In 1956, Nicholas McKay invented a chemical to remove lint. 65 years ago, his invention was really groundbreaking, but it had many shortcomings such as: it was expensive, could damage clothes, or if there was too much lint, the chemical was useless. . The advent of lint cutters can easily remove lint and fabric clumps. You can easily manipulate clothes, robes or a thick rug… 2. Glass cleaner The glass cleaner is a simple invention, but it is an effective assistant for housewives, saving them time compared to using a regular rag. In particular, there are now many types of smart glass cleaners such as: spraying automatic cleaner while cleaning the glass or cleaning the inner and outer glass without you needing to install a wire ladder.. 3. Working chair People who work a lot with computers often have pain in the back, neck, shoulders, nape… A special swivel chair was born to help people’s back more comfortable, it also creates support for the spine and eliminates body load on the spine. 4. Toothbrush To clean your teeth, you can’t “play” at a rate of 300 brushing strokes per minute and get into hard-to-reach places like an electric toothbrush. The brush head rotates by itself and increases movement, helping you to clean your teeth easily without much time and effort. Look for brushes that have an automatic timer for 2 minutes, which is the amount of time dentists recommend to spend brushing. 5. Sponge Sponges have many uses: clean, remove makeup and massage soft skin. Some users recommend that you massage your face with this sponge in the morning, it helps even out skin tone, then you apply cosmetics on your face, it will be smooth and easily absorbed into the skin. 6. Desk with computer cooling vents The CPU must be overloaded, resulting in the computer emitting a large amount of heat, which has a significant impact on the machine, reducing the life of the computer. So the small workbench with the vents has the effect of dissipating heat for the machine. It will be even more perfect if the heat sink is in line with the laptop’s vent.

1. Corn cob In the 1700s, Native Americans often used dried corncobs as ‘toilet paper’. This material is quite abundant, rich and soft, easy to absorb. Although the user may be a little sore, it is still considered safer and more comfortable than many other materials. 2. Snow For people living in cold areas, snow was a good candidate in a time when toilet paper wasn’t available. The only downside is probably the feeling of cold to the bone, but if you get used to it, no one will feel embarrassed because it is very clean. 3. Rocks It sounds unbelievable, but there were times when people used stones for cleaning. The advantage of this type of “toilet paper” is that it is easy to find, abundant. Just like the cob, although this is not the most comfortable material, it is at least very convenient when there is no other better material to replace it. 4. Wooden stick About 2000 years ago, people in ancient China used toilet sticks. This “toilet paper” is cut from bamboo and other woods, shaped like spoons. People call this tool salaka, cachou or chugi. The ends of the tools are covered with cloth to create a more comfortable feeling for the user. Even so, it still makes people shudder just thinking about it. 5. Broken ceramic shards Compared to the Chinese, the Greeks have even more creepy “toilet paper”. In ancient toilets, the Greeks used “pessoi” (small pieces of pottery) to clean after defecation. These ceramic pieces, usually 3-11 cm in diameter, are cut and angled from broken pottery. This material is so popular that the Greeks have an adage: “Three pieces are enough to wipe”. 6. Tersorium If the above materials are too hard and easily cause pain to the user, the Roman tersorium seems more comfortable. Tersorium is a cleaning device created by attaching sponges to a stick. Although there is no specific document on how to use it, many people think it is likely that tersorium is a toilet brush and not “toilet paper”. 7. Mussel shell People in the island and coastal areas often make use of natural resources as an alternative to “toilet paper”, despite the fact that they have many sharp edges. If there is no mussel shell, people will replace it with coconut shell. 8. Grass Grass and leaves are the softest method ever used by man in history. The advantage of this natural material is that it is easy to find, environmentally friendly and convenient. 9. Sand Different climatic conditions lead to different cleaning methods. In arid places, people are forced to use sand to replace toilet paper. This way is not very comfortable but is almost the only option for many people.

Here are very common mistakes in bathing every day. Bathing for too long Bathing for too long dries out the skin, leading to rashes and itching. The appropriate bathing time is about 10 minutes. Using too much shower gel The more foam the shower gel has, the more surfactant it contains. Overusing it will deplete your skin’s natural protective oils, leading to dryness and roughness. In addition, if your skin is allergic or the product is not specifically designed for you, do not use them every day. Old and wet bath cotton Wet sponges and loofahs are often a breeding ground for bacteria and mold, so they should be changed every 4 weeks. Try using cotton bath gloves. It is also important to dry the sponge after use to avoid bacterial growth. Wipe people too dry It is not good for the skin to be too dry by scrubbing too hard. So, wipe your body with a soft towel and leave the skin slightly damp. Then, apply moisturizer to the necessary areas of the skin, making the skin smooth and healthy. The water is too hot Too much hot water will make the skin dry and flaky because it washes away all the oils present on the skin, leaving the skin defenseless. This will also increase blood flow, causing the skin to become red, inflamed, and rash. Bath water at around 35 – 40°C is perfect for healthy skin.

“Bath sponges are considered bacteria bags, as are daily face towels. Items that are hung in a humid place easily create an environment for bacteria to grow. Hard sponge bath products can causing tears while the user washes his face,” he said. Bath sponge made of loofah. Photo: Huff Post. In fact, 98% of dermatologists warn against using bath towels. Doctor J. Matthew Knight (Orlando, USA) shared in the newspaper New York Post that we should quit this habit because the use of the product is to remove dead skin on the body, but then the dead skin cells remain on the surface of the bath sponge, easy to appear mold. “During the bathing process, all kinds of bacteria and dead cells will be trapped in the bath sponge. Most of these bacteria are diverse in types. What they have in common is their vitality and intense reproduction. is at night,” he added. If you use a sponge after shaving, all the bacteria can get into the cuts and cause a skin infection. However, it is essential to clean it thoroughly after each use. After each bath, users need to dry the item in a dry place and should not hang it in wet areas such as the bathroom. In addition, the sponge must be changed regularly after 3 weeks. Absolutely do not use cotton bath when the body has pimples, wounds easily spread bacteria. Bath towels are home to many types of bacteria that are harmful to the body. Photo: Naver.

Berkeley Lab is pursuing negative emission technologies and related research to remove CO2 from the atmosphere. According to Jeffrey Long, senior scientist in the Berkeley Laboratory’s Materials Science Department, UC Berkeley Professor of Chemistry, MOFs are highly porous solid materials that act like a sponge. They are capable of absorbing large amounts of a specific gas molecule, like CO2. A special feature of MOFs is its high internal surface area. Therefore, if properly designed, a small amount of MOF can remove large amounts of CO2 from the flue gases produced during the burning of fossil fuels. “We have shown that MOFs can capture and release CO2, using a much smaller temperature change than is required by other technologies. This offers a great advantage over conventional methods of CO2 capture. Variations of MOF can be effective in removing CO2 from other gas mixtures, including biogas, natural gas and even directly from the air, ”explained Mr. Long. However, this expert emphasized, reducing the cost of direct gas collection is essential, because this process is extremely expensive. The cost of removing CO2 with such a technology is at 500 – 1,000 USD / ton. Therefore, Mr. Long said that in the future, researchers will create more efficient materials. As a result, it helps to reduce costs below 100 USD / ton. Besides, the main issue is the amount of energy required to regenerate the adsorbent. This means that the scientists want to release CO2 in its pure form. As a result, the material can then be reused to capture more CO2. “One of our research goals is to develop materials with high capacity, high capture rate, fast kinetics for CO2 adsorption and low regeneration temperature. At the same time, limit the co-adsorption of water so as not to waste energy on the desorption process “, Mr. Long said. According to the scientist, it is possible to find a way to achieve below $ 100 for each ton of CO2 removed from the air. However, scientists will have to do much of the research needed to achieve that. “We need to really rethink some of the ways materials are designed and understand how to manipulate things like delta-S (entropy) to adsorb CO2, so that less heat is needed to release CO2,” Mr. Long stressed.
