Plastic for household recycling

20.08.2021

San Francisco-based startup Intropic Materials has developed a plastic that can be composted at home. The new material differs in that it is able to decompose very quickly, it takes from several days to several weeks, depending on the decomposition conditions and the state of the compost, including its temperature.

The fundamental difference between the new degradable plastic is that it already contains special enzymes, thanks to which it decomposes. Typically, such enzymes are produced by microorganisms, thereby triggering the decomposition process. But in the new plastic, the enzymes are activated on their own when conditions of temperature and humidity favor it. As a result, the material begins to quickly break down, eventually turning into fertilizer (of course, if it is put into a compost heap).

The new plastic, which biodegrades quickly, could be very useful for diners and other similar businesses. After all, this material can not only be composted, but also recycled, since it breaks down into monomers. Enterprises will be able to create local systems for the decomposition of this plastic in order to send monomers for recycling in the future. As a result, it will be possible to make new plastic from such raw materials, so that the degradable material will support the full cycle of its use and recycling.

It is planned to confirm the ability of the new plastic to decompose in the laboratory, and then it will be necessary to test this material in real conditions. At the same time, they plan to start with those materials that are usually not recyclable, primarily with plastic bags and films.

The new plastic could be especially useful in countries that don't have a well-developed composting infrastructure, as it can decompose even at home.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

Energy from space for Starship 08.05.2024

Producing solar energy in space is becoming more feasible with the advent of new technologies and the development of space programs. The head of the startup Virtus Solis shared his vision of using SpaceX's Starship to create orbital power plants capable of powering the Earth. Startup Virtus Solis has unveiled an ambitious project to create orbital power plants using SpaceX's Starship. This idea could significantly change the field of solar energy production, making it more accessible and cheaper. The core of the startup's plan is to reduce the cost of launching satellites into space using Starship. This technological breakthrough is expected to make solar energy production in space more competitive with traditional energy sources. Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

What sticks to teflon 15.06.2006

As you know, nothing sticks to Teflon, so pans, tablecloths and ties are covered with it. However, employees of the University of Erlangen (Germany) found substances sticking to this ultra-smooth plastic.

They turned out to be some expensive chemical catalysts containing, like Teflon, fluorine atoms. So, in order to capture the catalyst from the reagent solution in order to reuse it, it is enough to pass the mixture over a Teflon tape.
