A team of researchers affiliated with several institutions in the U.K. and one in Saudi Arabia has developed a way to produce jet fuel using carbon dioxide as a main ingredient. In their paper published in the journal Nature Communications, the group describes their process and its efficiency.
As scientists continue to look for ways to reduce the amount of carbon dioxide emitted into the atmosphere, they have increasingly focused on certain business sectors. One of those sectors is the aviation industry, which accounts for approximately 12% of transportation-related carbon dioxide emissions. Curbing carbon emissions in the aviation industry has proved to be challenging due to the difficulty of fitting heavy batteries inside of aircraft. In this new effort, the researchers have developed a chemical process that can be used to produce carbon-neutral jet fuel.
The researchers used a process called the organic combustion method to convert carbon dioxide in the air into jet fuel and other products. It involved using an iron catalyst (with added potassium and manganese) along with hydrogen, citric acid and carbon dioxide heated to 350 degrees C. The process forced the carbon atoms apart from the oxygen atoms in CO2 molecules, which then bonded with hydrogen atoms, producing the kind of hydrocarbon molecules that comprise liquid jet fuel. The process also resulted in the creation of water molecules and other products.
Scientists in China claim to have built a hypersonic jet engine—called “sodramjet”—that can fly at 16 times the speed of sound. This means that an aircraft kitted out with such engines could fly anywhere in the world in two hours, according to the scientists. The test flight of a prototype was carried out in a wind tunnel in Beijing, China, and displayed excellent thrust, fuel efficiency, and operational stability. Led by Professor Zonglin Jiang of the Chinese Academy of Sciences’ Institute of Mechanics, the team’s findings were published in Chinese Journal of Aeronautics on Saturday.

Federal officials are disappointed to find that the monoclonal antibody drugs they’ve shipped across the country aren’t being used rapidly.
These drugs are designed to prevent people recently diagnosed with COVID-19 from ending up in the hospital. But hospitals are finding it cumbersome to use these medicines, which must be given by IV infusion. And some patients and doctors are lukewarm about drugs that have an uncertain benefit.
Doctors hope that as word gets out, more people will end up trying these drugs. They are provided to health systems free by the federal government, but it costs money to administer the medication. At first, Medicare set a price that would require many patients to pay a $60 copay, but the Centers for Medicare and Medicaid Services later found a way to waive that fee.
Monoclonal antibodies to prevent severe COVID-19 aren’t being used as widely as expected. Medical staff shortages and patient transportation problems are two of the reasons.

Apple’s first passenger car could include its own breakthrough battery technology.
Apple is actively working on various automotive projects that could ultimately lead to an “Apple Car” and is targeting 2024 to produce a passenger vehicle.
When it comes to the semiconductor industry, silicon has reigned as king in the electronics field, but it is coming to the end of its physical limits.
To more effectively power the electrical grid, locomotives and even electric cars, Lawrence Livermore National Laboratory (LLNL) scientists are turning to diamond as an ultra-wide bandgap semiconductor.
Diamond has been shown to have superior carrier mobility, break down electric field and thermal conductivity, the most important properties to power electronic devices. It became especially desirable after the development of a chemical vapor deposition (CVD) process for growth of high-quality single crystals.
