Graphene-coated copper nanowire networks are presented as highly stable transparent electrodes suitable for harsh environments, significantly enhancing the efficiency of electrocatalytic hydrogen evolution reactions. The study highlights the material's robustness and potential applications in advanced energy systems.

Didi, China's leading ride-hailing company, faces a severe crackdown from Chinese authorities, including a cybersecurity review and app removal orders, which could lead to a loss of nearly 6 million new users. The company's stock price plummeted by 30% within a week, affecting American investors and sparking heated discussions among Chinese netizens. The crackdown is seen as part of the Chinese government's broader strategy to control private tech giants and their capital. Didi's rush to list in the U.S. despite warnings from authorities is viewed as a defiance that led to the current predicament. The Chinese government is also tightening regulations on data security and overseas listings, with new laws such as the Cybersecurity Law and the upcoming Data Security Law and Personal Information Protection Law. Analysts believe the crackdown is less about cybersecurity and more about political control over private enterprises and their data.

China's Producer Price Index (PPI) for May has seen a significant year-on-year increase of 9%, the highest in nearly 13 years, indicating substantial cost pressures on the manufacturing sector due to rising international raw material prices. The Chinese government is actively implementing measures to curb these pressures, including combating price gouging, providing subsidies to businesses, and considering releasing national metal reserves. Experts interviewed by Voice of America suggest that the People's Bank of China may allow the yuan to appreciate to alleviate import costs but are unlikely to significantly tighten monetary policy to avoid harming economic recovery. Despite high raw material and production prices, consumer prices have remained stable, with the Consumer Price Index (CPI) increasing by only 1.3% year-on-year in May. However, there is skepticism about the official price indices reflecting the actual consumer experience. The Chinese government is aware of the potential inflationary pressures from PPI to CPI and has introduced measures to prevent a consumer price crisis that could hurt economic recovery.
