Selective two-electron and four-electron oxygen reduction reactions using Co-based electrocatalysts Chemical Society Reviews ( IF 40.4 ) Pub Date : 2025-04-22 , DOI: 10.1039/d4cs01199f The oxygen reduction reaction (ORR) can take place via both four-electron (4e−) and two-electron (2e−) pathways. The 4e− ORR, which produces water (H2O) as the only product, is the key reaction … Read more
ChemSocRev (Chemical Society Reviews) is a leading journal published by the Royal Society of Chemistry, featuring high-impact, authoritative, and highly readable review articles. Since its inception in 1947 as the Quarterly Review of the Chemical Society, ChemSocRev has published many influential review papers over the past 70 years, growing to become one of the most … Read more
The oxygen reduction reaction (ORR) is crucial in fuel cells and metal-air batteries. It proceeds via both four-electron and two-electron pathways, producing water and hydrogen peroxide, respectively. Precise control over ORR selectivity is key. Cobalt-based electrocatalysts have become a research hotspot due to their high activity, low cost, and ease of synthesis. High selectivity can … Read more
Background Introduction In embedded systems, UART serial ports are commonly used for debugging and communication. Typically, there are no specific requirements for the baud rate of the debugging serial port, with a common configuration being 115200 8N1. Besides debugging, UART serial ports can also serve as data communication interfaces for interconnecting with other boards or … Read more
Intel unveiled its next-generation SoC at the Shanghai Auto Show. On April 23, Intel participated in the Shanghai Auto Show for the first time, launching the second-generation AI-enhanced Software Defined Vehicle System-on-Chip (SDV SoC). The chip is designed based on a Chiplet architecture, focusing on smart cockpit and autonomous driving scenarios. It supports generative AI … Read more
As 2025 begins, the most remarkable segment in the semiconductor industry is undoubtedly the SoC track. A performance report from Rockchip has ignited market enthusiasm: Q1 net profit reached 200-225 million yuan, a year-on-year increase of 196%-233%. The non-recurring net profit is even closer to 100% of the main contribution, completely dispelling market doubts about … Read more
For most System-on-Chip (SoC) designs, the most critical task is not RTL coding, nor is it creating the chip architecture. Nowadays, SoCs are primarily designed by assembling various silicon Intellectual Property (IP) modules from multiple vendors. This makes managing silicon IP a major task in the design process. Generally speaking, in new SoC designs, less … Read more
[Image]SoC Security Design and Modeling⊙Integrated Circuits ⊙Security ⊙Modeling Protecting System Security[Image]In modern computing systems, the hardware and software stack coordinate with each other to achieve system functionality. Previous research has primarily focused on the security issues of the hardware itself, without addressing another important aspect of hardware security, which is providing the infrastructure for secure … Read more
Using serial ports to print debugging information is a common debugging method, known for its simplicity and ease of use, but it also has significant limitations:– It does not support advanced features such as breakpoints, single-step tracing, and memory read/write.– Excessive printed debugging information can impact performance, while too little information may be insufficient to … Read more
The Internet of Things (IoT) continues to transform various industries, making design decisions around wireless connectivity components increasingly complex. Engineers often face a dilemma when selecting components for their IoT applications, having to choose between IC and wireless modules. Both options have unique advantages and trade-offs that impact design complexity, cost, scalability, and time to … Read more
