For cutting glass tubes you can use the following technique: wrap the place of the tube where you want to cut it with a fairly wide strip of paper of such length that it wraps the tube several times, and glue the ends, and you should pay attention to the fact that the edge of the paper exactly matches the place of the intended cut .

Next to this piece of paper, in exactly the same way, a second strip of paper is glued so that between them a very narrow space of uncovered glass of uniform width around the circumference is obtained, along which the cut must pass. It is useful to moisten the strips a little before wrapping. Then a narrow space is placed between the papers above the fire (cylinder of a kerosene lamp or alcohol burner). The tube is rotated over the flame until the space of unprotected glass between the pieces of paper is warm enough so that a drop of cold water placed on the spot causes a clean and even cut.

The papers wrapping the glass tube prevent the penetration of heat to the surfaces covered by them, and therefore the flame acts especially intensely on the unprotected strip of glass. Before aiming the flame at the glass tube, it is necessary to dry the pieces of paper wrapped around the tube well, because dampness on the glass can cause it to break in the wrong line.

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. ... >>

Salt marsh microbes for hydrogen energy 31.07.2013

In the highly saline waters of saline lakes, special microorganisms, halobacteria, live, which give the lakes a specific pink color. As it turned out, the protein contained in the membranes of halobacteria can revolutionize the production of hydrogen fuel.

Scientists at the US Department of Energy's Argonne National Laboratory have come up with a new way to use sunlight to create clean hydrogen fuel. The study's lead author is Elena Rozhkova, a nanotechnology specialist who works for the US Department of Energy. The main goal of this work is to send oil to the back of history as the main source of fuel for modern transport.

It is possible that halobacteria can help in the production of cheap hydrogen fuel, at least experiments indicate such a possibility. Elena Rozhkova and her colleagues were able to combine the bacterial pigment bacteriorhodopsin with semiconductor nanoparticles of titanium dioxide and platinum. The result is a complex that can act as a catalyst in the production of hydrogen.

Scientists have previously been aware of the great potential of titanium dioxide nanoparticles in alternative energy. So, back in 1970, Japanese scientists discovered that a titanium dioxide electrode in bright ultraviolet light is able to separate water molecules and thus produce hydrogen. This phenomenon is known as the Honda-Fujishima effect. Since then, scientists have made great efforts to commercialize this technology, but, unfortunately, titanium dioxide only reacts with ultraviolet light, as a result of which most of the sunlight is not used to produce hydrogen.

Scientists decided to fill this gap with the help of bacteriorhodopsin, which can act as a proton pump and, together with nanoparticles, creates a hybrid circuit that effectively uses maximum sunlight to produce hydrogen.
The proton pump is based on proteins that naturally vibrate the cell membrane and transfer protons from inside the cell to the extracellular space. In the new setup, protons supplied by bacteriorhodopsin interact with free electrons on small patches of platinum located in a titanium dioxide matrix. When this structure is taught by sunlight, hydrogen molecules are formed on platinum nanoparticles.

The new "biohybrid" photocatalyst outperforms most other similar hydrogen production systems and could become a commercially viable source of clean fuel. At the same time, all the raw materials that will be needed to produce hydrogen are salty sea water and sunlight. Later, the burnt hydrogen will again turn into water, fall out as rain or snow, and the cycle of the raw material/fuel cycle will repeat.
