Hybrid Resonant DC–DC Converters for DC Transformers in DC Distribution Networks With Limited Reverse Power Flow Range

IEEE Access
In DC distribution networks integrating distributed generation, DC transformers (DCT) exhibit asymmetric forward and reverse power flows, with reverse power flow range being limited. Based on this characteristic, this paper proposes a hybrid resonant (HR)

CD44‐Targeting Hydroxyapatite Nanoparticles (HAP) Induce Mitochondrial Dysfunction‐Driven PANoptosis and Immunogenic Cell Death (ICD) via Ca Overload in Colorectal Cancer

Advanced Science, EarlyView.
ABSTRACT Colorectal cancer (CRC) remains therapeutically challenging due to high metastasis, recurrence, and immunotherapy resistance driven by tumor microenvironment‐mediated immune evasion. Immunogenic cell death (ICD) offers a promising strategy to reshape the immune microenvironment, yet existing ICD inducers suffer from poor targeting efficiency ...
