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.

American Trucking Associations’ advanced seasonally adjusted (SA) For-Hire Truck Tonnage Index decreased 0.3% in April after increasing 2.3% in March. In April, the index equaled 114.7 (2015=100) compared with 115.1 in March. “After a revised increase in March of 2.3%, the April index declined just slightly,” said ATA Chief Economist Bob Costello. “The outlook is solid for tonnage going forward as the country approaches pre-pandemic levels of activity, with strong economic growth in key areas for trucking – including retail, home construction and even manufacturing. “Additionally, the index increased on a year-over-year basis for the first time since March 2020. Part of the reason for the gain was due to an easy comparison with when the index fell significantly in April 2020,” he said. “But I’m expecting increases, albeit smaller than April’s, on a year-over-year basis going forward. Trucking’s biggest challenges are not on the demand side, but on the supply side, including difficulty finding qualified drivers.”

The American Trucking Associations welcomed five major new federal investments by the Department of Transportation that will add approximately 1,000 truck parking spaces and make it easier for drivers to locate parking along key freight corridors in Florida, Missouri, Pennsylvania, California, Oregon, Washington and Wisconsin. “The severe shortage of truck parking continues to rank among drivers’ highest concerns, which is why we appreciate that Secretary Buttigieg and a growing number of states are making these projects a top priority,” said ATA President and CEO Chris Spear. “America’s highways are our shop floor. When drivers finish their shift, they deserve to know that they will be able to find a safe place to sleep that night. These significant investments in expanding parking capacity along some of America’s busiest freight corridors will help reduce supply chain bottlenecks, alleviate stress on truck drivers and make the roadways safer for all motorists.”
