Fraunhofer Institute for Structural Strength and System Reliability has introduced a new product - an electronic helmet, which is designed to protect drivers from serious injury when driving construction vehicles. A new electronic helmet developed by a team of engineers from the Fraunhofer Institute opens up new perspectives for the safety of truck and construction equipment drivers. The device is capable of monitoring the level of shaking in the car cabin and warning the driver of possible danger. The basis of the helmet's operation is a built-in piezoelectric sensor, which generates electricity during physical deformation. This mechanism allows the device to respond to intense vibrations typical of construction equipment. When the level of deformation exceeds safe values, an alarm system is activated on the helmet, ... >>

Antivitamins instead of antibiotics 13.04.2024

The problem of bacterial resistance to antibiotics is becoming increasingly serious, posing a threat to the effective treatment of infections. In light of this, researchers are looking for new ways to combat superbugs. One of the promising directions is the use of antivitamins that can have an antibacterial effect. Antivitamins, although known as the opposite of vitamins, have proven to be a promising tool in the fight against bacterial antibiotic resistance. A study conducted by scientists from the University of Göttingen in Germany confirmed their potential in creating new drugs to combat dangerous infections. With the rise of antibiotic-resistant superbugs, there is a need to find alternative treatments. Antivitamins are molecules similar to vitamins, but capable of inhibiting bacterial activity without harm to the human body. At the moment, science knows only three antivitamins: rose ... >>

Router ASUS RT-AC87U 02.04.2015

ASUS has launched the RT-AC87U dual-band wireless router with a 4x4 antenna configuration (reception x transmission). Thanks to the support of modern technologies, this model provides high data transfer speed and extended wireless network coverage, so the device is suitable for home networks with many client devices.

The ASUS RT-AC87U is an 802.11ac wireless router with a 5Mbps 1734GHz bandwidth that exceeds a wired Gigabit Ethernet connection. In addition, thanks to Broadcom TurboQAM technology, the bandwidth of the 802.11n interface in the 2,4 GHz band when working with compatible network equipment (for example, the ASUS PCE-AC68 adapter) is up to 600 Mbps. Thus, the maximum total data transfer rate of this router is 2334 Mbps.

With four powerful transceivers, ASUS RT-AC87U extends wireless coverage by 33% compared to standard models with 3x3 antenna configuration. The typical coverage area of ASUS RT-AC87U is 465 square meters.

The ASUS RT-AC87U router is based on the integrated Quantenna chip, which includes a dual-core processor responsible for processing data transmitted over a Wi-Fi 802.11ac network. Another processor with a frequency of 1 GHz performs the rest of the tasks. This division of labor ensures high speed in multitasking when multiple client devices and USB drives are connected to the router at the same time.

In a test of this router with five computers (three wired and two wireless), the RT-AC87U delivered 2,4 times the total throughput (5GHz + 1,2GHz + NAT) than a typical router with one dual-core processor with a frequency of 3.0 GHz. In addition, the speed of data exchange with a USB storage device (USB 802.11) over a Wi-Fi network (XNUMXac) has almost doubled.

ASUS Ai Radar technology is responsible for improved network coverage: intelligently detecting the location of connected devices, ASUS RT-AC87U converts a weak omnidirectional signal into a strong unidirectional signal, which ensures faster data transfer.
