New design of high voltage surge arresters [PDF]
, 2004 Zinc-oxide material is an important and widely used element in the high voltage gapless surge arresters. Equally important is the usually polymeric insulating material used for the surge arrester housing. This work aims to develop a new design of gapless

The Anatomical Record, EarlyView.Abstract Prozostrodon brasiliensis, a probainognathian cynodont of the clade Prozostrodontia, is recognized as a key taxon for understanding the origin of Mammaliaformes and mammals. Despite detailed investigations of its cranial anatomy, the postcranial skeleton has received comparatively less attention.

British Educational Research Journal, EarlyView.Abstract This study examines the under‐theorized political role and identity of Chinese international students, who emerge as significant actors caught between U.S. soft power ambitions and rising geopolitical suspicion. Amid escalating U.S.‐China tensions, these students are forced to confront environments shaped by competing geopolitical discourses ...

Harnessing ferroptosis from multilayer defense networks to nanoplatforms for specific cancer therapy
BMEMat, EarlyView.Nanomaterials target metabolically‐regulated ferroptosis for cancer therapy. Iron‐based or alternative nanoplatforms integrate ferroptosis with chemotherapy, immunotherapy, or radiotherapy. They enable stimulus‐responsive therapies (photothermal, photodynamic, sonodynamic) activated by near‐infrared, light, or ultrasound, achieving potent synergistic ...

Development of High Gradient ZnO Arrester Material for High Voltage Applications
IEEE Access, 2020 The presence of stray capacitance in ZnO (Zinc Oxide) surge arresters causes hurdles in arrester operation and non-uniform voltage distribution along the arrester column, especially for High Voltage (HV) and Extra high voltage (EHV) applications.

Archives of Metallurgy and Materials, 2020 The paper presents results of investigation of microstructure and micro-hardness for material of ZnO varistors applied to 110 kV surge arrester and surge arrester counter. The research combined two pairs of varistors, each consisted of one varistor subjected before to operation, while the other one was brand new unit and constituted a reference.
