For the first time, scientists have identified the 100 transnational corporations (see table) extracting the majority of revenues from economic use of the world s ocean.
Dubbed the Ocean 100 , the group of companies generated US$1.1 trillion in revenues in 2018, according to the research published in the journal
Science Advances. If the Ocean 100 was a country it would be the 16th largest on Earth, said Henrik Österblom, a co-author on the study from Stockholm Resilience Centre at Stockholm University. By revenue, the Ocean 100 is equivalent to the GDP of Mexico.

Scientists in China and Sweden have determined that a pinch of capsaicin, the chemical compound that gives chili peppers their spicy sting, may be a secret ingredient for more stable and efficient perovskite solar cells. The research, published January 13 in the journal
Joule, determined that sprinkling capsaicin into the precursor of methylammonium lead triiodide (MAPbI3) perovskite during the manufacturing process led to a greater abundance of electrons (instead of empty placeholders) to conduct current at the semiconductor s surface. The addition resulted in polycrystalline MAPbI3 solar cells with the most efficient charge transport to date. In the future, green and sustainable forest-based biomaterial additive technology will be a clear trend in non-toxic lead-free perovskite materials, says Qinye Bao, a senior author of the study from East China Normal University. We hope this will eventually yield a fully green perovskite solar cell for a clean energy so

ORLANDO, Jan. 12, 2021 -Vehicles have evolved to become more efficient and sophisticated, but their fuel hasn t necessarily evolved along with them. The Department of Energy is determined to identify cleaner burning and renewable alternatives to gasoline, and through the work of two UCF researchers, the DOE is one step closer to that goal.
Research engineer Anthony C. Terracciano and Associate Professor Subith Vasu have developed a model that will help engine designers, fuel chemists and federal agencies determine whether certain biofuels should be implemented as an alternative fuel for vehicles.
The research was conducted as part of the DOE s Co-Optimization of Fuels and Engines initiative, better known as Co-Optima. Findings were recently published in Nature

To resolve the energy crisis and environmental issues, research to move away from fossil fuels and convert to eco-friendly and sustainable hydrogen energy is well underway around the world. Recently, a team of researchers at POSTECH has proposed a way to efficiently produce hydrogen fuel via water-electrolysis using inexpensive and readily available nickel as an electrocatalyst, greenlighting the era of hydrogen economy.
A POSTECH research team led by Professor Jong Kyu Kim and Ph.D. candidate Jaerim Kim of the Department of Materials Science and Engineering and a team led by Professor Jeong Woo Han and Ph.D. candidate Hyeonjung Jung of the Department of Chemical Engineering have join

WASHINGTON, January 12, 2021 Sodium-ion batteries are a potential replacement for lithium batteries, but the anodes positively charged electrodes that work well for lithium-ion batteries don t provide the same level of performance for sodium-ion batteries.
Amorphous carbon, which lacks a crystalline structure, is known to be a useful anode, because it has defects and voids that can be used to store sodium ions. Nitrogen/phosphorus-doped carbon also offers appealing electrical properties.
