➀ Isu Petasys has decided to withdraw from its plan to acquire carbon nanotube manufacturer JEIO; ➁ The decision was personally ordered by Kim Sang Beom, the chairman of Isu Group; ➂ With the cancellation, Isu Petasys will be giving up the 15.8 billion won deposit that has already been paid.

1. Researchers in China developed multilayer porous PVC gel artificial muscles using carbon nanotube-doped 3D-printed silicone electrodes, showing potential in human-machine interaction, medical rehabilitation, and flexible electronics. 2. The study optimized the ink formulation for both the CNT-PDMS composite and PVC gel to achieve desired properties for 3D printing. 3. Performance testing demonstrated the actuator's high deformability and responsiveness, indicating its potential for practical applications.
