Zero Yield Aviation Fuel Production

04.12.2022

An interdisciplinary team of researchers at Worcester Polytechnic Institute (WPI) has developed a potential breakthrough in sustainable aviation: a zero-fuel recipe for aircraft that extracts carbon dioxide (CO2) from the air.

Led by Jagan Jayachandran, Associate Professor, Department of Aerospace Engineering, and Adam Powell, Associate Professor, Department of Mechanical and Materials Engineering, the work is helping to address the urgent challenge of climate change. According to the International Council for Clean Transportation (ICCT), aviation is responsible for approximately 2,5% of all global greenhouse gas emissions and this figure is expected to rise.

"As aviation grows, so will industrial emissions," says Powell. "We need to think outside the box and look at sustainable materials that will contribute to a long-term solution to reduce the transport sector's carbon footprint."

Through modeling and computational analysis, Jayachandran and Powell developed a formula for a fuel composed of magnesium, the world's most abundant mineral in the world's oceans. A slurry of magnesium hydride - a chemical compound made up of magnesium and hydrogen - mixed with a hydrocarbon fuel would burn to form CO2, water vapor and magnesium oxide (MgO) nanoparticles.

Magnesium hydride fuel will also provide aircraft with long-haul range, such as from Boston to Tokyo, which is a problem with other sustainable aviation fuels. This greater range is achieved in part due to the chemical properties of the slurry - combustion requires less volume than typical aviation fuel.

"We have found that this fuel will have 8% more range than other modern jet fuels and more than two to three times the range of liquid hydrogen or ammonia that other researchers have proposed as clean fuels." Jayachandran noted.

The Department of Energy describes sustainable aviation fuel as "a biofuel used to power aircraft that has properties similar to conventional jet fuel, but with a lower carbon footprint." This biofuel is produced from resources such as corn grain, algae, forestry and agricultural waste. The use of biofuel as a hydrocarbon in this magnesium hydride slurry can result in net negative emissions.

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 ... >>

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, ... >>

Magnetic material properties: from insulator to metal 13.03.2014

Scientists at the University of California, San Diego have created a material whose magnetic properties change dramatically with temperature. A description of the new material was presented at a conference of the American Physical Society held in Denver.

Thin-film vanadium oxide and nickel were used as the basis for the material. Vanadium oxide, as shown by the authors earlier, changes the properties of conductivity with a slight change in temperature. It is an insulator at low temperatures, and if a certain threshold is exceeded, it begins to exhibit the properties of a metal.

"We have learned to control the magnetic properties of the material without using a magnetic field. In principle, this control can be carried out using electric current or voltage," Ivan Shuler, one of the authors of the work, explained the properties of the created material. So far, the authors have managed to change the magnetic properties of the material using laser irradiation. In the range of only 20°, its "resistance" to the magnetic field (coercivity) changed by almost 5 times.

According to scientists, the study of new material can become an incentive for the creation of new magnetic carriers. In addition, on the basis of a material with similar characteristics, it is possible to create transformers that will be resistant to shock loads.
