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.

Oil prices rose on Wednesday as industry data showed a larger-than-expected drawdown in U.S. crude stockpiles, while expectations for an extended shutdown of a major North Sea crude pipeline also continued to bolster markets. Britain’s biggest pipeline from its North Sea oil and gas fields is likely to be shut for several weeks for repairs. On Wednesday morning, its operator said it was still considering repair options and reiterated that any repairs would take several weeks. Click Read More below for additional information.

“Trends is an important record of how the trucking industry is performing,” said ATA Chief Economist Bob Costello. “That’s why it is on the shelves of business leaders and policymakers across North America. “This year’s edition shows that 2023 was a very challenging year, but the industry weathered the storm, moving more than 11 billion tons of freight during the year,” he said. Among the key findings in this year’s report: *Preliminary figures indicate that trucks moved 11.18 billion tons of freight in 2023, down from the 11.46 billion tons hauled the previous year. *Preliminary figures indicate that the industry saw revenues grow to $987 billion, up from $940.8 billion in 2022. *Trucking employed 8.5 million people in industry-related jobs, including 3.55 million professional drivers in 2023. *The industry remains one made up of small businesses, with 95.5% of carriers operating 10 or fewer trucks and 99.6% operating fewer than 100 power units. *Cross-border trade remained a robust source of freight for motor carriers, with trucks moving 66.5% of surface trade between the US and Canada, and 84.5% of goods across the Mexican border in 2023.
