AAA Daily Fuel Gauge Report for Friday, 3/18/22

American Trucking Associations’ advanced seasonally adjusted (SA) For-Hire Truck Tonnage Index decreased 2% in April after rising 1.8% in March. In April, the index equaled 115.8 (2015=100) versus 118.2 in March. “After eight straight gains totaling 6.9%, for-hire tonnage finally slid back in April. Despite being the largest sequential drop since August 2020, the index was still above where it started in 2022 and a year earlier,” said ATA Chief Economist Bob Costello. “It is important to note that ATA’s for-hire tonnage data is dominated by contract freight with minimal amounts of spot market loads. The spot market has softened more than for-hire contract freight, as the market transitions back to pre-pandemic shares of contract versus spot market," Costello said.

Carbon aerogels are ultralight, conductive materials, which are extensively investigated for applications in supercapacitor electrodes in electrical cars and cell phones. Chinese scientists have now found a way to make these electrodes sustainably. The aerogels can be obtained directly from cellulose nanofibrils, the abundant cell-wall material in wood, finds the study reported in the journal Angewandte Chemie. Supercapacitors are capacitors that can take up and release a very large amount of energy in a very short time. Key requirements for supercapacitor electrodes are a large surface area and conductivity, combined with a simple production method. Another growing issue in supercapacitor production—mainly for smartphone and electric car technologies—is sustainability. However, sustainable and economical production of carbon aerogels as supercapacitor electrode materials is possible, propose Shu-Hong Yu and colleagues from the University of Science and Technology of China, Hefei, China.
