Nanocatalytic Immunotherapy Targeting Tumor‐Resident Intracellular Bacteria for Triple‐Negative Breast Cancer Treatment and Metastasis Suppression

open access: yesAdvanced Science, EarlyView.
Bacteria residing within tumor cells contribute to breast cancer progression, but few therapies target their elimination. FeSe2 nanosheets coated with cancer cell membranes accumulate in tumors and generate reactive oxygen species under ultrasound, killing tumor cells and their harbored bacteria at the same time.

Silicon Nitride Resistive Memories

open access: yesAdvanced Electronic Materials, EarlyView.
Amorphous SiNx is an attractive resistance switching material for ReRAM applications due to its physicochemical properties, such as humidity resistance, low oxygen diffusivity, and is used as a metal diffusion blocker. By modifying the ratio between N and Si atoms, the microstructure of the SiNx is affected, rendering it possible to change the ...
