Advanced Science, EarlyView.This study introduces a self‐powered environmental monitoring system that integrates a triboelectric nanosensor (TENS) with a robotic hand, controlled remotely by an exo‐hand and powered by a thermoelectric generator (TEG). The fully autonomous system detects Pb2⁺, Cr⁶⁺, and As3⁺ ions in real‐time and operates without external power, ideal for remote ...

Cryo‐Inactivated Cancer Cells Derived Magnetic Micromotors for Tumor Immunotherapy
Advanced Science, EarlyView.Cryo‐inactivated cancer cell‐based magnetic micromotors are developed for synergistic tumor immunotherapy via magnetic targeting. These micromotors can induce ferroptosis and immunogenic cell death, deliver tumor antigens, and activate the Mn2+‐dependent cGAS‐STING pathway. The system effectively suppresses tumor progression, recurrence, and metastasis,

Estimation and Modelling of PCBs Bioaccumulation in the Adriatic Sea Ecosystem [PDF]
arXiv, 2014 Persistent Organic Pollutants represent a global ecological concern due to their ability to accumulate in organisms and to spread species-by-species via feeding connections. In this work we focus on the estimation and simulation of the bioaccumulation dynamics of persistent pollutants in the marine ecosystem, and we apply the approach for ...
