giant crystals

12.10.2000

Researchers from the Lawrence Laboratory in Livermore (USA) managed to grow huge crystals of potassium pyrophosphate.

The largest of the crystals has a volume of a quarter of a cubic meter and weighs 318 kilograms. It grew in a large tank, where a solution of potassium pyrophosphate evaporated at a temperature of 65 degrees Celsius. Molecules were deposited on a seed smaller than a thimble, and after 52 days a transparent giant grew with almost no defects in the crystal lattice.

The crystals will be used to build super-powerful lasers that are used in controlled nuclear fusion experiments.

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 ... >>

Eye-Fi Mobi cards for wireless image transfer 06.06.2013

The range of Eye-Fi, which produces SD memory cards combined with wireless adapters, has been replenished with two models of the new Eye-Fi Mobi series.

According to the manufacturer, Eye-Fi Mobi is the first memory card specifically designed to link a camera and a mobile device. Pictures taken by the camera in which such a card is installed are instantly visible on a tablet or smartphone with iOS or Android connected via a wireless channel.

Mobi claims to eliminate the hassle of transferring footage, allowing the photographer to focus on the shoot. Pictures transferred to a mobile device can be viewed, edited, shared on social networks and sent by mail as if they were taken with the built-in camera of a smartphone or tablet. There is no need to put up with the limitations of the built-in camera.

Among the advantages of Eye-Fi Mobi, the manufacturer notes the ease of installation and use. It does not require a computer or other equipment to operate. It is enough to install the appropriate application on your mobile device and enter the 10-digit card ID. One and the same card can be linked to several mobile devices. Although Wi-Fi is used for communication, no router or access point is needed.

The novelty is offered in two versions of volume: 8 and 16 GB. The cards cost $50 and $80 respectively. Both are labeled Class 10.
