Paraffin wax (PW) has significant potential for spacecraft thermal management, but low thermal conductivity and leakage issues make it no longer sufficient for the requirements of evolving spacecraft thermal control systems. Although free-state expanded graphite (EG) as a thermal conductivity enhancer can ameliorate the above problems, it remains challenging to achieve higher thermal conductivity (K) (>8 W/(m·K)) at filler contents below 10 wt.% and to mitigate the leakage problem.

Given these challenges, there is an urgent need for innovative imaging systems that not only excel in detection performance but are also compact, cost-effective, and ensure safety for biomedical applications. In response to these requirements, our research introduces an advanced terahertz (THz) microbolometer array imaging system (MAIS), specifically engineered for biomedical detection.

However, the majority of patients eventually develop resistance, and the disease is further complicated by its "cold" tumor microenvironment, characterized by low tumor immunogenicity and limited CD8+ T cell infiltration. These factors contribute to the poor response to immunotherapy in many cases of extensive-stage SCLC (ES-SCLC).

Histidine triad nucleotide-binding protein 2 (HINT2) has been implicated in the development of various diseases, whereas its involvement in the progression of AP remains unclear. This study aims to investigate the role of HINT2 in AP.
