Revealing the Mutually Enhanced Mechanism of Necroptosis and Immunotherapy Induced by Defect Engineering and Piezoelectric Effect

Advances in Materials, 2023
Owing to low immunogenicity‐induced immune escape and short‐term circulating immune responses, the efficiency of immunotherapy is unsatisfactory. Therefore, triggering immunogenic cell death and establishing a long‐term, mutually reinforced treatment ...

Ionic Liquids Exhibit the Piezoelectric Effect.

Journal of Physical Chemistry Letters, 2023
The piezoelectric effect was discovered over a century ago, and it has found wide application since that time. The direct piezoelectric effect is the production of charge upon application of force to a material, and the converse piezoelectric effect is a
