Soft polyurethane (PU) materials exhibit excellent structural stability, sound absorption and heat insulation, and they can be used to prepare multifunctional conductive composites with electromagnetic interference (EMI) shielding function. On the basis of a multistep assembly strategy, our study constructed composite foams with sound absorption and EMI shielding properties by designing different functional layers and expanded the application field of PU foam. First, carbon black particles are compounded with PU foam to improve the mechanical properties and conductivity of pure foam. Then, an aluminum layer and a knitted fabric layer were introduced to construct composite foam samples with a sandwich structure, endowing the materials with excellent EMI shielding performance. The resultant composite foam material exhibits effective EMI shielding performance and good sound absorption performance, which are 58.33 dB and >0.3, respectively. Moreover, the composite foam material demonstrates high bursting strength and compression resistance, suggesting that it can be used under different conditions. The employment of the multistep assembly strategy provides PU foam with a flexible range of applications, offering an innovative approach for preparing multifunctional conductive composite materials.

Adoptive cell therapy (ACT) is a rapidly growing anti‐cancer strategy that has shown promise in treating various cancer types. The concept of ACT involves activating patients’ own immune cells ex vivo and then transferring them back to the patients to recognize and eliminate cancer cells. Currently, the commonly used ACT includes tumor‐infiltrating lymphocytes (TILs), genetically engineered immune cells, and dendritic cells (DCs) vaccines. With the advancement of cell culture and genetic engineering techniques, ACT has been used in clinics to treat malignant hematological diseases and many new ACT‐based regimens are in different stages of clinical trials. Here, representative ACT approaches are introduced and the opportunities and challenges for clinical translation of ACT are discussed.
