Glad to see there is a real effort underway to create and work to manufacture nanoscale structures that can serve as alternatives to rare earth materials given all the controversy over their ability. Obviously, as we have seen from the pursuit of alternative fuel and EV battery technologies, this kind of innovation process takes time and with every win, there is a setback. All part of the process, however, and I'm glad to see that are myriad efforts underway. The wider range of projects on the table, the better the shot that one of them will be on the money.
The implementation of a new diesel fuel standard in the US has considerably improved the environmental performance of diesel vehicles. The Environmental Protection Agency (EPA) says that the new ultra-low sulfur diesel (ULSD) fuel has combined with other improved technologies to reduce diesel's particulate matter (PM) emissions by 99%.
