A new study shows that a retrieval-augmented generation-based intelligent learning companion can significantly enhance students’ practical skills and flow experience in analog circuit laboratory instruction. While the system does not replace teachers in conceptual or emotional guidance, it provides highly accurate, real-time support that strengthens hands-on learning and engages students more deeply during experiments.

Direct air capture (DAC) is an emerging technology aimed at mitigating global warming. However, conventional DAC technologies and the subsequent utilization processes are complex and energy-intensive. An integrated system of direct air capture and utilization (IDACU) via in-situ catalytic conversion to fuels and chemicals is a promising approach, although it remains in the early stages of development. This review examines the current technical routes of IDACU, including solid-based dual-functional materials (DFMs) through thermo-catalysis, IDACU using liquid sorbents with thermo-catalysis, and non-thermal conversion methods. It covers the basic principles, reaction conditions, main products, material types, and the existing problems and challenges associated with these technical routes. Additionally, it discusses the recent advancements in solid-based DFMs for IDACU, with particular attention to the differences in material characteristics between carbon capture from flue gases (ICCU) and DAC. While IDACU technology holds significant promise, it still faces numerous challenges, especially in the design of advanced materials.

A team of researchers from the University of Science and Technology of China (USTC) has published a comprehensive review in Science China Chemistry, highlighting the latest breakthroughs in "top-down" synthesis strategies for single-atom catalysts (SACs). Led by Prof. Huang Zhou and Prof. Yuen Wu from USTC’s Key Laboratory of Precision and Intelligent Chemistry and Deep Space Exploration Laboratory, the review systematically summarizes a decade of progress in the field, offering valuable insights for advancing SACs’ practical application.

Cybersecurity has always been the focus of Internet research. Malware refers to software intentionally designed to harm computer systems, networks, or users by stealing, corrupting data, disrupting operations, or gaining unauthorized access. Existing malware traffic detection techniques rely on a sufficient amount of labeled data readily available for model training, limiting the capability of transferring to new malware detection.

Nowadays, vast and rapidly growing information acts as digital records of social activities and is widely collected and stored as economic assets. To reduce the difficulty and local data management’s cost significantly, cloud storage services provide a highly available, high-performance, and low-cost solution for user data hosting, enabling remote access, backup, and sharing of data stored by the cloud. However, this service model is not without security risks, including user privacy exposure, low trustworthiness of data, and unauthorized access. To address these concerns, attribute-based encryption
