The combustion of the substance of the candle, whether it be stearin or wax, occurs in the outer part of the flame. Outside, the flame is washed by air, supplying it with oxygen. From the inside, less hot gaseous fuel, evaporated from the wick, continuously flows into the outer part of the flame. To make sure that the outer part of the flame is the hottest, insert for a very short time, for a moment, into the flame, closer to the wick, where a rather dim glow is clearly visible, a piece of paper. With a quick movement of the hand, the piece of paper will not have time to catch fire, but a dark ring will be imprinted on it. It was formed by the bright, outer, hottest part of the flame. She charred the paper in the form of a dark ring.

Experiments with the outer part of the flame

Let's do the second experiment with a match. Take a thick match and insert it, too, for a moment into the same part of the flame as in the previous experiment. The match should be held horizontally, by its head, so that it does not flare up. Two charred spots will appear on the match. These are the places that the outer part of the flame has touched.

In the middle, between the charred marks, the match remained uncharred.

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. ... >>

By 2025, HDD capacity will grow to 100 TB 25.11.2014

The Advanced Storage Technology Consortium (ASTC) predicts a massive market launch of Hear-Assisted Magnetic Recording (HAMR) technology in 2017. This will increase the annual increase in the density of recording information on the HDD up to 30%.

In addition, ASTC claims that Bit Patterned Magnetic Recording technology will be introduced in 2021. In conjunction with HAMR technology, these innovations will achieve information recording density of up to 10 Tbit per square inch by 2025. This, in turn, will lead to the first 3,5-inch hard drives with capacities up to 100 TB.

Seagate Technology has already demonstrated its first drives using thermal magnetic recording technology. But such HDDs will enter mass production only in 2016. And in 2015, ASTC expects hard drives up to 10TB to hit the market using SMR technology.

Recall that the principle of operation of devices using HAMR technology is local laser heating and magnetization reversal in the process of recording the surface of hard disk platters. Heating the surface can significantly reduce the size of the magnetic region that stores one bit of information.

It is also interesting to note the recent achievement of TDK, which promised to release HAMR drives with a capacity of up to 2015 TB and possibly even higher in late 2016 or early 15.
